[ofa-general] ofed kernel config.mk / BACKPORT_INCLUDES

[Guy Coates]

Hi Brian;

A fresh build of the ofa-kernel package gives the following in the build dir:


cat config.mk
BACKPORT_INCLUDES=-I${CWD}/kernel_addons/backport/2.6.22/include/

That is obviously wrong.


If I run the lustre configure, I get:


./configure --with-o2ib=/usr/src/modules/ofa-kernel
--with-linux=/scratch/linux-2.6.22.19

<snip>
checking whether to enable OpenIB gen2 support... no
configure: error: can't compile with OpenIB gen2 headers under
/usr/src/modules/ofa-kernel


config.log has the following set for LNET_INCLUDES:


EXTRA_LNET_INCLUDE='-I-I/kernel_addons/backport/2.6.22/include/
-I/usr/src/modules/ofa-kernel/include'


which results in:

configure:6885: cp conftest.c build && make -d modules  CC=gcc -f
/tmp/lustre-1.8.1/build/Makefile
LUSTRE_LINUX_CONFIG=/scratch/linux-2.6.22.19/.config

If I fix config.mk so that the correct path is present:


cat config.mk
BACKPORT_INCLUDES=-I/usr/src/modules/kernel_addons/backport/2.6.22/include/

configure still fails with:

checking whether to enable OpenIB gen2 support... no
configure: error: can't compile with OpenIB gen2 headers under
/usr/src/modules/ofa-kernel

config.log has the following incorrect EXTRA_LNET_INCLUDE:

EXTRA_LNET_INCLUDE='-I-I/usr/src/modules/kernel_addons/backport/2.6.22/include/
 -I/usr/src/modules/ofa-kernel/include'


With the two patches previously sent, everything builds (modulo a separate bug
in the OFED 2.6.22 backport includes).

Cheers,

Guy
