 ius | Which makes sense, because patchelf doesn't target ppc.. so I think I can't use any of *Platform to tell the 'native' and 'cross' scenarios apart | 15:45:52 |
 symphorien | ah so it's hostPlatform not targetPlatform maybe | 15:46:46 |
| ius | No, that's x86_64-linux as well ('the platform the executables run on). I think targetPlatform` ought to be right, but it might not have a meaning outside of gcc/libc itself? | 15:54:14 |

| symphorien | ah I see your point | 16:00:17 |
| symphorien | indeed you can't make the distinction between "it will be used for powerpc" and "it will be used natively" | 16:00:53 |
| symphorien | I suppose the if should happen in pkgs/stdenv/cross/default.nix | 16:02:47 |
| symphorien | ...which seems to slowly converge to the solution you already have, so I'll stop there giving you bad advice | 16:10:00 |
| ius | Your attempt is much appreciated though 🙂 | 16:23:35 |
| ius | Ah, another angle: removing patchelf from systemd's nativeBuildInputs works (because then only the patchelf from stdenv will be in PATH). | 20:12:08 |
| ius | Which makes me wonder, why is patchelf listed there in the first place? Doesn't stdenv provide patchelf by default? Many other packages seem to assume so | 20:13:06 |

 siraben | What's the most direct way to cross-compile the ISO? | 05:26:46 |
| siraben | thanks John Ericson for merging my cross PRs | 06:14:45 |

Many other packages seem to assume so yes that seems unneeded... https://nixos.org/manual/nixpkgs/stable/#sec-tools-of-stdenv guarantees that patchelf is present at least. | 11:08:34 |

| ius | symphorien Sandro : Thanks | 13:06:49 |
| ius | Sandro: I think you can also drop coreutils based on symphorien's doc link. And not sure about getent (it's included in glibc, but e.g. musl doesn't provide it - however systemd doesn't build on musl anyway; not sure about other libcs though) | 13:11:20 |

 sterni (he/him) | John Ericson: if you have the time, could you review https://github.com/NixOS/nixpkgs/pull/131076? it has a change to cc-wrapper (only affecting Ada though), so I just wanna confirm that what I'm doing is in the spirit of said wrapper | 12:45:39 |
| sterni (he/him) | also edend up doing something similar to pkg-config's setupHook, so you may be able to give useful feedback | 12:45:58 |
 John Ericson | Ok | 12:46:01 |
| sterni (he/him) | John Ericson: thanks a lot! | 14:21:14 |

John Ericson: thanks a lot! np! sorry i didn't see before, always feel free to ping me | 15:16:30 |
| sterni (he/him) | John Ericson: btw I also got gnat to build as cross compiler, although it is probably only useful for bare metal targets because gcc's build system somehow falls apart when building libada for a cross compiler: https://github.com/NixOS/nixpkgs/pull/131136 | 16:44:17 |
| John Ericson | I saw! | 16:52:14 |
| John Ericson | That's good because the libs should be built separately anyways | 16:52:19 |
| John Ericson | If you make that separate derivative like I did for libgcc but then we actually use it, I'll be very happy! | 16:52:52 |
| sterni (he/him) | I'll look into building it separately but it seems there is very little accurate documentation on it atm | 16:53:25 |
| John Ericson | Even better if always use the separate derivation including in native case | 16:53:36 |
| John Ericson | Ok losing internet | 16:54:11 |
