No keyboard input when running a C++ program in Xcode

Solved - to some extent.

I changed the Product Name in the Xcode Build Settings to 'Terminal' (see below).

Then when I ran the program from Xcode, I was prompted to give permission to the Terminal, which I did (see below).

It then worked. At least until I made any changes to the C++ program, at which point it stopped working. I then had to delete the Terminal permission and redo it again to get it working.

But oddly, if I returned the C++ program changes I had made, back to what they were originally, it worked straight away without having to do the permission again.

So anyway, this is not really a fix if I have to redo the permission every time I make a change to the C++ program. But hopefully what I've posted here, might help someone find a permanent solution to this problem.

Thanks for your help - it pointed me in the right direction.

Thanks. But I forgot to mention that I have already given authority for the keyboard to access the program in the 'Privacy and Security' preferences. But it still didn't work.

I just added the Terminal app and Xcode to the permissions. Then logged off and on again. But still no luck.

Thanks for your response, but I’m not sure what you mean by, ‘the hash the program generates’. Could you explain some more, and suggest a fix? I’m not an experienced programmer.

Regards.
