Problems building Qt5 for WebAssembly



  • I'm trying to build Qt 5, pulled from the GitHub repository dev branch, for WebAssembly with thread support but having problems. I configured with this command:

    configure -no-warnings-are-errors -xplatform wasm-emscripten -platform win32-g++ -nomake examples -prefix C:/qt5/qtbase -device-model WASM_OBJECT_FILES=1 -feature-thread
    

    Note: I don't remember the correct option for specifying the setting for building Wasm object files, but I did get the correct wording when configuring which I know because I didn't get errors on it.

    I don't have the full output from running mingw-32-make since it's really long and most of the stuff from the beginning was cut off, but I'll show what I do have: https://gist.github.com/DragonOsman/075091a0b82ceba5596cf70dde2369ae .

    How do I fix the problem of it not being able to fin that stuff it says it can't find? Thanks in advance.

    You can use the prebuilt Qt for WebAssembly from the official Qt installer.

    Anyway, since your compilation fails on Qt3D, try skipping that module.
