[Gems-users] Problem with compiling ruby on RHEL5 64bit

[Zya Zya <yuangge@xxxxxxxxx>]

Hello
I think I meet a problem with compiling ruby.
The OS is RHEL5 64bit. When I  compile ruby with "make PROTOCOL=MOSI_SMP_bcast DESTINATION=MOSI_SMP_bcast"
There is an error as following:
generated/MOSI_SMP_bcast/attrparse.c:1: error: CPU you selected does not suppo x86-64 instruction set
When I change -march from i686 to be x86-64, another problem comes out.
Has anyone meet such problem before? How do you handle this?

Thanks a lot and merry Xmas!
