 Alyssa Ross | In favour of having an e.g. cmakeBuildHook that does all the automatic stuff, and which can be built separately. | 17:59:16 |
 sielicki | symphorien: I don't think we even need to write the toolchain to the nix store as a derivation. I'm kind of spitballing here, but I guess this could just be a pure nix string handled by the existing lib.systems.parse code | 18:00:35 |
| sielicki | thanks all for the input, I'll play around a bit more with this | 18:03:16 |
 Sergei Zimmerman (xokdvium) | Speaking of the current cmake situation, the system where cmakeFlags and mesonFlags are constructed in make-derivation has quite big overhead. makeCMakeFlags and makeMesonFlags are one of the hotter functions in the whole of nixpkgs | 18:03:17 |
| Sergei Zimmerman (xokdvium) | It would be nice if the hooks were bound to the stdenv and were memorised accordingly | 18:03:51 |

 zimward | can someone explain to me why i get a gcc that targets x86_64-linux in a derivation from a stdenv that has riscv32-none-elf as its target? | 18:06:22 |

can someone explain to me why i get a gcc that targets x86_64-linux in a derivation from a stdenv that has riscv32-none-elf as its target? $CC is that? | 18:55:02 |
| Artturin | Reproducer? | 18:55:07 |
| zimward | like nix develop nixpkgs#legacyPackages.x86_64-linux.pkgsCross.riscv32-embedded.newlib-nano

there is also the correct gcc in there with the target triplet prefix (and is set as the CC, but when i add cflags it tries to use the incorrect gcc) | 19:01:33 |
