@QNeko there's something not clear here

are you sure you are launching correct gcc? 😁
Dero
i have no other gcc because it is a fresh install
Dero
[Debian/12]::(~/stuff/HelloWorld) which gcc
/home/fdero/.nix-profile/bin/gcc
Ziky
check if you have installed package like stdlib-dev
Dero
i need to install it for nix? or do i need to uninstall it if present?
Simple Sorcerer

Doesn't it bother you that the g++ needs an additional file .o?)

I seem to remember that additional built-in object files are also needed for compilation. But I'm not sure

Here it is. It should exist in the system by default. For some reason you don't have it.
IMHO you dont need it if you are not going to compile anything

On fedora (fresh-install) i don't even have as and ld btw

i'm running many virtual machines, it pretty much never works even if i'm tryng many configurations

it's normal to not have ld and as installed with gcc?

while I'm not certain it's the source of your problems, avoid nix-env
Dero
what do you mean avoid nix-env?
Simple Sorcerer

https://askubuntu.com/questions/1037611/development-tools
Try reinstalling the default development packages
They are called something like "base-devel"
Roxifλsz 🇱🇹
what do you mean avoid nix-env?
quite literally, it links shit a bit weirdly and as a result can have file overshadowing issues and what not, a nix shell or putting it in your nix profile would probably work better
Dero
nix-shell refers to the so called: multi-user installation?
Roxifλsz 🇱🇹
probably, a proper full nix install would be best indeed
Simple Sorcerer

Sorry, just now I remembered that you want to use nix
Simple Sorcerer
But it seems to me that the package you need to install should be called something like "base development package"
Roxifλsz 🇱🇹
nix-shell refers to the so called: multi-user installation?
either way just try out nix-shell -p gcc cmake ... without those installed in nix-env, that should drop you in a shell with the programs available and actually working. I'm not sure if the single user installation might be screwing you over or perhaps even something like selinux on fedora just denying access to nix store files but it showing up as "no such file or directory" errors
Dero
the reason i opted for single-user installations is that these VMs i'm running have no systemd
Dero
but anyway, i tried installing the multi-user, i have some weird problems starting the nix-daemon. I might consider installing a fresh distro native with systemd and see it that works

well assuming all the permissions are ok on your single-user installation then nix-shell should still work there, at least I haven't seen anything to the contrary. if you keep running into nix issues, I'd recommend asking in this chat: https://t.me/nix_org

when tryng the thing in nix-shell -p cmake gnumake gcc llvm it works fine

lovely, so the issue was indeed with nix-env then, assuming you changed nothing else about that system
Dero
am i running some sort of container behind the scenes when using nix-shell -p?
Roxifλsz 🇱🇹
no, it just does some environment variable black magic
Dero
Okay, i will setup a proper native env and try again tomorrow maybe
Dero
thanks for the help you gave me so far

Hello everyone.
How to install nvidia 470xx driver in fedora 41
klimi
Dero
For who's intrested in the whole nix thing. I installed it with a multiuser installation after setting up systemd, i also disabled SELinux, i then installed the whole set of tools once again but i ended-up with the same problems. Just to be clear i'll repeat once-again that i had the idea of using nix to package my free-open-source-software both for linux and macos, but since i had so many problems and since on two different linux distro i had different behaviours regarding as, ld, crti.o and stuff like that i decided to postpone or even abort this idea. The question remains on how could i package stuff in the most easy and low-effort and low-commitment way. For now i already set up an msi graphical installation for windows and snap installation for linux distro who supports it. For now that's enaugh i will get back on the problem in the future
Dero
Since most of the packages i need are only for the build itself, since the runtime is basically indipendent from all of this outside of libc and other stuff basically everybody knows how to install probably it can still be packaged for nix using the nix-shell -p functionalities but i'm not sure.

i already did something like that with snap
Dero
btw i think i got it. Probably nix packages like gcc and stuff are not even supposed to be used outside of a default.nix
if inside of my default.nix i use them to build. The end result works fine
Dero
at least, this is on Fedora/40 with systemd multiuser install + disabled SElinux

Don't ask meta questions. In other words, don't ask to ask. Questions like "Does anyone know XYZ?", "Has anyone used XYZ?" or "Can someone help me?" are all considered meta questions because they don't specify what your actual problem is.
These questions give the impression that you want people to approach you and offer their help as if they don't have any other work to do. Now doesn't that expectation make you look like an idiot?
If you have a question ask it directly. You are more likely to get a response that way.
