On MacOSX this includes pwd.h which in turn includes the system uuid/uuid.h, which causes a compile failure if QEMU was configured without CONFIG_UUID due to a conflict between the system header and our fallback versions: block/vdi.c:124:20: error: static declaration of 'uuid_generate' follows non-static declaration static inline void uuid_generate(uuid_t out) ^ /usr/include/uuid/uuid.h:63:6: note: previous declaration is here void uuid_generate(uuid_t out); ^ Fix this breakage by improving configure's check for uuid to work on MacOSX (where there is no need to link in a separate libuuid). Note that if the user explicitly runs configure with '--disable-uuid' on MacOSX then QEMU will fail to compile.
