@dramforever:matrix.orgdramforever

chat is this a normal *System.rust

    rust = {
      platform = builtins.fromJSON (builtins.readFile "${./rust}/mips64el_mips3-unknown-linux-gnuabi64.json");
      rustcTargetSpec = "${./rust}/mips64el_mips3-unknown-linux-gnuabi64.json";
      # cargoShortTarget = "mips64el_mips3-unknown-linux-gnuabi64";
      rustcTarget = "mips64el_mips3-unknown-linux-gnuabi64";
    };

@emilazy:matrix.orgemily is the thing actually mips64el_mips3 03:55:31
@emilazy:matrix.orgemilyI hate that03:55:36
@dramforever:matrix.orgdramforeverthat's not a real cpu name04:00:44
@dramforever:matrix.orgdramforeverbut yes i need mips304:00:48
@dramforever:matrix.orgdramforeverrust's default mips64el is mips64r204:01:02
@dramforever:matrix.orgdramforever * but yes i need -march=mips3 04:01:18
@dramforever:matrix.orgdramforever why the hell does everything have mesonFlags 05:17:22
@dramforever:matrix.orgdramforever why the hell is there cmakeFlags and mesonFlags in pkgs/stdenv/generic/make-derivation.nix 05:18:03
@dramforever:matrix.orgdramforeveri can't fix this, i'll leave this be06:08:45

In reply to @dramforever:matrix.org
why the hell is there cmakeFlags and mesonFlags in pkgs/stdenv/generic/make-derivation.nix
I was very surprised too when I first encountered it.

@tomasajt:matrix.orgToma I'm guessing it is there so that splicing/cross doesn't make us use targetPackages or other hacky things (because cmake goes into nativeBuildInputs, shifting the offset)
just a guess, though
