Hi , I am facing one strange problem ... I have two MAC machines A and B . Both have same versions of gcc/bin utils/ld gcc version 3.3.5 (Debian 1:3.3.5-13) GNU ld version 2.15 I have been trying to bulid some kernel for powerPC on these for e300/e500/e600 core. Now on 'A' everything builds on 'B' e300/e500 builds but e600 comes out with this error kernelPath/cpu/e600/e600.S:2119: Error: Unrecognized opcode: `dcba' While buliding kernel the only noticable difference is that there is this warning which comes while building (for each component) Warning: File `kernelPath/kernel_defs.h' has modification time 4.8e+02 s in the future and the other diffence is in the uname which for the local MAC machine is for A : Linux A 2.6.8-customsmp2 #1 SMP for B : Linux B 2.6.8-powerpc-smp I am surprised at this behavior. Gcc/binUtils versions are same , machines are natively MAC then why two different behaviors ? Any help would be greatly appreciated.
