Redistributing Boost?
by Duane Murphy 26 Apr '02

26 Apr '02

Boost has a reasonably liberal license for use in product both commercial and non-commercial. However I am wondering about redistributing source code. Does the boost license(s?) allow the sources to be redistributed as part of a commercial product? For example, a commericial library or framework that is developed using boost for underlying support and that library is sold in source code form. What are the legalities of distributing boost in this fashion? ...Duane -- "If tyranny and oppression come to this land, it will be in the guise of fighting a foreign enemy." - James Madison

boost::thread_specific_ptr problem
by svanechel 26 Apr '02

26 Apr '02

Hi there, I've encountered a curious problem when using thread_specific_ptr. We are developing a Win32 Service and for each thread we need an object that stays alive for as long as the thread runs (except for the main thread). So we created a dll and in its DllMain function we did something like this: boost::thread_specific_ptr<SomeClass> someClass; BOOL WINAPI DllMain( HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpvReserved ) { switch ( fdwReason ) { case DLL_THREAD_ATTACH: someClass.reset( new SomeClass ); // Breakpoint 1 case DLL_THREAD_DETACH: someClass.reset(); // Breakpoint 2 } } And now comes the curious bit: If you build this dll and implicitly link it with the exe the exe's startup code hangs in GetModuleFileName (). This is the call stack upto that point _setargv (STDARGV.C) __getmainargs (CRTLIB.C) WinMainCRTStartup (CRTEXE.C) At that point the code hasn't reached Breakpoint 1 yet (it's still in the exe's startup code in the main thread and we are not interested in the main thread) It is not the class we are allocating. We tried it with an empty class and that produced the same result. However, if we stored an object in a TLS slot allocated with the API, everything works. It probably has nothing to do with the exe being a service either, since the same dll with linked to a normal exe had the same problems. To complicate matters even further we reached Breakpoint 1 in a number of runs, but as soon as we left DllMain in those instances the application hanged again. If you break then you see from the call stack that the code is running somewhere in NTDll. Are we using thread_specific_ptr in a way that it wasn't meant to be used, or did we encounter a real problem here? I've used thread_specific_ptr before and had no problems then. PS: We develop under Windows 2000 on a Compaq Evo W6000 dual processor machine, using MSVC 6, SP 5 and the 08/2001 version of the platform SDK. The service can run both under the Local System Account or under an account with absolutely no privileges at all. Sven Van Echelpoel

operator== in the shared_ptr class
by sashan 25 Apr '02

25 Apr '02

Hi Why does the operator == function in the shared_ptr class compare the pointer values and not what they are pointing to? I'm trying to use the find function (in the stl) and I don't know how to get around this. Here's an example. vector <shared_ptr <SomeClass> > vecStuff; shared_ptr<SomeClass> pkToFind(new SomeClass(x,y,z)); if (find(vecStuff.begin(), vecStuff.end(), pkToFind) != vecStuff.end()) { } This didn't work as expected because the shared_ptr class's operator== function does not use SomeClass's operator == function to do the comparison. Instead it compares the pointer values. I don't understand why they made it like this and I don't think they were dumb enough to overlook this so there must be something I'm missing. Thanks Sashan [Non-text portions of this message have been removed]

Building Boost 1.27.0 for VC7
by Javier Estrada 25 Apr '02

25 Apr '02

I'd like to build boost for VC7. I've followed several of the threads that detail some of the problems that people has faced and the solutions that have been found. Being the first time that I use boost: -How do I get access to a "free" CVS client that I can use on my machine and some information on how to use it? I'm familiar with SourceSafe on Windows platforms and I'm running Windows 2000 at home, Windows XP in my office. - Is it worth it to build 1.27, or should I wait for a "minor point" (1.27.1??) release or should I download the sources and go from there? It seems that there have been several changes made to 1.27.0 to accomodate VC7. Regards, Javier.

Boost.Threads lib files
by judoka1981 24 Apr '02

24 Apr '02

[Tried sending this through news://gmane.comp.lib.boost.user a few days ago, but it didn't seem to get through anywhere] Hi, I've started experimenting a bit with Boost.Thread, platform is currently WinXP / VC.NET. Just a question on the generated libraries and their names. Wouldn't it be more convenient to put all resulting .lib files in the same directory, and distinguishing between debug/release versions by name, e.g.: libboost_thread.lib // release libboost_thread_d.lib // debug libboost_threadmon.lib // release threadmon ... etc ... and, when the libraries support static linking of the CRT also: libboost_thread_static.lib libboost_thread_static_d.lib As it is now (Boost 1.27.0), it really is a bit awkward to use. Also, why not put all Boost library files in the same directory (e.g. BOOST_ROOT/lib) during build? Sorry if this topic already has been covered, I've been off the Boost lists for some time now. // Johan

It seems to me that we're seeing the same build problems crop up again and again. I have added a page to the Wiki: http://www.crystalclearsoftware.com/cgi-bin/boost_wiki/wiki.pl?CommonBuildPr oblems where we can build up a list of frequently-encountered problems and how to solve them. So far it's just a skeleton, feel free to add to it, everyone :-) It would be nice if we could review the email archive to add the problems to the Wiki.

RE: [Boost-Users] Linking Problem with GCC

Hi Jeff, o Platform : Win32 (WinXP/2000) o GCC -- mingw port. o Command lines for the compiler and linker, with path names removed for clarity. (Compiling a DLL) Compiling files : C:\gcc -c -DBUILDING_DLL=1 -I. "maindll.cpp" -s -mwindows -ftemplate-depth-30 -IC:\Include\ -IC:\LIBSTD~1 -LC:\Lib\ -BC:\Bin\ -Ic:\BOOST_~1 Linking files : C:\dllwrap --export-all --output-def C:\dll.def --implib "C:\libHminet~1.a" -o c:\Hminet~1.dll "c:\maindll.o" Note that when compiling an exe, the command line uses g++ for both the compile and link steps. I've attached the source for the edge connectivity example in Chapter 8.2 of the text book. The only compiler that doesn't bite it on the attached code (that I've tried) is GCC compiling as an EXE, so I'm sure my problem with compiling a DLL is environment related.

RE: [Boost-Users] Linking Problem with GCC

Hi Jeff, I agree that latest problem is possibly an STL/environment problem specifically related to linking a DLL. An exe compiles and links fine. I'm only new to GCC and am using v2.95. I tried updating to the 3.0.4 libraries but that didn't seem to help any. Anyway, I only got into this bind because VC7 and VC6 both run into Internal Compiler Errors when trying to compile (only a select part) of the BGL. I got a work around from Microsoft for one compiler bug, made a fix to the BGL code to get past another, then hit yet another internal compiler error. Where does all this happen? Specifically with examples from the BGL text book including the edge connectivity example in section 8.2. I don't blame the BGL for the bugs in the VC compilers and I guess the remainder of my woes are most likely attributable to my inexperience with the other compilers/environments. It seems, however, that for the code I am tryng to compile atleast, that there is a hurdle at every corner! I'm scared that even if I do get something going Ok, the second I use a new template I'll be in uncharted territory again. Unfortunately I can't afford this kind of risk on a fast track project. Maybe when I have more time, I'll come back to the BGL and try again. Thank you for your kind response.

Sure, I've compiled earlier versions of BGL with GCC (of course this proves little since we might have been using different parts). According to the compiler status page the graph test also works under BCC and VC6SP5. http://www.boost.org/status/cs-win32.html Which again doesn't prove much since we don't know the difference in what you are doing from the graph test does. From your previous mail the GCC problems doesn't seem to be a boost problem at all: :\data\software\code\controlled\snowbird\support\hminetworkservices\net worklib\maindll.o(.text$_S_oom_malloc__t23__malloc_alloc_template1i0Ui+0 x1a)://c/data/software/code/controlled/snowbird/support/hminetworkservic es/networklib/maindll.cpp: undefined reference to `endl(ostream &)' c:\data\software\code\controlled\snowbird\support\hminetworkservices\net worklib\maindll.o(.text$_S_oom_malloc__t23__malloc_alloc_template1i0Ui+0 x27)://c/data/software/code/controlled/snowbird/support/hminetworkservic es/networklib/maindll.cpp: undefined reference to `cerr' This looks to be an environment issue because it is complaining about not being able to find standard library components: cerr and endl.

Hi, I wanted to use the Boost Random Library with the Borland C++ 6 Compiler, unfortunately random_test.cpp fails to compile with the message [C++ Error] linear_congruential.hpp(63): E2451 Undefined symbol 'mult_add' I think its an error concerning overload resolution, but i could'nt fix it. Can someone help me? Kind Regards, Andreas Profous

hey friends i am newbie, to this. i have a project to conduct as a part of my final year projec i m stack and i think boost is the way. I am supposed to implement The Clarke and wright savings algorithms using c++ and adjacency list or matrix as a data structure. i ma having problem in this. how can i use boost to asist me with this. i have a C++ compiler how can i incoporate the c++ library with those of boost?, I will be so glad if i find somebody to assist me with details on how to go about implementinng this i will appreciate a quick response as the dead line is approaching. thanks in advance Anael --------------------------------- Do You Yahoo!?

VDB
by Martijn W. van der Lee 15 Apr '02

15 Apr '02

Hi, I've created a small framework I dubbed Virtual DataBase (VDB) which is in actuality a set of three classes which handle tables of data. table<DataT> Manages a random number of records of type DataT, including all memory management. view<DataT> Manages a sorted and/or filtered view of the records in a table. The filter and sort algorithms are supplied through functions or functors and is quite fast (though there's still room for improvement). tracker<DataT> Tracks a single record in a table. If the record is deleted, the tracker becomes invalid. That's basically it. It's built to be generic, simple and reusable. What are the chances of such a framework finding a place in the large Boost library? Currently everything seems to be working based on simple testcases but I'm still working on creating detailed testcases (using my own "Testkit" framework). regards, Martijn van der Lee

Hi again, I managed to get past the first VC7 error by adding the following line to graph/properties.hpp which appears like it was an omission... #ifdef BOOST_NO_TEMPLATE_PARTIAL_SPECIALIZATION template <> struct property_traits<default_color_type*> { typedef default_color_type value_type; typedef value_type& reference; // Newly Added typedef std::ptrdiff_t key_type; typedef lvalue_property_map_tag category; }; but now I run into yet another compiler error... \boost_1_27_0\boost\concept_check.hpp(185): fatal error C1001: INTERNAL COMPILER ERROR (compiler file 'msc1.cpp', line 1414) Please choose the Technical Support command on the Visual C++ Help menu, or open the Technical Support help file for more information template <class TT> struct DefaultConstructibleConcept { void constraints() { TT a; // require default constructor ignore_unused_variable_warning(a); } }; template <class TT> struct AssignableConcept { void constraints() { #if !defined(_ITERATOR_) // back_insert_iterator broken for VC++ STL a = a; // require assignment operator #endif const_constraints(a); } void const_constraints(const TT& b) { // C1001 INTERNAL COMPILER ERROR #if !defined(_ITERATOR_) // back_insert_iterator broken for VC++ STL a = b; // const required for argument to assignment #endif } TT a; }; Any help would be greatly appreciated...
