General / [Fixed] Visual C++ - Linking error with /MT option.

« on: April 21, 2010, 12:39:22 pm »

Hi, there. I'm using SFML 2.0 (rev. 1516) and Visual Studio 2008.

Before I use this, rev 1516, there is no error to compile.

Code: [Select]

Yes, this is the problem "/MT" and "/MD" option to link.

But in the past, compiled with no error.

And I was found what extra library has changed to static library.

I think png.lib or jpeg.lib compiled with "/MD" option.

If this is correct, I don't want to use "/MD" option because it needs MFC DLL.

Is there another solution in this case?




FIX: not MFC DLL, it needs MSVCR90.dll.
