Title: Linker warning (SFML-2.0)
Post by: l0calh05t on July 31, 2009, 05:32:52 pm

I'm getting a LIBCMT linker warning when I use the sfml-graphics-s.lib (built from sfml-2.0 svn branch, no modifications). I get the same warning when building the samples that use the graphics lib.

Which warning? With which compiler?

The warning:
LINK : warning LNK4098: defaultlib 'LIBCMT' conflicts with use of other libs; use /NODEFAULTLIB:library

The compiler:
Microsoft Visual C++ 2008 Professional

Try using /VERBOSE:LIB in the extra command line options for the linker. It should tell you a bit more about the problem.

From MSDN

Quote

The run-time libraries now contain directives to prevent mixing different types. You will receive this warning if you try to use different types or debug and non-debug versions of the run-time library in the same program. For example, if you compiled one file to use one kind of run-time library and another file to use another kind (for example, single-threaded versus multithreaded) and tried to link them, you will get this warning. You should compile all source files to use the same run-time library. See the  Use Run-Time Library (/MD, /MT, /LD) compiler options for more information.

Source (http://msdn.microsoft.com/en-us/library/6wtdswk0.aspx)

Im not sure if that quote applies because you are using sfml-graphics-s.lib and it says libcmt witch is the static version. Are you compiling them both in release or both in debug?

both the opengl sample as well as the sfml libraries are built in release mode (and with all settings as per the original vcproj)

and heres the verbose:lib output, although I don't think it's of much use...

Title: Linker warning (SFML-2.0)
Post by: l0calh05t on July 31, 2009, 09:26:45 pm

Just a thought... with which runtime was the included freetype.lib compiled?

Title: Linker warning (SFML-2.0)
Post by: klusark on July 31, 2009, 09:30:14 pm

Hmm I thought verbose would provide some usefull information. Everything looks correct to me.

Hopufully someone knows how to fix this.

Edit after seeing the above post: Were there any warnings when compileing sfml? It would probably have the same warning if freetype.lib was the cause.

Just to confirm, I've been having the same warning with VC2008 Express, with both being release builds. No clue as to what is causing it though.

Title: Linker warning (SFML-2.0)
Post by: l0calh05t on August 02, 2009, 01:53:02 pm

It's definitely freetype. Just built the freetype lib from sources, and now the warning is gone.
