Build issue for WebGLCanvas.js.

[kuldeepmore]

I have emscripten installed at my end.
I have performed following steps to build the code.
$ source emsdk_env.sh
$ ./emsdk activate latest
$ cd openh264-js-master
$ make

But I am getting following error.

cd openh264 && git checkout 41caf381520005c612a2089e070b35c045cc3e77 && emmake make OS=linux ARCH=asmjs

Makefile:23: recipe for target 'WebGLCanvas.js' failed

From the error log I think that it is not able to get
wget "https://raw.githubusercontent.com/mbebenita/Broadway/master/Player/WebGLCanvas.js"

Could you please provide the instruction to solve this issue.

Thanks,
