Auto-compilation of Extensions doesn't work on nixOS #58

cyrneko commented 2026年03月07日 18:55:03 +01:00

Gram downloads a dynamically compiled binary as part of the extension compilation process, which doesn't fly on nixOS without the use of stub-ld.

This makes any extensions being compiled, well, not compile.

Relevant log snippet:

Caused by:
 failed to compile nix parser with clang: Could not start dynamically linked executable: /home/alexia/.local/share/gram/extensions/build/wasi-sdk/bin/clang
 NixOS cannot run dynamically linked executables intended for generic
 linux environments out of the box. For more information, see:

Interesting, I guess it's the WASI SDK being downloaded. It should be possible to provide it via Nix so that nothing is downloaded, hopefully.

Yeah it is the WASI SDK indeed, there's a note about this on #54

I have made it so that Gram doesn't need to download anything to compile extensions, as long as the WASI sysroot bundle is available in the location where Gram expects it to be.

On mac this is $HOME/Library/Application Support/Gram/extensions/build/wasi-sysroot.

You can see the implementation here:

In theory, this should make it possible to get things working on NixOS by installing the sysroot while installing Gram.

Going to close this, the Wasm compilation is never going to be perfect across all platforms and my inclination right now is to replace it and the current language support model with something more like how helix works.
