Thanks for your kindness. No, I don't want a crosscompiler actually. I just want a higher version of GCC on my system in order to run OpenMP programs. At the beginning, the problem is that it cannot locate "stubs-64.h" file which is included in "features.h". As I am really new to the make of GCC, I cannot find a suitable solution. So I simply checked the configuration of the original GCC by "gcc -v" and specified the target as "--target=sparc-linux-gnu" when I configured the new one. Maybe I shouldn't have done this? If not, what should I do? Thanks again! On 8/13/07, Kai Ruottu <karuottu@xxxxxxxx> wrote: > jiaqi zhang wrote: > > I'm compiling gcc-4.2.1 on a sparc64 system.
