Compute Canada    The GNU debugger (gdb) is a standard tool for
debugging C and (to a lesser extent) Pascal code. It is largely
line-based and uses a standard set of commands, such as "print",
"stop at" or "stop in". The main reason for its installation on
the SunFire cluster is its use in combination with the Gnu
Pascal compiler gpc. This debugger is public domain and very
portable. Note that for Fortran and C/C++ programs, the use of
Oracle Solaris Studio is recommended.
