[fluid-dev] Universal binary of libfluidsynth

[Nathaniel Gray]

One more thing,

I just wanted to report that I was able to build a universal binary  
of libfluidsynth on OS X with a bit of work.  I configured with the  
line:

env CFLAGS="-isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch i386 - 
arch ppc" \
  LDFLAGS="-arch i386 -arch ppc" ./configure --disable-dependency- 
tracking \
  --disable-alsa-support --disable-oss-support --disable-jack-support \
  --without-readline --disable-ladcca --disable-lash

But I also needed to fix the endianness macro in src/config.h, since  
it needs to detect endianness at compile time, not configure time:

/* Define to 1 if your processor stores words with the most  
significant byte
   first (like Motorola and SPARC, unlike Intel and VAX). */
#ifdef __BIG_ENDIAN__
# define WORDS_BIGENDIAN 1
#else
# undef WORDS_BIGENDIAN
#endif

For some reason the ldflags don't get through properly (the -arch  
flags, specifically), so I did:

make   # This fails
cd src
# Rebuild libfluidsynth.1.1.1.dylib as universal binary library

libfluidsynth.1.dylib -Wl,-compatibility_version -Wl,3 -Wl,-

cd ..
make

And that did the trick.  I'm no autoconf expert so I can't tell you  
how to solve these problems, but I sure would be happy if you did.  ;^)

Cheers,
