Installing GDC on the VM #8395

Open etcimon opened 6 months ago

etcimon commented 6 months ago

I'd like to add a template to develop using systems programming languages such as C or D, but the VM currently doesn't support it.

Here is where it fails when running apt install gdc for example:

Hey! Thanks for reporting this. I think we're hitting here a limitation. We run all code inside rootless podman/docker containers, and because of this it cannot always run commands like mount and mknod. I'm checking if there's some kind of workaround, because mounting should still be possible in userspace, even without root access.

Checking why mknod is used and how we can work around that.

Hmm, we cannot reproduce it yet, here's a devbox where we installed gdc: https://codesandbox.io/p/devbox/optimistic-boyd-ngqg73?file=/.devcontainer/Dockerfile

I used SSH on the VM and ran an apt install to obtain this error
