BornAgain GUI shows a blank window upon start

Under Ubuntu 24.04 LTS and Debian 12, BornAgain GUI (built based on commit 138efbd4) starts but displays a blank window.

• Error messages under Debian 12:

The problem can be reproduced under a clean Ubuntu 24.04 VM.

Further investigation via glxinfo (from mesa-utils package) yields:

$ glxinfo

The libraries iris_dri.so, swrast_dri.so and zink_dri.so are provided by libgl1-mesa-dri (try dpkg -L libgl1-mesa-dri). They are placed in /usr/lib/x86_64-linux-gnu/dri/ directory (try find /usr/ -iname "*_dri.so").

The problem seems to be related to the required GLIBCXX version (`GLIBCXX_3.4.30').

1. Check the table of versions of libstdc++ to see if GLIBCXX_3.4.30 is included:

strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX_3.4.30

2. Check the table of versions of libstdc++ of the conda environment to see if GLIBCXX_3.4.30 is included:

strings /path-to-conda/envs/my-env-name/lib/libstdc++.so.6 | grep GLIBCXX_3.4.30

If step 2 reveals that GLIBCXX_3.4.30 is not included in the version table of the libstdc++ of the conda environment, then rename the libstdc++ of the conda environment:

mv /path-to-conda/envs/my-env-name/lib/libstdc++.so.6 /path-to-conda/envs/my-env-name/lib/libstdc++.so.6.old

so that libstdc++ of the system would be used.

Execute BornAgain GUI to see if the issue is resolved.
