Debugger crashes with Apple Silicon code
« on: July 05, 2023, 03:52:47 pm »
When trying to start a file compiled for Apple Silicon processors the debugger enters an error state. The program can be executed but without a debugger only.

This issue may have been discussed previously, but I am not sure if this is the same error and, obviously, no solution is available.

end;

I assume you are using "lldb + fpdebug"?

What does the menu: View > IDE internals > Debug output show? (Note: First open the window, then try to run the app in the debugger)


Is it possible to load the app in lldb, and run it under lldb?
- See above output for lldb commands needed. / Do any of them need change?
- What does lldb report

Well, I can run my program from lldb.

The debug output from Lazarus is very long:

I don't think that they are too important. At least the program starts.

Could the line "the platform is not currently connected" in the Lazarus output be the key?

Quite possible.
Or "r" vs "process launch -n"
Also a diff in your test, the name of the app. Under the IDE it ended in ".app"

The problem is I don't develop on Mac, so I can't test it.
I know some people are (or at least were) able to start M1 apps. But I can't tell what changed.

Re: Debugger crashes with Apple Silicon code

I got this error, after I had some application updates (notably X-Code) and an OS update (this is on Ventura, by the way). It confused me as it was working before. When I then tried to install with FPCUpDeluxe I got the message that I hadn't accepted the licence agreement with X-Code (obviously, the updated version)...so maybe yours is the same issue?

sudo xcodebuild -license
