Conflict beetween stdcxx and visual hash_map implementation at compilation

[Nadine Faizant <na...@nautitia.fr>]

    Hello,

    I finally understand that hash_map is not part of STL :-(   I found the stdext::hash_map from VC compilator extension. While I'm compiling my code using strdcxx STL I have got compilation error under Visual 8


Here is my c++ source.

#include <hash_map>

#include <tchar.h>

int _tmain(int argc, _TCHAR* argv[])

{

typedef stdext::hash_map<int, std::string, std::string, std::string> tutu;

return 0;

}

Output command:

see attach ziped file

Compilation command :

/Od /I "D:\NPTE\dev\src\cpp\externals\win32\include" /I "D:\NPTE\dev\src\cpp\externals\win32\include\ansi" /I "D:\NPTE\dev\src\cpp\externals\win32\include\15d" /D "WIN32" /D "_DEBUG" /D "_CONSOLE" /D "_RWSTD_USE_CONFIG" /D "_RWSHARED" /D "_RWSTDDEBUG" /D "_UNICODE" /D "UNICODE" /Gm /EHsc /RTC1 /MDd /Fo"Debug\\" /Fd"Debug\vc80.pdb" /W3 /nologo /c /Wp64 /ZI /TP /errorReport:prompt

If i do not use stdcxx (no include file and preprocessor flags), there is no error. I have tried a make -E, but I don't understand what happens (attach ziped  file).

Any help appreciated,

    Thanks,

    Nadine

You can't mix stdcxx or any other third party implementation with
the native C++ standard library. All headers must come from the
same implementation of the C++ standard library, and so must all
the libraries you link with. It's quite likely that VC++ hash_map
makes assumptions about some other components of the library that
don't hold for the third party implementation.

 From the make-E.txt file it's clear that you are mixing VC++ headers
with those of stdcxx in the same translation unit. That's wrong. You
need to pick one implementation and stick with it.
