Thanks. But the -fno-common didn't work, neither did the -undefined suppress flag...
I still have :

ld: common symbols not allowed with MH_DYLIB output format
foo.o definition of common _foo (size X)
...

where _foo is the symbol of a global variable. So it seems global variable symbols are not supported at all in MH_DYLIBs, or I am missing a flag...
But in my case, I have no really need to share the symbol outside of the lib. I just want it to be statically linked with the library code. How can I tell to dyld which symbols should be exported and which should not ?
