Eigen matrices are not working, python crashes in gdb (solution is a one liner) #157
Description
Environment
- OID version (commit or tag): v1.9.20
- OS and Version: ubuntu 20.4
- Which debugger [gdb and/or lldb] and respective versions: gdb 9.2
- Python version: 3.8.10
Describe the bug
The installation was very well documented and there were no problems.
I tried this tool out with a very small C++ file with small Eigen matrices. And although the variables are detected in the gui of OID correctly, they can not be plotted, because python crashed in the background.
To Reproduce
Steps to reproduce the behavior:
- debug a cpp file with eigen matrices with gdb
- Select the variable in the gui
Expected behavior
The matrix entries should be shown as an image.
Actual behavior
No image is shown, only a traceback in gdb is shown.
