While compiling freetype2 for Win64 to meet a VLC dependency, I encounter these warnings:

On this platform, they are not. I looked into some of them, and I see for instance this: /*************************************************************************/ /* */ /* <Type> */ /* FT_Fixed */ /* */ /* <Description> */ /* This type is used to store 16.16 fixed float values, like scaling */ /* values or matrix coefficients. */ /* */ typedef signed long FT_Fixed; Well, that's an easy fix. Just change signed long to intptr_t, and problems are solved. However, the comments in the typedef say that FT_Fixed is expected to be 16 bits by 16 bits. This isn't the cast even on a linux 64 system, where long is 32.32. Further, why is a type like this being used to store pointers? Surely a pointer isn't a matrix coefficient. I want to be able to properly port this, but it seems like this isn't as trivial as just replacing a bunch of long's with intptr_t's. Where should we go from here? _______________________________________________ Freetype mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/freetype
