      Hi,

      I am trying to install Qt WASM for linux system. As i followed the following link for Qt WASM setup https://wiki.qt.io/Qt_for_WebAssembly and installed emscripten using https://emscripten.org/docs/getting_started/downloads.html.

      also installed platform specific pre-requisites using https://emscripten.org/docs/getting_started/downloads.html#platform-notes-installation-instructions-sdk
      under Linux section.

      So the flow is as follows

      sudo apt-get install python2.7
      sudo apt-get install cmake
      sudo apt-get install default-jre
      
      git clone https://github.com/emscripten-core/emsdk.git
      cd emsdk
      git pull
      
      ./emsdk install sdk-fastcomp-1.38.27-64bit
      ./emsdk activate --embedded sdk-fastcomp-1.38.27-64bit
      source ./emsdk_env.sh
      

      And then Installed Qt5.14.0 (evaluation version) using

      ./qt-unified-linux-x64-3.2.3-online.run
      

      Finally after setup.
      if i build, Qt appication for WASM i am getting the following error for "make".

      shared:ERROR: '/home/kmb/Qtwasm/emsdk/fastcomp-clang/e1.38.27_64bit/binaryen/bin/asm2wasm ./Test.temp.asm.js --total-memory=67108864 --trap-mode=js -O3 --mem-init=./Test.js.mem --mem-base=1024 --wasm-only -o ./Test.wasm --mvp-features' failed (-9)
      Makefile:219: recipe for target 'Test.js' failed
      make: *** [Test.js] Error 1
      

      Kindly let me if any thing missed or any solutions.
      Thanks in Advance
