dot config of this case
after compile gcc or on first error :
edit /home/sergio/hardware/moviecube/buildroot/output/staging/usr/include/bits/wordsize.h
and change _MIPS_SZPTR by 32
which is the correct value.
BTW I Had compile all this with buildroot-2010.08
Thanks,

--- Comment #7 from Gustavo Zacarias <[email protected]> --- Try using gcc 4.3.x instead of the (experimental) 4.5.x, this will probably fix most of your constraint issues.
Since gcc 4.4+ MIPS became more sensitive to some optimizations thus breaking some source code.
libmad is fixed in git.
libgcrypt will probably be fixed soon (fixed in my tree
GMP will have to wait IMHO since it's pretty tied up to the internal toolchain. I've got a fix for it but don't expect it to ship for the 2010.11 release since it's part of an internal toolchain revamp.

--- Comment #8 from S?rgio <[email protected]> --- libmad is fixed with last git, great. For me, just libmad was blocker, so I change the bug importance to normal.
Thanks,

After back to gcc 4.3 and with lastest git I had also compile libgcrypt and GMP.
so may be we can close the bug has fixed.
