PetscAttachDebugger#
Attaches the debugger to the running process.
Synopsis#
#include "petscsys.h"
PetscErrorCode PetscAttachDebugger(void)
Not Collective
Options Database Keys#
-start_in_debugger [noxterm,lldb or gdb] [- display name] [-debugger_ranks m,n] - set debugger debug_terminal xterm or Terminal (for Apple)
-on_error_attach_debugger [noxterm,dbx,xxgdb,xdb,xldb,gdb] [- display name] - Activates debugger attachment
-stop_for_debugger - print a message on how to attach the process with a debugger and then wait for the user to attach
Note#
If you get the message “ stdin is not a tty, hence unable to attach debugger, see PetscAttachDebugger()”, this means the application
is likely running in a batch system and you do not have terminal access to the process. You can try
running with -start_in_debugger without the noxterm argument or -stop_for_debugger
Developer Note#
Since this can be called by the error handler, should it be calling SETERRQ() and PetscCall()?
