 maralorn | joe (he/him): So I really hope it’s something you did. | 13:14:20 |
| maralorn | Which ghc version is it building? | 13:14:57 |
 joe (he/him) | err, whichever is built by 8.6.5-binary | 13:15:14 |
 sterni (he/him) | joe (he/him): which GHC? | 13:15:20 |
| joe (he/him) | I think however that I might have actually been using a very old nixpkgs | 13:15:24 |
| sterni (he/him) | and which platform | 13:15:26 |
| joe (he/him) | perhaps it was GCd on hydra | 13:15:35 |
| sterni (he/him) | maybe you have an overlay? | 13:15:53 |
| maralorn | There is no GC on hydra. | 13:15:55 |
| maralorn | 8.6.5 sounds like you are building 8.8.4? Should be cached. | 13:16:32 |
| joe (he/him) | specifically: /nix/store/q8qprh8ynbbmh0dgpz4ds82yz21ij8j8-ghc-8.10.4.drv | 13:16:53 |
| joe (he/him) | I'll investigate, I don't think I have any overlay which could be causing this. | 13:17:08 |
| sterni (he/him) | 884 and 8104 are cached | 13:17:20 |
| joe (he/him) | hmmm, this is the one required for my system by pandoc | 13:18:22 |
| maralorn | Sounds concerning. | 13:19:07 |
|  matthewcroughan joined the room. | 15:51:48 |
| matthewcroughan | Heyo. I wanna learn Haskell. Just wondering, can it run on microcontrollers like the ESP32? | 15:53:32 |
 pennae | not really | 15:58:04 |
 Roos | Oh, that would certainly be fun | 15:53:47 |
| pennae | ghc only targets x86 and arm/aarch64 atm | 15:58:38 |
| Roos | I think the writer of git-annex has something along those lines. | 15:54:07 |
| pennae | (other haskell compilers do exist, but afawk they mostly do bytecode or jvm, so they're out from the start for a µC) | 16:01:39 |
| Roos | Right: https://hackage.haskell.org/package/arduino-copilot | 15:55:54 |
| Roos | In reply to @roosemberth:orbstheorem.ch
Right: https://hackage.haskell.org/package/arduino-copilot Or C | 16:02:19 |
| maralorn | And I thought javascript runs on anything these days … | 16:08:20 |
| Roos | That's not necessarily a good thing xD | 16:08:50 |
 Las | cabal build on aarch64 for me gives me an ghc: could not execute: opt error, even though I have it in my PATH. Does anyone know how to fix this? | 16:10:45 |
| maralorn | Las: On nixos-unstable? | 16:13:25 |
| Las | Yeah | 16:13:31 |
| Las | It's from the 7th of May | 16:14:02 |
