Hi, -mcpu is deprecated in 3.4.x, you would use -mtune instead. -mtune tries not to break the compatibility with processors of the same familly -march will try to use the whole ABI of the processor, therefore compatibility can be broken If everything you compile is used on your computer, I would advice to use -march for maximum performance. -- [email protected] mailing list
