Unsolved Build Error : Qt WebAssembly for Linux (Uubuntu 18.04)

[Kallappa]

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

And one more problem is if one of the other basic Qt App gets compiled and build successfully and when i run it using *"emrun .html" using console i am getting application exit error as shown in image

So what is the reason for getting this.(I am using Firefox browser).
