2.9 Install Help was created by servocnc
I'm a new LinuxCNC user that's trying to work on a migration off of Mach3.  I'm good with computers and programing, but not with Linux, and I'm getting very frustrated with it - just be aware...  I've used Linux off an on over the last 20 years and like the end result, but hate getting there every time...

I used the ISO and got an instance of 2.8 working on my machine with the parallel port.  I liked QTDragon and would like to try out QTDragon HD, which requires 2.9 effectively (best I can tell).  I'll also note that I'll probably try PathPilot down the road, but I want to get things worked out with QTDragon HD first.  To assist in this move, I'll be adding a Mesa 7i92H soon, but for now I'm just trying to get the software installed / working.

So, I tried upgrading my Buster / 2.8 install to 2.9, and that failed miserably.  I had over a hundred dependencies that I couldn't figure out how to resolve, so I started looking for other options.  Here on the forum, I found the sticky for installing 2.9 on Mint (forum.linuxcnc.org/9-installing-linuxcnc...ter-on-linux-mint-21), so I've tried that.

I have Mint installed, and LinuxCNC 2.9 works in Axis.  But I can't get it to work with QTDragon (any of them).  I first had errors that PYQT5 was missing, so I got that installed (sudo apt-get install python3-pyqt5).

Now, when I run LinuxCNC with any of the QTDragons, I get this error:

Traceback (most recent call last):File "/usr/bin/qtvcp", line 511, in <module>APP = QTVCP()File "/usr/bin/qtvcp", line 133, in __init__from qtvcp import qt_makepins, qt_makeguiFile "/usr/lib/python3/dist-packages/qtvcp/qt_makepins.py", line 22, in <module>from qtvcp.widgets.screen_options import ScreenOptionsFile "/usr/lib/python3/dist-packages/qtvcp/widgets/screen_options.py", line 24, in <module>from qtvcp.lib.message import MessageFile "/usr/lib/python3/dist-packages/qtvcp/lib/message.py", line 5, in <module>from qtvcp.widgets.dialog_widget import LcncDialogFile "/usr/lib/python3/dist-packages/qtvcp/widgets/dialog_widget.py", line 32, in <module>from qtvcp.widgets.macro_widget import MacroTabFile "/usr/lib/python3/dist-packages/qtvcp/widgets/macro_widget.py", line 86, in <module>class CustomSVG(QtSvg.QSvgWidget):NameError: name 'QtSvg' is not defined

When I hit "Retry", I then get the normal LinuxCNC Errors window:

I've googled as best I know how and haven't found any solutions related to LinuxCNC.  I'm sure it's something simple, but I don't know how to fix it.  Hopefully someone here does...

Thanks,

Danny

Well, made progress based on your suggestion, so thanks for that.

For newbies like me, what I did was:

cd /usr/lib/python3/dist-packages/qtvcp/designer/

sudo bash install_script

When prompted, I chose option #3 for package install (I guessed).


The base QTDragon now appears to work. But when I choose QTDragon HD, I get the QTVCP error window once it's loaded:

Traceback (most recent call last):File "/usr/lib/python3/dist-packages/qtvcp/widgets/round_gauge.py", line 54, in paintEventself.draw_zones(painter, event, w)File "/usr/lib/python3/dist-packages/qtvcp/widgets/round_gauge.py", line 84, in draw_zonesrect.setSize(QSize(w/2, w/2))TypeError: arguments did not match any overloaded call:QSize(): too many argumentsQSize(int, int): argument 1 has unexpected type 'float'QSize(QSize): argument 1 has unexpected type 'float'


And after I hit "Abort" ("Retry" doesn't change anything - the error pops right back up) then I get the normal Linux CNC error box that contains:

I haven't researched this one yet, but Ifigured I'd post my progress here for future reference...

OK, I'm stuck. I've searched and everything associated with these errors seems to be programming bugs and nothing related to LinuxCNC. Anyone have any ideas?

Moved to "Qtvcp" section.
Those all seem QT errors, so might get more help here.

This looks like it is because the latest pyqt library changed function signature types.

can you;
open a terminal and type:
python3

then:

from PyQt5.QtCore import QT_VERSION_STR, PYQT_VERSION_STR
print("Qt: v", QT_VERSION_STR, "\tPyQt: v", PYQT_VERSION_STR)

And post what it prints.

Danny.
I'm 99% sure that version has the changes that break out code.
Unfortunately I don't have a system that uses the new library so can't current test.
I have fixed the errors as best I can as they are reported.

I see errors from round_gauge in your post so will look at he code and see if I can fix it.

Ok, good to know it's not something I did wrong.

Is there a work-around? Can I downgrade something somehow for instance?

Thanks for the help,

I pushed a fix for that particular error.
So you could try checking for linuxcnc updates.
I know no way to downgrade the pyqt version on the system.
Only by using an older distribution.
