Some more informations on that matter, a 64 bits process cannot access 32bits address space directly (and vice-versa), you need a proxy process for that (example being some 32bits plugins for a 64 bits browser): http://stackoverflow.com/questions/2412893/making-a-64-bit-shared-library-that-dynamically-links-to-a-32-bit-library-on-mac Concerning the possible usage of arch triple for target (lib or exe) built using CMake and how to define it, I think the work done on Debian Multiarch contains interesting discussions and ideas; http://wiki.debian.org/Multiarch So may be TARGET_ARCH should be a triple as well (including in the Windows and OS X case) -- Erk Le gouvernement représentatif n'est pas la démocratie -- http://www.le-message.org
