Reproduction

https://github.com/Eveeifyeve/Tauri-Repo-Objc-exception

Solved! Flake template at https://github.com/eveeifyeve/nix-tauri

Requires Nix!

To build dev enviroment nix develop --impure or just install direnv and it will do it for you.

To run bun issue to run the issue and you will see.

Expected behavior

It should not include this error and work.

### Additional context

But as a nix user on macos this should really be happening to really need this flag to work.

Any updates/progress to this???

No update and no progress. To be honest, i don't think anybody will look into this anytime soon. Our best bet here is if someone from the nix community could take a look.

Maybe the solution is something in the same spirit as #8588 here.

This is happening to me as well. I think it's a problem with [email protected]. The dependency chain is: tauri v2.0.0-beta.14 -> cocoa v0.25.0 -> cocoa-foundation v0.1.2 -> objc v0.2.7 -> objc_exception v0.1.2. Related issue: link.

I'm a complete dummy when it comes to compilers, but I followed the above-mentioned GitHub issue and deduced it has something to do with gcc. I removed $PATH entries that contained gcc and the project worked just fine, since the build system defaulted to /usr/bin/gcc.

However, gcc is just clang in disguise on macOS. I figured that adding llvmPackages.libcxxClang to devenv.shells.default.packages could also work. Lo and behold, this is what did the trick!

TLDR: change your flake.nix

              ++ (with pkgs; [
                llvmPackages.libcxxStdenv
+               llvmPackages.libcxxClang
                darwin.libobjc
                rustup
              ]);

I am looking to make an unofficial flake template over here
