Install GladeVCP on Raspberry Pi 4

Hi everyone,

Since last week I am using a Raspberry Pi 4 Model B 4GB, and I am using the LinuxCNC distribution from  this post.

Unfortunately I have not yet succeeded in installing GladeVCP, does anyone perhaps have some advice for this?
I have tried to install glade-gtk2 and glade-3, but both resulted in an error message, see the attached screenshot.

Hopefully it is possible to solve this issue, as I would very much like to get started with building custom GUI's that are able to execute Python scripts.

Its not clear to me which Debian version you have installed and which LinuxCNC version. But that is important.

Hi HansU, thank you for the quick reply.

I am running Debian 12 with LinuxCNC version 2.10.0-pre0.
When I type "uname -a" in the terminal the response is: Linux raspbook 6.0.15-rt14-v8+ #1 SMP PREEMPT_RT

Would this information be sufficient?

I think the problem is related to the fact that the operating system is for arm64 while the libraries to install are for 32 bit (armhf)

Not sure if glade is available in the package sources for arm64.

However glade-gtk2 is not the right one for Linuxcnc 2.9 / Gtk 3.
Its just 'glade' now.  I guess you installed that when meaning 'glade-3' ?

Thank you Elovalvo and HansU for your comments.

As I got completely stuck with installing GladeVCP, I installed a different RPi image on my SD card. It’s Debian 12, I followed the instructions from this file:  docs.google.com/document/d/1S0K-UBlXnsYC...4BIzSBl7-o10b_0/edit

Instead of trying to install 'glade-gtk2' or 'glade-3', I just installed 'glade'. The version is 3.40.0.
After this, I copied all the files from /usr/share/glade3/ to /usr/share/glade/.

The first image below shows a very simple user interface that I tried to test, just a window with a HAL_LED.
When I try to execute the command, while LinuxCNC being opened (see second image), I get an error “AttributeError: ‘NoneType’ object has no attribute ‘set_title’”

If you have any suggestions that I could try in order to get this solved I would of course be very happy to hear them.

The name of your GtkWindow is "window", right? It has to be "window1". Documented here: www.linuxcnc.org/docs/2.9/html/gui/glade...a_new_user_interface

Thank you for your quick help!
Although I read the documentation while I was installing it, I did not understand that part as I couldn't find anything in Glade that mentions "window1". But as the documentation describes that this is the default anyway I thought it would not cause any issue.
However, if I would need to change "window" to "window1" as you mentioned it would be of importance of course.

I searched for it again but I have not been able to find anything that mentions either "window" or "window1". (I only see it in the documentation screenshots, but Glade looks very differently on my device.)
Do you perhaps refer to the "Widget name" field in the "Common" tab? Or perhaps does it refer to the "ID" field in the "General" tab?
Both fields are empty by default, but if I enter "window1" the error still persists.

It should be the id in the General tab:

By default the "ID" field in the "General" tab was empty, but after I entered the text "window1" in this field the error stays the same unfortunately.
