Problems in compiling for mips

Fri Apr 4 17:03:41 UTC 2008

thanks for the reply :).
when i checked the linux src for mips in asm-mips folder PAGE_SIZE was
defined only in kernel context.
if __KERNEL__ was defined only then was PAGE_SIZE defined. on the other hand
PAGE_SIZE is defined for non kernel context in i386 and arm asm folders. i
was able to fix the problem by defining PAGE_SIZE in asm-mips/page.h. that
compiled the uClibc-0.9.26, then i compiled full build of gcc-3.3.3 and also
was able to run test programs on the ubnt litestation2 mips-4kc board.
 isnt there a patch available for doing this the right way? i understand
that making changes in the kernel code is not a good idea. is there a fix
available for this problem?
i would like to post my findings about the toolchain build procedure but not
before getting the right solution for this problem.

regards
