Build Environment Ubuntu 9.04

2009-04-11T18:12:20Z

Sax1johno: Changed the build instructions to include instructions for using Ubuntu on the host computer.

This the current set-up for Ubuntu 8.10 with file modifications as described [http://www.nabble.com/Ubuntu-8.10-and-Open-Embeded-td21136352.html on this thread]. gumstix-oe version is 318.

== Setup Build Environment ==
1) Get Ubuntu linux 8.10, and install it on your computer; you can install a vmware version of Ubuntu too, but it will be slow during the building process.

Reconfigure sh to point to bash, not dash:

sudo dpkg-reconfigure dash

Answer no when asked whether you want to install dash as /bin/sh.

2) Install (build-essential, help2man, diffstat, texi2html, texinfo, libncurses5-dev, cvs, gawk, python-dev, python-pysqlite2, python-psyco, ckermit, lrzsz, subversion) by using apt-get. i.e:
sudo apt-get install build-essential help2man diffstat texi2html texinfo libncurses5-dev cvs gawk python-dev python-pysqlite2 python-psyco ckermit lrzsz subversion

3) Download the source from svn, caching the source code
mkdir ~/gumstix
cd ~/gumstix
<nowiki>svn co https://gumstix.svn.sourceforge.net/svnroot/gumstix/trunk gumstix-oe</nowiki>
cat gumstix-oe/extras/profile >> ~/.bashrc
sudo groupadd oe
sudo usermod -a -G oe YOUR_CURRENT_USERNAME
sudo mkdir /usr/share/sources
sudo chgrp oe /usr/share/sources
sudo chmod 0775 /usr/share/sources
sudo chmod ug+s /usr/share/sources

4) Downgrade to gcc-4.1 and g++-4.1 and change the links:

sudo aptitude install gcc-4.1 g++-4.1
sudo ln -sf /usr/bin/gcc-4.1 /usr/bin/gcc
sudo ln -sf /usr/bin/g++-4.1 /usr/bin/g++

Check the links are correct using:

ls -l /usr/bin/gcc
ls -l /usr/bin/g++

5) Log out and log in again.

6) Build the basic image, it will fail with an error in dbus:

bitbake gumstix-basic-image

Edit <code>gumstix/gumstix-oe/tmp/work/i686-linux/dbus-native-1.0.1-r0/dbus-1.0.1/dbus/dbus-sysdeps-unix.c</code>

Add this struct,

<code><pre>
struct ucred {
unsigned int pid;
unsigned int uid;
unsigned int gid;
};
</pre></code>

after the macros.

7) Build the basic image, it will fail with an error in sumversion:

bitbake gumstix-basic-image

Edit <code>gumstix/gumstix-oe/tmp/work/gumstix-custom-verdex-angstrom-linux-gnueabi/gumstix-kernel-2.6.21-r1/linux-2.6.21/scripts/mod/sumversion.c</code>

Add this line,

#include <limits.h>

after all of the other includes.

8) Build the basic image again, this time it should work:

bitbake gumstix-basic-image

9) If everything builds ok, it could be a good idea to modify the dbus-sysdeps-unix.c and sumversion.c files is their respective packages in /usr/share/sources as otherwise everytime you do a rebuild they will be wiped.

Installing Ubuntu 9.04 on Gumstix Overo

2009-04-11T18:01:49Z

Sax1johno: Moved the build environment notes to here, and removed the previous article.

For some installation instructions for Ubuntu on the Gumstix Overo, [http://johnwoconnor.blogspot.com/2009/04/installing-ubuntu-on-gumstix-overo.html click here]. It's a mashup of some other tutorials that results in a working installation of Ubuntu 9.04.

Also, the [http://johnwoconnor.blogspot.com/2009/04/ubuntu-904-on-gumstick.html previous post] has some images. Video to come.
