I added the option -undefined warning because of the undfined symbol of the Timer and with clang ld it is not possible to have undefined symbols, with gcc it is the opposite default behavior, to have the same behavior I thought -undefined dynamic_lookup was the best option but I had other problems with cast_of_pointer after that (not knowing if it is related or not). The -flat_namespace is mandatory if you use -undefined warning as clang use a two level namespace by default. dlopen and flat_namespace are linked for resolving symbols see here with RTLD_GLOBAL. Linux shared libraries behave as if -undefined dynamic_lookup is enabled all the time.
On Mac OS X, RTLD_GLOBAL is the default. On Linux RTLD_LOCAL is the default.
otool -hV to see if TWOLEVEL is present or not.
