QNX Momentics IDE User's Guide
- Working with QNX Momentics IDE
  QNX Momentics IDE provides a graphical environment for developing, running, debugging, and profiling applications.
- Developing Projects with the IDE
  To use the QNX Momentics IDE to write applications targeted for QNX OS systems, you must define projects, which are containers that store your source code, configuration files, and binary files.
- Debugging Applications
  The IDE allows you to debug a running application, a library used by the application, or a core file.
- Unit Testing
  The IDE lets you use commercial test frameworks to write unit tests and then execute them by launching a project. While running a test program, you can use the Code Coverage tool to determine how much of the code is exercised (covered) by your tests.
- Analyzing Memory Usage and Finding Memory Problems
  QNX Momentics IDE lets you run Memory Analysis and several Valgrind (pronounced val-grinned) tools to find memory problems such as leaks and corruption, and to measure memory usage of programs. It also provides the QNX System Information perspective so you can learn which processes are consuming memory or other resources excessively.
- Analyzing Performance
  QNX Momentics IDE works with the Application Profiler and Valgrind (pronounced val-grinned) Cachegrind tools, which measure the performance of programs running on QNX targets. It also offers the QNX System Information perspective for viewing performance-related metrics.
- Analyzing System Behavior
  Many IDE tools allow you to find errors and optimize applications, but to ensure that your embedded system behaves well, you need to use system-wide diagnostic tools. The QNX System Information and QNX System Profiler tools help you understand process and thread interaction on the target, reduce application and system startup times, and debug deadlock and improper CPU usage levels.
- Building QNX OS Images
  Using the IDE's QNX System Builder feature, you can generate OS images, which are bootable images that contain startup code, the QNX OS, your applications, and any data files used by your applications. The IDE supports image building by allowing you to transfer an image to a target board.
- Reference
  The reference topics provide information about QNX Momentics IDE features and workflows that isn't covered in the chapters related to developing projects or debugging, testing, and analyzing applications.
- JTAG: Debugging with Lauterbach TRACE32
  The Lauterbach TRACE32® In-Circuit Debugger (TRACE32-ICD) supports the JTAG onchip interface so you can perform hardware debugging of QNX OS systems through the QNX Momentics IDE.

QNX Tool SuiteIntegrated Development Environment User's GuideDeveloperSetup

This User's Guide describes version 8.0 of the Integrated Development Environment (IDE) that's part of the QNX Tool Suite. The guide introduces you to the QNX Momentics IDE by explaining the QNX development environment and how to build, run, and debug your QNX OS applications and systems. It then describes scenarios for analyzing memory usage and finding errors in applications.

This guide assumes the following:

On your host, you've installed the QNX Software Development Platform (SDP), which includes the QNX Tool Suite.
You're familiar with the System Architecture guide of QNX OS.
You can write code in C or C++.
You can edit makefiles and in particular, add compiling and linking options when needed.
You're comfortable using the Eclipse platform.
