 n8henrie | Oh, maybe I can just build on a nix shell on arch and get the matching wxgtk... | 22:16:28 |
 @ghpzin:envs.net | Iirc there is a way to not fill output git hashes importing Cargo.lock with allowBuiltinFetchGit = true; | 22:19:29 |
| @ghpzin:envs.net | Iirc a way to not fill output git hashes while importing Cargo.lock is setting allowBuiltinFetchGit = true; | 22:19:55 |
| n8henrie | Building in a nix shell with the matching version of wxGTK worked! Thanks a ton! I'll experiment with the built-in fetchgit as well, thank you for the suggestion. | 22:24:34 |
| n8henrie | Just to close the loop, allowBuiltinFetchGit works a treat and is probably an even better approach. Thank you! | 22:33:31 |
| n8henrie | This way I can make sure the package builds or exit 125 for the bisect. If the package builds, run the nixosTest and get a result. Fingers crossed. | 22:34:37 |

 crop | i am trying to use this crate in a project that i work on on a nixos machine: https://github.com/HadrienG2/hwlocality
it depends on a c library that i add to the shell.nix in the buildInputs = with pkgs; [hwloc] and then set the libpath with libPath = with pkgs; lib.makeLibraryPath buildInputs; ... the library is loaded dynamically as the error appears only when i try to use the crate in rust.
the error is target/release/multi_thread: error while loading shared libraries: libhwloc.so.15: cannot open shared object file: No such file or directory
any suggestions how to fix this? | 22:59:37 |
| crop | i now added the following line to the shell.nix
LD_LIBRARY_PATH = "${pkgs.lib.makeLibraryPath buildInputs}";
but i thought this is not recommended. | 23:25:43 |
| crop | its not "recommended" because now i am missing other libraries (pipewire-...-jack-lib) ... and i don't know how it got put into the LDLIBRARYPATH variable automatically | 23:33:14 |
| crop | ok i found the solution for the jack problem but it actually doesn't help for hwloc to be found .... which is strange because one time i run the build (but i don't know what i changed it worked) | 23:46:20 |
| crop | ok it seems to work if i use the "vendored" hwloc build by cargo ... not ideal (and only without the LDLIBRARYPATH thing which seems to be what i shouldn't do anyway) | 23:50:39 |
