The ICAT Debugger (hereafter referred to in this chapter as the debugger) is a source-level debugger which uses OS/2 Warp 3.0, OS/2 Warp Connect, or OS/2 Warp Version 4 to assist in detecting and diagnosing errors in an OS/2 Warp Server for SMP system. It provides a graphical user interface and debugs PM and non-PM (single- or multi-threaded) applications as well as device drivers and other system-level binaries.
This debugger has been designed to debug remotely an OS/2 Warp Server for SMP system. The Kernel Debugger (KDB) runs on a victim OS/2 Warp Server for SMP machine and replies to debug service requests that are sent from the debugger while running on an Intel-based OS/2 Warp 3.0, OS/2 Warp Connect, or OS/2 Warp Version 4 machine. The supported communication mode between machines is serial.
Supported debug file formats include HLL (which is IBM VisualAge C++ (VACPP)) and CodeView (CV).
