Use older GLIBCXX ?

[bburdette]

Trying to get my project running again with beta15 in nixos. It compiles and links fine, but it seems like libstdc++ isn't new enough:

I think this is how you tell what versions are available?? Looks like the newest is 3.4.30, not 3.4.32.

I don't suppose there's any way to downgrade the required version?

This sounds more like a version mismatch in the nix repos to me 🤔
I'm not that familiar with nix but tauri itself doesn't require any specific glibc version.

[bburdette]

Solved the libstdc++.so.6 one by going to a newer nixpkgs version (current unstable). Got me a little further but still not working, probably because of this "DRI driver" thing:

[bburdette@HOSS:~/code/zknotes/tauri-zknotes/tauri/src-tauri]$ ./debugrun.sh
dbinit ret: Ok(())

... and rebuilt my system to match the nixpkgs in my project flake. That got rid of the DRI driver mismatch. Still have the GBM-DRV error.

Ok properly installed my nvidia drivers which got me to this:

[bburdette@HOSS:~/code/zknotes/tauri-zknotes/tauri/src-tauri]$ ./debugrun.sh
dbinit ret: Ok(())
Could not determine the accessibility bus address
AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer
AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer

And got that message to go away with WEBKIT_DISABLE_DMABUF_RENDERER=1. So down to just the 'accessibility bus address' thing. Stll not working but that might be because of code changes to my stuff. Now the "inspect object" menu brings up the debug environment, so seems normal-ish.

[bburdette]

Yep, back in business! Last thing was I had to change my old invoke declaration:

      // const { invoke } = window.__TAURI__.tauri;
      const invoke = window.__TAURI_INTERNALS__.invoke;

So to sum up:

• rebuild flake dev environment with newer nixpkgs (was using an old custom one)
• rebuild my system so DRI driver matches system DRI driver.
• properly install nvidia drivers
• run with WEBKIT_DISABLE_DMABUF_RENDERER=1
• update tauri 'invoke' declaration
