Using boost::function with VC6
by Edward Diener 19 Jul '02

19 Jul '02

Is there any way to use boost::function and member function pointers with VC6 . I realize it is deficient in partial specialization but I was still hoping to be able to use it. All my attempts to compile meet with failure although the compiler tests say that VC6 succeeds both with boost::function and boost::bind. If I try the bind1st.cpp example in libs\function\example directory I get the error: error C2784: 'class std::mem_fun_t<_R,_Ty> __cdecl std::mem_fun(_R (__thiscall _Ty::*)(void))' : could not deduce template argument for '<Unknown>' from 'int (__thiscall X::*)(int)' If I try some code of my own and use boost::bind instead, I get an error: error C2780: 'class boost::_bi::bind_t<R,class boost::_mfi::cmf8<R,T,B1,B2,B3,B4,B5,B6,B7,B8>,class boost::_bi::list9<class boost::_bi::value<R>,class boost::_bi ::value<R>,class boost::_bi::value<R>,class boost::_bi::value<R>,class boost::_bi::value<R>,class boost::_bi::value<R>,class boost::_bi::value<R>,class boost::_bi::value<R>,class boost::_bi::value<R> > > __cdecl boost::bind(R (__thiscall T::*)(B1,B2 ,B3,B4,B5,B6,B7,B8) const,A1,A2,A3,A4,A5,A6,A7,A8,A9)' : expects 10 arguments - 2 provided My own code is: #include "stdafx.h" #include <boost\function.hpp> #include <boost\bind.hpp> class MyClass { public: int MyMember(int,int,int); }; int MyClass::MyMember(int x,int y,int z) { int a = x + y + z; } int main(int argc, char* argv[]) { MyClass mcl; boost::function3<int,int,int,int> bf; bf = boost::bind(&MyClass::MyMember,&mcl); bf(2,3,4); return 0; }

Anyone know of any plans to push XML handling down into C++ libraries? Maybe call it the S[tandard] X[ml] L[ibrary]? ;)

Hi... Trying to use Dev-C++ with Boost. I created a new project and included all the Boost header files in the settings of the compiler. I added a new module and wrote a main() {} function after included some header files of Boost. Whe I tried to compile the program it produces an error message that the header files don't exist!!!! Can u guide me to use Boost with this compiler? Mohammed

Borland 5.5.1, STLPort, and regex
by adhalejr 18 Jul '02

18 Jul '02

A few questions about this configuration... I'm trying to compile Boost 1.28.0 using Borland C++ 5.5.1 with the STLPort 4.5.3 STL. I get the following errors on files which include the regex/config.hpp file: libs\regex\build\../src\c_regex_traits.cpp: Error E2272 D:\Tools\Boost\boost_1_28_0\boost/regex/config.hpp 538: Identifier expected Error E2272 D:\Tools\Boost\boost_1_28_0\boost/regex/config.hpp 554: Identifier expected Error E2272 D:\Tools\Boost\boost_1_28_0\boost/regex/config.hpp 578: Identifier expected Error E2272 D:\Tools\Boost\boost_1_28_0\boost/regex/config.hpp 579: Identifier expected Error E2272 D:\Tools\Boost\boost_1_28_0\boost/regex/config.hpp 580: Identifier expected Error E2272 D:\Tools\Boost\boost_1_28_0\boost/regex/config.hpp 581: Identifier expected Error E2272 D:\Tools\Boost\boost_1_28_0\boost/regex/config.hpp 582: Identifier expected Error E2272 D:\Tools\Boost\boost_1_28_0\boost/regex/config.hpp 583: Identifier expected I believe this all has to do with the various C standard library symbols (e.g. fseek) not being "known" when placed in the using ::<symbol> construct. I've wandered through the various config.hpp files, the stuff for platform, compiler, and stdlib, etc. It would seem that the right set of stuff is being picked but there's some unexpected behavior being encountered when #include-ing standard headers from STLPort via Borland. Any ideas on correcting this? Other, somewhat related, questions: If I build w/o STLPort, things seem OK. The regex static libraries are placed in a "runtime-link-dynamic" directory. Threads, on the other hand, has that directory as well as a "runtime-link-static" directory variation. Does the directory name imply which version of the compiler's RTL is required when linking w/ that version of the Boost library? And is there a reason that regex didn't have a "runtime-link-static" directory and associated static library created? I want to statically link the RTL and boost w/ my app. Finally, how do I go about creating just a single boost library (so I can try building threads w/ STLPort w/o encountering the regex errors). Many thanks, Donnie

Compiling a threads DLL using VC6
by sdussin 17 Jul '02

17 Jul '02

I just downloaded Boost and am trying to do some development using it. Our product will be developed and fielded on both Win2K and Solaris. So far I've been using Boost solely on VC6, and I have a question regarding building the threads library. I've gotten the build to run correctly, but it doesn't seem to build a DLL version of the library. I looked in the both the runtime-link-static and runtime-link-dynamic dirs, and both contain only a .LIB version of the library. Is there something I'm doing wrong here? Or am I misunderstanding what should be generated? Any clarification or pointers would be greatly welcomed. Thanx, Steve Dussinger
