install_emscripten.sh Not Working On Linux

[ghost]

I'm using Xubuntu 14.04 64 bit.

When I run the install_emscripten.sh script it produces this:

Installing the Emscripten SDK to /usr/local/emsdk. Press any key to continue...

Unsupported OS, cannot update!
Error: No tool or SDK found by name 'sdk-1.13.0-64bit'.

Looking into the python script "emsdk" inside the usr/local/emsdk directory lead me to the problem. The function here that reports the error:

def update_emsdk():
  if WINDOWS:
    download_and_unzip(urlparse.urljoin(emsdk_packages_url, 'emsdk_windows_upda$
    rmfile('zips/emsdk_windows_update.zip')
  elif OSX:
    download_and_unzip(urlparse.urljoin(emsdk_packages_url, 'emsdk_osx_update.t$
    rmfile('zips/emsdk_windows_update.tar.gz')
  else:
    print 'Unsupported OS, cannot update!'

It's supposed to have an "If" statement for Linux, but doesn't. The offical repo has this function in the same place:

def update_emsdk():
  if WINDOWS:
    download_and_unzip(urlparse.urljoin(emsdk_packages_url, 'emsdk_windows_update.zip'), emsdk_path(), download_even_if_exists=True)
    rmfile('zips/emsdk_windows_update.zip')
  elif OSX or LINUX:
    download_and_unzip(urlparse.urljoin(emsdk_packages_url, 'emsdk_unix_update.tar.gz'), emsdk_path(), download_even_if_exists=True)
    rmfile('zips/emsdk_unix_update.tar.gz')
  else:
    print 'Unsupported OS, cannot update!'

Official SDK Script on GitHub

I still haven't been able to get emscripten working on my linux install, will update if I can figure out a workaround (Simply adding "LINUX" to the if statement didn't work)

I managed to install Emscripten SDK 1.16.0 manually but minko projects still won't compile

Hi,

Yes, the Emscripten SDK didn't support Linux until last week. Please upgrade to the latest SDK. The next beta of Minko will come with support for this new SDK out-of-the-box, but you can already use it.

Regards, Warren.

Ok, you did manage to run Emscripten.

1.16.0 should work flawlessly. Can you make sure you didn't compile a part of the SDK with 1.13.0 and the other one with 1.16.0? Cleaning the repository and rebuilding should do it.

Hello Warren, The 1.16.0 compile was done on a fresh install, there was no 1.13.0 installed beforehand.

Regardless, I cleaned and compiled again with the same result.

Is the next beta getting close?

It's closer than ever :)

It's actually available in the dev branch now.
