[GEM-dev] compiling GEM externals on OSX (was: [PD] lua scripting for pd objects)

[marius schebella]

hi cyrille and frank,

it was not so easy on osx, I got an error with -export_dynamic because 
gcc does not know this flag on osx.
then I tried to remove it, but some other errors showed up.
I then looked how gem gets compiled on my machine and took "inspiration" 
from there to finally get an mscube compiling as a standalone gem 
external on osx: here are the flags that I used:

g++ -c -I/sw/include -g -O2 -fPIC -freg-struct-return -Os 
-falign-loops=32 -falign-functions=32 -falign-jumps=32 -funroll-loops 
-ffast-math -mmmx -fpascal-strings   -I.. 
-I/Users/marius/devel/pd-rsync/pd-extended/Gem/src 
-I/Users/marius/devel/pd-rsync/pd-extended/pd/src  mscube.cpp -o mscube.o

g++ -o mscube.pd_darwin -dynamiclib -mmacosx-version-min=10.3 -undefined 
dynamic_lookup -framework QuickTime -framework Carbon -framework AGL 
-framework OpenGL ./*.o -L/sw/lib -ldl -lz -lm -lpthread 
-L/Users/marius/devel/pd-rsync/pd-extended/pd/bin

rm -f *.o

I am not sure if I need all of these flags and how to write a beautiful 
makefile with variables, but with some help, I hope I will figure out.
with the above information, do you think it would be possible to have 
one makefile for linux and darwin?

marius.
