flac dev - Sep 2004 - linking with libFLAC on Mac OS X

Hi everyone.

I'm working on a FLAC plugin for the Java Media Framework (JMF) on Mac 
OS X.  I'm having some trouble linking to libFLAC... When I first try to 
link to it, it tells me the libFLAC.a TOC is out of date, so run ranlib. 
  So then I run ranlib, and it seems to be okay, except I then get 
undefined symbol errors:

% cc -bundle -I/System/Library/Frameworks/JavaVM.framework/Headers 
-I./flac-1.0.2-osx-ppc/include/ -L./flac-1.0.2-osx-ppc/lib/ -lFLAC -o 
libflacjmf.jnilib -framework JavaVM flacdecoder.c
/usr/bin/ld: Undefined symbols:
_FLAC__stream_decoder_process_metadata

I've tried it even without the Java-specific options, and it still fails.

Has anyone had any luck linking with libFLAC on OS X?  Any help would be 
appreciated.

Thanks,
Chris

In general, you should link libraries in at the end of the command line.
This is so that unresolved symbols which are found earlier in the command
line can be correctly resolved.  Try moving -lFLAC to the end.
