Install the v5.99 python modules?

Drew_Fustini · January 7, 2021, 2:27am

I run KiCad v5.99 built locally from the git repo. I am trying to figure out how to install the corresponding Python libraries as have old v5.1 version for the Ubuntu package. I can’t see to figure out what make target will do that. Thanks!

Details:

This is the v5.1 version that comes from the Ubuntu package:
pdp7@x1:~/dev/kicad/kicad/build/debug$ find /usr/lib |grep -i pcbnew
/usr/lib/python3/dist-packages/pcbnew.py
/usr/lib/python3/dist-packages/_pcbnew.so
pdp7@x1:~/dev/kicad/kicad/build/debug$ python3

[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pcbnew
>>> print(pcbnew)
<module 'pcbnew' from '/usr/lib/python3/dist-packages/pcbnew.py'>
>>> 

pdp7@x1:~/dev/kicad/kicad/build/debug$ dpkg -L kicad |grep python

Here is the v5.99 install:

pdp7@x1:~/dev/kicad/kicad/build/debug$ which kicad

Here is the v5.99 build dir:

pdp7@x1:~/dev/kicad/kicad/build/debug$ find |grep py$
./pcbnew/pcbnew.py

Drew_Fustini · January 7, 2021, 3:51am

I tried:

$ export PYTHONPATH=$HOME/dev/kicad/kicad/build/debug/pcbnew

$ ls $PYTHONPATH 
altium2kicadpcb_plugin  connectivity         docstrings  pcad2kicadpcb_plugin  pcbnew.py   pcbnew_wrap.cxx  router

But I failed to import pcbnew:

craftyjon · January 7, 2021, 4:12am

I have not seen that error before. It works for me with Python 3.7.3. Do you have KICAD_SCRIPTING_PYTHON3=ON in your CMakeCache.txt?

$ cat test.py
#!/usr/bin/env python3

import pcbnew

print(pcbnew.GetBuildVersion())

$ PYTHONPATH=$HOME/work/kicad/build/debug/pcbnew python3 test.py
(5.99.0-8218-g0234b7278a)

Drew_Fustini · January 7, 2021, 4:16am

Ah! Looks like I have it off:


//Build for Python 3 instead of 2 (default OFF).
KICAD_SCRIPTING_PYTHON3:BOOL=OFF              

//Build wxPython implementation for wx interface building in Python
// and py.shell (default ON).
KICAD_SCRIPTING_WXPYTHON:BOOL=ON

//Use new wxPython binding (default OFF).
KICAD_SCRIPTING_WXPYTHON_PHOENIX:BOOL=OFF

craftyjon · January 7, 2021, 4:17am

Turning that on should do the trick. From a quick search, it looks like that error is typical of building for Python 2 and running on Python 3

Drew_Fustini · January 7, 2021, 4:48am

I have run into this error now:

Looks like this might be a problem:

Drew_Fustini · January 7, 2021, 5:05am

@craftyjon is there a way for me to tell it to use Python 3?

I tried this:

nickoe · January 7, 2021, 7:37am

It is safer to make a clean configure, meaning you specify to enable python3 and phoenix at the first configure.

craftyjon · January 7, 2021, 2:45pm

Yeah, it is probably something cached by CMake already. I’m not sure the details of how the python finder works, but probably it has set a number of variables for Python2 already.

Drew_Fustini · January 7, 2021, 9:21pm

Add -DKICAD_SCRIPTING_WXPYTHON_PHOENIX=ON

Drew_Fustini · January 7, 2021, 9:27pm

If I do that, then I get issue:

-- Python module install path: lib/python3/dist-packages
CMake Error at CMakeLists.txt:810 (message):
  Unable to find wxPython Classic, instead found wxPython Phoenix 4.0.7

I switched it to off and cmake completed. For now, I am ok with no in-app scripting console.

qu1ck · January 7, 2021, 11:27pm

You have to clean cmake cache again after adding -DKICAD_SCRIPTING_WXPYTHON_PHOENIX

Drew_Fustini · January 8, 2021, 3:36am

I’ve not pursued getting WxPython to work, but I can import pcbnew from v5.99 now ok:

which shows me that it seems we will need to update our CAM script for V6.

craftyjon · January 8, 2021, 3:41am

@Seth_h is it stable enough for fabs to start doing this, do you think?

Seth_h · January 8, 2021, 2:14pm

I don’t think so yet.

Drew_Fustini · January 17, 2021, 9:53pm

I just realized that KICAD_SCRIPTING_WXPYTHON=OFF seems to mean I can’t run any plugins ( V5.99: plugins missing after recent build ) so I do need to find a solution to getting past the error when KICAD_SCRIPTING_WXPYTHON=ON:

pdp7@x1:~/dev/kicad/kicad/build/debug$ cmake -DKICAD_SCRIPTING_WXPYTHON=ON -DKICAD_SCRIPTING_PYTHON3=ON -DCMAKE_BUILD_TYPE=Debug -DCMAKE_PREFIX_PATH=/usr/local -DKICAD_CONFIG_DIR=kicad-master ../../

What error do you get if you put -DKICAD_SCRIPTING_WXPYTHON_PHOENIX=ON instead of -DKICAD_SCRIPTING_WXPYTHON=ON?
