Bug 194903 – sys-kernel/gentoo-sources-2.6.22-r8 fails to compile

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description ta2002 2007-10-06 12:37:27 UTC]

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.

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:

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.
