Bug 432346 – sys-fs/aufs3-3_p20120813 does not build with KBUILD_OUTPUT: Makefile:10: could not find kernel config file. internal auto-config may fail

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Dennis Schridde 2012-08-22 20:14:04 UTC]

# export KERNEL_DIR=/usr/src/linux-3.5.2-gentoo KBUILD_OUTPUT=/root/build-3.5.2-gentoo

>>> Compiling source in /var/tmp/portage/sys-fs/aufs3-3_p20120813/work/aufs3-standalone ...
make CC=powerpc64-unknown-linux-gnu-gcc CONFIG_AUFS_FS=m KDIR=/usr/src/linux-3.5.2-gentoo

config.mk:55: CONFIG_AUFS_SBILIST is enabled but CONFIG_AUFS_MAGIC_SYSRQ nor CONFIG_PROC_FS
config.mk:66: *** CONFIG_AUFS_HFSNOTIFY requires CONFIG_FSNOTIFY.  Stop.

.config is located in the build dir, not the source dir. Hence it should be KDIR=$KBUILD_OUTPUT.

[Comment 1 Justin Lecher (RETIRED) 2012-08-23 06:42:38 UTC]

could you please do this without setting Kernel_DIR and KBUILD_OUTPUT? Most properly this is the problem. Can't test it right now, but I will take a look on it at the weekend.

[Comment 2 Dennis Schridde 2012-08-23 07:09:49 UTC]

If you look at the Makefile, it also sets KDIR=/lib/modules/…/build. So it should be KDIR=$KV_OUT_DIR instead of KDIR=$KV_DIR, imo.

I assume that would work, if I did compile my kernel in-source, yes.

I think this issue is still present:
emake CC=$(tc-getCC) LD=$(tc-getLD) LDFLAGS="$(raw-ldflags)" ARCH=$(tc-arch-kernel) CONFIG_AUFS_FS=m KDIR=${KV_DIR}

This should be KV_OUT_DIR, right?
