Ubuntu Wiki

This page will hopefully evolve into a generic Howto, but for now it will focus on the acx wifi driver from http://acx100.sourceforge.net

I am working with the hawking_hwp54g – Ubuntu has and older version of the driver, and my card isn't working. So I thought I would try using the current version of the driver, and make some notes along the way.

Make a dir, get/untar the acx source.

mkdir -p src/acx
cd src/acx
wget http://www.cmartin.tk/acx/acx-20060521.tar.bz2
tar xjvf acx-20060521.tar.bz2

Warning! acx-20060521.tar.bz2 is a tar-bomb (drops files and dirs in the current dir instead of creating a single dir)

The Readme says I need to compile a new kernel, but that isn't true.

To build anything, you might as well get the basic build package, and to build a kernel module, you need the KernelHeaders (for the box the module will be running on)

sudo apt-get install build-essential linux-headers-`uname -r`

To build, don't follow the acx's Readme (it says you need to compile the whole kernel.) Following a lines I saw here: http://acx100.sourceforge.net/wiki/ACX

make -C /lib/modules/`uname -r`/build M=`pwd`
sudo make -C /lib/modules/`uname -r`/build M=`pwd` modules_install 

Thats about it for building and installing. In the case of the acx module, using it takes a few more steps, which are slightly off topic, but I may as well continue them here.

Attention! Probably it isn't work well with Ubuntu 5.10.

Trying to install the ACX111 driver I get the following errors:

from /usr/src/acx-20060215 calling

make -C /lib/modules/`uname -r`/build M=`pwd`

causes

• 1) the first message tells me that the directory build in /lib/modules/2.6.12-9-386/ doesn't exist.

OK! I try mkdir build to create the build-directory;

• 2) the second error is

make: Entering directory `/lib/modules/2.6.12-9-386/build'
make: *** No targets specified and no makefile found.   Stop.
make: Leaving directory `/lib/modules/2.6.12-9-386/build'

Do you have any idea?
