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,

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.

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.
