Compiling 64-bit FLAC/libFLAC in OS X Lion

Question

I'd like to use the libFLAC dynamic libraries in an app I'm trying to build, but I'm not too familiar with configure and make arguments to actually get FLAC to compile.

I have tried to CC="gcc -m64" CXX="g++ -m64" ./configure and that appears to run fine without issues, but when I run make, I still get

[...lots of output with seemingly no errors...]

Any suggestions?

To get this to compile on Lion, disable assembler optimizations:

% ./configure --disable-asm-optimizations
