Problems building with VC++ 6.0

Hi everybody,

When i try to build  my project, which contains the cppunit tests, I have this errors :

LIBCD.lib(crt0.obj) : error LNK2005: _mainCRTStartup already defined in
MSVCRT.lib(crtexe.obj)
LIBCD.lib(dbgheap.obj) : error LNK2005: _free already defined in MSVCRT.lib

It seems to be a problem with the librairies. Do someone know hox to fix that?

Thamks,

Try ignoring the msvcrt library by changing the  project settings:
- Link tab - category "input" - Ingore Libraries: "msvcrt.lib"

thanks, ignoring the "msvrct.lib" librairie works, but now when I execute my project, it says that the cppunit_dll.dll can't be found and that I have to reinstall cppunit.

When it tryed to add cppunit_dll.dll in project settings/ link (for now I only link cppunit_dll.lib and cppunitd_dll.lib), I have an error when I build the project :
cppunit_dll.dll : fatal error LNK1136: invalid or corrupt file

Do you know how to fix it?
Thanks

You're most likely not using the same c run-time library as cppunit.

Check the Projects settings/C++/Code generation and compare between the cppunit project and yours (should be (debug) multithreaded dll if my memory does not fail me).

I'm not sure that ignoring the library is the right thing to do (likely to result in crash at run time).

You never add .dll to a project, just the .lib that come along with it.

For the .dll to be found, it need to be in one of the directory in your PATH or in the same directory as your executable. Try to copy the .dll to the Debug and Release build directory, that should do the trick.

You can also try linking against the non dll version of cppunit (cppunit.lib & cppunitd.lib), though you will not be able to use the test plug-in stuff.
