No, it's an integer conversion error. The line 159 in bench.c had to be changed for ppc compatibility: Print(4095, "Raw nodes per second: %d\n", (int) (nodes / (total_time_used / 100))); > >Could I get a quick explination of the SMP time-to-ply value? > >Also, >I would appreciate a updated make file for crafty for a dual G5. >I made the changes based on previous posts but could use some help with command >line programming. >Make files, include files, and file chanages would help. > >William A Makefile optimized for Dual G5 plus the above bench.c fix plus some inline functions for ppc can be found below. I didn't change any other crafty code except of this enhancements and fixes for ppc. http://home.datacomm.ch/aguettinger/files/crafty-19.17ppc.tar.gz cu Andy
