Issue compiling 2.4test10

Issue compiling 2.4test10

[Eric Reischer]

I am attempting to cross-compile a 2.4 kernel for a PowerPC arch on an 
Intel machine, of which I have Debian 2.2 installed.  I have successfully 
compiled a 2.4test9 kernel, but I got the following error message the first 
time I compiled (it failed due to this):

powerpc-unknown-linux-gnu-ld -T arch/ppc/mm/mm.o <blah blah blah on same 
command for about 11 lines>
drivers/input/inputdrv.o: In function 'keybdev_event':
drivers/input/inputdrv.o(.text+0x16bc): undefined reference to 'emulate_raw'
drivers/input/inputdrv.o(.text+0x16bc): relocation truncated to fit: 
R_PPC_REL24 emulate_raw
make: *** [vmlinux] Error 1


Quoting Martin Costabel <costabel@wanadoo.fr>:

<snip>
The function emulate_raw is used without any ifs, but its definition
some lines earlier is enclosed in either
#if defined(CONFIG_X86) || defined(CONFIG_IA64) || defined(__alpha__) ||
defined(__mips__)
or
#elif defined(CONFIG_ADB_KEYBOARD)
So in your case you would need to put CONFIG_ADB_KEYBOARD=y into your
.config file. Or change these weird #ifs.
The bitkeeper version of the file is somewhat better in that it uses only 
one set of conditionals,
#if defined(CONFIG_X86) || defined(CONFIG_IA64) || defined(__alpha__) ||
defined (__mips__) || defined(CONFIG_PPC)
but the function is still used without any condition.
</snip>

 From what he tells me, this remains an issue in the test10 release.  I 
disabled the entire feature from within xconfig, recompiled, and it 
succeeded.  If you need any more info, let me know and I'll see what I can do.

Would this patch help?

Untested, of course.

I've tried this on my PowerBook and it doesn't work. The keymap is broken and
pressing anything on the keyboard will output something completely different.
This is fixed if the "defined(CONFIG_MAC_HID)" gets move the "#elif" part of
the "#if" mentionned above.

That said, 2 and 3 button emulation is broken for (at least) the PowerBook on test-10.
I've tried the 
echo "1" > /proc/sys/dev/mac_hid/mouse_button_emulation
and there's no effect. Anyone know what this is about?

Thanks.

Fine, my patch made it compile, yours even makes it work. Please post a
diff or send it to Paul Mackerras.

Works for me, you just need to use PC keycodes instead of ADB keycodes if
you want to remap the keys. The default emulation codes are for fn-opt and
fn-cmd.
