[Buildroot] [PATCH v3 1/1] python-kivy: new package

[Enoch W.]

Status update request
=====================

Hi,

This package has not reached the buildroot master branch as yet. Is it
available on some other github? Is the mailing list patch the final word?
I'd like to help. I have experience with this excellent library on other
platforms... [and porting to buildroot should not be more difficult than
porting to Android :-)]
I hope it can work with directFB or sdl2 only as I have issues with
openGL ES2 support on my platform (Beaglebone Black with the
4.14.67-ti-rt-r74 kernel).

Thanks, Enoch.

The patch is available on the mailing list, and on patchwork [1]. The
most recent version of the patch as of now is v5, and it's awaiting
review.

Awesome, it would be helpful if you could apply and test the patch,
and report back with your findings. If everything works as expected,
you can reply with your 'Tested-by:' according to section 21.3 of
Buildroot's manual [2]. This could help it get merged quicker.

I can't comment on this particular use case, because I haven't tried
it. I do know that Kivy relies heavily on GL/ES, and you're probably
not going to get far without a working implementation.

Maybe one of Mesa's software renderers would suffice?

[Buildroot] [PATCH v3 1/1] python-kivy: new package

[Joseph Kogut]

Signed-off-by: Joseph Kogut <joseph.kogut@gmail.com>

Changes v2 -> v3:
- Bump version to 1.10.1
- Remove upstreamed patch to remove getconf dependency
- Split config comments for OpenGL and glibc deps
- check-packages fixes


Changes v1 -> v2:
- Remove unnecessary build dependencies (suggested by Yegor)
- Require toolchain w/ glibc, as Kivy builds with others, but
  seems to segfault with (at least) musl.
