This document describes building an OLPC kernel from the olpc-2.6 git repository or SRPM. |
|||
== The OLPC kernel git repository == |
|||
The OLPC kernel git repository can be checked out with the following command: |
|||
<pre> |
|||
git clone git://dev.laptop.org/olpc-2.6 |
|||
</pre> |
|||
Alternatively, SRPMs are available at |
|||
http://dev.laptop.org/~dilinger/rpms/ |
|||
The SRPM will place sources in /usr/src/redhat/SOURCES/olpc-2.6.tar.bz2 |
|||
== Building the git repository == |
|||
After doing a checkout, one can build the git repository using the standard linux build process (ie, make config; make; make install). The recommended default config file is in the root of the git repository (.config). |
|||
== Building the RPM == |
|||
Building the RPM involves downloading the SRPM, installing it, and then running the rpmbuild command. The "dist" and "olpc" macros should be defined when building: |
|||
<pre> |
|||
# rpm -ivh kernel-2.6.1*-20061026_dc5079fafb767e4olpc1.src.rpm |
|||
# rpmbuild -ba --define "dist olpc1" --define "olpc 1" --target=i586 /usr/src/redhat/SPECS/olpc-2.6.spec |
|||
</pre> |
|||
After the build finishes, the newly build RPMs will be in /usr/src/redhat/RPMS, and the build tree that was used will be in /usr/src/redhat/BUILD. To make quick changes to the source (for testing purposes), you can: |
|||
<pre> |
|||
# cd /usr/src/redhat/BUILD/kernel-2.6.18/linux-2.6.18.i586 |
|||
# patch -p1 < ~/somefix.patch |
|||
# make |
|||
# scp drivers/video/geode/gxfb_dcon.ko testboard: |
|||
# ssh testboard "rmmod gxfb_dcon; insmod ./gxfb_dcon.ko" |
|||
</pre> |
