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?

  • Sounds similar to [this issue](http://stackoverflow.com/questions/1185287/compiling-imagemagick-as-64bit-under-os-x) – user1118321 Jan 01 '12 at 18:42
  • @user1118321 Actually, the answer to that question is where I got the configure flags that I've used above, but they do not seem to work in this situation. – ray Jan 01 '12 at 21:50
  • It is different from the linked issue in that in this case, you are compiling C files as 64-bit by default (it is so since Snow Leopard and continues with Lion. `CC="gcc -m64" CXX="g++ -m64"` doesn't do anything) and your problem arrives when trying to link these files with object files that were generated from IA32 assembly. You could try `CC="gcc -m32" CXX="g++ -m32" ./configure`: at least it will have some effects (I can't guarantee they will be positive). – Pascal Cuoq Jan 01 '12 at 22:38

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

% ./configure --disable-asm-optimizations
