How to debug a C++ code

Hi,

I recently has a C++ code which only run on Fedora Platform.

I wanted to run debugging on these code as I came across some unexplainable
scenario output.

Can anyone suggest how could I use any debugger? I tried to use GNU GDB but then the code I am dealing now are involving multiple files background. So, I am not too sure how to debug in this matter.

I also thought of porting to Visual C++, but I am not so sure how to.

Please advise. Thanks..
Rgrds,
Jason

NAME
pmdbg - translate Performance Co-Pilot debug control flags SYNOPSIS
pmdbg code ... pmdbg -l DESCRIPTION
The components of the Performance Co-Pilot (PCP) use a global vector of bit-fields to control diagnostic and debug output. pmdbg with a -l argument prints out the mnemonic and decimal values of all the bit-fields in the debug control vector. In the alternative usage, the code arguments are values for the debug vector, and the bit-fields that are enabled by each of these values is listed. Each code may be an integer, a hexadecimal value or a hexadecimal value prefixed by either ``0x'' or ``0X''. Most applications using the facilities of the PCP support a -DN command-line syntax to enable debug control. pmdbg is designed to help choose an appropriate value for N. PCP ENVIRONMENT
Environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP. On each installation, the file /etc/pcp.conf contains the local values for these variables. The $PCP_CONF variable may be used to specify an alternative configura- tion file, as described in pcp.conf(5). SEE ALSO
