SMSC 7500 device driver - unable to build on 2.6.32-4-pve

[frankin]

Hi. I have a pve-based kernel modules build issue. I apologize in advance for an extra long post.
I am trying to get a SMSC7500 USB Ethernet dongle to be recognized by a Linux Proxmox host, but it doesn't initialize the device because the module is not available.

I installed RedHat Fedora 14 32-bit version and the driver initialized automatically when I plugged the device in. works fine. no issues.
I installed RedHat Fedora 17 AMD64(64-bit) version and the driver initialized automatically when I plugged the device in. works fine. no issues.

Installed a fully clean iso image of Debian 5.0.9 64-bit version and the USB device is recognized by the system, but doesn't load a driver module automatically.

su
apt-get install build-essential
apt-get install linux-headers-2.6.26-2-amd64
make
cp smsc7500.ko /lib/modules/2.6.26-2-amd64/kernel/drivers/net/usb/
chmod 644 /lib/modules/2.6.26-2-amd64/kernel/drivers/net/usb/smsc7500.ko
insmod /lib/modules/2.6.26-2-amd64/kernel/drivers/net/usb/smsc7500.ko

I got a kernel fault, but device initializes as 1000 (Gb) in ifconfig -a and appears to work fine.
Debian 5.09 kernel version is 2.6.26-2... the version of Debian-Proxmox I am running is very close to this Linux flavor/version.

Now back to my actual issue:

This machine is on a closed network, without internet access. I installed the following packages to build my driver (running as root):

pve-headers-2.6.32-4-pve_2.6.32-33_amd64.deb

If I run make on the smsc7500 source, I get a compile error:

masterhost2:~/starTechDriver# ls

make[1]: *** No rule to make target `modules'. Stop.
make[1]: Leaving directory `/lib/modules/2.6.32-4-pve/build'
make: *** [modules] Error 2

From inspecting the significant differences between the kernel-source directories (/usr/src, /lib/modules) on the 2.6.32-4-pve and Debian-2.6.26-2 systems, it looks like part of the PVE kernel-source is missing.
That directory looks like this:

Does anyone have any advice to work towards building a module that will work for my PVE system?

Do I need something like this?:
ftp://download.proxmox.com/sources/pve-kernel-2.6.32_2011-09-21.tar.gz


Thanks in advance.

wrong forum, I will move it.

(cutting out lots of interim tasks and efforts for brevity)
I installed the 1.7 proxmox from the CD ISO image. This is 2.6.32-4-pve(the kernel I need to compile against to build the smsc7500.ko module).
Install the linux-headers, make, and it builds fine.
Insmod the module and I get a module_layout error. In short, the kernel version on my install is different than the kernel-source files under /lib/modules/`uname -r`.
grumble.

After that, I install the pve-kernel-source package and try to make all. Lots of errors/build-complaints to overcome. Then the make errors with a bounds.c file error. The module.symvers, Makefile, and bounds.c files all are present and seem fine.
I'm kind of stuck trying to correctly rebuild the kernel source, because I'm not sure what chicken and which egg to install first.

So, getting back to the original problem, I have a 2.6.32-4-pve system that needs a compatible device driver to be loaded as a kernel module for my USB ethernet device. It does not compile on my target system. On newer systems, including on the latest PVE version, it builds and insmods the module correctly. On a duplicate and similar system it builds fine, but doesn't insmod because the kernel source differs from the running kernel.
When I try to install compatible kernel source, linux-headers, and everything needed to build the kernel source for a 2.6.32-4-pve system, I run into complications that I don't know how to solve. Namely, I don't know how to build the right environment with the kernel.org 2.6.32-4 kernel source and the pve kernel source. Using just the pve kernel source, it doesn't want to do anything -- no make config or make mrproper or make prepare or make menuconfig or make -anything- except make all. I assume you don't need the 'public' version of 2.6.32-4 source at all, but the pve kernel source appears incomplete to me. I don't wish to rebuild the kernel, I wish to create the correct environment to build the smsc7500.ko module.
Please help, thanks.

you work on a very outdated system, but I assume you are aware of this.

for 1.7 repo, see http://download.proxmox.com/debian/dists/lenny/pve1.7/binary-amd64/

install the right pve-headers package and try again.
