Set up WebAssembly development environment
To set up the development environment for WebAssembly:
- Go to Preferences > SDKs > WebAssembly.
- In Emscripten SDK path, enter the root directory where you installed
emsdk. - Qt Creator configures the Emscripten SDK environment for you if your Qt for WebAssembly version supports the
emsdk.
- Go to Preferences > Kits to check the WebAssembly kit that Qt Creator creates. If C/C++ does not show the Emscripten Compiler to use, check that emscripten is set up correctly.
