[Pvfs2-users] Kernel Module - Compilation error

[Peng Gu]

My systems are installed with FC5 official release. On my systems, "#
uname -r " says 2.6.15-1.2054_FC5smp. With this in mind, I installed
the corresponding kernel source using "rpm -ivh
kernel-smp-devel-2.6.15-1.2054_FC5.i686.rpm".

And then I created a link to it:
# ln -s /usr/src/kernels/2.6.15-1.2054_FC5-smp-i686  /usr/src/kernels/linux-2.6

At this point, I ran the pvfs2 configure tool
#./configure --with-kernel=/usr/src/kernels/linux-2.6

After all these steps,  insmod still complains:

#insmod src/kernel/linux-2.6/pvfs2.ko
insmod: error inserting
'/usr/src/pvfs2/src/kernel/linux-2.6/pvfs2.ko': -1 Unknown symbol in
module

And here is the related message from "# dmesg":
pvfs2: Unknown symbol update_atime

The good news is that: the insmod problem disappears when I build the cvs tree.
The PVFS2 version string was 1.4.1pre1-2006-05-15-212716.

Thanks,
Peng
