Is xplr still supported on termux, or am I doing something wrong?

[sayanarijit]

Hey have you followed this instructions?

[dtomvan]

Yes I did, the only thing I changed was doing a git clone, so if the compilation fails again, I don't have to start over.

[sayanarijit]

Hmm I'm also getting some error with local build. Will investigate later.

[sayanarijit]

Now getting this error even with cargo install.

The error isn't very helpful. Probably need to raise this in mlua repo.

[dtomvan]

pkg install luajit then remove the vendored feature on mlua makes it compile and run.

[sayanarijit]

Nice 👍. So I guess it just needs dedicated packaging for termux, similar to how BSDs are doing it. We can probably add this in doc, but it seems there's little interest for this (no real usecase), so just closing this for now.
