Need memfd

[Krutonium]

• A brief description

memfd is required to run some software such as OpenRCT2. It is not implemented so the game can not run.

• Expected results

Build x64 OpenRCT2 following the guides here. https://github.com/OpenRCT2/OpenRCT2

Sound can be worked around with PulseAudio. You can also work around the eventual fatal libGL error by recompiling mesa with either swrast or llvmpipe.

But it looks like OpenRTC2 requires multilib (32 bit) so you'll hit that brick wall eventually I think. There's a user voice here.

No, this is for x86_64 builds (which are default as of right now).

[therealkenc]

In VcXsrv uncheck "Native opengl" in the the Extra Settings panel of XLaunch. You'll get best performance with llvmpipe from here. But strangely, I am not getting your failed to load driver: swrast even without replacing libGL.so. This is on Xenial for what it's worth, but not clear that should matter. If you see the swrast error, it means you need a software renderer. (Because WSL doesn't know you have a video card.)

[therealkenc]

This got lost in the noise and was left open. The OP cites a bunch of ALSA #1631 and absence of a OpenGL pipeline. Ref #486 for PulseAudio. sudo apt install mesa-utils will get you llvmpipe on WSL.

[therealkenc]

/dupe #3542 and #237. For practical purposes, audio has new LZ #5816. GUI apps is #938. The most recent chatter on OpenGL using a third-party X server is #6154.
