Description
Hello,
I built Qt (current dev from june 1: c12065ac7811176ae3437431300ccb71d2d2419f ) like this:
configure -release -nomake tests -nomake examples -cmake-generator Ninja -feature-thread -sse2 -feature-opengles3 -prefix /home/jcelerier/libs/qt6-wasm-install -qt-host-path /home/jcelerier/libs/qt6-host-install -platform wasm-emscripten
which seems to work and gives me: qtbase/src/corelib/global/qconfig.h
#define QT_FEATURE_thread 1 #define QT_FEATURE_future 1 #define QT_FEATURE_concurrent 1
My app is itself built with:
-DCMAKE_C_FLAGS='-sASYNCIFY -pthread -O3 -msimd128 -msse -msse2 -g0' -DCMAKE_CXX_FLAGS='-sASYNCIFY -pthread -O3 -msimd128 -msse -msse2 -g0'
and has, additionnally which I kinda cargo-culted from various places, including Qt's source code:
add_link_options("SHELL:-s ASSERTIONS=0") add_link_options("SHELL:-s SAFE_HEAP=0") add_link_options("SHELL:-s USE_SDL=2") add_link_options("SHELL:-s STACK_OVERFLOW_CHECK=1") add_link_options("SHELL:-s FETCH=1") add_link_options("SHELL:-s WASM=1") add_link_options("SHELL:-s FULL_ES2=1") add_link_options("SHELL:-s FULL_ES3=1") add_link_options("SHELL:-s MAX_WEBGL_VERSION=2") add_link_options("SHELL:-s USE_WEBGL2=1") add_link_options("SHELL:-s ERROR_ON_UNDEFINED_SYMBOLS=1") add_link_options("SHELL:-s TOTAL_MEMORY=2000MB") add_link_options("SHELL:-s USE_PTHREADS=1") add_link_options("SHELL:-s FETCH=1") add_link_options("SHELL:-s WASM_BIGINT=1") add_link_options("SHELL:-s MODULARIZE=1") add_link_options("SHELL:-s WEBGL2_BACKWARDS_COMPATIBILITY_EMULATION=1") add_link_options("SHELL:-pthread") add_link_options("SHELL:-s ASYNCIFY" "-s" "ASYNCIFY_IMPORTS=[qt_asyncify_suspend_js, qt_asyncify_resume_js]") add_link_options("--bind") set(CMAKE_EXECUTABLE_SUFFIX ".html")
I build it with emscripten's qt-cmake wrapper.
And yet, doing a right-click to show a QMenu kills both chrome and firefox (latest stable) with messages about having to rebuild my app with ASYNCIFY continuously spammed in the console 
What else am I missing ?
