    -lEGL

    I just did a clean build but with -lEGL appended to line 316 of the Makefile (added to CLIENT_LIBS) but I'm getting the same error as before.

    Working Panda ES apps

    Hi Oliver!

    Out of date? Why I'll hear no such thing! How very dare you suggest it!

    Nope, my drivers and system is updated daily and I had (have) the very latest OMAP PPA release drivers installed but yes, TI admit and we know for sure there are still bugs to be stamped out yet.

    If you have some demo program with source code (just something that will bring up an OpenGL ES2 rendering context on the device) then I can have a look and compare it with my implementation. It's also quite possible that I have bugs in that the GL context initialization code.

    P.S. It's probably better to use Phoronix's forums attachment mechanism for log files etc. Blogger doesn't offer this, unfortunately. (Don't worry, I get an email notification when you reply here.)
    Hold on, ES2? Your Maemo Q3 port was linking and I'm linking against the ES1 libs here so I presume you saying ES2 was a typo and you meant ES1 right?

    I can only currently give 1 working example of both ES1 and ES2 on Pandaboard:

    ES1 - dxx-rebirth works if I start it in windowed mode then switch to fullscreen after startup:

    http://www.dxx-rebirth.com/frm/index...ic,1500.0.html

    ES2 - I've not tried DarkPlaces or its required new SDL yet but I have glmark2-es2 from the Ubuntu repos running fine on my Panda

    What log files would you like to see?

    Thanks. There is a PayPal donate button on my blog.

    The discrepancy between -lGLES_CM and -lGLESv1_CM can be blamed on Imagination Technologies' driver.

    I saw the Quake 3 error you posted on my blog,
    PVRWarning): PVRSRVOpenDCDevice: Warning - 138 returned [95, /bridged_pvr_dc_glue.c]

    openarena - same error

    Hi curaga!

    Trying openarena was a good idea so thats what I did but I get the same error as when I tried rq3 so I suspect I'll get the same error again if I try the official Q3 pak files. I have pasted the full error on Olivers blog again.

    The command I tried to start ioquake3 with openarena (as pulled from the Precise repos) was:

    ./ioquake3.armv7l +set fs_basepath /usr/share/games/openarena +set fs_game baseoa +set r_fullscreen 0

    You can always use OpenArena paks; though you won't be able to play online with a generic ioq3 engine I believe.

    correction

    I thought we could edit posts on this forum after they've been posted? I'm logged in but I can't see any 'Edit' buttons on my posts here.

    I was hoping to edit my previous post to correct myself as I do of course know of 2 open source Linux games that support GLES2 - idtech4 and DP - but I don't count idtech4 as a real possibility for my Pandaboard and its not ready yet either.

    EDIT (you can!)

    Now I see an edit button on this post but not my older posts so I'm guessing posts on here get locked after a number of hours unless this is a weird bug in 12.04 armhf FF? Why lock older posts Michael (if thats what is happening)?

    Maemo Q3 compiled!

    Don't you just love responsive devs? I do!

    I have some good news for fellow Pandaboardians (first use?) as I have successfully compiled Oliver's Maemo Q3 port on the Panda now. Maybe it'd run if I got hold of the official Q3 pak files but I don't have them at the mo so I'm trying to get it running with rq3 first but not having much luck. If you want to see the errors I get they're pasted in the comments section of Olivers latest blog posting linked above.

    If anyone else wants to compile Olivers Maemo Q3 port on their Pandaboard, all you have to do is change 'arm' on line 297 of the Makefile to 'armv7l' and on line 316 change -lGLES_CM to -lGLESv1_CM - thats it!

    I've also heard back from Lord Havoc aka the DarkPlaces dev who informs me that to compile DP with GLES support you have to use libSDL2 for this (get the snapshot or hg from http://libsdl.org ) and define USE_GLES2 when compiling. I was happy to hear that DP uses GLES2 because I don't know of a single other open source Linux game with support for GLES2.

    idtech4 on Panda

    I'm never expecting to play Doom 3 at a decent framerate on my Pandaboard but I noticed Oliver has pushed his GL ES2 idtech4 code to github recently so I thought I'd at least try building it just for the craic. Build failed but I'm not surprised or really that bothered as I don't have a copy of Doom 3 to test it with even if it did build.

    DarkPlace GLES will bring us Quake and Nexuiz whilst a GLES ioq3 port such as Olivers will bring Q3, reaction Q3, Smokin' Guns etc and both these engines should run at a decent rate on the Panda as soon as we have a GLES optimzed version working.
