Bug 42460 – error compiling linux-2.6.3-gentoo-r1 without CONFIG_SWAP=y

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Joel Metelius 2004-02-22 03:25:43 UTC]

Compile error from make:

mm/vmscan.c: In function `refill_inactive_zone':
mm/vmscan.c:649: error: `swapper_space' undeclared (first use in thisfunction)
mm/vmscan.c:649: error: (Each undeclared identifier is reported onlyonce
mm/vmscan.c:649: error: for each function it appears in.)
make[1]: *** [mm/vmscan.o] Error 1
make: *** [mm] Error 2

problem fixed by adding CONFIG_SWAP=y in .config

this problem only occurs when used with linux-2.6.0 headers.
Can you confirm your using 2.6.0 headers?
I shall look at this bug after my holiday.
Thanks for bugging :)

Patch

Nope, kernel headers don't have anything to do with the kernel - remember that
the kernel is the kernel-headers source so that would mean that the kernel is
broken in the end anyway.

Anyhow, this is caused by 425_am6-2.6.3.patch which isn't properly #ifdef
CONFIG_SWAP'ped like the rest of the vmscan.c file. Anyway, this patch on that
patch should work

this has been fixed in CVS and shall go mainstream sometime soon
