hello, i'm new to nix and i was looking for a way to configure a clean cross platform environment for i686-elf as mean to try and follow osdev wiki

is there a way or nix-shell ready to just provide cross-compilers shell?

In reply to @k900:0upti.me
For i686 you should be able to just use the default gcc with -m32

John Ericsondo you know what to do about this? https://matrix.to/#/!VjfUzaKsXokUdnQcvP:nixos.org/$0MvZSnxZ46Tco6vWU7qKEqRe3RdJUpyN94QvUCgCTso?via=nixos.org&via=matrix.org&via=nixos.dev

TLDR: how to cross-compile qt6 with qtwayland and maybe qtwebengine?

Hi, does anyone know anything about this problem?

It can't build.. buildPackages.qt6.qtquick3d??
Okay, it kinda can't find TARGET Qt::Quick, but why? According to https://hydra.nixos.org/build/270608875/nixlog/1, this error is not expected...

afaik build of this derivation is caused by the
nativeBuildInputs = [ pkg-config ] ++ lib.optionals (!stdenv.buildPlatform.canExecute stdenv.hostPlatform) [ buildPackages.qt6.qtwayland.dev ];
in pkgs/development/libraries/qt-6/modules/qtwayland.nix

I'm not sure that if is correct fix for qtwaylandscanner not found problem, and I'm also not sure if it will fix it, but I need to try this, probably.

UPD 2 days after writing the first part of this message
After git pull master I got a new error with qttranslations:
