For some reasons I have to switch to Ubuntu 26.04 Unfortunately ptgui failed on my 26.04 Installation.

Clean and fresh Installation Ubuntu LTS 26.04 
Downloaded PTGui_13.7.tar.gz
then:
cd Downloads
sudo tar xvfz PTGui_13.7.tar.gz
cd ptgui_13.7
sudo chmod +x install.sh
sudo ./install.sh

PtGui seems to be installed but does not start. 
Any Idea what I can try else?

Hi Rainer,

PTGui might fail to start due to a missing package in your ubuntu
installation. An error will be logged to the systemd user log.

Could you try running PTGui from the command line? Any errors will be
displayed in your terminal.

cd ptgui_13.7 (or to the directory where you unpacked)
./PTGui

The latter command will launch PTGui.

PTGui does need an opencl environment. On ubuntu this is provided by one
of these packages:
mesa-opencl-icd
ocl-icd-libopencl1

Kind regards,

Hi Joost

If I start PTGui as mentioned I got:
./PTGui: error while loading shared libraries: libGLU.so.1: cannot open shared object file: No such file or directory

libgtk-3-0t64 is the newsest Version (3.24.52-0ubuntu1)

Hi Joost

If I start PTGui as mentioned I got:
./PTGui: error while loading shared libraries: libGLU.so.1: cannot open shared object file: No such file or directory

solved it with
sudo apt update && sudo apt install libglu1-mesa

sudo apt install libgtk-3-0, gives the answer

libgtk-3-0t64 is the newsest Version (3.24.52-0ubuntu1)

now I can start PTGui


best Rainer
