AFAIK, it can be compiled with -m32, but not with -m64, that's the reason I haven't packaged it for Debian yet, although I've been following the project since its birth. Fenix also had, and already has, that problem. Maybe it could be fixed with intptr_t and uintptr_t [1] (Linux equivalent for Window's UINT_PTR and INT_PTR [2]), but as that numbers are part of the virtual machine code, that would make code not portable between architectures (I seriously doubt that it is now, even in 32 bits with different endianess, but I haven't checked so I might be wrong). The proper way to fix it would probably be to have a dictionary (or something EQUIVALENT), and put the key to the dictionary in the id and the pointer in the value, thus avoiding having the actual pointer in the 32bit id [3] Whatever the solution might be, it seems to imply a hard work, so for the moment I would only consider using it in 32 bits arches. Any better ideas?
