I realise this is off-topic for SDL, but I know that there are many
people here who will have dealt with this problem and it will most
likely be relevant for people trying to make their code portable:
How does one create shared libraries on OS X?
I used to use this:
cc -o file1.o -c -fPIC file1.c
cc -o file2.o -c -fPIC file2.c
cc -o file3.o -c -fPIC file3.c
libtool -dynamic -o libfile.dylib file1.o file2.o file3.o -lc
This works on everything pre OS X 10.4. Note that libtool isn’t
GNU libtool, it’s some utility bundled with OS X. That caught me
out at first! OS X 10.4 fails with some linker errors:
ld: for architecture ppc
ld: Undefined symbols:
_printf$LDBLStub
libtool: internal link edit command failed
Not really much help, to be honest.
The ADC site suggests a method that looks very odd, and even
suggests that modifications to the source must be made, which
is unnacceptable in my view (it smells of vendor lock-in).
Any suggestions?
thanks,
MC
