I have been trying to use wasm32-unknown-unknown on termux (an app that emulates linux on android). It has worked before by using this tutorial: Non-rustup setups - Hello wasm-pack!
But after updating my packages it doesn't work anymore. (Even when reinstalling wasm32-unknown-unknown with the correct version). The error I get says, that wasm32-unknown-unknown has been compiled by the wrong compiler. I suppose this is because the (new) rustc termux provides is compiled from a source tarball. Is there a way to compile wasm32-unknown-unknown myself?
