[petsc-users] debugger does not work on my machine

[Wen Jiang]

Hi all,

I was trying to use the gdb debugger by

mpiexec -n 2 ./myprogram -start_in_debugger

I got the error:

*******************************************************************************************
[1]PETSC ERROR: PETSC: Attaching gdb to ./myprogram of pid 60344 on display
knossos:0.0 on machine knossos
[0]PETSC ERROR: PETSC: Attaching gdb to ./myprogram of pid 60343 on display

Unable to start debugger in xterm: No such file or directory
Unable to start debugger in xterm: No such file or directory
*******************************************************************************************

I tried mpiexec -n 2 ./myprogram -start_in_debugger noxterm

I got the information, some of them are

*******************************************************************************************

( Does this mean I need to install those libraries? I also tried to install
as root, but it said that 'Could not find debuginfo pkg for dependency
package libxcb-1.5.1-el6.x86_64'.

My system is scientific linux and it use GNOME 2.28.2. I am wondering how to
fix this problem.

Thanks,
Wen
