When trying to compile the 2.3.47 linux distribution from a kernel.org
mirror, I don't get a macintosh.a file built in my drivers/macintosh/
directory. As a matter of fact, I don't seem to get any macintosh
drivers built in that directory as there's no .o files at all. Anyone
else experience this? I've tried poking around to discover where the
error could be but so far I'm clueless about this. Am I doing something
wrong with my .config configuration info? I've attached my .config file
in case this could be it and someone could check it. Any other
possibilities?
BTW: I did have to make some minor changes to get even so far as to try
linking it all together. I've attached the context diff of my mem.c file
which I had to change to get it to compile. Could my simple change be
the right thing to have done for the mem.c file???
Thanks for any help!

Aha! I found I needed to change (fix?) drivers/Makefile to essentially add in
the macintosh subdirectory like for CONFIG_MAC but for CONFIG_PPC. I've
attached this context diff.

Now the linker gets the macintosh.a stuff but spews out about some undefined
references and fails. I suspect I may be able to fix this by changing my
configuration. If anybody knows better, please let me know too. The actual
undefined references are to: find_via_pmu, pmu_poll, backlight_level,
pmu_set_brightness, and vgacon_remap_base.
Advanced thanks ;-)

This is because there is Powerbook code without #ifdef CONFIG_PMAC_PBOOK
around it. Here is a quick patch:

Thanks. This seems like a far better fix than what I wound up doing: just setting
CONFIG_ADB_PMU=y (I have a PowerMac 7500 not a Powerbook after all) and I'm gonna
recompile with your fix instead. So now I'm wondering how many people (if any) are
actually running 2.3.47 from kernel.org and happy with it especially for a
PowerMac7500. Thanks!
