PPA for boost
by legalize+jeeves＠mail.xmission.com 28 Feb '18

28 Feb '18

[Please do not mail me a copy of your followup] Hello fellow boosters, I am one of the maintainers of the C++ language track on exercism.io. When I first implemented this language track, we didn't have good regex support in g++'s standard library yet, so we needed boost.regex to fill that gap. Since we were already going to use boost.regex, I used boost.test for the unit test support. At the time, I found a PPA that was providing prebuilt binaries for ubuntu. Since that time, the need for boost.regex has gone away because the standard library implementation has been completed for g++. Along the way, the biggest source of problems in getting people going with C++ has been boost. For Windows users, it's annoying that CMake won't "just find" boost when you install it because there's no uniform mechanism between boost, packaging and CMake to say where boost got installed. For Mac users, they end up having difficulty with homebrew and fighting with Xcode. For Linux users, the PPA has gone stale and they end up being forced to build from scratch and get sent off into a ditch. In the meantime, we've got conan at stable 1.0 version right now, but that introduces a python dependency and then a conan dependency and for beginners I don't know if that's a path less fraught with peril. We've done some work on a branch to ditch boost.test and therefore boost entirely and switch the unit test framework to Catch. We have yet to "drop the hammer" on that and bring it onto master because reasons. (I am not the developer of that branch, but I suspect it hasn't happened yet because of the other integration issues that are needed; namely a bunch of documentation has to be updated and there will be teething pains with anyone who has already downloaded existing exercises and written them against boost.test.) Now, I find it hard to believe that I am the only one that has suffered from these issues all this time. Sure, if you only use header-only libraries then you don't need to build anything, but there are more than a few libraries in boost that either require or benefit significantly from being compiled. In all this time, have we not managed to come up with a stable, reliable PPA archive with ongoing support for boost for linux users? All I seem able to find are half-heartedly maintained PPAs with stale versions of boost on them. I have even tried to navigate going about setting up my own PPA in order to solve the problem myself, but I found launchpad.net and the whole PPA process so poorly documented and explained that I couldn't make head-nor-tails of it and gave up. (And this is coming from someone who has done more than my fair share of packaging and installer work on multiple platforms.) -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Terminals Wiki <http://terminals-wiki.org> The Computer Graphics Museum <http://computergraphicsmuseum.org> Legalize Adulthood!

Missing libs
by Tim Burgess 28 Feb '18

28 Feb '18

Hi, I downloaded the modular Boost master from Git Hub, as per instructions and built it on Windows as follows: .\Bootstrap .\b2 headers .\b2 This generated (amongst others) the following libs for boost::filesystem: libboost_filesystem-vc141-mt-gd-x32-1_67.lib libboost_filesystem-vc141-mt-gd-x64-1_67.lib libboost_filesystem-vc141-mt-x32-1_67.lib libboost_filesystem-vc141-mt-x64-1_67.lib I then tried to build a static release X64 version of my application using VS2017 and got: 1>LINK : fatal error LNK1104: cannot open file 'libboost_filesystem-vc141-mt-s-x64-1_67.lib' Obviously, I don't have this file, though I had thought that .\b2 was supposed to build all targets. So, I tried: .\b2 link=static This still does not generate the required file - where am I going wrong, please? BTW, I have checked that my project's library path points to the appropriate boost\stage\lib folder. Best wishes. Tim Burgess

[Thread] Version 1.66.0 incompatible with ISOLATION_AWARE_ENABLED
by Jim Wilburn 28 Feb '18

28 Feb '18

I work on a Windows code base that I have been updating from Boost 1.64.0 to Boost 1.66.0. One of the projects sets ISOLATION_AWARE_ENABLED to 1 (refer to https://msdn.microsoft.com/en-us/library/windows/desktop/bb773175(v=vs.85).…) #define ISOLATION_AWARE_ENABLED 1 The project also includes <boost/thread.hpp>. The Windows SDK version is 10.0.16299.0. The include chain is: <boost/thread.hpp> <boost/thread/thread.hpp> <boost/thread/thread_only.hpp> <boost/thread/win32/thread_data.hpp> <boost/thread/win32/thread_primitives.hpp> <boost/detail/winapi/dll.hpp> <boost/winapi/dll.hpp> The last include contains constructions such as: BOOST_SYMBOL_IMPORT boost::winapi::HMODULE_ WINAPI LoadLibraryA(boost::winapi::LPCSTR_ lpFileName); With a nonzero ISOLATION_AWARE_ENABLED, this results in redefinition errors, e.g.: .../boost/winapi/dll.hpp(38): error C2375: 'IsolationAwareLoadLibraryA': redefinition; different linkage ...\include\10.0.16299.0\um\winbase.inl(287): note: see declaration of 'IsolationAwareLoadLibraryA' Jim Wilburn

all roots of a polynomial
by mdebonis 22 Feb '18

22 Feb '18

Hello, I found Boost while searching for a C++ library which can do accurate polynomial root finding. The problem is that the documentation does not make it very clear how to implement this tool. Does anyone by any chance have some sample code on implementing this feature or steer me in the direction of an example in the documentation? I would like to use the best decimal place accuracy (it appears that you can get 50-place here?) Thanks! -- Sent from: http://boost.2283326.n4.nabble.com/Boost-Users-f2553780.html

Boost improperly including NTVERP.H
by Brian Catlin 22 Feb '18

22 Feb '18

Boost 1.66.0 is causing the Windows file NTVERP.H to be included (defining macros such as VER_DEBUG, VER_PRODUCTVERSION_STR, etc), preventing the definition of those macros by the application. This behavior didn't exist in 1.65.1, and breaks a standard Windows paradigm (it is very common for a Windows program to have a Version.h file containing the version resource macros (that are also defined in NTVERP.H), and then include Version.h in the main CPP file and the Resources.RC file). The NTVERP.H file contains the version information for the Windows SDK, and should NOT be included in an application! NTVERPH.H is included in: boost.1.66.0.0\lib\native\include\boost\predef\platform\windows_uwp.h boost.1.66.0.0\lib\native\include\boost\winapi\config.hpp

Serialization of optional<std::string>
by Chardrazle 21 Feb '18

21 Feb '18

As part of upgrading a product to a later version of boost the compilation has tripped up on serialization of a boost::optional<std::string>. The /optional.hpp/ header now has the comment: ...and this fires for std::string. What, if any, is the recommended way forward for this? An example code snippet to illustrate: Previous version of boost: 1.50; new: 1.6x Compiling with g++ 4.6.4 (although same problem with 4.8.5): -W -Wall -std=c++0x...

Math and numerics: Odeint - problem with adaptive step size
by William Heitler 20 Feb '18

20 Feb '18

Hello, I'm a moderately experienced C++ programmer using Visual Studio 2017, but I'm new to using the boost odeint library. I'm trying to integrate the Hodgkin-Huxley equations, which are a set of ODEs that describe the generation of nerve impulse. The output should be a time-series waveform which is mainly flat but with occasional spikes in it. I have a functor HH which works fine with a standard fixed-step Runge-Kutta routine runge_kutta4< state_type > stepper; integrate_const(stepper, HH, x, 0.0, 20.0, 0.04,trace_observer()); This code produces exactly the right waveform However, I would like to use an adaptive step size because the waveform is pretty flat between the spikes. I tried the following: integrate_adaptive(make_dense_output(1.0e-6, 1.0e-6, runge_kutta_dopri5< state_type >()), hh, x, 0.0, 10.0, 0.04, trace_observer()); This works up to about the peak of the first spike, but then crashes with the error message: Debug Assertion Failed! ... Expression: vector iterator not incrementable It dies in the Visual Studio vector library code _Vector_const_iterator& operator++() in a call from boost::norm_inf where iterator first1 reports as first1 {2.105352686232e-314#DEN} std::_Vector_const_iterator<std::_Vector_val<std::_Simple_types<double> > > I certainly don't understand how the boost code works under the hood, but I wondered if anyone could suggest a change in my calling code that might make it work? I have hand-crafted some adaptive step size code which works OK (and does run faster than the fixed step size), but it is a bit of a kludge and I would rather use code developed by people who actually understand the maths. For reasons of brevity I haven't put the HH code in this message, but could do if it would help.

[Iostreams] Known issue with 32-bit and iostreams::file_descriptor_sink?
by Tim Landscheidt 19 Feb '18

19 Feb '18

Hi, I'm trying to debug several issues in ledger (https://www.ledger-cli.org/) under Fedora 26 (boost 1.63; https://github.com/ledger/ledger/issues/534) and Debian Stretch (boost 1.62; https://github.com/ledger/ledger/issues/539) These issues occur only on 32-bit architectures (i386/i686), and on Fedora 26 (boost 1.63) some segmentation faults can be /fixed/ by executing: | std::ostream *dummy = new iostreams::stream<iostreams::file_descriptor_sink>(2, iostreams::never_close_handle); but this does not "work" on Debian Stretch (boost 1.62). Does that ring a bell for anyone? (NB: I don't want to im- ply that there is a bug in Boost, but maybe someone recog- nizes the scenario and can suggest where the real issues probably lie.) TIA, Tim

Compiling boost for Intel compiler on Windows

Hi, I followed the steps<https://software.intel.com/en-us/articles/building-boost-with-intel-c-compi…> (with adjustments for intel compiler version 18) to build boost using Intel compiler. I have Intel i7 processor, with windows 7 64-bit version, therefore I run compilervars.bat batch with intel64 flag. I run b2 with address-model=32, yet in boost libboost_log-iw-mt-gd-x32-1_66.lib is created as an x64 binary (I see it using 'dumpbin /HEADERS libboost_log-iw-mt-gd-x32-1_66.lib') I guess the library is built by default as x64 for some reason.... any idea?

by Louis Dionne via Boost 16 Feb '18

16 Feb '18

Dear Boost community, The formal review of Zach Laine's Yap library starts Monday, February 5th and ends on Wednesday, February 14th. Yap is a C++14-and-later library to build expression templates. Yap uses new features introduced in C++14/17 to make the library simpler to use and compile faster than existing solutions, such as the well known Boost.Proto library. The documentation is available here: https://tzlaine.github.io/yap/doc/html/index.html The GitHub repository is available here: https://github.com/tzlaine/yap We encourage your participation in this review. At a minimum, please state: - Whether you believe the library should be accepted into Boost - Your name - Your knowledge of the problem domain You are strongly encouraged to also provide additional information: - What is your evaluation of the library's: * Design * Implementation * Documentation * Tests * Usefulness - Did you attempt to use the library? If so: * Which compiler(s)? * What was the experience? Any problems? - How much effort did you put into your evaluation of the review? All issues discussed during this review will be tracked on the library's GitHub issue tracker at https://github.com/tzlaine/yap/issues. Regards, Louis Dionne P.S.: I've been having trouble posting to this list. If this ends up being a duplicate post, let's make this one the official one. _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost

How can I write something similar, but database iterator. I want get information from mySQL. The simplest way is add everything returning by select to vector of vector of string. But I prefer database iterator. How it write? How is in general directory_iterator as a iterator model?

I having a few problems with boost 1.53. I can build boost1.53 with, gcc 4.3-> 7.3, intel 15->17, clang 3.9.1 However with clang 5.0.1 , things go a bit pear shape. I can build boost 1.53/clang 5.0.1 and and my application no problem. However at runtime in crashes in release mode but works ok in debug mode. My early debugging point to serialisation of ptrs is broken in release mode (03) and clang 5.0.1 Has any one else seen this issue in later boost version with clang 5.0.1 ? ta, Avi

[Graph] const safety in edge_list_impl::edge_iterator
by Hormoz Zarnani 11 Feb '18

11 Feb '18

Hello, I am wondering if there is a particular reason why the == and != operators for edge_list_impl::edge_iterator (defined in boost/graph/edge_list.hpp) are not marked const: // The implementation class for edge_list. template <class G, class EdgeIter, class T, class D> class edge_list_impl { public: ... struct edge_iterator { ... bool operator==(const self& x) { return _iter == x._iter; } bool operator!=(const self& x) { return _iter != x._iter; } EdgeIter _iter; edge_id _i; }; ... }; Also, it does not seem correct to have different const qualifiers for the operands of these operators (the above effectively says that the right operand is const, but the left operand may be changed). Thanks, Hormoz

[Interprocess] Message queue hex names
by Davies, John 09 Feb '18

I have a handful of processes all communicating with message queues. Infrequently, if a process crashes and restarts, it can't connect to the previously created message queue and creates a new one with a long hex name. This is under Windows, but I'm seeing indications the same thing is happening under Linux. Or something very similar. Under what circumstances does it do this and if I can't stop it, can I at least detect that it happened? ________________________________ The information contained in this message may be confidential and legally protected under applicable law.

coroutine2: pull/push_type ctors with r-value ref arg
by MM 09 Feb '18

09 Feb '18

Hello, push_type class have this ctor: template< typename Fn > push_type( Fn && fn) that moves the object fn, leaving it in a moved-from state. I have a vector V1<C> of class C instances that expose a public member operator: void operator()( coroutine::pull_type& source ); and I would like to construct a vector V2 of push_types, of same size, each element of V2 I construct by emplacing back a element from V1. I assume that leaves the objects in vector V1 in a moved-from state and not usable. Those objects C in V1 are needed for other purposes. Can I use those instances of C by accessing them where they've been moved to inside the elements of V2? If not, should I make a copy of V1 before populating V2? Thanks,

[log] Setting log format with string
by Dirk Van Haerenborgh 07 Feb '18

07 Feb '18

Hi, I'm trying to simply set the log format of the sinks using a string. For example from a config file or just in code. Take for instance this simple line taken from the basic_example (https://github.com/boostorg/log/blob/master/example/basic_usage/ main.cpp) logging::add_console_log(std::clog, keywords::format = "%TimeStamp%: %Message%"); Whenever I add %Timestamp% to the log format, I keep getting this error: terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::gregorian::bad_year> >' what(): Year is out of valid range: 1400..10000 I can easily reproduce this by running these examples (without modification): https://github.com/boostorg/log/blob/master/example/basic_usage/ main.cpp https://github.com/boostorg/log/blob/master/example/ settings_file/main.cpp Am I doing something wrong? I have this same behaviour on both boost1.62 and boost1.65. The former as installed from the debian package manager. The latter was manually compiled... -Dirk

[intrusive] list compatibility with existing application-defined intrusive lists
by Rahul Ramadas 04 Feb '18

04 Feb '18

Hi all, boost::intrusive lists can be easily customized to be compatible with an existing doubly-linked intrusive list implementation, such as the one used in the linux kernel (struct list_head). Indeed, I have been able to declare and use a boost::intrusive::list of my own with custom traits that uses struct list_head as the underlying representation, enabling me to simply use .end().pointed_node() to get access to the list head and pass it to legacy C code that expects a struct list_head*. However, I can't think of a way to achieve interoperability in the opposite direction. For example, I have an existing function (to be precise, a callback that I pass to legacy C code), that accepts a struct list_head* that is expected to contain a list of elements of a certain type. I want some way to "wrap" this raw pointer in a type-safe intrusive list type that I use as naturally as a boost::intrusive::list (iteration, modification, etc.). I see no way to achieve this. The way I see it, what I need is a boost::intrusive::list_ptr, a container that doesn't actually own the list head, but rather, points to a list head stored elsewhere. It would have the same interface as a list, allowing me to push_back, clear, etc., but behaves as a pointer when it comes to moves and copies. Additionally, there should also be a boost::intrusive::const_list_ptr, which will not allow me to modify the list, but still allows iteration and other non-modifying operations. Unless, of course, there are already existing mechanisms to achieve this. If anyone has any ideas, please let me know. Thanks.

asio: cancelling a named pipe client
by Stian Zeljko Vrba 01 Feb '18

01 Feb '18

I have a client which connects to a named pipe as follows: CreateFile(pipeName.c_str(),GENERIC_READ | GENERIC_WRITE, 0, nullptr, OPEN_EXISTING, FILE_FLAG_OVERLAPPED, nullptr); The result of this call is assigned to a stream_handle. I want that io service shuts down orderly by run() returning due to running out of work. To achieve this, I post a lambda that effectively calls cancel() on the handle (hidden inside Kill()): _io.post([this]() { for (auto& w : _workers) w->Kill(); }); However, cancel() has no effect: the callback for async_read continues to return with error code of zero and data read from the pipe. For reference, this is the read call with its handler: template<typename T> void read(T& ioh, const asio::mutable_buffer& buf) { ioh.async_read_some(asio::buffer(buf), [this, self = shared_from_this()](const boost::system::error_code& ec, size_t sz) { if (ec == boost::system::errc::operation_canceled) return; if (ec) QUINE_THROW(Error(self->_ownersId, ec, "async_read_some")); self->ReadCompleted(sz); }); } ReadCompleted() processes the received data and loops by calling read() again. If I call close() the callback gets an error code and everything works out correctly, *except* that I get an error code [invalid handle] that gets logged as an error (though it's not). Am I correct in assuming that cancel() is an apparent noop in this case because of the race-condition where an I/O request completes successfully before cancel is invoked? If so, can you suggest a more elegant way (i.e., a way that doesn't induce a hard error) of exiting a loop as described here? Setting a member variable instead of calling cancel? Given the existence of the race-condition, what are use-cases for cancel? How to use it correctly, if at all possible? -- Stian

[boost][asio] Waiting on a returned value run in another strand
by Brian Bartman 24 Jan '18

24 Jan '18

Hello, I'm trying to preform an asynchronous operation in order to obtain a connection from a pool of available connections. I'm trying to leverage strands for two reasons, 1) I don't need locks because I can guarantee that the connection pool access is limited to quick sequential access, and 2) I may need to wait for connections to become available, or I may need to actually make a connection. I'm working with the 1.66 version of boost and I have been searching the internet for ANY answer to this question, so far none of the examples which I've located work any more. All of them simply fail to compile. For example, http://coliru.stacked-crooked.com/a/7427ec669bf0e326 This uses an older version of boost. So how can I do this under the newest version of boost.asio? Any help would be greatly appreciated. -- thanks, Brian Bartman. PhD

[test] Use-after-free with --log_sink=file, reported by gcc 7.2
by Avi Kivity 23 Jan '18

23 Jan '18

When static destructors are called, as the program exits, we destroy boost::unit_test::(anonymous namespace)::s_log_impl()::the_inst. This has a member vector, m_log_formatter_data. When destroying the second member, we run an ios_base_all_saver destructor, which attempts to restore a stream's format, however that stream has already been deallocated. Maybe that stream is in another static destructor, which was not ordered wrt. this one? Or maybe it was destroyed even earlier, when unit_test_main() exited. From ASan log, it loofs like the former. One static destructor is run from /usr/include/boost/test/impl/framework.ipp:459, while the other is run from /unit_test_log.ipp:122, so there is no ordering abong them. *** No errors detected

Build Boost 1 66
by Matt Vinson 22 Jan '18

22 Jan '18

Hello - I've been building boost with a script* (via https://studiofreya.com/2017/04/23/building-boost-1-64-with-visual-studio-2…) My Visual C++ project is a static lib so link and runtime-link are static.It's worked for several past build releases. Now with build 1_66, not all x64 libraries are built. There is 74 libraries in the win32 directory and only 27 in the x64. I locate the script using "x64 Native Tools Command Propt for VS2017" I am using Windows7. Any advice is appreciated.Matt *@echo offrem Directory to boost rootset boost_dir=boost_1_66_0 rem Number of cores to use when building boostset cores=%NUMBER_OF_PROCESSORS% rem What toolset to use when building boost. rem Visual Studio 2012 -> set msvcver=msvc-11.0rem Visual Studio 2013 -> set msvcver=msvc-12.0rem Visual Studio 2015 -> set msvcver=msvc-14.0rem Visual Studio 2017 -> set msvcver=msvc-14.1 set msvcver=msvc-14.1 rem Start building boostecho Building %boost_dir% with %cores% cores using toolset %msvcver%. cd %boost_dir%call bootstrap.bat rem Static librariesb2 -j%cores% toolset=%msvcver% address-model=64 architecture=x86 link=static threading=multi runtime-link=static --build-type=complete stage --stagedir=stage/x64 b2 -j%cores% toolset=%msvcver% address-model=32 architecture=x86 link=static threading=multi runtime-link=static --build-type=complete stage --stagedir=stage/win32 pause

Compiling Boost Libraries
by Good Guy 22 Jan '18

22 Jan '18

How do you guys compile Boost libraries in your project when all the header files are linked using angle brackets? For example in Visual Studio and C++ builder (Embarcadero) a link such as: #include <boost/config.hpp> won't compile but a link such as: #include "boost/config.hpp" Has no problems. How are we suppose to change the files so that there is no such problems. I would like to use only a few libraries in certain projects but changing the files is going to take a heck of a ling time bearing in my mind some files contains nested headers!! Am I missing something here. Surely there must a be a solution because these libraries have been going on since 1999!!

Question regarding boost binary serializer which is eating 90GB of memory, while re-reading the same content.
by dinesh kumar 21 Jan '18

21 Jan '18

Hi All, Greetings for the day. I am trying to understand the behavior of Boost's binary serializer(Boost version 1.65). Please consider the below example, where I am inserting one record into the file, and trying to read the same record 5 times. #include <boost/archive/binary_iarchive.hpp> #include <boost/archive/binary_oarchive.hpp> #include <boost/serialization/string.hpp> #include <fstream> #include <iostream> using namespace std; using namespace boost::archive; class logEntry { private: size_t m_txID; string m_jsonStr; friend class boost::serialization::access; template <typename Archive> friend void serialize( Archive &ar, logEntry &l, const unsigned int version ); public: logEntry() { m_txID = 0; m_jsonStr = ""; } logEntry( size_t id, const string &val ) { m_txID = id; m_jsonStr = val; } string getJsonValue() { return m_jsonStr; } size_t getTxId() { return m_txID; } }; template <typename Archive> void serialize( Archive &ar, logEntry &l, const unsigned int version ) { ar &l.m_txID; ar &l.m_jsonStr; } size_t prevReadPos = 0; void save( size_t n ) { ofstream file{"/tmp/test.bin", ios::binary | ios::trunc}; binary_oarchive oa{file}; // Save n records for ( int i = 0; i < n; i++ ) oa << logEntry( i, "{Some Json String}" ); file.flush(); file.close(); } // Load data batch wise void load( size_t bsize ) { ifstream file{"/tmp/test.bin", ios::binary}; binary_iarchive ia{file}; // Record file length size_t fileEnd; size_t beg = file.tellg(); file.seekg( 0, ios::end ); fileEnd = file.tellg(); file.seekg( beg, ios::beg ); logEntry l; for ( size_t i = 0; i < bsize; i++ ) { * ia >> l;* * // Reset the file read position to the beginning of the file to read the same line one more time* * file.seekg( beg, ios::beg );* } prevReadPos = file.tellg(); file.close(); } int main() { // Saving only one record save( 1 ); while ( 1 ) { // Trying to read the same record 5 times load( 5 ); sleep( 5 ); } } >From the above code, I am able to read the record one time and whenever I re-set the file pointer back to the beginning of the file, the program "Crashes with SIGKILL". And also, I observed that this process it consumed around *90GB *of memory(I got this reading from xCode while debugging the code). My dev environment is as below. clang --version Apple LLVM version 8.0.0 (clang-800.0.42.1) Target: x86_64-apple-darwin15.6.0 Thread model: posix InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin Kindly let me know if you need any more information from my side. -- Regards, Dinesh manojadinesh.blogspot.com

Google Summer of Code with Boost
by David Bellot 20 Jan '18

20 Jan '18

Hi everyone, still a few days before we submit our proposal to Google. Don't loose the chance to become a mentor for Boost. It shines on your CV, it is a great opportunity to work with brilliant students around the world, it makes you an official C++ world-wide expert. So far, we have a nice but little list of proposals here: https://github.com/boostorg/boost/wiki/Boost-Google-Summer-of-Code-2018 It would be good to have a bit more before I go and submit to Google. This will increase our chances to be selected again this year. For Boost it's a great funding worth several thousand of dollars every year. We just don't want to miss it. Best regards, David

Boost ASIO 1.66 serial port open seem to never fail opening (at least the way i'm using it)
by Mathieu Peyréga 12 Jan '18

12 Jan '18

Hello, i'm using boost asio 1.66 serial port on a Ubuntu Mate 64 machine, and I facing the fact that open("port name", error_code) command on an already openned port do not return an error. My test sequence : On the same machine I pre-open /dev/ttsS0 on minicom : minicom -D /dev/ttyS0 and check that is indeed open by sending some chars. Now while minicom still openned, I try openning a second minicom on same /dev/ttyS0 and this return an error : "device /dev/ttyS0 locked" as expected. So the device and system is able to knows that ttyS0 is already open (minicom + OS is capable of doing that) Now, with first minicom still running, if I run my program which is doing open("/dev/ttySO",ec), ec is 0 and further is-open() returns true while obviously the port is not openned. When device not already openned with minicom, my software is behaving properly. Am I doing something wrong detecting if the "open" operation suceeded ? I have a separated boost::thread io_thread(boost::bind(&C_IO_Controller::run,&theIOController)); that is running the boost::asio::io_service object the open command is called from the main thread (not the io_thread ) Regards Mathieu

Debugging into .ipp files
by Abhishek Deshpande 12 Jan '18

12 Jan '18

Hello boost users and gurus, I built boost 1.56 and client code both with -g option. When I try to debug the code, the TUI mode in GDB just wont let me navigate inside the .ipp files of boost libraries. This is a real hassle and as a work around, I generated a preprocessed output file from gcc option -E and renamed it as New.cpp file. This renamed New.cpp will have all of the template instantiations (the ones I was trying to navigate in .ipp file) of a particular boost library (e.g. serialization) embedded in it. I then compiled this New.cpp using -g and debugged it to see some miracle. But it still just doesn't navigate to places (template instantiations that are embedded inside New.cpp) . As such I am in dire need to find a way to debug these .ipp files. I hope I have made my intent clear over here. How do I debug into .ipp files using gdb ? Thanks, AD

Boost ASIO write: Socket operation on non-socket
by Sharma, Nishant 11 Jan '18

11 Jan '18

Hi, I cannot post the complete program, but when I do asio::write , I get the error: write: Socket operation on non-socket Now, just before that I check if the socket is opened or not and it indeed is opened. io_service is also running.. I just need some pointers and possible cause for this so that I can debug and take his further... My use model is I call asio::write which is synchronous and for reading I use async_read which first reads the header data and then calls asio::read to read the actual data. Best Regards, Nishant Sharma

Google Summer of Code 2018
by David Bellot 10 Jan '18

10 Jan '18

Dear Boost community, once again this year, we will apply to be a mentoring organization for the Google Summer of Code 2018. Our organization has been quite succesful for the last decade and this year we hope to be selected again. As part of filling in our application for 2018, we must supply to Google a list of potential GSoC mentors and potential GSoC projects for summer 2018 in order to be approved as an organisation this year. Therefore a lengthy page of awesome project ideas at https://svn.boost.org/trac/boost/wiki/SoC2018 before *January 23rd* would be an enormous help to getting us approved again this year and bringing to Boost another Google funding (worth dozens of thousands of dollars on average). If you think yourself able to mentor a student doing some work on Boost this summer, *please* consider adding a description of the proposed work item and your name to the list. If you want to have a better chance receiving funding for your project ideas, it is better to find good students early and that is best done by getting project ideas floated *early*. If you want to know more about mentoring a Google Summer of Code funded student work before you nominate yourself, please feel free to ask on the main Boost developers mailing list boost(a)lists.boost.org or via gsoc-admin(a)boost.org. Thank you in advance for your time. Finally, I would like to thank Niall Douglas, our previous Boost admnistrator for GSoC, who did an awesome work during many years and helped the Boost community grow thanks to all the funding we received years after years from Google. Best regards, David

1.66 changes in layout suffix seems to break cmake finder
by Stephan Menzel 09 Jan '18

09 Jan '18

Hello, I am currently trying to upgrade my projects to 1.66 and I am puzzled by a change in bjam's 'laout' parameter. I am building boost for MSVC14 (x64). Normally I use the following command line: > bjam.exe --layout=versioned variant=release address-model=64 link=static,shared runtime-link=shared threading=multi stage to achieve the build flags and setup that I need. Up until 1.65 this yielded libs named like: libboost_atomic-vc140-mt-1_65.lib This is what appears to be the most flexible for my use case and I always discover them using the 'normal' CMake finders like this: set(BOOST_ROOT ${WHERE_MY_THIRD_PARTY_STUFF_IS}/boost-1.66.0 CACHE PATH "set root of boost install") set(BOOST_INCLUDEDIR ${BOOST_ROOT}/include CACHE PATH "set boost includes") set(BOOST_LIBRARYDIR ${BOOST_ROOT}/lib CACHE PATH "set boost library dir") set(Boost_ADDITIONAL_VERSIONS "1.66.0") find_package(Boost REQUIRED COMPONENTS ...) Now over the years the meaning of the --layout parameter and its defaults have occasionally changed by I always managed to get something like this. But now, with 1.66 the filenames are changed to that: libboost_atomic-vc140-mt-x64-1_66.lib With this, CMake won't find the libs anymore. I have tried all different variantions of --layout I know (system, tagged, versioned) but I cannot get the old naming scheme back. I could rename the files manually but I am a bit afraid that this might break some linker (autolink) magick and also it doesn't seem right. Trying with several CMake finder options also got me nowhere. Using layout system is not desired as I like to quickly distinguish between versions on sight. So my question is: Is there a way to get >=1.66 to build with the filename scheme it had until now? Or is there a change to the CMake finders that will fix this? Thanks for any suggestions... Stephan

[filesystem] VS2005 compiler warnings
by Klebsch, Mario 09 Jan '18

Hi, I am using boost library 1.63.0 in an old project, which still uses VS2005. I get some compiler warnings from boost::filesystem: boost\libs\filesystem\src\unique_path.cpp(114) : warning C4267: 'argument' : conversion from 'size_t' to 'DWORD', possible loss of data boost\libs\filesystem\src\windows_file_codecvt.cpp(43) : warning C4244: 'argument' : conversion from '__w64 int' to 'int', possible loss of data boost\libs\filesystem\src\windows_file_codecvt.cpp(43) : warning C4244: 'argument' : conversion from '__w64 int' to 'int', possible loss of data boost\libs\filesystem\src\windows_file_codecvt.cpp(63) : warning C4244: 'argument' : conversion from '__w64 int' to 'int', possible loss of data boost\libs\filesystem\src\windows_file_codecvt.cpp(63) : warning C4244: 'argument' : conversion from '__w64 int' to 'int', possible loss of data boost\boost\filesystem\string_file.hpp(27) : warning C4267: 'argument' : conversion from 'size_t' to 'std::streamsize', possible loss of data boost\boost\filesystem\string_file.hpp(38) : warning C4267: 'argument' : conversion from 'size_t' to 'std::streamsize', possible loss of data I am new on boost-users, so I don't yet know, whether patches for compiler warnings are welcome, but I would like to propose some changes: For the warning in unique_path.cpp(114),I think it is safe to static_cast len to DWORD: > BOOL gen_ok = ::CryptGenRandom(handle, static_cast <DWORD>(len), static_cast<unsigned char*>(buf)); For the two lines in windows_file_codecvt.cpp, I also think that a static_cast is ok: windows_file_codecvt.cpp(42) > if ((count = ::MultiByteToWideChar(codepage, MB_PRECOMPOSED, from, windows_file_codecvt.cpp(43) > static_cast<int>(from_end - from), to, static_cast<int>(to_end - to))) == 0) windows_file_codecvt.cpp(62) > if ((count = ::WideCharToMultiByte(codepage, WC_NO_BEST_FIT_CHARS, from, windows_file_codecvt.cpp(63) > static_cast<int>(from_end - from), to, static_cast<int>(to_end - to), 0, 0)) == 0) The last two warnings are in generic parts, and changes would affect not only windows. Unfortunately, I have no good idea, on how to fix or avoid these warnings. 73, Mario -- Mario Klebsch Actia I+ME GmbH Mario.klebsch(a)ime-actia.de<mailto:Mario.klebsch@ime-actia.de> Dresdenstrasse 17/18 Fon: +49 531 38 701 716 38124 Braunschweig Fax: +49 531 38 701 88 Germany

[Boost.Asio] defer, dispatch and post differences?
by Daniel Bergström 08 Jan '18

08 Jan '18

The free functions *defer*, *dispatch* and *post* all have the exact same set of overloads and description in the library's reference (version 1.66.0). I also couldn't find anything on the subject in the *Overview* section of the library's documentation. Is the differences between them clearly described somewhere else, that I've missed, or could someone explain it? Thank you, Daniel

Boost asio reuse address
by Sharma, Nishant 07 Jan '18

07 Jan '18

Hi, Just wanted to know if setting the following option on acceptor should be ever done or not.. When should this be used.. acceptor_.set_option(boost::asio::ip::tcp::acceptor::reuse_address(true)); The reason I am asking this is because I have a server application which crashed but the socket did not close. So, the next time, I was bringing up the server, I get the error : Error occured! Error code = system:98. Message: bind: Address already in use But, even giving the option above, it is not working fine. I referred to the URL : https://stackoverflow.com/questions/34596638/boost-asio-so-reuseport to figure out the steps in which acceptor should be created from this link. Best Regards, Nishant Sharma

[process] Couple of issues
by Sebastian Messerschmidt 02 Jan '18

02 Jan '18

Hi, I'm using boost 1.64 on Windows7 with VisualStudio 2015 64bit. While testing boost.process I've encountered some issues that I'm not able to resolve: 1. Passing of multiple parameters: Consider this minimal example: <code> void test_sync() { try { bp::ipstream is; bp::child c(bp::search_path("ping"), "127.0.0.1 -t", bp::std_out > is); std::string line; while (c.running() && std::getline(is, line) && !line.empty()) { std::cerr << line << std::endl; } c.wait(); } catch (const std::exception& e) { std::cerr << "Error in execution: " << e.what(); } } </code> This doesn't correctly execute "ping 127.0.0.1 -t", instead it will act like "ping 127.0.0.1". I could not find an up2date example on how to pass parameters correctly. Any ideas? 2. No output on std::cout It seems that some applications don't output to std::cout/clog/cerr but somehow via printing to console directly (my guess as it is colored output on windows) In those instances, redirection fails. Can anyone think of a way to still monitor the output of the spawned child? Cheers Sebastian

Boost.Test: floating point comparison using absolute diference
by Georgios Sermaidis 30 Dec '17

30 Dec '17

Hi all, I am trying to find a way to make the boost unit test framework use an absolute difference for floating point comparison instead of the relative difference. I searched the documentation to try to find a suitable decorator but couldn’t find anything. Any help is much appreciated! #define BOOST_TEST_MODULE example #include <boost/test/included/unit_test.hpp> // boost::unit_test::tolerance uses relative difference and hence this test will pass; // is there anything I can use here to indicate absolute difference? BOOST_AUTO_TEST_CASE(my_test, * boost::unit_test::tolerance(0.1) ) { BOOST_TEST(10.1 == 10.3); }

[test] Set fixture for all tests
by Florian Lindner 28 Dec '17

28 Dec '17

Hello, can I set a fixture for the entire test tree, so that it is called before and after each test case? BOOST_FIXTURE_TEST_CASE does that for a test suite, but how can I apply it to all tests e.g. the master test suite? Thanks, Florian
