[sword-devel] Compile Sword as Universal on Mac

[Manfred Bergmann]

Hi.

No, that's no correct. You can build universal binaries on every  
machine be it PPC or Intel.

Below is an excerpt of the MacSword Sword library build script which  
builds first PPC against 10.3.9 SDK and then Intel against 10.4u SDK  
and then the two binaries are bound together with "lipo" tool.
Mac OSX itself then finds out which binary version it needs.

# build stuff
if [ $PPC -eq 1 ] || [ $FAT -eq 1 ]; then
	cd trunk
	#make clean
	./autogen.sh

	export SDK=/Developer/SDKs/MacOSX10.3.9.sdk
	if [ $DEBUG -eq 1 ]; then
