running rust programs fails, could not resolve host

[Mandarinoooo]

trying to run any of the examples using the rust language fails with the following error message:

warning: spurious network error (3 tries remaining): [6] Could not resolve hostname (Could not resolve host: index.crates.io)

Happy to supply y'all with all info needed, I'd really like to get this thing working because it looks great. Cheers!

I see.

For now you can use the Flatseal program to grant Workbench the network permission then restart Workbench.

works, but I ran into a new interesting issue!

error: linker `clang` not found
  |
  = note: No such file or directory (os error 2)

might be OS-related, I'm running Bluefin. Currently trying if installing clang from homebrew fixes it.

[Mandarinoooo]

Doesn't, of course. Do you maybe know where clang might be missing (as in, where do I need to install it)?

[Mandarinoooo]

dunno if someone did something but it magically works now hooray

[sonnyp]

Needs a fix

[Mandarinoooo]

my bad, somehow forgot I didn't even get an update.
Probably doesn't surprise you, given that this is a flatpak, but the issue still persists on OpenSUSE Aeon.
