Time and time again I have failed today, trying to insert the pvfs2.ko
module into the kernel. I've spent hours upon hours debugging the problem
to no avail.
EXECUTIVE SUMMARY
Trying to install pvfs2 on ibm zSeries x86 architecture. It compiles fine.
Main problem is that my kernel was compiled with gcc 4.0 and I currently
have gcc 4.1 installed. Due to package dependencies on this Debian Linux
machine, I'm unable to downgrade to 4.0 without a huge amount of pain and
heartache. Neither am I able to upgrade to a new kernel at this time.
DETAILS
I've tried setting the CC environment variable to compile with `cc -V 4.0`
via `export CC="/usr/bin/cc -V 4.0"`. That makes its way into my Makefile
and I'm assuming the source code is compiling with that 4.0 directive. I
apply the pvfs-lk21.patch to the build tree, and then I go ahead and compile
with:
./configure -with-mpi=/usr/bin/mpirun
-with-kernel=/usr/src/linux-source-2.6.15/
make
make install
make kmod_install
However when I try to insert the module using either insmod or modprobe I
encounter errors.
With insmod:
insmod /usr/src/pvfs2/src/kernel/linux-2.6/pvfs2.ko
insmod: error inserting '/usr/src/pvfs2/src/kernel/linux-
2.6/pvfs2.ko': -1 Invalid module format
dmesg|tail -n1
pvfs2: version magic '2.6.15 486 gcc-4.1' should be '2.6.15-1-486 486
gcc-4.0'
With modprobe (trying to force the module in, despite bad vermagic):
modprobe -i --force-vermagic pvfs2
FATAL: Module pvfs2 not found.
modprobe -i --force-vermagic
/usr/src/pvfs2/src/kernel/linux-2.6/pvfs2.ko
FATAL: Module /usr/src/pvfs2/src/kernel/linux_2.6/pvfs2.ko
not found.
CONCLUSION
Am I a doomed man? What am I doing wrong? How can I fix this? I thank in
advance any and everyone who helps me to solve this problem.
what flavor of debian is this? etch? lenny? sarge?
I don't know any version of debian currently with a 2.6.15 kernel if
its a custom kernel (built in house?) then you should get your hands
on the source and rebuild it for the new compiler so this doesn't come
up again.
also the --force-vermagic only refers to the kernel version (iirc) not
the gcc version. The gcc version is a must to get right sort of thing
with the kernel.
