You are using the debug DLL version of the date_time library. In order to share a heap with the main program this uses the debug DLL version of the C++ run-time library (MSVCRTD) and requires that the main program uses it too. You must either: (1) Build and use the debug multi-threaded static version of the date_time library. (2) Use the debug DLL versions of the C++ run-time library and MFC in your main program.

Building 1.31.0 with intel-linux for Itanium 2
by Richard Hadsell 10 May '04

10 May '04

I am trying to build the Boost libraries on an Itanium 2 Linux machine using Intel C++ 8.0. The problem is that bjam is creating a directory path for the release versions that uses the string "ebug release" instead of "release". For example: MkDir1 bin/boost/libs/regex/build/libboost_regex.a/intel-linux/ebug release intel-linux-C++-action bin/boost/libs/regex/build/libboost_regex.a/intel-linux/ebug release/c_regex_traits.o ... Despite the directory that it creates with an embedded space, everything actually continues quite well, until it tries to run ranlib: intel-linux-Archive-action bin/boost/libs/regex/build/libboost_regex.a/intel-linux/ebug release/libboost_regex-il-1_31.a Ranlib bin/boost/libs/regex/build/libboost_regex.a/intel-linux/ebug release/libboost_regex-il-1_31.a ranlib: bin/boost/libs/regex/build/libboost_regex.a/intel-linux/ebug: No such file or directory ranlib bin/boost/libs/regex/build/libboost_regex.a/intel-linux/ebug release/libboost_regex-il-1_31.a ...failed Ranlib bin/boost/libs/regex/build/libboost_regex.a/intel-linux/ebug release/libboost_regex-il-1_31.a... I built bjam with this: build.sh intel-linux And I built the libraries with this: bjam -sTOOLS=intel-linux -sINTEL_PATH=/usr/local/intel/compiler80/ia64 --with-python-root=/usr --stagedir=stage -sBUILD="debug release <threading>single" stage Can anyone suggest what might be wrong with my system? It is a loaner, so everything is untested as far as I'm concerned. I have no idea what other tools in addition to Bjam itself might be involved in causing this problem. -- Dick Hadsell 914-259-6320 Fax: 914-259-6499 Reply-to: hadsell(a)blueskystudios.com Blue Sky Studios http://www.blueskystudios.com 44 South Broadway, White Plains, NY 10601

RE: [Boost-users] Re: shared_ptrs with std::mem_fn

> boost::mem_fn erases the need for a separate mem_fn_ref. If > http://www.boost.org/libs/bind/mem_fn.html fails to explain it to you, > please ask more specific questions. I thought I'd been pretty specific... guess not. Allow me to reiterate: Why doesn't std::mem_fun work with a container of boost::shared_ptr? I fiddled around with my compiler for a while (vc6), but ended up with a wildly unhelpful error message. Given the following lines of code (among others): --- typedef std::vector<boost::shared_ptr<std::string> > Strings; Strings strings; std::for_each( strings.begin(), strings.end(), std::mem_fun(std::string::size) ); --- my compiler puked up the following wildly useless error message: --- error C2664: 'mem_fun' : cannot convert parameter 1 from 'unsigned int (__thiscall std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >::*' to 'unsigned int (__thisca ll std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >::*' Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast --- Allow me to pull out those two types for easier viewing: unsigned int (__thiscall std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >::* unsigned int (__thiscall std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >::* Golly. Those 'two' types are about as related as you can get. So why won't std::mem_fun work through boost::shared_ptr's operator->? Here's the mem_fun that ships with VC6: --- template<class _R, class _Ty> class mem_fun_t : public unary_function<_Ty *, _R> { public: explicit mem_fun_t(_R (_Ty::*_Pm)()) : _Ptr(_Pm) {} _R operator()(_Ty *_P) const {return ((_P->*_Ptr)()); } private: _R (_Ty::*_Ptr)(); }; --- The relevant portion to our discussion is: "{return ((_P->*_Ptr()); }" which can be further boiled down to: return _P->_Ptr(); This looks an awful lot like it should work with a shared_ptr's operator->(). So why doesn't it? I admit that this is more of a C++ question than a boost one, but it's not too much of a tangent and I *am* curious. Mentioning mem_fun_ref in my previous post only served to muddy the waters. My apologies. --Mark Storer Senior Software Engineer Verity, Inc.

shared_ptrs with std::mem_fn
by Steve Folly 07 May '04

07 May '04

Hi, I've converted a container to use shared_ptrs instead of regular pointers, now my for_each algorithm doesn't work: Before: class Attr; std::vector< Attr* > mAttributes; . . . std::for_each( mAttributes.begin(), mAttributes.end(), std::bind2nd( std::mem_fn( &Attr::Write ), output ) ); After: std::vector< shared_ptr<Attr> > mAttributes; Now it doesn't compile because (of course) Attr::Write is not a method of shared_ptr<Attr>. Do I have to use boost's bind and mem_fn objects instead of std? Thanks for any help. -- Regards, Steve.

Why is this a problem? I thought std::mem_fn called the function through the -> operator, which 'should' work (but obviously doesn't). I would think this would only crop up through mem_fun_ref, but then you wouldn't have a container of shared_ptr<Attr>, but Attr. --Baffled --Mark Storer Senior Software Engineer Verity, Inc.

date_time clocks, microsec_clock, etc
by Aaron W. LaFramboise 07 May '04

07 May '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I'm a little curious whats in the works for date_time clock support. Specifically, there still doesn't seem to be anything better than a second-granularity clock for Win32. In addition, the UNIX clock is not always as precise as it could be. In particular, the popular Pentium and and some other architectures have some sorts of cycle-granularity hardware clock or similar that can exceed the usual operating system clock used for time. Really--and I have no idea what work is presently being done on this--it might do people in some problem domains (including myself, at times) a lot of good to have clocks with separate notions of precision and accuracy. For example, on a Pentium, operating systems I care about tend to have a maximum system clock accuracy around about a millisecond plus or minus some, and its probably difficult or tricky to get better than that. However, if the system clock was used in combination with the Pentium cycle counter, we could probably get precision in excess of a nanosecond. Perhaps an interface for such a clock system might be: typedef boost::date_time::clock<type_of_accuracy_you_need_here, type_of_precision_you_need_here> myclock; To get the above imagined clock, I might use: clock<microsecond_accuracy, cycle_precision> If the clock requested was unavailable on the platform, a compile time error might result. Of course, oftentimes we know the characteristics of a clock's accuracy or precision, such as the Pentium cycle counter, but we don't know exactly how precise it is, so it might be inappropriate to refer to that clock as nanosecond_precision when it really might not be. In summary, a reliable cross-platform sub second clock is one of the features I miss most in date_time, and one of the features I can afford to miss least. Is anyone working on remedying this right now? Aaron W.

Using pool_alloc with std::map
by Kevin Lin 06 May '04

06 May '04

I am using boost::pool_alloc with std::map like this: typedef map<int, int, less<int>, pool_alloc<pair<int, int> > > MapT; MapT myMap; After myMap passes out of scope, I want to release unused memory from the pool. To do that, I need to get the type used to request chunks from the pool. pair<int, int> is not the answer since map uses rebind to get a different allocator. So how do I go about obtaining the correct singleton_pool interface? Your help is appreciated. -- Kevin Lin

Question about compiling boost.1.31.0 on Solaris
by Wenning Qiu 06 May '04

06 May '04

I was trying to build the regex library from boost.1.31.0 on a Solaris 7 box using STLport.4.6.2. I have a couple of STLport versions installed in /opt. Here's how I built: o cd boost_1_31_0/libs/regex/build o /export/home/qiuw01/research/boost-jam-3.1.9/bin.solaris/bjam "-sTOOLS=sunpro-stlport" -sSTLPORT_PATH=/opt I was expecting STLport.4.6.2 to be used. However when I used ldd on the generated .so library, it shows a dependency on an old version of STLport in /usr/lib qiuw01$ ldd libboost_regex-sw-p-1_31.so librt.so.1 => /usr/lib/librt.so.1 libstlport_sunpro.so.4.5 => /usr/lib/libstlport_sunpro.so.4.5 libaio.so.1 => /usr/lib/libaio.so.1 libc.so.1 => /usr/lib/libc.so.1 libdl.so.1 => /usr/lib/libdl.so.1 /usr/platform/SUNW,Ultra-4/lib/libc_psr.so.1 <ethos:~/research/boost_1_31_0/bin/boost/libs/regex/build/libboost_regex.so/ sunpro-stlport/release> This doesn't seem to be right. Any comments? Thanks, Wenning Qiu

boost::any and arithmetic ?
by Mailing List 06 May '04

06 May '04

Greetings all, as I'm new to this list, I'll keep my query short. It was suggested to me to use boost::any to store numeric values of whatever type (int, float, double, etc) so that I could use one std::list to store multiple values. I've looked through the header (any.hpp) and I admit it's a little hard for me to follow. I'm not what you'd call a superprogrammer... yet. :) I understand how to store a value in the boost::any object, but I'm not clear on how one would get that value back later (for display on screen, etc). What I'd really like to do is similar to one of the examples: --- snip --- struct property { property(); property(const std::string &, const boost::any &); std::string name; boost::any value; }; typedef std::list<property> properties; --- snip --- But I want to be able to do arithmetic with the resultant object(s): property T; property V; property Z; T [+-*/] Z; T = V [+-*/] Z T + [int,float,etc]; And so on. However, I want to make sure that the normal arithmetic type conversions (type promotions) take place (i.e. int + float returns a temporary object of type float). Example: boost::any value1; boost::any value2; boost::any value3; value1 = 127.915; value2 = 17; value3 = value1.getwhatevervalue() + value2.getwhatevervalue(); cout << value3.getwhatevervalue() << endl; value3 = value2.getwhatevervalue() + value1.getwhatevervalue(); cout << value3.getwhatevervalue() << endl; Both should return a temporary float with a value of 144.915. since I don't know how to get the value from boost::any, I just used getwhatevervalue() as an example. Sincerely, GRE

Posix extended regexp

Hello, I'm new to boost and I had one question. I'm trying to match strings against regular expressions that are expected to be posix extended regular expressions. But for some reason, the modifier ^ doesn't seem to be working. For example, when I try to match "Manish" against "^[mM]anish.*", I am returned false. What am I doing wrong? Here's my short matching function: bool MatchRegExp(const std::string& matchThis, const std::string& againstThis) { try { const boost::regex e(againstThis);//, boost::regex_constants::icase); return boost::regex_match(matchThis, e, boost::regex_constants::extended); } catch(boost::bad_expression be) { return false; } } thanks Manish

Boost license and Open Source
by eze.boost.org.users＠secureit.mailshell.com 04 May '04

04 May '04

Hi. I'm thinking of starting an open source project, and I'm seriously considering using Boost. I've read many messages regarding the practical aspects of using boost with other projects (particularly open source). However, I have found nothing useful regarding the legal aspect of using Boost for an open source project. As I'm considering licensing my project under the GPL, I'm concerned about the GPL "friendlyness" towards Boost. Besides the technical aspect of it, what is the best way to structure the project, to license the project, etc. in order to satisfy GPL and Boost licenses? Any help would be much appreciated. Best regards, Ezequiel "This communication is intended solely for the addressee and is confidential and not for third party unauthorised distribution."

hi! the following pattern (35 matching token, and at least one more) with this simple expression ("[_]+$") throws "memory exhausted" when using wchar_t strings. the same works with char strings even triple sized. matching doesnt throw, if we use "^[_]+$", "[_]{1,}$", "[_][_]*$" etc. so this is a bug. it seems the expression-string is short enough to cause some problem, but i was unable to track down the error. wchar_t * wp = L"___________________________________x"; wregex wre(L"[_]+$"); try { regex_search(wp, wre); } catch (bad_expression & e) { cout << e.what() << endl; } another issue: i think, "(one|two|three|)" style alternation (notice the empty string on the right) should be accepted and handled as "(one|two|three)?" now it throws bad_expression

Problem 2 with Boost 1.31.0 Regex for tru64cxx65

Having persuaded everything to compile in the 1.31.0 Regex library, it runs into another problem in building the .a archive libraries: tru64cxx65-Archive-action bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/libboost_regex-tru-1_31.a /bin/sh: /bin/ar: arg list too long rm -f bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/libboost_regex-tru-1_31.a ar r bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/libboost_regex-tru-1_31.a bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/c_regex_traits.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/c_regex_traits_common.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/cpp_regex_traits.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/cregex.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/fileiter.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/posix_api.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/regex.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/regex_debug.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/regex_synch.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/w32_regex_traits.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/wide_posix_api.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/instances.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/winstances.o "bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release"/cxx_repository/* ...failed tru64cxx65-Archive-action bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/libboost_regex-tru-1_31.a... The problem is due to the number of instantiations in the template repository and the lengths of their names. There are 492 instantiations, and many of them have 90-character file names, which looks like the compiler's maximum allowed. I solved the problem in previous versions of boost by breaking up the build into separate steps. This was the way I modified the make file: AR:= ar -cq IIDIR:= $(LIBDIR)/cxx_repository $(DIRNAME)/lib$(LIBNAME).a : $(ALL_O) @echo "*** creating lib$(LIBNAME).a" rm -f $@ $(AR) $@ $^ @echo "*** adding template instantiations" $(AR) $@ $(IIDIR)/[_A-Z]* $(AR) $@ $(IIDIR)/[a-z]* It builds the library from just the object files and then adds the instantiations in two steps. (Apparently, adding all of them exceeded the same shell arg list limit.) How can I do something equivalent with bjam to build the library? -- Dick Hadsell 914-259-6320 Fax: 914-259-6499 Reply-to: hadsell(a)blueskystudios.com Blue Sky Studios http://www.blueskystudios.com 44 South Broadway, White Plains, NY 10601

regex patches available
by John Maddock 03 May '04

03 May '04

All users of Boost.Regex-1.31.1 should be aware that there are now a set of patches available for this release - see https://sourceforge.net/project/showfiles.php?group_id=7586 for downloads. Issues fixed include: POSIX style regular expressions not behaving correctly with regex_grep. Non-greedy repeats not backtracking correctly in some cases. Backreferences cause some repeat operators to behave incorrectly. Some wide character expressions weren't getting correctly optimised, leading to thrown exceptions in trivial cases. Misc. compiler compatibility fixes. Regards, John Maddock

Problem building Boost 1.31.0 for VC6
by Estese 02 May '04

02 May '04

Hi, I'm trying to build the Boost 1.31.0 libraries for VC6 (on WinXP). My installation of MSVC is "C:\Program Files\Microsoft Visual Studio\VC98". All my user environment variables point to this location, as they should. I created the bjam executable, placed it in my Boost root (C:/boost_1_31_0), and then ran bjam with the following command: bjam "-sTools=msvc" However, it attempts to run the following command for every library: "CALL D:\Program Files\Microsoft Visual Studio .NET 2003\VC7\bin\cl" I don't even have .NET installed on my PC! Why would it be doing this? I tried explicitly telling bjam where vc6 is with the -sMSVC_ROOT argument, but it always outputs the same result. I've verified all my user environment variables, and they all point to C: and to VC6, as they should. I don't know why bjam insists on trying to build the boost libraries for Visual Studio .NET. Any thoughts? Sean Estey __________________________________ Do you Yahoo!? Win a $20,000 Career Makeover at Yahoo! HotJobs http://hotjobs.sweepstakes.yahoo.com/careermakeover

serialization library
by Russell Balest 01 May '04

01 May '04

Robert, Thank you for writing the serialization library. I'm in awe that someone finally did this so well. I've been using it for 2 days and think it's fantastic. I've been mucking with serialization frameworks myself for 8 years; now this will trump all my efforts and I'll give up and switch. Many Thanks, Russell Balest

lexical_cast<string> of type char
by DY, JERRY U (SBCSI) 01 May '04

01 May '04

I'm converting our code to use lexical_cast for converting between our numeric types to string. It worked mostly but was surprised to see what looked like graphic characters on my screen. It turns out that when we wanted to display the ascii value of a character, lexical_cast<string> doesn't work -- it doesn't treat the char as a numeric, which when we really think about it, makes a lot of sense. Casting the char to int solves the problem. But I was just wondering how the experts would handle this. char c = 65; string s1 = lexical_cast<string>(c) // s1 = "A" string s2 = lexical_cast<string>((int)c) // s2 = "65" Thanks! -Jerry

Hi, I'm using Boost 1.31.0 with VC++ 7.1 and I'm having some problems converting std::string to std::wstring and back.

This is not brain-dead. It is useful to be able to control the order in which symbols are looked for since they may be defined in more than one library. It is a bit weird that -l is not placed before the file names as is the Unix convention for options, but it *isn't* an option - it is a shortcut for specifying a file in the library search path that follows the usual library name convention (lib<name>.a) and is exactly equivalent to specifying the full file name (AFAIK). Secondly, there is no g++ linker. g++ can use various Unix linkers though it is most commonly used together with the linker from GNU binutils. However, all Unix linkers should behave this way. Ben.

Config question: BOOST_NO_INTRINSIC_WCHAR_T (Intel 7.1)
by Christopher D. Russell 30 Apr '04

30 Apr '04

Hello folks, I'm just getting around to upgrade to Boost 1_31_0 from Boost 1_30_0. I'm attempting to use 1_31_0 out-of-the-box (w/no bjam) but am confused about how to resolve problems related to native wchar_t support (or lack thereof). Some details: I'm using MSV6 with the Intel 7.1 compiler. Specifically I'm using: Intel(R) C++ Compiler for 32-bit applications, Version 7.1 Build 20030609Z I added a few #pragma messages to the config headers and have verified that config indeed seems to making the right decisions - at least at a high level: [Boost Configure: Selected Intel Compiler] [Boost Configure: Selected STLport Standard Library] [Boost Configure: Selected Win32 Platform] The specific error I encounter: d:\ENCAPSULE-EXTLIB\boost\boost_1_31_0\boost_1_31_0\boost/type_traits/is_inte gral.hpp(38): error: class "boost::is_integral<unsigned short>" has already been defined BOOST_TT_AUX_BOOL_TRAIT_CV_SPEC1(is_integral,wchar_t,true) ^ d:\ENCAPSULE-EXTLIB\boost\boost_1_31_0\boost_1_31_0\boost/type_traits/is_inte gral.hpp(38): error: class "boost::is_integral<const unsigned short>" has already been defined BOOST_TT_AUX_BOOL_TRAIT_CV_SPEC1(is_integral,wchar_t,true) ^ d:\ENCAPSULE-EXTLIB\boost\boost_1_31_0\boost_1_31_0\boost/type_traits/is_inte gral.hpp(38): error: class "boost::is_integral<volatile unsigned short>" has already been defined BOOST_TT_AUX_BOOL_TRAIT_CV_SPEC1(is_integral,wchar_t,true) ^ d:\ENCAPSULE-EXTLIB\boost\boost_1_31_0\boost_1_31_0\boost/type_traits/is_inte gral.hpp(38): error: class "boost::is_integral<const volatile unsigned short>" has already been defined BOOST_TT_AUX_BOOL_TRAIT_CV_SPEC1(is_integral,wchar_t,true) ^ ... tracked back into .../1_31_0/boost/type_traits/is_integral.hpp #ifndef BOOST_NO_INTRINSIC_WCHAR_T BOOST_TT_AUX_BOOL_TRAIT_CV_SPEC1(is_integral,wchar_t,true) #endif ... where BOOST_NO_INTRINSIC_WCHAR_T is defined in ../1_31_0/boost/config/compiler/intel.hpp // See http://aspn.activestate.com/ASPN/Mail/Message/boost/1614864 #if BOOST_INTEL_CXX_VERSION < 700 # define BOOST_NO_INTRINSIC_WCHAR_T #else // _WCHAR_T_DEFINED is the Win32 spelling // _WCHAR_T is the Linux spelling # if !defined(_WCHAR_T_DEFINED) && !defined(_WCHAR_T) # define BOOST_NO_INTRINSIC_WCHAR_T # endif #endif I read the post on ActiveState but I'm still confused. With the frequency of Intel compiler updates is it possible this particular release is not setting the expected macros correctly? If someone could give me a kick in the right direction I would appreciate it. I really want to try some of these nifty Spirit v1.8 facilities (wow Joel). - Thanks Chris

Problem with Boost 1.31.0 Regex for tru64cxx65
by Richard Hadsell 29 Apr '04

29 Apr '04

Having found out how to build Bjam, I have tried to build the libraries of Boost 1.31.0 for tru64cxx65. I'm only interested in Regex at the moment, so I won't bother you with the problems building other libraries. When the build gets to this point: tru64cxx65-C++-action bin/boost/libs/regex/build/libboost_regex.so/tru64cxx65/release/cregex.o it hangs. I have run into this situation with other large files, and my usual remedy is to decrease the optimization level. How can I do that? If I can't do it for just this file, I'm willing to reduce the optimization level for the entire library, or even for all libraries. (This is not a platform that I worry about performance; it's just there to support a few vestigial machines.) -- Dick Hadsell 914-259-6320 Fax: 914-259-6499 Reply-to: hadsell(a)blueskystudios.com Blue Sky Studios http://www.blueskystudios.com 44 South Broadway, White Plains, NY 10601

Problem building archive libs for mipspro
by Richard Hadsell 28 Apr '04

28 Apr '04

I am trying to upgrade from Boost 1.30.0 to 1.31.0. My main interest is in the Regex library. I was pleased to build its libraries successfully for intel-linux, both .a and .so forms, using bjam. When trying to build the libraries for mipspro, it fails to build the .a forms, because it is trying to use ranlib. The bjam system is too unfamiliar to me to debug it, so I'm hoping somebody else can give me a remedy. (Note: I built bjam from the source in tools/build/jam_src, as described in the docs.)

Iterators
by Witz 24 Apr '04

24 Apr '04

just a quick question - which maybe should have been directed at the developers list but ... would it be possible in the iterator adaptors to have an operator== defined that takes the base iterator as the right hand side? it would certainly cut down on typing and also obviate the need to create an end iterator that is only used as an 'end of container' sentinel value if it was possible it would allow us to write, for example: copy( make_filter_iterator<is_positive_number>(numbers, numbers + N), numbers + N, ostream_iterator<int>(cout, " ")); rather than: copy( make_filter_iterator<is_positive_number>(numbers, numbers + N), make_filter_iterator<is_positive_number>(numbers + N, numbers + N), ostream_iterator<int>(cout, " ")); of course i am aware that i might be missing something obvious ... ian whittley

boost format problems
by Navneet Dalal 23 Apr '04

23 Apr '04

Hi I decided to try boost::format for more compact and typesafe formatting of text. However, I am running into some problems. Problem 1 ============== The following line throws boost:bad_format_string exception. std::cout << format("%|1| %|2$3|") % "Hello" % 3 << std::endl; However, this one works std::cout << format("%|1|") % "Hello" << std::endl; All I want to do is use notation for printing character streams i.e. %|1| instead of %1% Is this a bug or I am doing something wrong? Problem 2 ============= How can I print a float such that it appends 0 for remaining precision digits. For e.g. let us say I want to print 0.2 with 5 characters of overall length and till 3 digits of precision. Kind of output I am looking for is 0.200 One would expect that following command may work (as I am indicating left print, fill any remaining characters and till 3 digits of precision after decimal) std::cout << format("#%|1$-05.03|#") % 0.2 << std::endl; // however it prints #0.2 # This command prints something like std::cout << format("#%|1$05.03|#") % 0.2 << std::endl; // it prints #000.2# with C++ cout, I can print it like std::cout << '#' << std::left << std::setfill('0') << std::setw(5) << std::setprecision(3) << 0.2 << '#' << std::endl; so on similar lines I wrote following line. it works, but it seems ugly to use group only for this std::cout << format("#%|1$-05.3|#") % group(setfill('0'), 0.2) << std::endl; // prints #0.200# Does any one has any other suggestions? regards navneet

Compilation problem with BOOST::filesystem lib
by Peter Koerber 23 Apr '04

23 Apr '04

Hello, i try to compile the *.cpp files of boost::filesystem within the following environment: os: Windows XP compiler: Visual C++ Toolkit 2003 (this is the free version of MS Visual C++ V7.1) boost: Version 1.31.0 If BOOST_WINDOWS is defined, the file windows.h is included in the sources: * exception.cpp * operations_posix_windows.cpp. Otherwise the file errno.h is included. BOOST_WINDOWS is defined within the environment mentioned above, but the compiler does not have a windows.h include file. Hence compilation fails. OTOH, if BOOST_WINDOWS is "manually" undefined, the errno constant: ETXTBSY is not defined in the file errno.h which comes with the Visual C++ Toolkit 2003. Kind regards Peter

BGL: INTERNAL COMPILER ERROR in VC7.1
by Nicholas Burlett 22 Apr '04

22 Apr '04

I'm rather unsure about what is causing this, but I get an internal compiler error in Visual C++ 7.1 when using BGL in some specific circumstances. I have a graph defined in class Graph defined as such: typedef property<edge_feedback_t, bool> EdgeFeedback; typedef property<edge_sourcejack_t, IAudioOutputJack*, EdgeFeedback> EdgeSourceJack; typedef property<edge_destinationjack_t, IAudioInputJack*, EdgeSourceJack> EdgeDestinationJack; typedef EdgeDestinationJack EdgeProperty; typedef boost::property<boost::vertex_index_t, int> VertexIndexProp; typedef property<vertex_name_t, nsCOMPtr<IAudioModule>, VertexIndexProp> VertexProperty; typedef adjacency_list<listS, listS, bidirectionalS, VertexProperty, EdgeProperty> graphdata; typedef graph_traits < graphdata >::vertex_descriptor vertdsc; This definition works fine in the graph.cpp file that implements the class Graph. However, when I use graph.h in another cpp file, I get bizarre compiler errors: c:\Boost\include\boost -1_31\boost\mpl\aux_\preprocessed\plain\apply.hpp(50) : fatal error C1001: INTERNAL COMPILER ERROR After some trial and error, I narrowed the problem down to needing to have a != between two oedge_iterators _somewhere_ in the cpp file including graph.h. Simply putting the following function into my other files will cause them to compile just fine: void makeVChappy() { typedef graph_traits< Graph::graphdata >::out_edge_iterator oedge_iterator; oedge_iterator oiter, oend; oiter != oend; } I'm a a complete loss as to how this could be happening, but since I have a work-around for now, I'm not going to push the issue too much further at the moment --- I just thought I'd bring this to your attention, and see if anyone knows of a more elegant solution.

Problems with installation of boost unit_test_framework
by Matthew Burgess 21 Apr '04

21 Apr '04

Hi folks, http://www.boost.org/libs/test/doc/components/unit_test_framework/compilati… states that I can include <boost/test/included/unit_test_framework.hpp> in order to avoid having to link against the unit_test_framework library. However, the files it #includes are located in the boost test library source directory which doesn't appear to be installed by the default bjam procedure (I just get '/opt/boost/lib' &'/opt/boost/include' directories after installing boost). If it helps to clarify things here's some output: --- bash-2.05b$ cat example1.cpp #include <boost/test/included/unit_test_framework.hpp> using boost::unit_test_framework::test_suite; void test_function() { BOOST_CHECK(2 == 1); // intentional failure } test_suite* init_unit_test_suite(int, char* []) { test_suite* test = BOOST_TEST_SUITE("Unit test example 1"); test->add(BOOST_TEST_CASE(&test_function)); return test; } bash-2.05b$ g++ -I /opt/boost/include/boost-1_31/ -L /opt/boost/lib/ -o test example1.cpp In file included from example1.cpp:2: /opt/boost/include/boost-1_31/boost/test/included/unit_test_framework.h pp:18:47: libs/test/src/execution_monitor.cpp: No such file or directory ... --- The only place I find the required files is in the original location I extracted the boost source tarball to. I can (and have) copied the 'libs' directory to sit inside my 'include' directory and verified this fixes things, but I doubt very much this is the correct solution. I'm particularly concerned that if someone else wants to compile my toy code, simply telling them to "install boost" might not be enough. Related to all this is the issue of best-practice. Should I make efforts not to have to link to a library, what are the trade-offs? Can I simply take a copy of the required boost headers and place them directly in my project's directory structure? If not, is anyone aware of an autoconf style macro that can be used to detect the presence of the boost headers and/or libraries? I took a quick glance at the autoconf-archive but didn't see anything immediately. Thanks for anyone who can hit me with a cluebat (or FAQ pointer). Matt Burgess

The match-flags area distinct type, so use: boost::match_flag_type flags = boost::match_default; John. _______________________________________________ Boost-users mailing list Boost-users(a)lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users

Selection scheme for boost libraries
by Uli Tuerk 19 Apr '04

Hi all! I have a very basic problem with the boost libraries: I used bjam to build all boost libraries for Linux (using "gcc" as toolset and the call 'bjam "-sTOOLS=gcc" install'). All went fine, however I wanted to do the regression tests for boost_regex using the gcc.mak Makefile in <boost_main>/libs/regex/test/regress which uses "-lboost_regex" for linking. The linker reported an error because there is no "libboost_regex.so" in my lib folder unless I created a link with this name to one of the various versions of libboost_regex. A comment for these Makefiles would be helpful for the case when having build all with bjam. When compiling the regex part alone, the library is created in build/gcc with the correct name (libboost_regex.so). I'm new to C++, so maybe I haven't got the point with the sophisticated naming scheme of the libraries, but: for the library "libboost_regex-gcc-mt-d-1_31.so" e.g. are the tool specifier ("gcc") and the version ("1_31") really necessary for a platform using version numbering of the libraries anyway in the ".so" extension? OK, there are still the categories with/without debug and with/without threading. How would you guys select the type of library? In the Makefile? Thanks in advance!
