I’m in the process of doing an analysis of the Matchbox code to determine what needs to change in it to create BUI.\u00a0 So far I’ve mapped out the basic code flow<\/a> and identified the purposes of the files within the window manager, which is where I’m starting the analysis.\u00a0 Yesterday I experimented (lightly) with some changes to see if I could identify where the wm resized clients when the panel opened and closed.\u00a0 I found it in <\/span>dockbar_client.c:dockbar_client_show()<\/em><\/span> which calls wm_update_layout()<\/em><\/span>. \u00a0 While this code is associated with that resizing, just commenting out portions of it is not sufficient.\u00a0 If I do that, the client gets resized too large.\u00a0 So this is just the start of changing that resize handling process.<\/p>\n

I also made a release of BUI 0.1<\/a> yesterday on SourceForge.\u00a0 That’s just the original Matchbox code in a build environment.\u00a0 It includes a target for testing the code under Xephyr too.\u00a0 No changes to Matchbox yet, however.\u00a0 It’s just a starting point for anyone interested in diving into this with me.<\/p>\n

While working on the Matchbox analysis I ran the BeagleBox build for the beagleboard hardware.\u00a0 This differs from the qemu build in that the Cortex-A8 compiler is built instead of the A7 compiler.\u00a0 In doing this I found a number of problems with that part of the build.\u00a0 First, the A8 compiler was not getting built the way I thought it would.\u00a0 I have to keep separate config files in the BeagleBox source tree specific to how I want to build the compiler due to the way I’m building it (not because of any kind of limitations in Crosstool-NG<\/a> – the issue is in how I’m building the BeagleBox tree).\u00a0 Once that was fixed I updated the kernel build to the latest kernel being built by OE’s OMAP builds, which is kernel 2.6.32 from the tmlind git repository.\u00a0 Then I migrated in the xterm and surf updates to the buildroot.\u00a0 So now the beagleboard build should be up to date as much as possible.\u00a0 I can’t test it yet since I don’t have a BeagleBoard.\u00a0 I expect to make that purchase in mid\/late September.\u00a0 Note that Crosstool-NG recently rev’d their release.\u00a0 I have not rev’d my build to use the new release.\u00a0 I’ll look at that later (added a Flyspray entry to cover it).<\/p>\n

In the mean time I continue work on BUI and integration of the SGX components to the BeagleBoard build.\u00a0 Anyone interested in joining in should take a look at the Flyspray<\/a> list of tasks to see what you might be interested in working on.<\/p>\n","protected":false},"excerpt":{"rendered":"
