13.7 - Building wacom driver On RHEL 5 / CentOS 5

Summary

When installing a driver,  you will not always get an rpm package to install it. You may have to 
compile it for the  kernel and  architecture  you are using.  This document will show you how to 
compile the wacom driver from source.

Download the binaries

You will need to download the source for the wacom driver. You need to go on the linux wacom web 
page: http://linuxwacom.sourceforge.net. In this example, you download it into /usr/tmp.

Uncompress the binaries

Once downloaded,  the wacom driver source package are TARed and compressed as bz2 archives. They 
must extracted and uncompressed unsing the following commands.

      su - root
      cd /usr/tmp
      tar xjvf linuxwacom-0.8.4.tar.bz2

Note: tar options: x=extract;  j=extract bz2  before tar; v=verbose; f=the file you are going to 
uncompress.

Updating/installing pre-requisite packages with yum before compiling

Before compiling the driver for your workstation, you need to be sure to have some pre-requisites 
modules installed. The easiest way to install them is by using yum.

This utility allows you to automatically  download and install the kernel headers and development 
package,  the X server  software  development  kit and  source,  as well as the libXi development 
package. (Note: Your workstation must have internet access).

      yum install kernel-devel kernel-headers 
      yum install xorg-x11-server-source xorg-x11-server-sdk libXi-devel

Once yum found everything it needs, press "y" to begin the installation process.

Compiling the driver

   1. Compiling the driver is simple.  You need to configure a custom installer, create it,  and 
install it. Type the following commands:
       
      su - root
      cd /usr/tmp/linuxwacom-0.8.4
      ./configure --enable-wacom
       
If some dependencies aren't resolved, the configure step will not be completed successfully. Once 
dependancies are resolved, run ./configure again.
       
   2. When the "configure" step succeeds, continue to the next steps. Type:
       
      ./make
       
   3. This will create the actual installer using the configuration from the previous step. Type:
       
      ./make install
       
      This will install the driver.
       
   4. Install kernel driver (create a backup copy)
 
      cp /lib/modules/`uname -r`/kernel/drivers/usb/input/wacom.ko  /lib/modules/`uname -r`/kernel/drivers/usb/input/wacom.ko.old.$$
      cp src/`uname -r | cut -d- -f1`/wacom.ko /lib/modules/`uname -r`/kernel/drivers/usb/input/

   5. Reboot the workstation
