Using the lustre RPM's form sun's website.
It's a problem with the fact that Lustre kernels for RHEL4 are packaged the SuSE way, with a /usr/src/linux-$VERSION-$RELEASE/ and a /usr/src/linux-$VERSION-$RELEASE-obj/$ARCH/$FLAVOR/ directory holding the object files. Whereas RHEL4 expects everything to be located in /usr/src/linux-$VERSION-$RELEASE/. A workaround this is to put the .config file into the kernel sources directory, and prepare the kernel tree manually. What I usually do is the following (this is for Lustre 1.6.5.1): # rm /lib/modules/2.6.9-67.0.7.EL_lustre.1.6.5.1smp/build # ln -s /usr/src/linux-2.6.9-67.0.7.EL_lustre.1.6.5.1 /lib/modules/2.6.9-67.0.7.EL_lustre.1.6.5.1smp/build # cp /usr/src/linux-2.6.9-67.0.7.EL_lustre.1.6.5.1-obj/x86_64/smp/.config /usr/src/linux-2.6.9-67.0.7.EL_lustre.1.6.5.1/ # cd /usr/src/linux-2.6.9-67.0.7.EL_lustre.1.6.5.1/ # [edit Makefile, and replace 'custom' by 'smp' in EXTRAVERSION] # make oldconfig # make modules_prepare And then, you should be able to compile any additional kernel module. > The next problem I am stuck on is: > > In file included from mppLnx26_spinlock_size.c:51: > /usr/include/linux/autoconf.h:1:2: #error Invalid kernel header > included in userspace > mppLnx26_spinlock_size.c: In function `main': > mppLnx26_spinlock_size.c:102: error: `spinlock_t' undeclared (first > use in this function) Can't be sure it will fix this problem too, but it may be worth a try.
