Qt web assembly: configure kit

Question

I want to test out QT WebAssembly for my scientific program. Therefore, I installed emscripten.

$em++ --version

returns

Answer 1

1. You need to copy the .emscripten file from emsdk directory to your home (/home/myUsername).

2. You need to fix the paths in the file manually (See example below).

Notice that .emscripten file , at least in the version (1.39.8) i am using, is a python script (maybe a bug?)

example file before edit:

import os
emsdk_path = os.path.dirname(os.environ.get('EM_CONFIG')).replace('\\', '/')
NODE_JS = emsdk_path + '/node/12.18.1_64bit/bin/node'
LLVM_ROOT = emsdk_path + '/upstream/bin'
BINARYEN_ROOT = emsdk_path + '/upstream'
EMSCRIPTEN_ROOT = emsdk_path + '/upstream/emscripten'
TEMP_DIR = emsdk_path + '/tmp'
COMPILER_ENGINE = NODE_JS
JS_ENGINES = [NODE_JS]

after edit:

import os
emsdk_path = os.path.dirname(os.environ.get('EM_CONFIG')).replace('\\', '/')
NODE_JS = '/home/myUsername/node/12.18.1_64bit/bin/node'
LLVM_ROOT = '/home/myUsername/upstream/bin'
BINARYEN_ROOT = '/home/myUsername/upstream'
EMSCRIPTEN_ROOT = '/home/myUsername/upstream/emscripten'
TEMP_DIR = '/home/myUsername/tmp'
COMPILER_ENGINE = NODE_JS
JS_ENGINES = [NODE_JS]

When above steps are completed qt creator was able to detect the Emscripten Compiler with no errors.
