is it possible to build emscripten (like emcc / em++) itself to WASM?
I'm trying to make an "Online IDE" that can compile c/c++ into wasm and run it in the browser.

I've noticed that emcc is written in python. is it possible to run emcc using something like https://github.com/dgym/cpython-emscripten ?

Everything is possible with enough effort and investment :) But I don't think this is something Emscripten team would do itself.

Meanwhile, you might want to check out https://github.com/binji/wasm-clang and the demo at https://binji.github.io/wasm-clang which has at least Clang ported to Wasm and compiling other inputs to Wasm from within Wasm.

Yes, I've tried that, and I implemented its stdin support.(binji/wasm-clang#6) But it can't support interactive input.
Opening this issue is only a discussion of the possibilities. I'm not expecting Emscripten team would do it.

I think this is a duplicate of #6432

(In general, I think this would be interesting, and if someone has the time to do it I'm be interested to see the results! But as @RReverser said, this isn't something anyone is currently working on AFAIK)
