Re: [ft-devel] Build freetype2 64bit in windows
Dear 晓明, I've just stumbled across your old e-mail from April the 12th. freetype-2.4.9\src\bdf\bdflib.c(772): warning C4244: “function”: conversion from 'ptrdiff_t' to 'unsigned long', possible loss of data error = (*cb)( buf + start, end - start, lineno, (void*)cb, client_data ); Fixed. freetype-2.4.9\src\base(39): warning C4306: “function”: conversion from ' int ' to ' FT_Pointer ' of greater size if ( svc == FT_SERVICE_UNAVAILABLE ) // this line: FT_SERVICE_UNAVAILABLE is defined to ((FT_Pointer)-2) I think I've fixed this and similar issues by using the `logical not' operator (~) instead of a negative value. Please test the current git. freetype-2.4.9\src\type1\t1load.c(618): warning C4244: “function”: conversion from 'FT_PtrDist' to 'FT_Long', possible loss of data if ( FT_ALLOC( blend-axis_names[n], len + 1 ) ) Fixed. If you still get warnings please send the complete output to the list. Werner ___ Freetype-devel mailing list Freetype-devel@nongnu.org https://lists.nongnu.org/mailman/listinfo/freetype-devel
[ft-devel] Build freetype2 64bit in windows
Hi, I am using solution file 'freetype.sln' in vc2010 directory to build freetype 2.4.9. I create new configuration for x64, and the build process has no error but with many warnings. I see warings for these: convert ptrdiff_t to unsigned long convert int to FT_Pointer convert FT_PtrDist to FT_Long convert int to FT_UShort* How should I configure my 64bit project for vc2010 to avoid these? I think these pointer operations aren't correct. Thanks. ___ Freetype-devel mailing list Freetype-devel@nongnu.org https://lists.nongnu.org/mailman/listinfo/freetype-devel
