Thanks Rob,

Hello Rob,

Thanks for your attention.

Here is the information about the system:

Linux Kernel version: 2.4.20-28.8SMP
CPU type: Intel Xeon 2.4 GHz (dual cpu system)
PVFS version 1.6.2
 

Build script for building pvfs:
================================
#!/bin/bash

# build pvfs (non-kernel stuff)

here=`pwd`

tgt=/u/systems/pvfs

pkg=pvfs-1.6.2

rm -rf $pkg
tar -xvzf $pkg.tgz

cd $pkg

./configure --prefix=/u/systems/pvfs
make
make install
==========================================

Build script for kernel module:
===========================================
#!/bin/bash

# build pvfs kernel module (after non-kernel stuff)

here=`pwd`

tgt=/u/systems/pvfs

pkg=pvfs-kernel-1.6.2-linux-2.4

rm -rf $pkg
tar -xvzf $pkg.tgz

mkdir -p $tgt/kernel

cd $pkg

./configure --prefix=/u/systems/pvfs --with-pvfs=/u/systems/pvfs
--with-moddir=/u/systems/pvfs/kernel
--with-kernel-headers=/usr/src/linux-2.4/include
make
make install
=======================

It used gcc compiler for building the kernel module and pvfs binaries.

Thanks again,

Hi,

What can you tell me about the machine:
- kernel version
- CPU type
- PVFS version
- options?

Thanks,

Rob
