debugging with gdb

debugging with gdb

[antonio]

I'totally new in ada95 and i try to debug a simple program written in
ada95 (i.e hello world).I have compiled with gnatmake(-g option)and i
get an executable that   i ran into gdb.It works but i can't see the
original source using the gdb command 'list' and (obviously) i can't
put any break point where i want like i usually do when i work in C.
why?
tank you in advance.

What Version of GNAT and what version of gdb are you using?

You could try downloading GVD - a GUI front end to gdb. This may
make life little easier. It's now integrated into GPS an IDE for GNAT.

Perhaps GDB is looking in the wrong directory for your source files.
You can specify where your source files are using the `dir' command
(try `help dir', too).  I could help better if you gave us the exact
commands you used to compile your program and to run GDB.  Also, does
GDB output any error message when you say `list'?

You can debug Ada programs using GDB, but GDB by default does not
understand Ada syntax, and you won't be able to set breakpoints on
exceptions.  For these additional features, you need an Ada-aware GDB
available from http://libre.act-europe.fr/GDB.  If you are a Debian
user, you can also apt-get install gnat-gdb to get it (in unstable).

Others have pointed you to GVD and GPS.  Both are front-ends to GDB,
so you'll need GDB to work for you anyway.  Emacs also has such a
front-end.

You are most likely using a gdb version that is not Ada-aware. PLease
state: OS you use, version of gdb and gnat.
