I was pretty surprised myself. But it seems that's the path they chose: fluffy% gcc test.c -o test fluffy% file test test: Mach-O 64-bit executable x86_64 fluffy% otool -h -v test test: Mach headermagic cputype cpusubtype caps filetype ncmds sizeofcmds flags MH_MAGIC_64 X86_64 ALL LIB64 EXECUTE 11 1536 NOUNDEFS DYLDLINK TWOLEVEL
fluffy% gcc -arch i386 test.c -o test fluffy% file test test: Mach-O executable i386 fluffy% otool -h -v test test: Mach headermagic cputype cpusubtype caps filetype ncmds sizeofcmds flags MH_MAGIC I386 ALL 0x00 EXECUTE 11 1172 NOUNDEFS DYLDLINK TWOLEVEL

Is it really true that 10.6 gcc defaults to producing 64-bit binaries? I imagine that would break a lot of traditional UNIX builds. If so then we will need to either have better detection of bittedness or simply force gcc to 32-bit mode unless the ARCH is specified as 64-bit. 64-bit works perfectly fine on OS X, except that you must remember to build all your local libraries in 64-bit mode. If 64-bit is now the standard output format, then this is not an issue and we should prefer 64-bit when available. I do not have a copy of 10.6 to play around with yet though.On Sat, Aug 29, 2009 at 9:56 PM, Jim Ursetto<address@hidden> wrote:It might be easier to compile with make PLATFORM=macosx ARCH=x86-64 as stated in the README.
