"wxPython/Phoenix does not appear to be installed on the system"

Trying to [Slack]build KiCAD 8 (on -current) and I'm getting this failure:

CMake Error at cmake/FindwxPython.cmake:56 (message):
wxPython/Phoenix does not appear to be installed on the system

wxGTK3-3.0.5-x86_64-4_SBo,
wxPython3-3.0.2.0-x86_64-4_SB,
wxPython4-4.2.1-x86_64-1_SBo,
wxWidgets-3.2.4-x86_64-1_SBo
...are all installed.

Anyone have a fix for this?

Try running the commands that cmake runs:

Code:

python

Python 3.12.2 (main, Feb  7 2024, 00:00:00) [GCC 13.2.1 20231205 (Red Hat 13.2.1-6)] on linux

Type "help", "copyright", "credits" or "license" for more information.

>>> import wx

>>> print(wx.wxWidgets_version.split(' ')[1])

3.2.2.1

In your case it seems to be getting an error.

Were the dependencies installed before or after the update to python 3.11?

Traceback (most recent call last):

wxWidgets is installed:

Code:

ls /var/log/packages/ | grep "wx"

wxGTK3-3.0.5-x86_64-4_SBo

wxPython3-3.0.2.0-x86_64-4_SBo

wxPython4-4.2.1-x86_64-1_SBo

wxWidgets-3.2.4-x86_64-1_SBo

So, I tried installing wxpython-4.2.0-x86_64-1alien and it doesn't work either. I still get no module named 'wx'

I removed ALL wxPython packages and reinstalled only AlienBOB's package and did a reboot with no effect.

Every dependency that I can find listed has been BEFORE the update.

Two things

Python 3.12.2 ,

why ?

slackware provides python-3.11 not 3.12

And , second thing , if you have installed wxpython etc etc etc , okey ..but , probably installed when you have python 3.9 ?

You need to rebuild ALL , of the python things to sync with the version installed.

That wasn't my box. My box the default Slackware package on it:

Code:

Python 3.11.9 (main, Apr  2 2024, 13:43:44) [GCC 13.2.0] on linux

Type "help", "copyright", "credits" or "license" for more information.

I reinstalled all of it, no affect. I'm even running AlienBOB's wxPython package.

The REAL question is, why isn't python seeing the wxPython? How does it detect these things?

When you say "reinstalled all of it", do you mean A) "rebuilt and reinstalled the packages" or B) "downloaded and reinstalled the packages"?

If you did B), it won't work because AlienBOB's wxPython package was built with Python 3.9 (just look inside the package file, there will be many files installed in python 3.9 directories)
As suggested by USUARIONUEVO, you have to rebuild the packages on your Slackware machine with Python 3.11 and then install those packages.

I"m no python expert, but my impression is that:

Mixing installation of python modules by system commands or SlackBuild versus python's pip can lead to confusion.
When using pip as a normal user, modules will be built/installed within the user's space and only available to the user. (e.g. ~/.local/lib/python3.9/site-packages)
Using pip as root will install things in places where all users can access them. (e.g. /usr/lib64/python3.9/site-packages
...but python modules get installed in directories that are specific to the version of python (2.7, 3.9, 3.11 etc) that pip is part of. (Slackware has pip, pip2, and pip3 in /usr/bin, to give some control over whether you are installing for python2 or python3.) As a result, installing modules for python 2.7 won't help python 3.x,and things installed for python 3.9 are ignored by python 3.11.

Trying to figure out where python has actually found a module has always been confusing to me. It has a defined search order, but there does not seem to be an easy method in code to determine the point at which the search succeeded. (Well, at least, easy for me.)

arfon, check for installed packages built for python3.9:

Code:

grep -l -m 1 python3.9 /var/log/packages/*|cut -d/ -f5|rev |cut -d- -f 4- |rev

Code:

/usr/lib/python3.11/site-packages/setuptools/__init__.py





## for wxPython4 and showing version

python3 -c "import wx as i; print(i.__file__,i.__version__)"

To make wxpython work in Slackware current, I built the following packages from source using AlienBOB slackbuild scripts (adapted to match newer versions and source file tar format in some cases instead of tar.gz).

- python-pathlib2 2.3.7.post1
- python-attrdict 2.02
- wxpython 4.2.1

Install the first two packages before building wxpython.

wxpython build will fail with :

Code:

:info:build Compiling wx/svg/_nanosvg.pyx because it changed.

:info:build [1/1] Cythonizing wx/svg/_nanosvg.pyx

:info:build Error compiling Cython file:

:info:build ------------------------------------------------------------

:info:build wx/svg/_nanosvg.pyx:45:8: 'cython.object' is not a valid cython.* module

This is solved by patching source file wx/svg/_nanosvg.pyx by removing this line:

Code:

cimport cython.object

See https://github.com/wxWidgets/Phoenix/issues/2514
Patch: aeb557d

Note: I patched the above source file the quick and dirty way (I'm not so good at patching file). I'm sure someone can show the proper way to apply this patch in the wxpython Slackbuild

Everything builds fine here, this is the sbopkg log. kicad seems to run fine too.

The REAL question is, why isn't python seeing the wxPython? How does it detect these things?

To answer your question, the "python" program looks in /usr/lib64/python$PYTHON_VERSION/ folder for it's modules. This means that you can have multiple python versions installed alongside each other, each with their own set of modules. This is because python's minor version keeps changing, so a module written for 3.9 may not work with 3.11.

This means that Pat's upgrade to 3.11 broke the entire python universe on Slackware, forcing everyone to go through and re-run the SlackBuild scripts for every single module. Reinstalling isn't enough. A 3rd party repo like alienbob's is going to lag for some time until he gets a chance to update everything. As others here have mentioned the solution is to rebuild the packages you need yourself or wait for the repo you use to catch up.

Python is so much fun......

Latest error:

Code:

-- Found wxPython Phoenix 4.2.1/gtk3 (wxWidgets 3.2.2.1)

CMake Error at /usr/share/cmake-3.29/Modules/FindPackageHandleStandardArgs.cmake:230 (message):

  cmake/FindwxWidgets.cmake:987 (find_package_handle_standard_args)

  CMakeLists.txt:1001 (find_package)

The part I don't understand:

Code:

  Could NOT find wxWidgets (missing: wxWidgets_LIBRARIES

  wxWidgets_INCLUDE_DIRS) (Required is at least version "3.2.2.1")

When it said (before that):

Code:

-- Found wxPython Phoenix 4.2.1/gtk3 (wxWidgets 3.2.2.1)

So after removing ALL of the python and wx packages and reinstalling them from -current/Alien/SBo. It still didn't work.

In the end, my issue was that I had AlienBOB's wxGTK3 3.2.1 package on the machine with the wxWidget 3.2.4 SBo package. It would 'see' the correct wxGTK3 version from the SBo but, it would try and load the wrong one from AlienBOB.

Got rid of the wxGTK3 3.2.1 package and now KiCAD builds.

What a PITA
