my 6.22 install outside of conda still works so I’ve reverted to that while I wait for xcode to settle down. But I’d be interested if other people have seen this problem and how they dealt with it. This is unfortunately in a complicated cmake environment and a simple compile with root doesn’t cause the issue so I’m still working on a simpler reproduction as a test case.

A Reddit user has said that the latest macOS update has removed the need to reinstall. (Source 1, 2) Now, it seems that this issue might have been addressed in the latest macOS Big Sur 11.3.1 update. Of course, Xcode’s console panel doesn’t support that either (-: To get around this, run your program with its standard I/O channels connect to a Terminal window. Basically, users have to run the Xcode-select install command to install the command line tools after every macOS Big Sur incremental update. You can generate that in Terminal using ^T. The traditional BSD approach for this is to use SIGINFO rather than SIGINT. I have a bunch of hints and tips on this front.
So, to be clear, you’re running a program in Xcode and thus using Xcode’s built-in LLDB to debug it? Right? As opposed to running the program using the lldb command line tool?Īssuming that, you’re correct that Xcode’s console panel does not map ^C to SIGINT.
