MSCMS tests fails on my box: | [s2(a)katleriai wine]$ wine dlls/mscms/tests/mscms_test.exe.so 2>&1 | head -n 6 | This version of Wine was compiled without support for color management | functions. This means many color functions are empty stubs and you should | expect your application to fail. To enable Wine to use LittleCMS for color | management please install a liblcms development package version 1.13 or | higher and rebuild Wine. | http://www.littlecms.com I want to fix this by avoiding to upgrade my liblcms and install dev-pkg. Would it be OK to put some #ifdef-s in some unimplemented function, let say EnumColorProfilesA(), and to SetLastError(ERROR_CALL_NOT_IMPLEMENTED)? Then at the start of the test we could check this and return from the test when GetLastError() return ERROR_CALL_NOT_IMPLEMENTED. Is this way OK?
