Title: Debugger errors; How to fix it
Post by: AL on October 18, 2022, 04:44:40 pm

I am using lazdebuggerlldb  (lldb with fpdebug) in MacOs 12 Monterey
 
When I use DWARF 3 I get these errors and cannot run the program.
Any idea how to solve this?
Thank you

Good question. This could be a limitation in lldb, but also something that FPC gets wrong.

You can try to use "dwarf with sets" instead.

And if that does not work, add the custom option  --godwarfcpp  to the compiler opts. Though, it may depend on the fpc version if that does any good.

Is your FPC 3.3.1 recent? That is newer than the 10th Oct ?

There may be a bug in FPC that was introduced around that date

Yes installed Oct 18 !
Should I install an earlier version?

In the meantime it has been fixed. So you can update to the latest revision on the main branch.
