Emscripten - compile your C/C++ to JavaScript
Emscripten is a source-to-source compiler that takes C/C++ code and compiles it to browser-runnable JavaScript code. It works by first compiling the C/C++ code to LLVM IR code using clang/clang++, then using a LLVM backend called Fastcomp to generate the JavaScript output. The compiled code can then be run directly in the browser. Emscripten allows running large web applications, developing for multiple platforms, and porting performance critical libraries to the web. It enables debugging of compiled code directly in the browser developer tools.
Emscripten - compile your C/C++ to JavaScript
- 1. EmscriptenCompile your C/C++code to javascript Actually, it's from LLVM bitcode to javascript KK – Ying Reui Liang 2015/10/XX
- 2.
- 3. It's a sourceto source compiler bases on LLVM Compile your C/C++ code into browser runnable javascript code Averagely, it's faster than handwrite code “Asm.js”

- 5. C/C++ source | clang/clang++ | V LLVM IRcode | Fastcomp (LLVM backend) | v Javascript code
- 6. em++ helloworld.cpp -c-o helloworld.bc
- 7. em++ helloworld.bc -ohelloworld.html
- 8. Running in terminal Runningin browser

- 10. Large web applications Multiplatform Performance critical library

- 13. The native way Likewe always do The browser way Compile your codebase with -gX (X is 1~4) Then debug them on the browser
- 14. With -g4 youcould even set breakpoints on C++ source code inside browser devtool!

- 21. Currently, there's mainlythree ways to port a library to javascript using Emscripten
- 22. - The firstone - If you're using portable C/C++, or the dependencies you use had already been ported Just compile it Like jsoncpp, which relies on C++ std libraries
- 23. Write corresponding javascriptcode for functions in that library Like library_sdl.js - The second one -
- 24. If the libraryyou want to port has friendly architecture for porting Use html5.h and other headers which Emscripten provide Treat Emscripten like another platform Like part of SDL2 does - The third one -
- 25. If you wantto add certain port to official repo of Emscripten... Check these out Or you can discuss with me, I just port SDL2_ttf last month :)
