nixGL VS not-os

How can a program accomplish this? by using/doing something like virtualization? emulation? syscall/API translation? e.g. like WINE?

Essentially, running stuff that needs GL graphics is a bit funky... There's a workaround called nixGL though.

I think installing Calibre is a good use case for installing Nix (www.nixos.org).

Unfortunately, you might also need https://github.com/guibou/nixGL to run graphical apps under Nix. It's a shell script to use the correct OpenGL library.

Try the NixGL wrapper.

Are you running the Nix package manager on not-NixOS? If so I recall needing NixGL for OpenGL integration.

$ nix-channel --list home-manager https://github.com/nix-community/home-manager/archive/release-22.05.tar.gz nixgl https://github.com/guibou/nixGL/archive/main.tar.gz nixos https://nixos.org/channels/nixos-unstable

Needs a separate program to run GUI applications on non-NixOS systems

IMO the proper solution to this is Nix/Guix, since they have the best of both worlds (sharing libraries where possible, but allowing different versions where needed). Shame that libGL is a mess and as such is difficult to get right in this way, and as such you need hacks like https://github.com/guibou/nixGL for most GUI stuff. That said, people are working on improving the situation.

I get what you mean, but keep in mind that for every distro you're reliant on the community to get nvidia support integrated. Also if you only have few apps that require it, then the nixGL flake is not bad. https://github.com/guibou/nixGL

nix-channel --add https://github.com/guibou/nixGL/archive/main.tar.gz nixgl && nix-channel --update warning: unable to download 'https://cache.nixos.org/v5djb4jw3hg4brdbidqaspin8n8isyq6.narinfo': SSL peer certificate or SSH remote key was not OK (60); retrying in 259 ms these derivations will be built: /nix/store/gm6gq44ivdqgmrsvlsr08d2nqjircgds-nixgl.drv building '/nix/store/gm6gq44ivdqgmrsvlsr08d2nqjircgds-nixgl.drv'... while setting up the build environment: executing '/bin/bash': No such file or directory builder for '/nix/store/gm6gq44ivdqgmrsvlsr08d2nqjircgds-nixgl.drv' failed with exit code 1 error: build of '/nix/store/gm6gq44ivdqgmrsvlsr08d2nqjircgds-nixgl.drv' failed error: program '/usr/bin/nix-build' failed with exit code 100

Hi. I'm new to nix and want to ask if you have an idea how to build an ISO image file of not-os and run it on QEMU virt vanager?

Maybe not-os?

oh oops, I think I was intending to type "crowd source" but I really met "crowd fund".

I do want to finish my FreeBSD cross PR, but is is hard. We already have NetBSD working, including building the kernel, so I think it is better to start there.

I opened https://github.com/cleverca22/not-os/issues/16 because I think that would be the absolute easiest first step, with the fewest moving parts. But I don't know how kernels, even Linux, are packaged into bootable thingies at all.

I also found this: https://github.com/cleverca22/not-os

It's like an OS that has builtin salt/ansible/chef/puppet.

Because Nix language describe the OS instead of what to change/configure it's superior to these tools, and solves the problem that supposedly same machines are drifting apart.

For example if in the CM you tell it to install a package, then change your mind and remove the entry that does it. The package will remain installed.

With NixOS if you remove the package from configuration, it's gone.

I personally really like Nix's building capability. For example I can use it to generate a minimal docker container. It requires some knowledge, but I can also modify compilation options in dependencies (like remove unneeded functionality).

It looks like there's also an option to similarly build lightweight OS images[1]. I haven't tried it yet but looks cool.

You might want to check out https://github.com/telent/nixwrt and https://github.com/cleverca22/not-os as solutions with similar goals. The former is a promising but yet-unfinished way of using Nix to manage a router, while the latter is a similar way of using Nix to generate an immutable OS image.
