问题
I am using macOS 10.15.2 Catalina and I followed the Installation Guide for macOS. I completely followed the Installation Guide and still I am unable to debug.
Anyone encountered the same? or know how to fix it?
Many thanks. Yasir

Adding more details below for @Rudi
When I try to install to install OMNet++ 6 pre 5 and do make, I am getting following error and it seems that OMNet++ 6 pre 5 is also not tested for macOS Catalina 10.15.

回答1:
Have you tried also OMNeT++ 6 pre 5? It contains an lldbmi wrapper executable that would use system provided lldb instead of gdb which may fix a lot of potential problems (and may cause other ones). But it would worth a try.
Even if you get gdb signed properly on macOS it will not support dynamic loading so it would be more or less useless (unless you build everything statically).
