* wasm: remove duplicate “--bind” optionMorten Johan Sørvig2021-11-191-2/+0
| | | | | | | | | Not a compile option, and also added to the linker options above. Change-Id: Iab2107d4b5ee4bc73e85b3cd5070f1a96b3a5a3b Reviewed-by: David Skoland <david.skoland@qt.io> Reviewed-by: Lorn Potter <lorn.potter@gmail.com>
* wasm: increase default initial memoryLorn Potter2021-11-041-2/+6
| | | | | | | | | | | | | | | | Some apps may need more initial memory when linking, emscripten will fail with: wasm-ld: error: initial memory too small This increases the default initial memory form 16MB to 20MB. Larger apps might still get this error, in which case QT_WASM_INITIAL_MEMORY can be set.

* wasm: enable event dispatcher asyncify supportMorten Johan Sørvig2021-11-041-1/+1
| | | | | | | | | | | | | | | | | | | | | Misc. fixes, including: Fix a couple of typos in the JavaScript code. Also, macros- within-macros don’t work, (without resorting to preprocessor token pasting), so remove the debug output for now. Limit the exec() “simulateInfiniteLoop” workaround to top-level application exec() only. This way, asyncify can be used for nested QEventLoop::exec() calls. (Emscripten supports one level of suspend only, so we don’t want to use that for the top-level exec(), but instead use it for dialogs and such). Use the new QEventLoop::ProcessEventsFlag::ApplicationExec enum value to detect the exec() call type.

* wasm: don’t set exit_runtimeMorten Sørvig2021-06-231-1/+1
| | | | | | | | | | | | | | | | | | Go with Emscripten’s default of not shutting down on main() exit; this allows for writing main() in such a way that avoids the exec() workaround. Existing main() implementations (which do use the exec() workaround) do not shut down Qt cleanly anyway, so we gain little by shutting down the Emscripten runtime. Applications can set this flag if they do want to shut down on main() exit: LFAGS += -s EXIT_RUNTIME=1 Change-Id: I52e1cc2bc907d1d2146822713e39b7610db3f95b Reviewed-by: Tor Arne Vestbø <tor.arne.vestbo@qt.io> Reviewed-by: Lorn Potter <lorn.potter@gmail.com>
* wasm: enable MODULARIZE option and set EXPORT_NAMEMorten Sørvig2021-06-221-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | Make Emscripten generate a global constructor function ("createQtAppInstance()") instead of a global javascript module object. This enables more fine-grained control over module instantiation; previously the module object would be created when the runtime javascript was evaluated, and the number of emscripten module/instances was limited to one per page. Set EXPORT_NAME to “createQtAppInstance” which avoids collisions with other non-Qt Emscripten modules on the same page. A further improvement would be to include the app name in EXPORT_NAME, but this is not done at this time. Update the code in qtloader.js to call the constructor function instead of working on a global module object. The qtloader.js API is functional before the wasm and Emscripten modules have been instantiated; store properties and forward to the Emscripten module when it's created.
