• You need to be able to run the OpenVisualizer, so make sure installed the elements necessary for the OpenVisualizer to run.
• Your computer needs to have gcc installed to be able to compile the firmware as a Python extension module. On Linux, that should be the case by default. On Windows, we recommend http://www.mingw.org/.

• To be able to compile the firmware, the compiler will need to have access to the Python.h header file. If the compiler cannot find it, you will get the following error:

  Code Block

  File "/home/user/Desktop/openWSN-sim/openwsn-fw/SConscript", line 449, in sconscript_scanner scons: done reading SConscript files. scons: Building targets ...

  The Python header files should be present by default on Windows. On Linux, you need to install the python-dev package:

  Code Block
  apt-get install python-dev

• In some Linux installations, you might need to install the python-tk package:

  Code Block
  apt-get install python-tk

Compiling firmware

Before you can run a simulation, you need to compile the OpenWSN firmware as a Python extension module. For that, navigate to the openwsn-fw/ directory, and enter the following command:
