Hi! There's a piece of MSVC inline asm in libFLAC as of flac-1.2.1 that doesn't respect the FLAC__NO_ASM constant. It's causing trouble only when compiling with MSVC _and_ targeting x64 (since inline asm doesn't work in x64). I've attached a patch that fixes the issue to this mail. When applied, flac-1.2.1 compiles on Windows x86 and Windows x64 flawlessly. Playback seems fine from what I can tell! -Markus- -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...
