 srasu | would a git link be useful? It's not a very large project, just a personal template I use for building C projects | 16:20:14 |
 K900 | If it's your own project, you probably want to just use Meson | 16:21:23 |
| K900 | And Meson will do the right thing | 16:21:28 |
| srasu | I've been told to use meson before and not had a good time | 16:22:18 |

You'll want to get everything from the cross set and it's __splicedPackages so dependency attributes work correctly pkgsCross.mingwW64.__splicedPackages
It's also best to avoid packages when you're doing cross compilation as it can obscure which packages are being talked about, instead use nativeBuildInputs directly https://github.com/NixOS/nixpkgs/blob/85813b7cfeb12a87da5506035f73b5b18a0a50c3/pkgs/build-support/mkshell/default.nix#L41 | 16:23:26 |
| srasu | packages only has stuff that's not actually used by the build process, just build tooling | 16:24:20 |
| srasu | * packages only has stuff that's not actually used by the build process, just dev tooling | 16:24:26 |
| srasu | I can give that a go though | 16:25:03 |
| Artturin | You should put tooling that does not care about target to depsBuildBuild, that way you won't have to rebuild them as for rarer platforms their depsBuildHost versions aren't usually cached | 16:25:39 |

| srasu | oh thanks! | 16:27:26 |
| Artturin | You want to use llvm tools so do (mkShell.override { stdenv = pkgs.llvmPackages_18.stdenv; }) | 16:29:30 |
| Artturin | And remove the llvmPackages from the dependency attributes | 16:29:53 |

| srasu | I've started to get this weird mktemp failed to create directory via template with /tmp/nix-shell.JtWooZ/nix-shell.XXXXXX | 16:36:27 |
| srasu | no such file or directory | 16:36:40 |
| srasu | google is being no help | 16:36:43 |
| srasu | Redacted or Malformed Event | 16:43:38 |
| srasu | Redacted or Malformed Event | 16:43:41 |
| srasu | Ok, that went away with a reboot, which is weird, but ok | 16:45:17 |
| srasu | Trying to set things up like you posted, but I seem to be running into weird errors presumably because I had originally wanted the devshell to work for both cross compilation and usual compilation. I think I'll separate them out into different devshells though and hopefully that'll work itself out. | 16:48:24 |
| Artturin | You can add the build compiler to depsBuildBuild | 16:49:35 |
| Artturin | it'll be non prefixed | 16:49:57 |
| Artturin | $CC_FOR_BUILD | 16:50:08 |
| Artturin | * And in $CC_FOR_BUILD | 16:50:16 |
| Artturin | It'll look for libraries in nativeBuildInputs | 16:50:36 |

The buildPackages would give you the dep for placement in nativeBuildInputs
