[OpenAFS-devel] Another build problem on sparc-linux

[Dean Anderson]

Ok, I found some joy, in configuring the both the afs toplevel to be
sparc64_linux24 and then building only_libafs_tree, and then configuring
that as sparc64_linux24. Then changing the CC=sparc-linux-gcc to CC=kgcc
in the libafs Makefile.

Then Everything seems to compile, but I get these messages about
redefinitions of exported kernel symbols. I've seen this error before when
trying to build modules in the linux tree without first building a
kernel...
