Flycast does not launch on Raspberry Pi OS #207

Closed RGarciaLago closed 1 day ago

RGarciaLago commented 1 day ago

I installed Flycast utilizing Flatpak and the application does not appear when I attempt to launch it from the start menu. I'm on a Raspberry Pi 5 8GB model running the 64-bit of Bookworm on kernel version 6.6.

Please let me know if there's any other information you'd like, thank you.

Some logs would greatly help. Try flatpak run org.flycast.Flycast from a terminal

Thank you so much for your response. Here's the terminal log:

I tried running it again because the UTF-8 string errors seemed out of place and I got the following:

Yes, this is the root cause of the issue. The linux kernel shipped with the Raspberry Pi 5 uses a 16K page size by default. Unfortunately the Flycast flatpak binary is built for a 4K page, which is found on most linux systems. There is no easy way to have a dynamic page size so a special binary must be built for the Rpi 5. I'm not sure if flatpak allows this and how it can be done. The alternative is to build Flycast locally.

Thanks for looking into the issue! I'll go ahead and close the bug then.
