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.
