[Wasm] Accessing QSettings crashes the application

    XMLWordPrintable

Details

    • WebAssembly

    Description

      Accessing QSettings from a webassembly application runs into:

      Uncaught RuntimeError: null function or function signature mismatch
    at QConfFileSettingsPrivate::initAccess() (new:245:10)
    at QWasmSettingsPrivate_onCheck(void*, int) (new:245:10)
    at eval (eval at completeLoadEmscriptenModule (qtloader.js:470:9), <anonymous>:11172:48)
    at req.onsuccess (eval at completeLoadEmscriptenModule (qtloader.js:470:9), <anonymous>:11149:11)

      Tried with emsdk 3.1.15 (3.0.0 to verify, as it seems to be used for the upstream Qt builds). Please find the attached example to reproduce the case.
