Norman / Vimba X Dev Team,

Thank you for your help in trouble shooting this problem with me. I have created a YouTube video showing an example of Vimba X Startup() working and then not working after linking a library.

The source code and CMake scripts for Ubuntu 22.04 as well as the video linked above is available on my local server at.

http://www.nykl.net/vimba   (Notice there is *no* S on http )


If needed, the exact step-by-step apt-get install commands that I used to install the development environment for the Ubuntu 22.04 shown in the video is available at:

The bottom of the forum post discussing this problem shows the same output as the YouTube / Video linked above. The forum link is at https://forum.alliedvision.com/t/application-note-cross-compiling-vimba-source-code-to-arm/20/12


I used g++ 13.1 to compile all of my code samples (I'm using C++23) and have the debug symbols as well as the memory sanitzer -fsanitize turned on (see the CMakeLists.txt for the compiler flags).

I'd be more than willing to try using a static version of your VimbaCPP/VimbaC libraries in my application. I can also drop is a quick updated .so from the dev team. We are supposed to be shipping (actually flying this system within a few weeks) and this problem has eaten up a good week of my time and left me scratching my head!

Given what I know, my biggest hint so far has been the ADDRESS SANITIZER reporting. Please let me know if you need any additional information. Also,
