e17 with GL

Cam · 2005-06-21 07:47:22

Here's a PKGBUILD and patch I put together that'll build an e-CVS package that has Evas using it's OpenGL engine. It's nothing fancy, more info can be found here but it works quite well with my nvidia card. I'm writing this with the layered sky background running at full steam behind Firefox. The E17 modules support the transparency but Eterm doesn't at this stage and I don't know if it will but this isn't meant for full-time use, just to have a squiz.

For it to work, I use nickm's packages and it only requires a rebuild of e-CVS. Also, you'll need to delete (or move) ~/.e/e/config/e.cfg as it tells Evas to use software and if you change the theme it resets that file and after a restart it's back to software as well. This is just for playing but it's not too shabby at all

PKGBUILD:

Damn... Must get GL working for stupid Savage4!

(BTW, I've read some stuff about E17 being very, very unstable with GL... Is that true?)

Cam · 2005-06-21 11:14:43

Apparently it used to be but it seemed fine for me. I didn't notice any of the graphics glitches mentioned in the post I linked to but I may have been looking in the wrong spot. I've only got a Geforce MX5200 so it's not exactly cutting-edge and it felt nice and responsive, but unless you're using a background that needs to do a bit of rendering it's not really necessary. Cool though

having trouble with this, it compiles/install fine, but when I run it it segfaults...any ideas why?

have an nvidia geforce 4200go

Probably because OpenGL support is flakey at best and can only be used as a preview Offhand no, maybe you'd get a real answer from the edevelop.org forums. Best I can say is that it works for me :?

lol

ok, I'll post it to the e-forum

Unfortunaletly this happens...

The pkgbuild fails. I run it within e17 (using the ones from the community repo) and as root. And it fails.

it's because it pulls the code from CVS and obviously the latest CVS is broken. Wait a while and the issue should be fixed.

Lets reopen this thread shall we

I wonder, and I belive this is mosly pointed towards Cam, do you (or anyone) have the new .diff file? the one that changes so that e.cfg doesn't have to be erased all the time (http://get-e.org)

Cam · 2005-07-06 11:02:41

I dunno, I made the .diff file myself, I just had a quick glace at the site and couldn't find any updates to the previous code changes. If you find the where it says what to do then I'll make the diff, it's not really that hard though [man diff]

CyberTron · 2005-07-06 11:06:23

Hi!

Thanks for taking the time to look at it, here are the news, (it is really nothing special, but one doesn't have to remove e.cfg )

There's also some news regarding OpenGL mode. First of all if you haven't read about it yet, please read me previous newspost first. As as I said in the earlier post, one major problem with it was that the engine settings weren't being saved to e.cfg, so every time you restarted E, everything went back to software mode. This has been solved by Korda (he also posted the original instructions on enabling GL mode). This is just copypasted from the edevelop.org forums - this has been written by Korda:

"OK, I've figured out why the config changes weren't sticking.

There are a few lines missing in e_config.c which cause all the evas_engine_* variables to never be saved when e.cfg is written.

Inside e_config.c in the e_config_init(void) method, you'll need to add the lines:
Code:
   E_CONFIG_VAL(D, T, evas_engine_default, INT);                               
   E_CONFIG_VAL(D, T, evas_engine_container, INT);                             
   E_CONFIG_VAL(D, T, evas_engine_init, INT);                                   
   E_CONFIG_VAL(D, T, evas_engine_menus, INT);                                 
   E_CONFIG_VAL(D, T, evas_engine_borders, INT);                               
   E_CONFIG_VAL(D, T, evas_engine_errors, INT);                                 
   E_CONFIG_VAL(D, T, evas_engine_popups, INT);                                 
   E_CONFIG_VAL(D, T, evas_engine_drag, INT);

after all the other similar lines but before the line
Code:
e_config = e_config_domain_load("e", _e_config_edd);


This ensures that all the evas_engine_* config variables get written.
