Everything was working fine and I created a nice GUI vcp in qtpyvcp. But after a simple computer restart, I now get the following error when trying to edit my vcp (and similar error if I try to launch the vcp from linuxcnc.)
dave@debianDave:~$ editvcp vcp1
Traceback (most recent call last):
  File "/home/dave/.local/bin/editvcp", line 33, in <module>

I may have overlooked that. Thanks for the suggestion!
However, the xsessionrc command follows the " python3 -m pip install --editable ." command. So I don't get that far.
When trying to issue " python3 -m pip install --editable ." get the following output (with errors):
dave@debianDave:~/qtpyvcp$ pip3 install --editable .

is it possible to start editvcp after you give the Command

export PATH=$PATH:~/.local/bin/

Hello,

there is no vtk in pip for python3.10

i has to be built from sources
```
build vtk python3.10 with QT amd64


$
sudo apt install build-essential cmake mesa-common-dev mesa-utils freeglut3-dev ninja git-lfs

$
git clone --recursive gitlab.kitware.com/vtk/vtk.git

$
cd vtk

$
cmake -B build -S . -GNinja -DVTK_WRAP_PYTHON=ON -DVTK_PYTHON_VERSION=3 -DVTK_ENABLE_WRAPPING=ON -DVTK_GROUP_ENABLE_Qt=YES -DVTK_QT_VERSION=5

$
cmake --build build --parallel 2

#
cmake --install build



build linuxcnc against python3.10 or rebuild if new boost lib in system


install for vtk runtime

libospray libopenvr_api liblas libcgns libadios2_cxx11 libhpdf libboost_python310

run or add this line to your .bashrc
export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python3.10/site-packages/

```

:)

Well, I ran into a few errors.

dave@debianDave:~/dev$ sudo apt install build-essential cmake mesa-common-dev mesa-utils freeglut3-dev ninja git-lfs
[sudo] password for dave:
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package ninja

So I tried the following:
dave@debianDave:~/dev$ sudo apt-get install -y ninja-build
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
ninja-build is already the newest version (1.10.1-1).
 (a bunch of output)

(etc. ... nothing installed...)

Then:
dave@debianDave:~$ git clone --recursive gitlab.kitware.com/vtk/vtk.git
fatal: repository 'gitlab.kitware.com/vtk/vtk.git' does not exist

So I downloaded a zip file from that site, extracted it and then:

dave@debianDave:~/dev/vtk$ cmake -B build -S . -GNinja -DVTK_WRAP_PYTHON=ON -DVTK_PYTHON_VERSION=3 -DVTK_ENABLE_WRAPPING=ON -DVTK_GROUP_ENABLE_Qt=YES -DVTK_QT_VERSION=5

This produced a lot of output but I got the following errors in the end:

CMake Warning at CMake/vtkModule.cmake:4541 (find_package):
  Found package configuration file:

    /usr/lib/x86_64-linux-gnu/cmake/Qt5/Qt5Config.cmake

  but it set Qt5_FOUND to FALSE so package "Qt5" is considered to be NOT
  FOUND.  Reason given by package:

-- Configuring incomplete, errors occurred!
See also "/home/dave/dev/vtk/build/CMakeFiles/CMakeOutput.log".

Can you specify which packages to install to fix this?

I appreciate your help, thanks!!

Hi,


> $ git clone gitlab.kitware.com/vtk/vtk.git
> fatal: repository 'gitlab.kitware.com/vtk/vtk.git' does not exist


try this to get the source and the sub-modules needed to build (zip doesn't include them)

git clone --recursive https://gitlab.kitware.com/vtk/vtk.git


> but it set Qt5_FOUND to FALSE so package "Qt5" is considered to be NOT

plz try to install this ones


$ sudo apt install qtquickcontrols2-5-dev

Well, I got the same errors doing the cmake. I tried to install Qt from source which seems to be the only open source option. It's HUGE! And I got errors when trying to build Qt.

So, I appreciate the advice you've given me. I think I'm just not Linux savvy enough to fix it if something goes off-script.

So I think I'm going to rewind back to Python 3.9 (if I can figure that out...)

Thanks again!
