Castlia 3.3 + omnetpp 4.6 on windows 10

[rim negra]

I have compiled both castalia and omnet and everything waw alright

when running simulation using command line I got these error: 

bash: /c/MyThesis/simulations/omnetpp-4.6/Castalia-3.3/Castalia-3.3/bin/Castalia : /usr/bin/python : mauvais interpréteur: Permission denied

As you see from the message, the problem is that you cannot use /usr/bin/python

Maybe Python is in a different directory in your distribution, or it is not installed properly. This is what you have to resolve.

hi,

did you solve this problem?

 The problem here is that in this shell, Python doesn't exist (the 'permission denied' error is perhaps a bit misleading). Here's what's happening:

- I assume the window in your screenshot is from running MinGWenv.cmd which comes with omnet++. This is a MinGW shell (see http://www.mingw.org/Welcome_to_MinGW_org) which is an amazing tool, which magically provides a minimal GNU build environment (which means you can run build tools like Make) and a Bourne-like shell interpreter (which allows you to reference paths using linux-style /c/MyThesis/whatever instead of windows-style C:\MyThesis\, use bash syntax etc.) all within Windows.

- This is great for building omnet and Castalia on Windows into an .exe, but *it doesn't provide a full linux environment*. Just build tools.

- When you call Castalia, this is asking the shell to run the file called Castalia in the bin folder. The first line of the file is:

#!/usr/bin/python

This tells the shell that to run this file (which is a Pyhton script), you need to use the program called python which is at location /usr/bin. However, this location does not exist on a Windows machine, hence the error.

What you need to do is download Python 2.7 for Windows (https://www.python.org/downloads/release/python-2714/). Easiest is to use the MSI installer. *Make sure you include the 'add python to PATH' feature*. Then open a normal Windows command prompt (i.e. hit 'start key' and enter 'cmd'), cd to the Castalia bin folder, and run:

python Castalia
