Hi, Im getting the following error when trying to run on Ubuntu 20 while following the instructions in the Readme

$ onvif-gui Traceback (most recent call last): File "/home/user/Personal/Tryout/libonvif/onvif-gui/myvenv/bin/onvif-gui", line 5, in from gui.main import run File "/home/user/Personal/Tryout/libonvif/onvif-gui/myvenv/lib/python3.10/site-packages/gui/init.py", line 1, in from .main import MainWindow File "/home/user/Personal/Tryout/libonvif/onvif-gui/myvenv/lib/python3.10/site-packages/gui/main.py", line 42, in from gui.panels import CameraPanel, FilePanel, SettingsPanel, VideoPanel, AudioPanel File "/home/user/Personal/Tryout/libonvif/onvif-gui/myvenv/lib/python3.10/site-packages/gui/panels/init.py", line 1, in from .camerapanel import CameraPanel File "/home/user/Personal/Tryout/libonvif/onvif-gui/myvenv/lib/python3.10/site-packages/gui/panels/camerapanel.py", line 26, in from gui.onvif import NetworkTab, ImageTab, VideoTab, PTZTab, SystemTab, LoginDialog, \ File "/home/user/Personal/Tryout/libonvif/onvif-gui/myvenv/lib/python3.10/site-packages/gui/onvif/init.py", line 7, in from .datastructures import Session, StreamState, MediaSource, Camera File "/home/user/Personal/Tryout/libonvif/onvif-gui/myvenv/lib/python3.10/site-packages/gui/onvif/datastructures.py", line 41, in class Session(onvif.Session): AttributeError: module 'libonvif' has no attribute 'Session'

Hello, thank you so much for reaching out. It would appear from the error message that libonvif has failed to compile. In most cases, this is due to a dependency problem, either not installed or some kind of version mismatch. The dependency in this case would be libxml2. You can verify installation using the command

apt list --installed | grep libxml2

You should get a response showing the version installed. If there is a good libxml2 installed, navigate to the libonvif root directory and use the command

assets/scripts/compile

There will be a long output that shows the internal messages generated by the compiler. Near the top should be a section showing the output of the libonvif compile. If there has been a failure, the error message will show specifics.

Please let me know what those messages are, and I can have a better idea of what to do to fix the install.

Hi Thanks for the quick response @sr99622!. libxml2 version

$ apt list --installed | grep libxml2

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

libxml2-dev/focal,now 2.9.14+dfsg-0.1+ubuntu20.04.1+deb.sury.org+1 amd64 [installed] libxml2/focal,now 2.9.14+dfsg-0.1+ubuntu20.04.1+deb.sury.org+1 amd64 [installed,automatic]

I was able to fix some issues by looking at assets/scripts/compile output. Still unable to fix the following though

CMake Generate step failed. Build files cannot be regenerated correctly.

Thank you for the feedback, your input is greatly appreciated.

I have installed ubuntu 20.04 and upgraded python to 3.10 using these instructions and upgraded cmake to version 3.20 using these instructions. Note that the cmake instructions are missing a step sudo apt install libssl-dev

I have been able to re-create the error you are seeing regarding SDL.h. It looks like the version installed by ubuntu 20.04 is not compatible with cmake 3.20, which is unfortunate. You can get the thing to compile with a little effort editing the libavio/CMakeLists.txt file to look like this. Basically, what you are doing is commenting out the find_package(SDL2) routine and hard-coding the file locations. You might want to try the command find /usr/lib -name SDL2 to verify the locations just to be sure they are correct.

I think as a general rule, I wouldn't be able to support this Ubuntu version, so I don't think I would be making any changes to the repository other than to say that the minimum supported version for ubuntu is 22.04. Once again, thank you so much for the feedback and please let me know if you need any further help.

Best Regards,

Stephen
