Link problem on MS VC++6 & .NET

SDL Development
1

It seems to be a conflict between msvcrt.lib & libcmt.lib
I have this problem a long time ago but I correct it (I dont remember how)

Any suggestions???

I include a piece of code for MS VC++ .NET

Thanks================================================================

I get so many damn errors from vc++ its not even funny. I know you can
prevent the warning

LIBCMTD.lib(crt0init.obj) : warning LNK4098: defaultlib 'msvcrt.lib’
conflicts with use of other libs; use /NODEFAULTLIB:library

by putting ‘msvcrt’ in Property->Linker->Input->Ignore Specific Library
I also have LIBCD in there but I don’t think that is causing the other
errors.

If you figure out how to fix those, let me know!

I see now that:
In FAQ of SDL there is a question about my problem and the answer is try the
multithreaded C++ libraries!!!
I have activated the multithreaded libraries from the beginning…

I include the whole MS VC++ .NET project again.
Please take a look if you know an answer…

I can’t test this in v6, but I know it works in .Net (2002 Standard,
atleast) – it’s pretty much what I do (actually, I directly throw the
/NODEFAULTLIB switch into the command line, but it’s the same effect)
