RHIDE 1.3, GNAT (for DOS) and GDB - problem with watches

RHIDE 1.3, GNAT (for DOS) and GDB - problem with watches

[Matthew Kennedy]

Hello,

I'm having trouble debugging my Ada code under the RHIDE environment. I
am using an Ada 'aware' version of GDB and the Ada compiler is DOS GNAT.

The problem is that the IDE doesn't seem to recognise any Ada variable
names when I set watches - instead I get 'variable_x: Not Available'
even though the variable is in the current scope. Stepping though the
code, non-conditional breakpoints and 'run to cursor' work as expected.

Maybe there's some sort of pre/suffix for variable names that will get
me around this problem?

Thanks,
Matt.

An here is one of the problems. If the ADA maintainer would send the
gdb patches to the gdb maintainer (or when they have sent then if they
would accepted) RHIDE's builting gdb would have also the ADA debugging
patches. At least RHIDE 1.3c uses the latest GDB snapshot which is from
17. August 1997 and I checked it and there seems nothing related to
ADA.

In my opinion you can solve this by reading the ADA docs (I took a short
look at them and found it) to get infomation, how the ADA compiler
mangles
the variable names and you have to use this technique also for accessing
the variable.

This is documented in the ADA-docs.
