i cant make config for any 2.6 kernel, or install any 2.6 header package:
Dual-G5 ppc64-sources-2.6.4-ames1-r1 # make config
make: `scripts/fixdep' is up to date.
In file included from /usr/include/asm/cputable.h:18,
/usr/include/linux/config.h:4:28: linux/autoconf.h: No such file or directory
make: *** [scripts/kconfig/mconf.o] Error 1
make: *** [config] Error 2
the kernel probably shouldnt be pulling headers from /usr/include...
this is fixed simply by doing a touch /usr/include/linux/autoconf.h
once ppc64-headers is reinstalled after touching the file:
Dual-G5 root # qpkg -f /usr/include/linux/autoconf.h
Dual-G5 root # cat /usr/include/linux/autoconf.h | wc -l
it appears that ppc64-headers installs properly as long as this file exists, and wont if it doesnt. it doesnt really matter much what's in the file... perhaps this merits an addition to the kernel eclass?
this seems to be ok with 2.6.6.
going to close it out.
