-== Setup Build Environment ==
-) 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.
-) 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
-) 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
-) 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++
-) Log out and log in again.
-) 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.
-) 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.
-) Build the basic image again, this time it should work:
- bitbake gumstix-basic-image
-) 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.
