As I understand Arasan does only support march=i686. The problem seems to be the bits.s file that is written in assembly for x86 cpus. Now this not supposed to be a critic to Arasan but goes to all the programmers out there. I understand the joy to make your move generators 5% faster by using assembler. But please keep in mind that there are some people out there that are not going with the flow and are using other architectures. Would it be that hard to include some C routines that one can decide to use instead of the assembler routines? It would be nice to have some sparring partners also on other platforms. regards Andy
