dkms build error mptlinux drivers

[dushy]

Hey,

I need to upgrade the default kernel of Redhat ES4 to 2.6.19.1
available from kernel.org. The system has 2 RAID controllers. Iam
having trouble getting the mptlinux driver to work.

system config is..

# lspci
08:02.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID (rev 01)
0c:08.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1068
PCI-X Fusion-MPT SAS (rev 01)

[root at db]# /usr/local/src/raid/omsa5/omsa5/linux/supportscripts/prereqcheck/sysreport
prereqcheck/sysreport
Libsmbios:    0.8.0
System ID:    0x01B8
Service Tag:  H5F89C1
Product Name: PowerEdge 1900
BIOS Version: 1.2.0
Vendor:       Dell Inc.
Is Dell:      1

[root at db]# uname -a
Linux db 2.6.9-42.0.3.ELsmp #1 SMP Mon Sep 25 17:24:31 EDT 2006 x86_64
x86_64 x86_64 GNU/Linux

Below are the steps i followed..

* Compiled & installed 2.6.19.1 kernel. Havent rebooted with the new
kernel yet as it doesnt have the drivers for the LSI SAS Fusion RAID
controller.
* downloaded the drivers from
http://ftp.us.dell.com/SAS-RAID/mptlinux-3.02.63-5.dkms.tgz
* Installed dkms-2.0.11-1.noarch.rpm and mptlinux-3.02.63-5dkms.noarch.rpm
* Driver docs mentions to perform below steps if kernel is upgraded

dkms build -m mptlinux -v <version> -k <kernel>
dkms install -m mptlinux -v <version> -k <kernel>
[ Doc is at : http://ftp1.us.dell.com/sas-raid/Rhel4_mptlinux_a02.txt]

* When i do a dkms build, i get the below error

[root at db src]# dkms build -m mptlinux -v 3.02.63 -k 2.6.19.1

Kernel preparation unnecessary for this kernel.  Skipping...

Error! Bad return status for module build on kernel: 2.6.19.1 (x86_64)
Consult the make.log in the build directory
/var/lib/dkms/mptlinux/3.02.63/build/ for more information.

* make.log has the below errors..

* I tried changing the make command in thi smodules dkms.conf to below
to use /usr/include as a include path but it did not help and i get
the same error.

CFLAGS=-I/usr/include make -C ${kernel_source_dir}
SUBDIRS=${dkms_tree}/${PACKAGE_NAME}/${PACKAGE_VERSION}/build modules

Earlier it was

make -C ${kernel_source_dir}
SUBDIRS=${dkms_tree}/${PACKAGE_NAME}/${PACKAGE_VERSION}/build modules

1. Am i following the right steps to get this module working with 2.6.19.1 ?
2. Will this driver work with non Redhat kernels ?

TIA and please let me know if any info is required.

Thanks
