pkgsCross.mingwW64.pkgsStatic.stdenv.targetPlatform.config is "x86_64-w64-windows-gnu" for some reason, unlike pkgsCross.mingwW64.stdenv.targetPlatform.config which is "x86_64-w64-mingw32" as expected.

The Windows case doesn't seem to be covered here, since for MinGW-w64, config doesn't use the result from lib.systems.parse.tripleFromSystem pkgsCross.mingwW64.stdenv.hostPlatform.parsed, which is "x86_64-w64-windows-gnu". Instead, we have

https://github.com/NixOS/nixpkgs/blob/cefcf19e1c6d4255b2aede5535d04064f6917e9b/lib/systems/examples.nix#L311-L316

So I guess stdenv.hostPlatform.{config,libc} should be passed to crossSystem conditionally.

Bump, this issue is quite unfortunate when attempting to build static apps through nix.

I was able to build a static windows (mingwW64) executable with 34cefd7dea46e02932c2413ae7068574d0352ce9. I think this closes the issue? Thanks @wolfgangwalther! :heart:

edit: It seems #303849 is not merged yet. So I'm just leaving this information here.

Hi, is there any possible work around for this? (just facing this now after upgrading from 22.11 to 24.05)

The work-around is to "properly" instantiate cross compilation.

Compare the following on nixos-24.05 at dc2e0028d274394f73653c7c90cc63edbb696be1.

❯ nix-build '<nixpkgs>' -A pkgsCross.mingwW64.pkgsStatic.stdenv
[..]

vs

❯ nix-build --expr '(import <nixpkgs> { crossSystem = { config = "x86_64-w64-mingw32"; isStatic = true; }; }).stdenv'
/nix/store/m77b2dla2w3k8cx4ggjdmm2j8nldy6j6-stdenv-linux

The problem is not that static mingw64 cross-compilation is broken. The problem is that pkgsCross and pkgsStatic cannot be arbitrarily combined.

[wolfgangwalther]

The work-around is to "properly" instantiate cross compilation.

Whether that's "proper" or not... is a question of it's own. For example for linux, pkgsStatic will use musl. If you just do isStatic = true that way, it will not be musl, right? But a lot of nixpkgs is assuming Linux + Static = musl.

So imho, there is too much knowledge / dependency in nixpkgs about pkgsStatic already to say it's not correct to use it.

Also.. is it really the composition that is broken? What about the following?

nix-build --expr '(import <nixpkgs> { crossSystem = { config = "x86_64-w64-mingw32"; }; }).pkgsStatic.stdenv'

Yup, broken as well.
