 aleksana 🏳️⚧️ (force me to bed after 18:00 UTC) | Plus I don't understand haskell yet | 11:35:45 |
 sterni (he/him) | Yeah, I did not mean you should do it. | 11:36:01 |
 Alyssa Ross | the most pragmatic approach might be to focus on other loongarch64 things for now and hope upstream has bootstrap binaries before too long. | 11:36:32 |
| aleksana 🏳️⚧️ (force me to bed after 18:00 UTC) | I'm bootstrapping from ghc package in debian ports, hopefully this could work | 11:37:21 |
| sterni (he/him) | As I was saying, Adam Joseph did try this in the past and concluded that it's too big a pain to get to work | 11:38:27 |
| sterni (he/him) | but it may be possible, not sure. | 11:38:32 |
| aleksana 🏳️⚧️ (force me to bed after 18:00 UTC) | I can also let loongson guys to compile an ideal binary tarball if it really doesn't work | 11:39:58 |
 emily | we don't put anything not built by Hydra on tarballs.nixos.org | 12:01:20 |
| emily | I guess just fetchurling something wouldn't be the end of the world though, we already have some mystery-meat third-party binaries in tree… | 12:01:38 |
| emily | but we'd really prefer to avoid it if at all possible of course | 12:01:53 |
| emily | binaries from Hydra >> binaries from upstream >>> all other binaries | 12:02:16 |
| aleksana 🏳️⚧️ (force me to bed after 18:00 UTC) | => nix-build -A pkgsCross.loongarch64-linux.haskell.packages.ghc984.ghc
evaluation warning: build: x86_64-linux host: x86_64-linux target: loongarch64-linux
this derivation will be built:
/nix/store/dpwqr9489b1mkgmili5fpxci31if3n2a-loongarch64-unknown-linux-gnu-ghc-9.8.4.drv
Well | 12:49:15 |
| emily | huh. host should be loongarch64-linux unless you use buildPackages? | 12:50:47 |
| emily | splicing issue maybe? | 12:51:02 |
| aleksana 🏳️⚧️ (force me to bed after 18:00 UTC) | In reply to @emilazy:matrix.org
splicing issue maybe? Very likely | 12:51:29 |
| aleksana 🏳️⚧️ (force me to bed after 18:00 UTC) | Because the attribute is referenced from buildPackages: https://github.com/NixOS/nixpkgs/blob/master/pkgs/top-level/haskell-packages.nix#L482 | 13:04:18 |
| sterni (he/him) | haskell.packages.*.ghc is like stdenv.cc | 13:04:56 |
| sterni (he/him) | haskell.compiler.* would be cross compiled | 13:05:10 |
| emily | hm, wouldn't it make more sense to use buildPackages explicitly for that? | 13:08:49 |
| emily | I assume that pkgsCross.foo.* is going to have host foo unless * starts with buildPackages. (with stdenv as an unfortunate exception) | 13:09:20 |
| emily | I guess there are probably other unfortunate exceptions already though. | 13:09:31 |
| emily | WTB universe without the GNU idea of cross… | 13:10:01 |
| sterni (he/him) | as said, it’s like stdenv with all the weirdness involved, this is probably the best way to do it. You can’t even do an equivalent of libc/cc split | 13:26:18 |
