error LNK2005: _DllMain@12 already defined in MSVCRT.lib

Question

I am getting this linker error.

mfcs80.lib(dllmodul.obj) : error LNK2005: _DllMain@12 already defined in MSVCRT.lib(dllmain.obj)

Answer 1

If you're defining your own DllMain, in your project settings you need to set 'Use of MFC' in the 'Configuration Properties/General' to 'Use Standard Windows Libraries'.

You should do a clean rebuild after changing it.
