KiCad 6: Error in pcbnew when calling `plotpcb` (create wxApp before calling this)

[edahlseng]

I'm trying to run plotpcb, but getting an error in what I think is the pcbnew library. I'm seeing the following error message printed out multiple times:

./src/common/stdpbase.cpp(59): assert ""traits"" failed in Get(): create wxApp before calling this

Do you know what might be causing this?

[Gasman2014]

What version of KiCad are you running? I have not been testing this against 5.99 yet

[edahlseng]

Ah, yes, this is against 5.99.

[Gasman2014]

Yeah, the Python API has been in a state of flux in 5.99 - tbh I haven't tried to fix this until it was a bit more stable. The diff only needs access to the plotting routines which should be exposed without creating a wx interface, so (hopefully) should be an easyish fix. I'll try and take a look at this a bit later.

[leoheck]

@edahlseng check if this helps you with something https://github.com/Gasman2014/KiCad-Diff/issues/55

[edahlseng]

I tried this again now that KiCad 6 is out, but it looks like it's still failing. I see what I think may be a new error line before the error messages I mentioned earlier (though very similar):

Plot1 error: ./src/common/stdpbase.cpp(59): assert ""traits"" failed in Get(): create wxApp before calling this

[leoheck]

OS?

[leoheck]

It works for me on Linux. I also have some changes to push I am just not sure if they change much. I am also using another solution to fix the generated svg images since the SVG generated by Kicad is not well-formed.

[edahlseng]

macOS. I think I saw in another issue comment that @Gasman2014 was also having issues with macOS. Interestingly, I think that earlier 5.99 versions of KiCad from a couple of months ago were generating images properly despite the error messages. With v6, that no longer appears to be the case. If anyone has pointers on where to look for this I’d be happy to poke around.

[leoheck]

plotPCB.py has the macos path hardcoded. It may be related. What is the output running this command? Replace the [board_name] with yours, please.

plotpcb [board_name].kicad_pcb

[edahlseng]

I'm installing with this method, which runs plotpcb under a virtual environment created from the KiCad bundled python.

Here's what I get when running that command:

I do see SVGs being created for all of the layers, but they're all blank SVGs.

Dude, please. What is the name of your board? This does not look right. Review my message. Also review the command, please.

If anyone has pointers on where to look for this I’d be happy to poke around.

I feel it happens on linux too. Svg from Kicad plotter is not well-formed I think. You could file a bug report.

Also, try this branch to see if it improves something for you. BUT FIRST, try to fix the command above. Your board is not [board_name] unless you are playing a trick on us. https://github.com/leoheck/KiCad-Diff/tree/improve-svg

To try svg optimization you will have to install svgo and have it available in our PATH And you will have to call kidiff or plotpcb with -x

[edahlseng]

Also, try this branch to see if it improves something for you. BUT FIRST, try to fix the command above. Your board is not [board_name] unless you are playing a trick on us.

No tricks, I just redacted the board name from my output. Everything I pasted above is an exact copy-and-paste from what I ran, except I replaced my actual board name with [board_name].

[leoheck]

Dude, focus, please, is it working or not? Does it help or not? What is the output of the command with the right board name?

[edahlseng]

Dude, focus, please, is it working or not? Does it help or not? What is the output of the command with the right board name?

Please re-read my previous two messages. The output I pasted above was run on an existing board, I just redacted what I posted. The tool is not working, as only blank SVGs are being output.

[leoheck]

I see. I don't have a macOS and this looks like a specific issue with macOS. On Linux it kind of working. It is not perfect I think, but it does not give me those messages. Have you reported this on Kicad's GitLab or posted this on Kicad forum?

[edahlseng]

I have not yet, but I can! Do you have any pointers into this codebase on key lines that I could pull out into a minimally reproducible example to post?

[leoheck]

Post your issue in the Forum first to start this discussion. Maybe someone knows how to fix this. Or file a report directly in Gitlab exactly as you are doing here. I don't have this issue. I am not a macOS user. If you post the forum post or GitLab issue here, I bet John may joining to the discussion too.

[leoheck]

Kicad 6.0.1 was released. Could you check if this is still happening there?

[leoheck]

I also see some messages but the files are being generated, as you can see.

[leoheck]

This is Kicad's version I have installed 6.0.1-79c1e3a40b~116~ubuntu21.10.1

[leoheck]

@edahlseng this branch was improved a bit. It is working for me on a Macbook Air (M1) as you can see the screenshot here https://github.com/leoheck/KiCad-Diff/tree/improve-svg

I don't think it needs the new Kicad 6.0.1 but it is to to upgrade it anyways.

[Gasman2014]

Just been looking at the codebase and see that JPCharras merged this a couple of weeks ago which might address the svg rendering issues. It seems to set the default svg precision to 4 digits in the mantissa and I think the overflow might be causing problems.

At present, I can only get good rendering in Chrome. Firefox is sort of OK (as you show above) and Safari is still broken. setSvgPrecision doesn't seem to work, whatever I do.

Use 4 digits in mantissa as default and when exporting SVG.
Allow 0 as line width: this is the right value to draw filled shapes with no outline thickness.

https://gitlab.com/kicad/code/kicad/-/blob/master/pcbnew/pcb_plot_params.cpp

I think there will be a 6.0.2 (and prob a 6.0.3 bug fix) - I hope but am not sure if this will make the cut.

FWIW I was also going to reformat everything so that its PEP8 compliant.

[leoheck]

The fix or workaround from Kicad team would be better because the fix I created is not good at all, it is a nonsmart fix that may fail sometimes. To properly fix it I would be required to use a SVG parser instead. And also, it is being applied with an external script. It would be better to have this implemented in python directly.

Allow 0 as line width: this is the right value to draw filled shapes with no outline thickness.

This comment here may be something interesting to play with. The line width function changed its name, and maybe its functionality from the previous Kicad.

@Gasman2014 can we work to merge my last PR before we do this PEP8 thing? I can also apply the PEP8 if you are ok with it, after. I did not do that before because PEP8 is pretty rigorous, and a bit annoying sometimes, but it may support a config file that we can customize its behavior a bit.

[leoheck]

@Gasman2014 Kicad 6.0.2 is already available https://www.kicad.org/blog/2022/02/KiCad-6.0.2-Release/. Tried here removing my workarounds and it still does not work for Firefox. It may not work for Safari too.

[Gasman2014]

I have just downloaded it but not having any more success with this yet.

Could you update me, when possible, with the issues you are having?

[Gasman2014]

OK, so running on Monterey / KiCad 6.0.2.

So, Ive tried with the Master branch, which seems to work OK but the rendering issues still persist so have obviously not been fixed in KiCad. The svgs are still only viewable using Chrome. Rendering issues as previously described with Firefox & Safari persist.

Now, I have checked out the head of the leoheck-wxwidges_and_pcm branch.

Now, the wx thing is really pi%%^%ing me off. I have a conda environment with python 3.8 and wxPython.

% which pythonw /Users/johnpateman/opt/miniconda3/envs/kd/bin/pythonw

All ok ;)

% pythonw Python 3.7.11 (default, Jul 27 2021, 07:03:16) [Clang 10.0.0 ] :: Anaconda, Inc. on darwin Type "help", "copyright", "credits" or "license" for more information.

So, pythonw seems to be working…

But don’t speak too soon...

% ./kidiff.py This program needs access to the screen. Please run with a Framework build of python, and only when you are logged in on the main display of your Mac.

pythonw kidiff.py This program needs access to the screen. Please run with a Framework build of python, and only when you are logged in on the main display of your Mac

And the same if I replace the shebang with the known, working pythonw.

Also tried with a brew installed wxPython (as you suggested).

Also tried using the KiCad provided python

/Applications/KiCad/KiCad.app/Contents/Frameworks/Python.framework/Versions/3.8/bin/python3 kidiff.py This program needs access to the screen. Please run with a Framework build of python, and only when you are logged in on the main display of your Mac.

Ok, I am going to create a new user on my macOS to see if I can reproduce this.

Now, you are running it a bit differently than what I am expecting. I recommend you to setup the environment first, and then call kidiff with the kidiff (bash script) that is going to be available in your PATH.

Why? Because it is going to call it using the Python interpreter that comes with Kicad (as we used to do). Maybe that python has something different than the system's interpreter that is indicated by the the kidiff.py file

[Gasman2014]

Yes, I set up a completely new Conda environment.

conda create --name "KD" python=3.7 wxpython

I couldn’t create a Conda environment including wxPython with python >3.7 though. Not sure if that’s significant. Anyhow, when I activate the KD environment, pythonw works fine.

Why? Because it is going to call it using the Python interpreter that comes with Kicad (as we used to do). Maybe that python has something different than the system's interpreter that is indicated by the the kidiff.py file

Tried that too - and not working either...

What I thin is worth looking at is how QUICK1’s InteractiveHTMLBOM works.

The only thing I could find is that our first line uses env. QUICK1’s uses python3 directly. Can you test changing this while I don't have the environment ready?

[leoheck]

On macos even the Finder cannot preview the right content of the generated file. This is something Kicad team does not know.

This should be the content of the selected file

[leoheck]

@Gasman2014 I improved the file picker a bit that was not pretty good for me on macos. Also, fixed the workaround that fixed svg for macos. It is working better on Safari. But the main diff window is still not being displayed. Still could not close that small window. And I could not recreate your issue here yet.

[Gasman2014]

Tried that too - no dice. I’ve just reinstalled miniconda and am trying to set up a completely new environment on my new MBP M1 and now have even more issues as conda won’t install wxPython at all. Might go back to brew.

I created a new user. Had to install brew again. I cloned the repo. Loaded the environment with source env.sh and could not see the issue.

This is the best I could do on this mac, since I cannot format it. I have others Macbooks at my work, that I can format but this will take some times, since I am in quarantine recovering from Covid.

But we could try to compare some environment settings. Can you share the output of some commands so we can try to identify differences?

This is the output of the command env

This is which python, python3 and pythonw

lheckk@pipinho KiCad-Diff % which python3

These are the versions of each of these things

lheckk@pipinho KiCad-Diff % python --version
Python 2.7.18
lheckk@pipinho KiCad-Diff % python3 --version
Python 3.9.10
lheckk@pipinho KiCad-Diff % pythonw --version
Python 2.7.18

This compare the paths to see if they are symbolic links and if they point to the same file

lheckk@pipinho KiCad-Diff % ls -ltr $(which python)
lrwxr-xr-x  1 root  wheel  75 Feb  6 18:22 /usr/bin/python -> ../../System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7

lrwxr-xr-x  1 root  wheel  76 Feb  6 18:22 /usr/bin/pythonw -> ../../System/Library/Frameworks/Python.framework/Versions/2.7/bin/pythonw2.7

Launching kidiff only, launches the Finder showing only project files. This is nice.

Then the commit selection window (this is still ugly, but did not try to improve it for Mac, yet)

Then this is Safari working just fine with the fixed version of the workaround

Here the triptych

[Gasman2014]

Thanks Leandro - I’ll look into this later today. Which version of macOS are you running? I’m now on Monterey on an M1 but I should be able to access a MBP running Catalina to compare.

Hey John, Here with me it is the same version. M1 running the latest Monterey. I also installed it when the machine was pretty clean. This means I installed brew and wxwidgest at the same time. The interesting thing here is that my python3 is the one from homebrew while python (2.17) and pythonw are pointing to the same binary, so they are the same thing. But KicadDiff uses python3. When you have a chance, check from where your python3 comes.

[Gasman2014]

Not in front of my machine but I did a time machine transfer from Catalina on MBP to M1. I then reinstalled brew - as the old path was /usr/local and is now /opt/homebrew. I also updated miniconda which is now ~/miniconda and not ~/opt/miniconda. Python3 points to the miniconda version. I have a brew installed Python which I have tried by simply deactivating conda.

Will check everything again later.

So, with the ‘base’ environment active via conda, I get the same conda installed Python 3.8.11 by invoking ‘python’, ‘python3' or ‘pythonw'

If I deactivate conda, I get the system installed python & pythonw version 2.7. I need to specify python3 to get the ‘brew’ installed version.

ah, this seems to be a good test then, forcing use brew's version. let's see if this helps.

Not in front of my machine but I did a time machine transfer from Catalina on MBP to M1. I then reinstalled brew - as the old path was /usr/local and is now /opt/homebrew. I also updated miniconda which is now ~/miniconda and not ~/opt/miniconda. Python3 points to the miniconda version. I have a brew installed Python which I have tried by simply deactivating conda.

Will check everything again later.

 Hey John, Here with me it is the same version. M1 running the latest Monterey. I also installed it when the machine was pretty clean. This means I installed brew and wxwidgest at the same time. The interesting thing here is that my python3 is the one from homebrew while python (2.17) and pythonw are pointing to the same binary, so they are the same thing. But KicadDiff uses python3. When you have a chance, check from where your python3 comes.

What does it show for which pythonw after disabling conda? Also, I forget to check, which versoion is used when I call kidiff directly.

Can you add this in your kidiff.py and launch it to see what it is going to show.

import sys
print(sys.version)

I think a good place to put this is in the first line under the __main__()

[Gasman2014]

%  which pythonw /usr/bin/pythonw 22:23:55  johnpateman  Applications  KiCad  %  pythonw -V Python 2.7.18

But we call

/usr/bin/env python3

I’m going to PM you my env via the Forum as I don’t want to post it here.

Fair, you can also remove some lines that are sensitive if you feel that they don't contribute to this issue.

[leoheck]

Check this line here

From here, https://wiki.wxpython.org/wxPythonVirtualenvOnMac

You may have been running an initial build of a tool. You mention that you have synced or upgraded your mac with an old install right? I always do a clean install, and this may be happening because of that. Now, how do we fix this?

[leoheck]

I am also using the same version

➜ kidiff board.kicad_pcb -r
/opt/homebrew/opt/python@3.9/bin/python3.9
3.9.10 (main, Jan 15 2022, 11:40:53) 
[Clang 13.0.0 (clang-1300.0.29.3)]

I also added this line print(sys.executable) to check from where the interpreter is comming.

[leoheck]

These are the relevant brew things I have installed to make this work.

➜ history | grep brew
    3  brew update
    4  brew upgrade
  204  brew install scour
  325  brew install wxwidgets
  341  brew install wxpython
  427  brew install librsvg
  432  brew install gsed
  458  brew install dos2unix

[leoheck]

These are all brew things I have installed

➜ brew leaves | xargs -n1 brew desc

dockutil: Tool for managing dock items
dos2unix: Convert text between DOS, UNIX, and Mac formats
gh: GitHub command-line tool
git: Distributed revision control system
gnu-sed: GNU implementation of the famous stream editor
librsvg: Library to render SVG files using Cairo
scour: SVG file scrubber
wxpython: Python bindings for wxWidgets
wxwidgets: Cross-platform C++ GUI toolkit

I would ask you to reinstall python3 too

brew reinstall python3 

For some reason I got this msg, maybe I have installed it with sudo by mistake. I had to fix the issue with the following instructions

Error: The following directories are not writable by your user:
/opt/homebrew
/opt/homebrew/share/zsh
/opt/homebrew/share/zsh/site-functions
/opt/homebrew/var/homebrew/locks

You should change the ownership of these directories to your user.
  sudo chown -R $(whoami) /opt/homebrew /opt/homebrew/share/zsh /opt/homebrew/share/zsh/site-functions /opt/homebrew/var/homebrew/locks

And make sure that your user has write permission.
  chmod u+w /opt/homebrew /opt/homebrew/share/zsh /opt/homebrew/share/zsh/site-functions /opt/homebrew/var/homebrew/locks

[leoheck]

Ah, reinstall these 2, too

brew resintall wxwidgets
brew reinstall wxpython

[leoheck]

Do not forget these 2

brew update
brew upgrade
