GDB macros

[Luca Germano]

Thanks for the help.
I try to use the rtems_classic_tasks macro but gdb give me the following 
reply

=====================================================================
Attempt to extract a component of a value that is not a structure.
# | Name |    ID    | Pri |  Ticks   | State
---+------+----------+-----+----------+------------------------------

How can I solve this problem?

Best regards
