Debugging Problem with Gnatbench under Eclipse

[Fritz von Braun <fritzvonbraun@gmail.com>]

Hello,

I am new to Ada, Eclipse and newsgroups so I may just make some dumb mistake here, but I cant figure out how to correct this, I searched the web over and over but could not find any help with this problem.

I installed the latest Eclipse 32 bit version, the CDT tools and Gnatbench just as described. I created a small Hello World program which compiles and runs just fine. But when I try to start it under the Eclipse GDB debugger I get the following error:

Error in final launch sequence
Failed to execute MI command:
-data-evaluate-expression "sizeof (void*)"
Error message from debugger back end:
No definition of "sizeof" in current context.
No definition of "sizeof" in current context.

Debugging a C++ program in Eclipse works. I tried all sorts of combination with the Debugging configurations offered when starting Ada debugging but they all create the same error.

Any help would be appreciated

Thanks
