Subject: Re: About ico-homescreen in mesa-10.0.5

Quanxian,

I didn't find a JIRA feature or bug, so I created 
TIVI-3136<https://bugs.tizen.org/jira/browse/TIVI-3136> and 
PTF-193<https://bugs.tizen.org/jira/browse/PTF-193>.

Out of curiosity, why go with 10.0.5 instead of 10.1.2?  The Mesa 
website<http://www.mesa3d.org/> suggests going with the 10.1.x series since 
10.0.5 and 10.1.1 were released concurrently, and since 10.0.5 is the last 
release in the 10.0.x series.

[Wang, Quanxian] Good point. I have done some investigation on 10.0.x. Original 
plan I upgrade mesa to 10.0.x. But I think you comment will be fine. I will 
have a try on 10.1.2 and then make a decision which is right for us.

Thanks,
-Ossama

Quanxian,

On a related note, do you have a corresponding JIRA feature/bug for the Mesa 
upgrade?  I'd like to reference it in the Wayland/Weston 1.5 update feature 
request (TIVI-3136<https://bugs.tizen.org/jira/browse/TIVI-3136>) since the 
Wayland/Weston development team no longer test again Mesa 9.2.1.

Thanks,
-Ossama

Hi, Masayuki Sasaki & Nobuhiko Tanibata

I am planning upgrade mesa from 9.2.1 to 10.0.5. However when I install 
ico-uxf-homescreen. It will fail to go to UI.
By the way, with default weston desktop shell, it will be fine.

After the investigation, I have found some hints. But the information is not 
enough. I turn to you who are familiar with code of ico-homescreen.

Breakpoint 5, weston_load_module (name=0xbffff86c "ivi-shell.so", 
entrypoint=0x8066701 "module_init") at compositor.c:3933
3933                       module = dlopen(path, RTLD_NOW);

It will warning:(the last characters are messed)
warning: Could not load shared library symbols for °(<
                                                     p.

However it will continue and will stop at the another module 
/usr/lib/weston/ivi-controller.so
ico_plugin_loader.c:110
110             module = dlopen(path, RTLD_NOW | RTLD_GLOBAL);
(gdb) p dlopen("/usr/lib/weston/ivi-controller.so", 0x102)
*** Error in `/usr/bin/weston': corrupted double-linked list: 0x08088040 ***
….Hang here….

From that, I could not get enough information. Basically I think some unknown 
symbol not exists. But I could not get that.

Do you have any suggestion or comment for that?

If anyone could lend me a hand or give me some hints, it will be greatly 
appreciated.

Thanks

Regards

Quanxian Wang
