[Linuxwacom-discuss] Building linuxwacom on Debian with 2.6.x kernel

[Steve W <s....@ve...>]

Ping and Debian fans,
Here is the write-up I promised earlier this week.  I wanted to wait until I
had the tools, particularly wacomcpl up and running before I published.  I also
wanted to make sure things actually worked, so I rebuilt everything from
scratch using these steps, but I may have missed some things.  I encourage
comments and suggestions.  Hope this is helpful.

-----------------------------------------------------------------------
Procedure for building linuxwacom package on Debian Sid/unstable 
with a 2.6 series kernel.  These instructions are current as of
May 28, 2004.  I have not tested on straight Debian Sarge/testing but it
should work there as well.  Note that the process required to build 
against a 2.4 series kernel is different and not described here.  Also,
note that most of these steps as written require root privilege.  There
are better ways of doing most of this (eg. fakeroot) but I wanted to keep
it simple.

1) Get development libraries needed for tools.  The libncurses, tcl, tk, libgtk
and libx11 development libraries are needed to build the tools.  The versions
shown below were current at the time of this writing.  At the moment libgtk is
only needed for xidump, on my system it pulled in six other development
libraries so if you don't need xidump you might consider leaving out
libgtk-dev.

apt-get install libncurses5-dev tcl8.4-dev tk8.4-dev libgtk2.0-dev libx11-dev

2) Get kernel source and build tools.  Unpack source.

apt-get install kernel-package kernel-source-2.6.6
cd /usr/src
tar -xjvf kernel-source-2.6.6.tar.bz2
ln -s kernel-source-2.6.6 linux
cd /usr/src/linux

3) Configure kernel.  I used the existing stock kernel configuration 
but feel free to configure your own.  Using the --revision switch is 
suggested but not required.  See /usr/share/doc/kernel-package/README.gz
for more information.  Note that running "make-kpkg configure" is 
required at this point because it creates the .../include/linux/version.h
file need by linuxwacom configure.

cp /boot/config-2.6.6-1-686 .config
make-kpkg --revision myhost.1 configure

4) Set up links to Tcl and Tk.  The naming structure expected by 
linuxwacom does not match Debian's unique layout.  I put these links in
/root but they can go anywhere.  Note that this is only required to 
build the wacomcpl tool.  Be sure to link to the library versions you 
actually installed in step one above.

cd /root 
mkdir tcl
cd /root/tcl
ln -s /usr/include/tcl8.4 include
mkdir lib
cd /root/tcl/lib
ln -s /usr/lib/libtcl8.4.so.0 libtcl8.4.so.0
ln -s /usr/lib/libtk8.4.so.0 libtk.so.0

5) Download the current linuxwacom package from 
http://linuxwacom.sourceforge.net.  I used the now current 0.6.3 version.
Unpack the archive somewhere convenient I chose /home/steve/wacom.

cd /home/steve/wacom
tar -xjvf ../linuxwacom-0.6.3.tar.bz2 
cd linuxwacom-0.6.3

6) Run configure to check your system and copy the module sources into 
the kernel source tree.  If you set up the /usr/src/linux link in step 2
above you are fine, otherwise add --with-kernel option.

./configure --with-tcl=/root/tcl --enable-wacom --enable-hid \
 --enable-usbmouse --enable-evdev --enable-mousedev

7) Build your new kernel.  This builds the entire kernel and all modules
specified in your .config file, so it may take a while.  I am using
initrd here, but if you configure your own smaller kernel that is not 
required.

cd /usr/src/linux
make-kpkg --initrd --revision myhost.1 kernel_image

8) Install your new kernel.

cd /usr/src
dpkg -i kernel-image-2.6.6_myhost.1_i386.deb

9) Build and install linuxwacom tools.

cd /home/steve/wacom/linuxwacom-0.6.3/
make
make install

10) Manually install the correct wacom_drv.o for your version of X11 and
kernel.

cp prebuilt/wacom_drv.o_4.3k2.6 /usr/X11R6/lib/modules/input/wacom_drv.o

11) Edit your XF86Config-4 file as desribed in the linuxwacom Howto.  Note
that if you have any unused input devices in your XF86Config-4 file they 
must have a one word identifer or wacomcpl may not work.  I had to delete
the unused "Configured Mouse" section from my file.  Reboot.  Enjoy.
