    Hello,

    I am unable to build my project(Based on Qt Widgets UI and C++ ) using Emscripten and Qt for WebAssembly. I am facing below mentioned errors-

    error: unknown type name 'HINSTANCE'
    fatal error: 'Windows.h' file not found
    

    As I have read the information from the forum, the windows.h is not part of the emscripten sdk.
    Please suggest how should I include Windows API into the WebAssembly project?

    Thanks,
    Pradson

      I would assume you cannot, e.g. read https://github.com/emscripten-core/emsdk/issues/153

      Emscripten is a cross-compiler, it compiles code to the web - it can't compile windows-specific code, as those APIs are not implemented on the web platform.
