[Clfs-dev] Building cross tools for PPC (big endian) from x86 fails. (GCC PR41818)

[code monkey]

Using the current development version...

The cross tools gcc-final step fails when building for PPC (or SPARC) from
an X86.       This appears to be due to gcc bug PR41818:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41818

There is a patch attached to that PR.   I applied the patch and the build
then succeeded and the resulting system was functional.   (I also updated to
GCC 4.4.3 at the same time although probably not required..).

Can this patch get added to the book?



FYI: the error in the gcc-final log is:
===========================================================
checking for C compiler default output file name... configure: error: in
`/mnt/clfsdev/sources/gcc-build/sparc-unknown-linux-gnu/libgomp':
configure: error: C compiler cannot create executables

But the libgomp gives a better failure description:
