Creating articles in the wiki is a collaborative process, at any point, if you see a mistake you can contribute to this article. Please, use the discussion tab for user comments.

It is possible trunk can suffer temporary periods of instability while new features are developed and if this is undesirable we recommend using one of the release branches. '''Use ONLY for development purposes.'''</span> GeeXboX and OpenBricks use Mercurial as a revision control system, so you will install the mercurial package for your host system. On an Ubuntu-based system this will be done with, $ sudo apt-get install mercurial Now, the first thing you will do is download the sources from Mercurial OpenBricks repository (which is where bleeding-edge GeeXboX development is done). $ hg clone http://hg.openbricks.org/openbricks Next, configure OpenBrics to build a GeeXboX image for the OMAP3 platform. Run $ make menuconfig and set Flavour -> GeeXboX General Setup -> Target architecture (arm) -> Target sub-architecture (ARMv7 / Cortex) -> Target platform (OMAP3) -> Target CPU (cortex-a8) -> FPU optimizations (NEON) Settings -> Target Images -> Flat root Features -> Audio -> deselect PulseAudio (recommended, for now PulseAudio has been tested only on x86) If you want to enable OpenGL|ES acceleration set Features -> Enable non-free components Features -> Hardware Accelerators -> EGL -> OpenGL -> OpenGL|ES -> OpenVG -> EGL provider (SGX) -> OpenGL|ES provider (SGX) -> OpenVG provider (SGX) If you want to enable OpenMAX acceleration set Features -> Enable non-free components Features -> Hardware Accelerators -> OpenMAX -> OpenMAX provider (TI OpenMAX IL) If you want to enable TI DSP acceleration (lightweigth alternative to OpenMAX for DSP acceleration) Features -> Enable non-free components Features -> Hardware Accelerators -> TI C64x DSP Optionally select other features or packages you may need. Exit and save the configuration, then build with $ make The resulting rootfs will be placed in the binaries directory directory == Make a bootable MMC card with GeeXbox == First prepare the SD card the following way:* create one boot FAT32 (type 0B) partition, any size, I took 8MB* create one rootfs EXT2 partition. Then copy the uImage and boot.ini files to FAT32 partition (paths relative to the rootfs location) $ cp boot/boot.ini /media/boot $ cp boot/uImage /media/boot Finally, copy the rootfs contents to EXT2 partition (paths relative to the rootfs location) $ fakeroot cp -dpfa -R * /media/rootfs/ With default environment the IGEP v2 detects the boot.ini script which contains all the necessary instructions for the OS to auto-boot. == Annex: Known issues and solutions == === gzip: stdin: invalid compressed data--crc error === Error : UNPACK expat gzip: stdin: invalid compressed data--crc error tar: Child returned status 1 tar: Exiting with failure status due to previous errors make: *** [flat] Error 2 Use gzrecover to recover the expat file $ gzrecover sources/expat/expat-2.0.1.tar.gz $ mv expat-2.0.1.tar.recovered expat-2.0.1.tar $ gzip expat-2.0.1.tar $ mv expat-2.0.1.tar.gz sources/expat/ Distributions affected: * Ubuntu 10.04 LTS (Lucid Lynx) - (https://bugs.launchpad.net/ubuntu/+source/gzip/+bug/524366) [[Category:Software distributions|GeexboxGeeXboX]]
