Ok. > Have you tried building a kernel with that biarch compiler? What do I > set GCC and LD to? Yet, but it has been a while. it needs gcc-3.4 obviously, and you need to build with ARCH=ppc64 i think, or something such. Last i tried was with the debian 2.6.8 kernel, and the build system failed for some obscure reason to pass the 64bit flag, and i haven't had time to do this first, and the fact that this compiler is not in sarge or even experimental somewhat discouraged me. The easiest way would be to have a pseudo-package which contains only the glibc headers, but externally to the glibc package per see, this way we could have a biarch compiler in sid/experimental, without a new glibc. This would not be really all that usefull as a full biarch toolchain, but already something. > I am also having trouble getting a simple test program to link (I'm > trying to use the libc.a from the ppc64 chroot) Ah, i had no problem with the crosstools, but using a cross compiler causes other problems since make-kpkg was not really cross-compiler friendly. I will have a go at this another time next week, once 2.6.11 is nicely out of the way ? Friendly, Sven Luther -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
