GUI threading issue on Linux

[gamrXerus]

Xenia fails to compile on my system because pthread_yield is deprecated and sched_yield should be used instead according to the terminal.

When I comment out pthread_yield in src/xenia/base/threading_posix.cc xenia successfully compiles. However there is another issue when running the program. When using the GUI for xenia it crashes with this error

Specs:
Processor: Intel Core i7 10700KF
Graphics: AMD Radeon RX 6800
OS: Lubuntu 21.10 Mesa 22.0.0-devel

Is sched_yield consistently available throughout various distributions?

[gamrXerus]

I don't know unfortunately as I only use Lubuntu and I'm not a developer. Perhaps someone else here knows more about this stuff.

Oh, well, I see, it's a part of POSIX.1-2001 at least. Fixed in 701300e.

I'm not yet sure about the GUI issue, however — the current GUI code worked on my setup (Ubuntu 20.04, pure GNOME) in August or September, it's interesting. Though the first issue has been fixed, I'll reopen this thread due to the second.

I just downloaded and compiled the latest code and i can reliably reproduce the second issue by clicking File, Open and navigating my drive.
