GDB with Ada doesn't print variables neither works with GPS

["mike tiberium" <mike.tiberium@gmail.com>]

Hi,

It seems I'm unable to print variables properly in GDB when debugging
an Ada application. This is the best I can get:

(gdb) p /c Hello_String.all
$1 = (72 'H', 101 'e', 108 'l', 108 'l', 111 'o')

Any way I can solve this? =/

I used to be able to debug an Ada application using GNAT-GPS but after
some upgrades (kernel? libc?) things stopped working. Fortunately I
can still debug using GPS on the command line, but without an IDE it's
very hard due to Ada's complicator factor =[


Using GNAT-GPS:
file /path/to/app/hello
Using host libthread_db library "/lib/i686/cmov/libthread_db.so.1".
(gdb) break hello.adb:72
Breakpoint 1 at 0x809a450: file /path/to/app/sources/hello.adb, line 72.
(gdb) start -i data.txt
Breakpoint 2 at 0x809a050: file /path/to/app/sources/hello.adb, line 46.
/dev/ptypd: No such file or directory.

Program exited with code 01.
You can't do that without a process to debug.
(gdb) run -i data.txt
/dev/ptypd: No such file or directory.

Program exited with code 01.
You can't do that without a process to debug.
(gdb)

When I try to create the device, this is what I get:

Any idea on how to fix this?
