[Buildroot] SDL2+directfb combo does not work as built by buildroot-2018.02.3

[Peter Thompson]

I cannot get directfb + SDL2 working on Beaglebone Black  (see Bugzilla
#4232 and SDL forums)
    https://bugzilla.libsdl.org/show_bug.cgi?id=4232
    https://discourse.libsdl.org/u/PeterThompson/activity

I do not want to use X windows for the video driver.  I tried adding OpenGL
ES to the rootfs but for that I need efl which in turn needs the kernel
built by Buildroot.  I have a working kernel which I want to work on
separately to attach a new display and prefer not to be forced to always
build it through Buildroot.

Suggestions?

Note: SDL2+directfb combo used to work on igepv2 buildroot-2015.08.1.   I
am just trying to migrate to the beaglebone black.

RESOLVED
SDL2-2.0.8 works on Beaglebone Black using DirectFB provided the following
patch is applied to SDL2-2.0.8.

https://hg.libsdl.org/SDL/raw-rev/751cdc74d55c

The patch was created by Sam Lantinga and will be incorporated into the
next release of SDL2.

Great, care to send a proper patch with your signed-off-by for this?

Hi Peter

My original plan was to wait for the next SDL2 release thereby allowing
SDL2 to fix itself before updating the SDL2_VERSION in  buildroot.

Otherwise we have to change buildroot SDL2_VERSION to  point to the
temporary patched SDL2 source for download:
http://www.libsdl.org/tmp/SDL-2.0.zip
OR
somehow change buildroot to download this patch and apply it to the
downloaded SDL2-2.0.8 before compiling (I am not sure how to do this in
buildroot).

Then we would need to re-change this all back when the new release of SDL2
incorporates this patch.

..... unless I am missing something.....

.. Or simply include the hg commit as a .patch file in the package.

Correct.

Do you know when sdl2-2.0.9 is planned? 2.0.8 is what we are using both
for 2018.02 (the current long term support version), 2018.05 (the
current release) and master (what will very soon become 2018.08).

I checked with Sam - this is his note back...

"I'm not sure, but I think we're going to start on it soon. We have a bunch
of good improvements in 2.0.9 for folks."

Now that I see how easy it is ... add file containing Sam's patch called

0001-hg-libsdl-org-SDL-raw-rev-751cdc74d55c.patch
to the SDL2 package

... I can easily submit a proper patch with signed-of-by to buildroot

Let me know what you would like.....
