Hi there!
In reference to #40543

is cgo will support for wasm in future?

very unlikely as you would need a C to wasm compiler for you C dependencies.

I'm going to close this question as answered based on the answer from @randall77 above.

After a while of googling I found that C to wasm compiler already exists: https://emscripten.org/index.html

Is it possible to make CGO support webgl build target and allow to specify compiler e.g. with CC="..." and CXX="..." ?

This is not a proposal. Turning into a normal issue.

It may be possible, but somebody would have to do the work.

Thank you for your information! Looking forward to seeing this feature implemented in the future release of go!

Seems possible in theory, but very unlikely to happen. I think you should rather try to compile your Go code and C code to WebAssembly separately, load both in the same WebAssembly environment and then connect them somehow.

@neelance could you please provide some step-by-step tutorial about that?

Not really. The "somehow" meant that I don't know how exactly to do it, just that I think it should be possible.

Are there any updates/plans for that? I'm looking forward to see this feature as I really need it 😕
