 neobrain | ... of course as usual, after an hour of looking the answer presents itself right after asking: x86Pkgs.buildPackages.gcc seems to be what I'm looking for (instead of x86Pkgs.gcc) | 14:48:31 |

| neobrain | Any idea how I can build a sysroot with libc/libstdc++ headers? I know I need to use pkgs.buildEnv, but I'm struggling to find the right packages that contain the headers | 18:15:44 |
| neobrain | Looks like libgcc.out is the one | 18:37:28 |
| neobrain | * Looks like libgcc.out is the one, or rather pkgs.pkgsCross.gnu64.gcc-unwrapped for the cross-compiler | 18:45:41 |

 Grimmauld (any/all) | I wanted to build https://github.com/NixOS/nixpkgs/pull/414169 on android cross because upstream did some android changes and figured i might as well try.
However: both elfutils and stdenv is completely broken and does not build | 08:43:59 |
| Grimmauld (any/all) | (llvmPackages.compiler-rt is what is broken in the stdenv) | 08:45:17 |
 alexfmpe | FWIW pkgsCross.aarch64-android-prebuilt is in much better shape | 11:01:13 |
 Tristan Ross | Does https://github.com/NixOS/nixpkgs/pull/409265 fix the issue? | 15:52:28 |
| Tristan Ross | Or is it this? https://github.com/NixOS/nixpkgs/issues/380604 | 15:53:04 |

| xenia | is it possible to build a cross toolchain for rust and llvm for bare metal thumbv8m.main-none-eabihf (ie raspberry pi pico 2) within nixpkgs from source
i patched lib/systems/parse.nix to allow "thumbv8m.main" as a cpu and i'm trying
crossSystem = {
config = "thumbv8m.main-none-eabihf";
libc = "newlib";
useLLVM = true;
rust.rustcTarget = "thumbv8m.main-none-eabihf";
};
and then attempting to build buildPackages.rustc and i'm immediately running into errors building compiler-rt
i can post logs/a complete example but like my first question is whether this is a path worth following at all? has anyone ever done something like this? | 03:15:45 |
 K900 | Doubt it, you'll need some weird stdenv | 06:30:40 |
| K900 | And newlib probably isn't it | 06:30:44 |
