Can't `wasm-pack build`: No available targets are compatible with triple "wasm32-unknown-unknown"
Closed this issue · 10 comments

I was trying to run README instructions and this is what I got. It seems to have something to do with clang (and I'm running Apple clang version 12.0.0 (clang-1200.0.32.2)).
OS: MacOS 11.2.3
error: failed to run custom build command for `secp256k1-sys v0.4.0`

Did you mean 'build'?
If you believe you received this message in error, try re-running with 'wasm-pack -- buildclang'

Got the same issue on cloud ubuntu by default, but then upgrading to clang-12 from clang-6 helped there.
JeremyRubin commented
You should probably open this issue in rust-secp rather than here?
I should figure out the min version of clang required for wasm32-unknown-unknown.
Short of that, run llc --version and does it say it supports wasm?
naumenkogs commented
Sorry it seems I don't have llvm installed and I can't install it atm. I will come back here in a bit, if I don't respond soon feel free to close.
JeremyRubin commented
fixed?

please gimme couple more days :)
