fusesoc problems with python on Windows - python3 vs python

[gojimmypi]

similar to #83 in WSL, the Windows version of fusesoc seems to not properly detect which version of python to use.

Here in Windows, python is Python version 3.6 and python3 is not defined, causing a fusesoc error:

Hi,
Check which version of fusesoc you are on through this command fusesoc --version .
Version 1.10 of fusesoc supports python2.7. I am not sure but my best guess is the installed version of fusesoc is not compatible with the installed version of python.

Try this command sudo pip3 install --upgrade fusesoc. As you already have fusesoc, this command will upgrade the older version to a newer one.
If the above command still gives an error, try to install the python3 dependencies then run the above command.

Hope it will do something.

Hi @KinzaQamar - I appreciate your assistance.

I was able to eventually get fusesoc installed, per pip vs `pip3 noted in #83

The `fusesoc`` version on Windows reports:

C:\workspace\myfusesoc>fusesoc --version
1.12.0

but I still see this error:

C:\workspace\myfusesoc>fusesoc run --target=tinyfpga_bx servant

Hi,
Do you have python3 dependencies installed already?

[gojimmypi]

Hi @KinzaQamar - which dependencies are you referring to? The pip3 install fusesoc? Yes.

Here's the output from various commands. I created a new C:\workspace\myfusesoc2 Windows directory to start fresh:

Although it might be nice to get this working on Windows, this issue is not nearly as important since I have fusesoc working on WSL as noted in #83 (comment)

Hmm... this one is a bit tricky. I would had assumed that there would be a python3 symlink/alias on every platform. Especially since we have seen other places where things go haywire because python is linked to python2.

For this particular problem, I see a manual workaround for now. Edit C:\workspace\myfusesoc2\fusesoc_libraries\fusesoc-cores\fusesoc_utils\generators-0.1.7.core and change the interpreter on line 50 from python3 to python. Some context: The servant SoC is using a generator (generators are kind of plugins in the FuseSoC world) to create a PLL with desired frequency settings. This generator is implemented in python, and the core description file for the generator (that you are about to edit) explicitly tells FuseSoC to launch this generator with python3.
