Make it run again with current version of emscripten #1
Description
Hey there. Your project looks like a thing that I try to build right now. I want to attach the SDL output of a small WASM application to an Android touchscreen interface (an interface like https://github.com/Bodmer/TFT_eSPI, but I'm currently aiming at the M5Core2 implementation, the TFT part is close).
I tried to build your project today, with quite some luck. SDL2 is now working out of the box with emscripten, there are some nice examples here: https://erik-larsen.github.io/emscripten-sdl2-ogles2/.
The method filledCircleRGBA is no longer part of SDL2, so I replaced it with a simple draw_circle method. However I fail to build the project using your Makefile, I get em++: error: .bc: No such file or directory.
I was able to compile using em++.bat -Wall -I. -O3 -s USE_SDL=2 --js-library fauxels-view.js .\fauxels.cpp .\Arduino.cpp .\Serial.cpp -o dist/index.html, however I'm not able to adapt the Makefile accordingly; probably I will never understand Make in this life.
Now I have something running, with the template sketch.ino; and I don't see any graphics output. Should I be able to see something?
Cheers,
Roger
