Bug 88749 – fix glibc-2.3.4.20050125-r1 ebuild for ppc64 cross-compile

• Product: Gentoo Linux
• Status: VERIFIED FIXED

[Description Chris Parrott (RETIRED) 2005-04-11 10:36:55 UTC]

Now that the gcc-3.4.3.20050110-r2 cross-compiler is working for powerpc64, I attempted to build a corresponding cross glibc for compiling powerpc64 binaries from amd64.  Unfortunately, the emerge died with the following message at line 1001 in the ebuild:

ppc64 crosscompile not yet supported.  Bug a ppc64 dev to fill in the CDEFINE values in the glibc ebuild.

This is apparently due to the fact that CDEFINE_ppc and CDEFINE_ppc64 at lines 991 and 996 (respectively) are not defined.

By examination of the glibc source files, I have determined the proper values for these variables, and filled them in.  I was then able to successfully emerge a cross-powerpc64 version of glibc from amd64 with this.  I then verified that this toolchain will compile and link working binaries that run on ppc64 Linux.

I will attach my modified ebuild that fills in the correct values, and I would appreciate it if someone could evaluate it and commit it to the portage tree if deemed acceptable.


Reproducible: Always
Steps to Reproduce:
1.  Follow steps at http://dev.gentoo.org/~vapier/CROSS-COMPILE-HOWTO, using cross-powerpc64-unknown-linux-gnu instead of cross-hppa2.0-unknown-linux-gnu.
2.  Step (7) fails with the error message mentioned in the Details section.
