[Lustre-discuss] build and install lustre from source code -- warning on livcfs.ko for no modversions

[Weilin Chang]

There is a warning message while doing "make SUBDIRS=scripts". Is there anything missing? Is there a way to work around the problem?

Subject: build and install lustre from source code -- warning on livcfs.ko for no modversions

I built and installed Lustre from source. When I installed built luster-modules- RPM, I got libcfs.ko from the kernel-2.6.18-prep has no modversions (the message is posted below), so it cannot be reused for kernel. Is there any procedure I need to do during the build? There is include/config/modversion.h under patched kernel, but the file does not have any contens and its size is 0.

Thanks for your help.

Here were messages when I installed RPM:
