Hello list,
any idea why private variables from C++ source files are not included into
symbols list with -g3 and -ggdb compilation settings in gcc version 11.3.0
under Cygwin. Like that, roughly:
grep isInProgress *
<file_name>: bool isInProgress;
$nm -Cal <file_name_of_executable>|grep isInProgress
$
So, watchpoints obviously do not work. Why is it like this ?
Kind Regards
Ariel Burbaickij

I had a similar problem with -g3 -ggdb: macros were not recognised.
Using -g3 -gdwarf4 fixed that for me.
IIUC -ggdb is supposed to select the optimum debug format for gdb. It may be a
bug that it no longer does.
HTH,
Cheers ... Duncan.

Hello Duncan,
Interesting branch to take -- I have not checked it myself but there are
claims that DWARF-4 (has to be written this way too in options) is
Turing-Complete -- but no, still the same in terms of information available
-- which starts to look seriously strange.
Kind Regards
