Found a solution. You can close this issue.

[JeremyRubin]

yay!

what was the fix?

[bnonni]

Yes, apologies, I should have explained. After many failed attempts with this error, I did the following:

brew install llvm
cargo clean
AR=/usr/local/opt/llvm/bin/llvm-ar CC=/usr/local/opt/llvm/bin/clang wasm-pack build

Not sure if its related, but I also installed secp256k1 via bitcoin-core here: [email protected]:bitcoin-core/secp256k1.git

Some combination of this seemed to resolve the error: failed to build archive: section too large referenced in rust-bitcoin/rust-secp256k1#283. I do not have an M1, but I think specifying AR and CC in the command instead of exporting to the env via zshrc or bashrc resolved this problem.

However, I'm now facing new errors, but those look to be with the rust code, so I'll open a new issue :)

[kevin-valerio]

export SKIP_WASM_BUILD=1 worked for me :)
