 Rick (Mindavi) | Yeah, last I checked it worked fine :) | 22:13:29 |

 trofi | What is the correct way to pull in openmp related to stdenv? Example package failure: https://github.com/NixOS/nixpkgs/pull/150912 | 18:14:48 |
| trofi | I think it would be useful for clangStdenv to contain reference to matching llvmPackages. | 18:19:24 |
| trofi | Heh https://github.com/NixOS/nixpkgs/issues/79818 | 18:28:28 |

 Las | Do I need to have nativeBuildInputs = [ buildPackages.stdenv.cc ]; to support cross-compilation? | 17:27:08 |
| Las | This is in alsa-firmware | 17:27:12 |
| Rick (Mindavi) | That's probably related to the attached patch, I don't think it's always needed | 17:52:36 |

Do I need to have nativeBuildInputs = [ buildPackages.stdenv.cc ]; to support cross-compilation? having that is redundant | 18:03:44 |
| Artturin | you can confirm it by building ".#pkgsCross.aarch64-multiplatform.alsa-firmware" and then removing buildPackages.stdenv.cc and building again | 18:04:29 |
| Artturin | nothing will be rebuilt | 18:04:35 |
| Las | Is the gcc used for cross compilation still called gcc? | 19:01:56 |
| Las | * Is the gcc used for cross compilation still called cc? | 19:02:05 |
| Rick (Mindavi) | No, I don't think so, you can check in a nix-shell with echo $CC | 19:11:19 |

Do I need to have nativeBuildInputs = [ buildPackages.stdenv.cc ]; to support cross-compilation? that compiler is for building something for the build system and is only necessary if you e. g. need to compile the build system which is executed during the build then | 23:17:46 |
| sterni | putting it into nativeBuildInputs is hacky at best though, you can get such a compiler by simply putting something into depsBuildBuild (probably another way to force it?) and it'll be available as $CC_FOR_BUILD. | 23:18:27 |
| Las | Thanks. | 23:18:51 |
| Las | TBF I think that's hackier, if you have to put "something" in but it doesn't matter what it is. | 23:19:14 |
| 20 Dec 2021 |
|  kunrooted changed their profile picture. | 09:14:29 |
| sterni | Las: well just put buildPackages.stdenv.cc in there | 09:25:12 |
| sterni | then it's in its correct place plus you get it as $CC_FOR_BUILD | 09:25:25 |

I've always wondered how this worked. I wonder if I'd be able to refactor some of my derivations at work to stop explicitly taking things from pkgsBuildHost and instead putting things intodepsBuildBuild. | 14:20:33 |
