Lakka 5x : Build fail on GPICase.arm/Pi02GPi.arm (2023-09-14_5.x) about lakka-libreelec

[ShigeakiAsai]

Also, build fail on Lakka 5x Pi02GPi.arm (2023-09-14_5.x) was same reason.
I change the issue title (add Pi02GPi.arm).

Now I am trying fix about this issue.(exclude yabasanshiro core on GPI Case.arm/Pi02GPi.arm)

[ShigeakiAsai]

Currently I'm checking my modification, but the other problem is happened.

Build fail was happened at chailove core on Pi/GPI Case/Pi02GPi project without my modification.
This build fail reason is chailove component can't get from gitlab.com.
(chailove refers to https://gitlab.com/grumbel/SDL_tty.git,)

It may be gitlab trouble, so I'm waiting a moment resolve this.

Note:
chailove build fail was fixed by "chailove : update #1883" (639a307).
And I confirmed that it was fixed.

I will report about this issue.

Thanks.

Dear Lakka team

I would like to suggest about this issue that the yabasanshiro core is excluded on building GPICase and Pi02GPi devices.

The reason is bellow.

In GPICase and Pi02GPi device, both use OPENGLES="bcm2835-driver"in device options file.

• Lakka-LibreELEC/projects/RPi/devices/GPICase/options
• Lakka-LibreELEC/projects/RPi/devices/Pi02GPi/options

bcm2835-driver copies related header files to toolchain during building.
But GLES 3.0 header files are not included in these header files.
Because bcm2835 supports only GLES 2.0 I think.

On the other hand, the yabasanshiro core refers GLES 3.0 header files.

Therefore, GPICase and Pi02GPi building are failed.

By the way, RPi.arm device excludes the yabasanshiro core.

Just like RPi.arm device, it's better to exclude yabasanshiro core on both devices I think.

P.S.
I prepare pull request now.

Sorry for my strange English.
ASAI, Shigeaki

I think Pull Request #1884 was something noisy.
I hope Lakka team fix this issue please.

Thanks,

According to Libretro Docs - Sega - Saturn (Yabause) https://docs.libretro.com/library/yabasanshiro/ .

Background
YabaSanshiro is a fork of Yabause. It requires OpenGL 3.3 or OpenGL ES 3.0.

Pi4 supports OpenGL ES 3.1, but Pi 1,2,3,Zero,Zero2 support OpenGL ES 2.0 only.
Therefore, YabaSanshiro works on Pi4 or later and does not work Pi3 and before.
About this, I asked developper devmiyax.

I think it will better that YabaSanshiro core is excluded in device=RPi/RPi2/RPi3/GPICase/Pi02GPi.

Thanks,

This issue was fixed. (Commit:57f5502e8257fe8582a988392653f1c4e5e685ea)

I confirmed it on my build environment. (with temporarily RetroArch build is exclude)

I will close this issue after I confirm nightly build result.

Thanks,
ASAI, Shigeaki

Close.

Because, This issue is for build fail of yabasanshiro core on GPICase.arm/Pi02GPi.arm.
It is fixed already by commit "Dont build yabasanshiro for unsupported gles2 boards".(57f5502)

Therefore, I close this issue

Note:
A build fail is still occurred on GPICase.arm/Pi02GPi.arm.
But, it is due to another cause (Retroarch).

Thanks,
ASAI, Shigeaki
