I changed the MakeUUID in sqUnixUUID.c to look like following: int MakeUUID(char *location) { uuid_t uuid; #if defined(HAVE_UUIDGEN) uuidgen(&uuid, 1); #elif defined(HAVE_UUID_GENERATE) uuid_generate(uuid); #else #error "No uuid function provided" #endif memcpy((void *)location, (void *)&uuid, sizeof(uuid)); return 1; } and during compiling cocoa vms it fails with error. And before change the code was looking like following: int MakeUUID(char *location) { uuid_t uuid; #if defined(HAVE_UUIDGEN) uuidgen(&uuid, 1); #elif defined(HAVE_UUID_GENERATE) uuid_generate(uuid); #endif memcpy((void *)location, (void *)&uuid, sizeof(uuid)); return 1; } which means that if none HAVE_UUIDGEN or HAVE_UUID_GENERATE is defined, then there is nothing got called and memcpy then returns a random values on stack, copied from uuid to locaiton. And first version of that file just contains : int MakeUUID(char *location) { uuid_t uuid; uuid_generate(uuid); memcpy((void *)location, (void *)&uuid, sizeof(uuid)); return 1; } and then changed to: #if defined(__NetBSD__) uuidgen(&uuid, 1); #else uuid_generate(uuid); #endif and then changed to: #if defined(HAVE_UUIDGEN) uuidgen(&uuid, 1); #elif defined(HAVE_UUID_GENERATE) uuid_generate(uuid); #endif Blame: Merge Levente's linux UUIDPlugin fix. Fix tickerSleepCycle decl in heartbeat. Restore -O2 optimization for the interpreter.
