going on info here
and the sample kvark recently put up,
i’m trying to compile rust for asmjs or wasm, but i’m always getting errors like this … including from the one liner in the first link
rustup target add wasm32-unknown-emscripten info: component 'rust-std' for target 'wasm32-unknown-emscripten' is up to date rustc --target=wasm32-unknown-emscripten hello.rs error[E0463]: can't find crate for `std` | = note: the `wasm32-unknown-emscripten` target may not be installed
any ideas what i might have missed… i’ve got
rustup 1.7.0 (813f7b7a8 2017-10-30) rustc 1.24.0-nightly (f8af59d95 2017-12-13) cargo 0.25.0-nightly (930f9d949 2017-12-05)
I’ve got the emsdk installed and have managed to compile and run a ‘hello triangle’ type example from C++ -> asmjs, and seen that running in a browser; (but haven’t tried wasm with C++ yet).
I’d be ok with either asmjs or wasm … I’m told there’s more support for asmjs (emulation of SDL etc?) but it looked like the kvark sample was proving gl/IO interfacing for Rust<-wasm->browser through more rustic libraries (am I understanding this right… ‘emscripten’ is giving you emulation of native libraries that go though JS shims to get the appropriate functionality from the browser, and writing those shims is a work in progress)
EDIT - hacking around I at least managed to convert my rough ‘hello triangle’ sample from C++ to Rust via asmjs, I can see a rust-generated triangle in the browser now.
I’d still like to be able to get the wasm example working though
