Attempting to build comedi with module-assistant command
# m-a -t -v a-b comedi
yields the following error:
-----------------------------------------------------------
checking for Linux build in /lib/modules/2.6.29-1-amd64/build... yes
checking for separate Linux source and build directory... yes
checking for Linux source in /usr/src/linux-headers-2.6.29-1-common
O=/usr/src/linux-headers-2.6.29-1-amd64... not found
configure: error: Linux source directory not found
make[1]: *** [binary-modules] Error 1
make[1]: Leaving directory `/usr/src/modules/comedi'
make: *** [kdist_build] Error 2
BUILD FAILED!
-----------------------------------------------------------
This is happens because the configure script tries to extract the Linux source
directory with
dir=`sed -n -e 's/^MAKEARGS *:= *-C *\(.*\)/\1/p' "$LINUX_DIR/Makefile"`
from /usr/src/linux-headers-2.6.29-1-amd64/Makefile.
The MAKEARGS line in this file is
MAKEARGS := -C /usr/src/linux-headers-2.6.29-1-common
O=/usr/src/linux-headers-2.6.29-1-amd64
so configure sets
dir=/usr/src/linux-headers-2.6.29-1-common
O=/usr/src/linux-headers-2.6.29-1-amd64
and fails.
The attached patch fixes the build for me. Note that I'm no sed wizard so maybe
there is a more correct/robust way to fix things.
Probably something along these lines should also be applied upstream to
m4/as-linux.m4 where this test comes from. Although I guess the upcoming
integration of comedi into the kernel (at least staging as of 2.6.30) will soon
make this obsolete.
Thanks,
Jan
