Re: [Anjuta-list] debugging problem

[Alexander F Borro <alex borro blueyonder co uk>]

On HPUX I usually do this, I don;t know if that works with LInux as it
may be implementation specific (gdb info says)

`set follow-fork-mode MODE'
      Set the debugger response to a program call of `fork' or `vfork'.
      A call to `fork' or `vfork' creates a new process.  The MODE can
      be:
 
     `parent'
           The original process is debugged after a fork.  The child
           process runs unimpeded.  This is the default.
 
     `child'
           The new process is debugged after a fork.  The parent process
           runs unimpeded.
 
     `ask'
           The debugger will ask for one of the above choices.
 
 `show follow-fork-mode'
      Display the current debugger response to a `fork' or `vfork' call

The only othere way is to attach to it by putting a sleep in there to
give you enough time. I expect (I guess) you are getting the error
message bacause the child had already terminated before you managed to
attach to it.
