Bugzilla Bug 194903

I have not had any problem with this before (since at least 2.6.10), and that
includes 2.6.22-r5.

I need to generate the keymap, so I always change two lines in
/usr/src/linux/drivers/char/Makefile

First, uncomment line 121 to:

GENERATE_KEYMAP := 1

Second change line 125 to give the complete path:

- $(obj)/defkeymap.c $(obj)/%.c: $(src)/%.map

+ $(obj)/defkeymap.c $(obj)/%.c:
/usr/src/linux-2.6.22-gentoo-r8/drivers/char/defkeymap.map

Note this used to work in any 2.6.18 and before version without modification,
but does not in any 2.6.19 and after.

I get the same behavior both before and after the linux-headers upgrade.

$ emerge -p --info

I will attach a file of the compilation failure.

output from compilation

You don't need to make that second modification to the Makefile (ie. change the
path) : just uncomment the "# GENERATE_KEYMAP := 1" line and adjust the
defkeymap.map in that same directory (/usr/src/linux/drivers/char) to your
liking.

I have always done that. It worked through any kernel in the 2.6.18 series, but
does not work at all for any 2.6.19 or later kernel. It fails thusly:

  CC      drivers/char/random.o
  CC      drivers/char/tty_io.o

You were right, this was a bug. We sent a patch to fix this upstream and it's
made it into 2.6.23. Gentoo-sources-2.6.23 is in portage as of today.
