[Pvfs2-users] configure: error: The kernel source tree must have been configured.

[Phil Carns]

Hi Amit,

I think the output of those commands tells us the problem.  You are 
running kernel version 2.6.9-42.0.2.EL, but the only kernel-smp-devel 
package that you have installed is 2.6.9-42.0.10.EL.

That needs to be resolved by one of the following options:

a) switching which kernel you are running to 2.6.9-42.0.10.EL to match 
your kernel-smp-devel package
b) installing kernel-smp-devel-2.6.9-42.0.2.EL to match the kernel you 
are running

The a) option is probably the best choice since it looks like you have 
the right packages installed for it anyway; your machine is just booted 
into the older kernel for some reason.  I don't recall how redhat 
handles its kernels, but it may be that you just need to reboot the box 
and you it will automatically come up with the 0.10 one.  Otherwise you 
would need to adjust your grub configuration to tell it to boot with the 
0.10 one.

At any rate, once you have the output of "uname -r" matching one of the 
results of "rpm -q kernel-smp-devel" then you should be all set to 
configure pvfs.
