meta-ti + meta-qt5

[-- Attachment #1: Type: text/plain, Size: 512 bytes --]

hi there,

not sure if this is the right place to ask... but since i am about to ask
about QT5, OE and TI platforms, i am starting here!

so, i read a couple of blog posts about getting Qt5 on beaglebone, however
it's not clear to me what's the latest status is. has anybody been able to
use/enable OpenGLes either with KMS, or directfb or eglfs platform driver?
The only thing i have seen are references to using the 'minimal' platform
driver.

if so, can i get some pointers?

thanks!

Are you asking about the status in general (ie, outside of the yocto infrastructure) ? In general, eglfs,kms has been proven working for more than a year now.

Within meta-ti, eglfs should work if the display driver is available (fb or drm). The only reason I stopped at "minimal" on Beaglebone was because the "display" driver part was not integrated at that time on Beaglebone (in meta-ti) and hence OpenGL ES driver couldn't be installed.

Have you seen those multiple iterations of libgles-omap3 patches from Prabu 
we've been discussing here lately? Those are one of the necessary steps in 
getting Qt5 on our platforms (although w/o OMAP4/OMAP5 support)...

I have few fixes on top of the latest patchset that I have been playing with 
in the past few days - I was planning on pushing all that soon.

Do you have any plans extending it in meta-ti?

well, thanks for the quick answer. yes, i meant within OE, using meta-qt5.
it's good to know that it's working outside of it, though.

do you have instructions (conf files + scripts) to run Qt5 + eglfs (and
kms) as platform driver?

thanks

Denys,

Yes, Getting Qt5 (specifically, qtbase) with eglfs (and next kms) with meta-qt5 + meta-ti is the goal.

yes, that's the blog posts, i had read. but that doesn't deal with eglfs.

i was trying to build qt5 with eglfs support using something like this:

+GL_DEPENDS = "virtual/libgles2 virtual/egl"
+QT_GLFLAGS = "-opengl es2 -eglfs"

since i don't have x11 support in my distro (on purpose), qt5base fails to
configure properly since the EGL auto detect fails to build for that reason:

| EGL auto-detection... ()

The instructions build eglfs as well (without xcb), as in the below patch. Just that I cannot test it on platform due to the absence of GLES2 driver.  verbose flag in the qt configuration (qt5.inc) would help debug what is going wrong.

yeah, i am using something similar *but* i do not have x11 in
DISTRO_FEATURES, and i suspect you might have it, right? without X11
feature, the x11 -dev packages are pulled/installed, and then the qtbase
configure script will fail to 'check' for EGL.

Heh, I was having similar issues with Prabu's recent libgles-omap3 patches. 
It would try to pull x11 packages due to -dev dependencies and complain that 
DISTRO_FEATURES lacks X11 setting... It's not exactly the same issue, but 
seems related.

Re: meta-ti + meta-qt5

[Sundareson, Prabindh]

I have validated libgles-omap3 on the AMSDK 5.07 build configuration (that does not have X11 enabled), so what you faced may be a different issue on the libgles front.

I would wait for the verbose log from Nicolas for the qt5 issue he faced,

Prabu

I use Qt5 on pandaboard, with the Qt5 kms driver. There are some
things needed to be done in Qt5 KMS to make it link with the OMAP4 PVR
headers. And since you don't support the hardware pointer that code
has to be avoided.

Correct, becasue your patches were missing the actual x11 recipe, which I had 
to add - see my other email earlier. :)  But I agree - it's a slightly 
different issue.

so, my issue was related to mesa in fact !

you can read that thread if you are interested:
http://lists.openembedded.org/pipermail/openembedded-core/2013-June/080205.html

basically, i was building for qemuarm, so with mesa, and it's mesa that
doesn't work fine if X11 is not in DISTRO.

thanks anyways for all the support/discussion.
