[test] Fatal link error LNK1561: entry point must be defined when using boost.test

[Tjernstrom, Staffan]

(Resend with modified subject to better match list standards)

Folks,

Hopefully this is me having finger trouble, but I can't seem to get around the problem.

Boost 1.35 installed using the binary installer, all the vc8 flavours installed.

What happens is that I try to compile / link any of the unit test examples in Visual Studio 2005 Pro, for example the code at

http://www.boost.org/doc/libs/test/example/unit_test_example_05.cpp

I keep getting the LNK1561: entry point must be defined error. I know that it's looking for, and picking up, the libboost_unit_test_framework-vc80-mt-1_35.lib as if I remove the /LIBPATH from the link command options it compains that it cannot find that library.

I have my project settings set as follows:

Compiler:
/O2 /GL /I "C:\Program Files (x86)\boost\boost_1_35_0" /D "_MBCS" /FD /EHa /MD /Fo"Release\\" /Fd"Release\vc80.pdb" /W3 /nologo /c /Wp64 /Zi /TP /errorReport:prompt

Linker:
/OUT:"D:\staffan\Documents\Visual Studio 2005\Projects\CeT3x\test\AllUnitTests\Release\test_XOLibrary.exe" /NOLOGO /LIBPATH:"C:\Program Files (x86)\boost\boost_1_35_0\lib" /MANIFEST /MANIFESTFILE:"Release\test_XOLibrary.exe.intermediate.manifest" /DEBUG /PDB:"d:\staffan\Documents\Visual Studio 2005\Projects\CeT3x\test\AllUnitTests\release\test_XOLibrary.pdb" /OPT:REF /OPT:ICF /LTCG /MACHINE:X86 /ERRORREPORT:PROMPT kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib

Any thoughts anyone?

Every time I try to click on a unit test example link I have been
getting a 404 error :(
Can other people use links like this?

Does it work if BOOST_TEST_MAIN is defined?

--John Femiani

[Tjernstrom, Staffan]

No, unless I also define BOOST_TEST_DYN_LINK, but then I have to copy across the boost test dll (it's not picked up in the manifest by default).

As far as I can tell, the culprit seems to be the following in <boost/test/unit_test.hpp>

//____________________________________________________________________________//

// ************************************************************************** //
// ************** Auto Linking ************** //
// ************************************************************************** //

#if !defined(BOOST_ALL_NO_LIB) && !defined(BOOST_TEST_NO_LIB) && \

# if defined(BOOST_ALL_DYN_LINK) || defined(BOOST_TEST_DYN_LINK)
# define BOOST_DYN_LINK
# endif

# include <boost/config/auto_link.hpp>

}}

Open a VS command prompt window, go to the lib folder, and type:

dumpbin libboost_unit_test_framework-vc80-mt-1_35.lib /LINKERMEMBER >
symbols.txt

Then open symbols.txt and search for _main.

If its missing, try rebuilding the lib.

I get the same error. The correct link is
http://www.boost.org/doc/libs/1_35_0/libs/test/example/unit_test_example_05.cpp

The problem here is that you set to link against dynamic version of C++
runtime and you want boost to link against static version of boost lib. This
will not work.

Please select either another compilation switch (Project Properties / C++ /
Code Generation) and choose there non-DLL version of runtime, like
Multi-Threaded Library and not as currently Multi-Threaded Library DLL. This
should change your compiler switch from /MD to /MT.

C++ will afterwards look for the satic version of the test library, which
has the prefix libboost_*.lib instead of boost_*.lib


Good Luck,
Ovanes

I dont think that is the problem because he is linking with
libboost_unit_test_framework-vc80-mt-1_35.lib, and since there is no
'-s' in the name, it links with MSVCRT, and it is selected by boost
autolink when you use option /MD and and you are not compiling DEBUG code.

Plus, it works flawlessly on my system.

I _did_ notice a difference between our liker options; You don't have
the subsystem set. When I throw together an msvc project I get this
linker option:

/SUBSYTEM:CONSOLE

If I remove that option, I get:

1>LINK : fatal error LNK1561: entry point must be defined

Personally, I never even paid attention to it before (the defaults
always worked for me), but I guess that is probably your problem.

open your project properties, and change Linker->System->SubSystem from
[Not Set] to '/SUBSYSTEM:CONSOLE', or just manually add it to the
command line and see if that works.

[Tjernstrom, Staffan]

Thank you very much indeed.

The missing /SUBSYSTEM: was indeed my problem.

This came about because I created the unit test projects as empty projects in VS, not MFC console projects.
