the main reason for this warning is that different kinds of the runtime library was used by different files. say if you compiled a source by using single-threaded runtime library (or linked against a .obj or .lib file which was compiled with single-threaded runtime library) and have another source that was compiled with multi-threading debug runtime library. <br />

you can find out what is going wrong by doing a build with the /VERBOSE:LIB option. you can add this build option by going to the linker properties - command line and add the option by directly editing the 'All Options' window. if you then start the build, the build output should contain all libraries which are searched. if there is both libc.lib and libcmt.lib in the output, you have found one of the differences which caused the linker warning.<br />
