Bcp.exe won't compile

[seppi2112@…]

Compiling the boost_1_38_0 package in VC9 with Python 2.6. Everything works fine until the compiler gets to the BCP project and I get 10 linking errors. I'm completely new to Boost so the problem is probably on my end, but I have no idea how to resolve this. Any ideas?

Error message follows:

I have no idea where the project files that you are using come from, but you probably need to remove the boost_regex library from the linker and let automatic linking work.

[Seppi2112@…]

I tried adding /force:multiple to the command line and the redefined error changed to "Cannot open include file: 'boost/shared_ptr.hpp' and 'boost/regex.hpp'." Grr. I'm going to just clean this whole project and try and CMAKE it again... maybe I had a library setting wrong.

[Steven Watanabe]

Ah. The Cmake build is fairly new and not officially supported.

[Seppi2112@…]

That makes sense then. I'm trying to build boost for use in Delta3D and they recommend using CMake... is there a better suggestion?

I have the same problem in VC8 (python 2.5.4), CMake 2.6-p2. The project files are somehow wrong, booth debug and release libraries seem to be linked to bcp.exe. I have this bcp project properties->Linker->Command Line:

/OUT:"D:\work\prima\build\ext-libs\boost_1_38_0\bin\Debug\bcp.exe" /VERSION:0.0 /INCREMENTAL /NOLOGO /MANIFEST /MANIFESTFILE:"bcp.dir\Debug\bcp.exe.intermediate.manifest" /PDB:"D:/work/prima/build/ext-libs/boost_1_38_0/bin/Debug/bcp.pdb" /SUBSYSTEM:CONSOLE /IMPLIB:"D:\work\prima\build\ext-libs\boost_1_38_0\lib\Debug\bcp.lib" /ERRORREPORT:PROMPT kernel32.lib user32.lib gdi32.lib winspool.lib shell32.lib ole32.lib oleaut32.lib uuid.lib comdlg32.lib advapi32.lib ..\..\lib\Debug\libboost_system-vc80-mt-gd-1_38.lib ..\..\lib\Debug\libboost_filesystem-vc80-mt-gd-1_38.lib ..\..\lib\Debug\libboost_prg_exec_monitor-vc80-mt-gd-1_38-s.lib ..\..\lib\Debug\libboost_regex-vc80-mt-gd-1_38.lib ..\..\lib\Debug\libboost_system-vc80-mt-gd-1_38.lib "..\..\lib\debug\libboost_system-vc80-mt-1_38.lib" "..\..\lib\debug\libboost_regex-vc80-mt-1_38.lib" "..\..\lib\debug\libboost_prg_exec_monitor-vc80-mt-1_38-s.lib" "..\..\lib\debug\libboost_filesystem-vc80-mt-1_38.lib"

Also in Linker->Input I find this:

but not the release versions. When I remove these, the Command Line above does not change.

[chupeev_av@…]

I have the very same problem compiling 64-bit DLL with hand-written makefile or makefile provided with library in folder $(BOOST_ROOT)\libs\regex\build\vc9.mak. To reproduce this error please try to execute command

nmake /nologo /s /f vc9.mak

from within this catalog.

alexander.

[John Maddock]

I don't understand - it works for me.

In any case it's basically impossible to get that error from the regex makefile given that it builds the regex libs, and doesn't use them.

Are you sure you're not invoking one of the CMake generated Makefiles?

John.

PS: The original error messages indicate that two different regex libs are being linked into the same .exe, so whatever the cause this really should be an error.

[chupeev_av@…]

Yes, John. I'm quite shure that I got these errors building dynamic library. I'm stuck with this several days but doesn't yet found a workaround. These are messages generated by linker when I invoke

nmake /nologo /s /f vc9.mak

I found solution for the trouble with LNK2005. This trouble occured if file <boost/regex/config.h> has the following declaration at line 169

extern template class declspec(dllimport) std::basic_string<wchar_t>;

in place of

extern template class declspec(dllimport) std::basic_string<unsigned short>;

This problem doesn't depends whether or not /Zc:wchar_t compiler switch defined. Please take this issue for you information.

alexander.

[anonymous]

I still don't follow, that header *does* have:

extern template class declspec(dllimport) std::basic_string<unsigned short>;

already at that line ???

John.

[chupeev_av@…]

Yes, this is true. I've checked 7z archive originally downloaded from boost site and it has correct declaration. Probably I changed this line by myself trying to make compiler happy and came into trouble. Sorry about that I wasted your time and hastily reported my problem as bug.

[anonymous]

No problem, I like bug reports I can close with no action :-)

Regards, John.

[Steven Watanabe]

Hey. This ticket was originally for a completely different error.

[troy d. straszheim]

I'm inclined to manufacture some reason to bounce it back to somebody else, see how long we can keep up the volley. But alas, bcp builds fine under the current release of alt.boost.cmake.
