If you are using macOS 10.15 Catalina and the recent CLion release 2019.2.3 (or any CLion version earlier than 2019.2.2), please update to get the LLDB working.
macOS Catalina was finally released a few days ago. We started testing and fixing some issues there well in advance, and CLion 2019.2.2 was released a month ago with a fix for LLDB on Catalina.
Unfortunately, in CLion 2019.2.3 the debugger on Catalina was broken. After the official macOS release, our users have faced an issue when launching the debugger (CPP-17613). We are really sorry about this, and we’re now releasing a new bug-fix update 2019.2.4 with the proper fix included.
We’ve also investigated the issue internally to prevent similar problems in the future.
CLion 2019.3 EAP is not affected and has LLDB working on Catalina.
Please note that some possible warnings (CPP-17268) are still present but don’t seem to prevent debugging. Also, another update CLion 2019.2.5 with more fixes from the IntelliJ Platform, which in particular targets macOS 10.15 Catalina users, will be released in a few weeks. Stay tuned!
