[Pvfs2-users] Problem with compiling the PVFS2 Linux Kernel Interface

Thu, 15 Apr 2010 10:03:07 -0700 

Hi,

I'm a PVFS2 newbie and today a tried to install PVFS2 for the first time inside 
Amazon EC2. I used the Quick Start Guide which is very helpful.

The compilation and configuration of server and client were successful. The 
server is working and I can access it with pvfs2-ping, pvfs2-ls and pvfs2-cp.

The problem: When I try to compile the kernel module I have an error message. 

# uname -a
Linux ip-10-245-202-160 2.6.32-305-ec2 #9~pre1 SMP Wed Apr 14 12:27:39 UTC 2010

# cd /usr/src/pvfs2
# ./configure --with-kernel=/lib/modules/`uname -r`/build
