    XMLWordPrintable

Details

    Description

      Emscripten comes with Emscripten toolchain cmake file.

      -DCMAKE_TOOLCHAIN_FILE=$HOME/emsdk/emscripten/1.38.27/cmake/Modules/Platform/Emscripten.cmake -DCMAKE_BUILD_TYPE=Debug -G "Unix Makefiles"

      but upon testing, other things also need to be set:

      • compiler arguments (--bind)
      •  linker arguments (-L plugins/platforms/ -l qwasm, -s USE_WEBGL2=1 )
      • dbug arguments (-s ASSERTIONS=2)
      • WASM_OBJECT_FILES
      • copy qtloader.js files
      • sed wasm_shell.html
      • setting Qt5_DIR type of paths
      • ? something else
