Web build fails on macOS ("LLVM error: section too large")

[abey79]

Currently, a newer version of llvm/clang must be installed on mac, because the Apple-provided one fails building wasm with:

failed to build archive at /Users/tsaucer/src/rerun/target_wasm/wasm32-unknown-unknown/release/deps/libpsm-43030b67c35315ca.rlib: LLVM error: section too large

We should figure out a way to either fix the build, or make it so that using pixi solves the issue.

This fixed it for me:

> rm -rf target_wasm
> brew install llvm
> echo 'export PATH="/usr/local/opt/llvm/bin:$PATH"' >> ~/.zshrc
> clang --version
Homebrew clang version 20.1.4

The PR that first caused this problem was:

• Introduce a DataFusion-backed table widget #9764

To get it to work I had to specify homebrews llvm installation directly. I.e. PATH="/opt/homebrew/opt/llvm/bin/:$PATH"

[Wumpf]

should check whether

• Add libgfortran5 dependency to fix MacOS OpenCV & numpy issues #10214

had any effect
