klibc - Jul 2006 - klibc parisc64

I hacked out a rough first implementation of parisc64 for klibc
last month, and only just got around to testing it now.

The good news, it compiled fine on the first shot. The bad news,
it failed to link usr/klibc/libc.so, and I'm not clueful enough
to know why.

You can fetch it from
git://git.kernel.org/pub/scm/linux/kernel/git/kyle/klibc-parisc64.git,
and compile it with:

make CROSS_COMPILE=hppa64-linux-gnu- ARCH=parisc64 V=1

(It seemed to build without warning on my Debian etch rp2470)

Any hints would be appreciated.

Cheers,

This is a ld bug.  I see the same problem on hpux with '-static'.  We
need another program header sometimes and I haven't figured out why.
I had a hack on my A500 that I might be able to find but it's down at
the moment.
