My local build of tinygo can't build wasm either.

I followed the following page for the local build.
https://tinygo.org/getting-started/linux/

Specifically, I used the following command to build

export CC=clang
export CXX=clang++
make llvm-build
make
make gen-device

Where do you maintain the dockerfile for tinygo/tinygo-dev?
If you don't have a repository at the moment, you may want to create a tinygo-dev branch in tinygo-org/docker.

This is the Dockerfile https://github.com/tinygo-org/tinygo/blob/dev/Dockerfile

[deadprogram]

This might have been fixed by #1309 you just need to wait for the dev Docker build and try it out.

@sago35 can you recheck this now? Thank you.

[sago35]

I still get the error.

@deadprogram
Should we just add make wasi-libc ?

[deadprogram]

Yes, that seems needed.

[sago35]

merged.

[sago35]

I have already confirmed that it is working correctly.
