Black screen when using on aarch64 (asahi linux/m1)

[BetterUnborn]

Hi,

I compiled it from sources using latest commit 4c0b882 on my up-to-date asahi linux on aarch64 apple M1. It compiles without any modifications using the build-linux64.sh script, and I copied the *.gro files from a windows TSE installation from steam into it.

When I launch the game the menu screen shows up. But when I start a game, it is stuck with a black screen. Gnome tells me that the program does not react anymore (--> stuck in a loop?). The console shows this:

./ssam                                                                                  ─╯

Any help appreciated :)

What compiler did you use?

[BetterUnborn]

The one that came preinstalled with Asahi:

gcc --version                                                                           ─╯
gcc (GCC) 12.1.0

Just to test out ... tried also with clang, the result is the same. Verified in build output that indeed the compiler I thought is chosen.

clang --version                                                                         ─╯
clang version 15.0.7
Target: aarch64-unknown-linux-gnu
Thread model: posix
InstalledDir: /usr/bin

Remark: I can also see the Croteam and Godgames logos including seemingly correct animations. Just whenever the engine should draw its in-game graphics screen is black and the game hangs. Also when I don't interrupt at the logos and the games does circle through the initial demos.

Can you try the workaround in #40 ?

[BetterUnborn]

Can confirm with that workaround the level starts, and I could play for a few minutes without a problem 👍

Oh, so some speicifc bug on Aarch64. I'll have to check if some the hack for armhf maybe need to be enable on Aarch64 as well.

[BetterUnborn]

Okay, thanks for the help!! I have tried several levels and have seen no issues so far ... just the resolution was capped at something 1400ish, dunno why ... but that's another topic.

Shall I close this issue or leave it open as reference for a possible aarch64 fix?

[ptitSeb]

Leave it open yeah, I'll try to work on that later.
