Hello,
I have tried reading other threads and have gotten a bit of info and solved a few road blocks but i cant seem to get it working.
To start.
I downloaded the RPI image
www.linuxcnc.org/iso/linuxcnc-2.8.1-pi4.zip
I then ran an axis sim to confirm it works and i have a config directory
I then cloned
github.com/kcjengr/qtpyvcp
into a folder called "qt from source from git"
I then edited setup.py to comment out VTK
I then downloaded and installed
github.com/scottalford75/LinuxCNC-on-RPi...1-qt5py2-1_armhf.deb
Then i modified my .bash.hrc file with
Code:
export PYTHONPATH=/usr/local/lib/python2.7/site-packages:/usr/local/lib/python2.7/site-packages/vtk:$PYTHONPATH
export LD_LIBRARY_PATH=/usr/local/lib:/usr/local/lib/python2.7/site-packages/vtk:$LD_LIBRARY_PATH
then ran
Code:
sudo apt-get install -y notification-daemon
Restarted system
then ran
Code:
sudo apt-get install libhdf5-dev libnetcdf-cxx-legacy-dev libjsoncpp-dev libgl2ps-dev
Then from inside the source directory for Qt i ran "pip install --editable ."
I then copied the configs from the source into linux cnc config.
I can run the QtPyVCP test no problem.
But if i select any other option i get the error "No module named VTK"
I am using this guide as my source for my steps
scottalford75.github.io/LinuxCNC-on-RPi/...20for%20QtPyVCP.html
I feel i may have missed something obvious but i cant find where.
Edit
If i run
Code:
sudo dpkg --list | grep vtk
I get
Code:
libvtk6.3 6.3.0+dfsg2-2+b6
vtk 7.1.1_qt5py2-1
If i run
Code:
"$ python
>>> import PyQt5"
I get no errors
Edit 2
I found that i somehow had pypy2.7 running so i removed it and restarted my system
not sure removing that solved it...
Seems when i run linux cnc from cmd line is the difference.
Now i can get the VTK test to run.
But the open GL test fails with the following
Code:
pi@linuxcnc:~ $ linuxcnc
LINUXCNC - 2.8.1
Machine configuration directory is '/home/pi/linuxcnc/configs/qtdragon'
Machine configuration file is 'xyz-metric.ini'
