 Alex | It's likely mentioned in the "writing packages for cross" section of the manual. | 00:33:30 |
 outfoxxed | doesn't look like a new regression, at least not to this package, which is the root of the linking issue | 00:35:24 |
|  @senk0:element.senk0.com left the room. | 00:35:40 |
| Alex | Have you looked at why it's in the build time closure?
Changes to other packages may have resulted in it being required where it wasn't before.
I suspect that one of the dependants in the chain can be overridden to not require it. | 00:38:02 |
| outfoxxed | probably, but it looks far easier to just fix it | 00:38:32 |
| Alex | It's a Python package, so see the "overriding Python packages" section of the Nixpkgs manual. | 00:39:26 |
| outfoxxed | doesn't seem to | 02:48:02 |
| outfoxxed | libstemmer = builtins.trace "${targetPackages.libstemmer} ${buildPackages.libstemmer} ${pkgs.libstemmer}" targetPackages.libstemmer;
| 02:48:35 |
| outfoxxed | prints 3x and only in one of them is targetPackages set correctly

that's certainly unhelpful

| outfoxxed | pkgsHostHost appears to work, but I'm not sure if thats the best one
I'm reading it as pkgs[runs(is linked) on host][doesn't codegen so irrelevant?] | 03:35:11 |
| outfoxxed | so pkgsHostTarget is identical but maybe more correct? | 03:35:24 |
 dramforever | that should be the build = x86_64, host = riscv64 libstemmer | 03:39:59 |
| dramforever | if it doesn't work something else went wrong | 03:40:08 |
| dramforever | wait no | 03:41:36 |
| dramforever | are you even sure you need to cross this to riscv64? | 03:41:46 |
| outfoxxed | I'm getting linker errors that look like this

| 03:41:54 |
| dramforever | this is probably a build dependency of something | 03:41:56 |
| dramforever | iiuc this should be for host = x86_64 | 03:42:10 |
| dramforever | it's a dependency of sphinx | 03:42:15 |
| dramforever | the docs generator | 03:42:18 |
| dramforever | it's possible someone just broke it on x86_64 recently or something...? | 03:42:33 |
| outfoxxed | Redacted or Malformed Event | 03:43:09 |
| outfoxxed | looks like not just sphinx but mostly sphinx | 03:43:23 |
