[Vinchethescript]

Right now I just realized that the problem was that the nodejs package wasn't installed in Termux. Since I can't check right now, I'll keep this issue open if VSCode still doesn't work.

[Vinchethescript]

So, I installed the nodejs package in Termux. Now, on VSCode, I get these errors:

I can't open any file or start terminal, but it connects to Termux.
This is what I get on the output:

[Vinchethescript]

I have recently switched to Pop!_OS, and it still doesn't work...

[bamurtaugh]

Based on the warning you're seeing: The remote host may not meet VS Code Server's prerequites for glibc and libstdc++, the extension is essentially warning you that it needs certain versions of glibc and libstdc++, and it looks like you don't have those versions available.

This link explains more and has some tips on getting those installed for different distros.

[Vinchethescript]

I tried checking that page as you told me, but there isn't anything about Termux. Isn't there an alternative way (e.g. compiling the libraries)?

[bamurtaugh]

Digging into this a bit further, it actually looks like Termux support is an outstanding feature request: #1338. The user in that thread faced similar issues with the server being unable to start and Node.

[Vinchethescript]

Oh, in that case, I would also suggest to add Termux support, because it looks like there isn't Termux/AArch64 support on Remote. A good thing would be adding a separated option dedicated for Termux, so that the Linux one will not be edited for Termux's support.

[bamurtaugh]

Thanks for the feedback here @Vincysuper07. Since I believe the request here is covered by 1338, I'll go ahead and close this thread (please feel free to comment/upvote in that thread too), but please let me know if you have any other questions or feedback, and I'd be happy to chat further!

@bamurtaugh, another thing: Googling about how to compile the requirements on Termux, I found out that Termux does not support glibc. I didn't look for libstdc++, but I know that glibc is not supported.
