What's new?#

• Eclipse 3.3 platform
• CDT 4.0
• A managed build integration for the QNX tool chain
• The QNX System Information enhancements with malloc information view that include various charts to help you observe changes in memory usage (allocations and deallocations). Because it is important for you to know when and where memory is being consumed within an application, the Memory Analysis Tooling feature includes several views that use the trace information from the Memory Analysis session to help extract and visually display this information (to determine memory usage; allocation and deallocation metrics). The IDE includes the these new tabs to help you observe changes in memory over time: Outstanding allocations, Allocation deltas, Deallocation deltas, and Outstanding allocation deltas. To access these tabs, select Window->Show View-->Other from the menu in the IDE, and then select QNX System Information-->Malloc Information, and click OK.
  • Note: For you to begin to view data on your graphs, you need to set logging for the target, and you need to select an initial process from the Target Navigator view.
• The Memory Analysis Tool lets you import and export trace data from a Memory Analysis session view. With the Memory Analysis Tool, you can:
  • Export session information in CSV or XML format. In the IDE, you can export your trace data session information from a Memory Analysis session view. When exporting memory analysis information, the IDE lets you export the event-specific results in .csv format, and the other session trace data in .xml format. Later, you can import the event-specific results into a spreadsheet, or you can choose to import the other session trace data into a Memory Analysis session view to review the results. To export, click File-->Export from the menu, and then select QNX-->Memory Analysis Data.
  • Import memory analysis event data or XML data. In the IDE, you can import trace data session information from a Memory Analysis session view. When importing memory analysis session information, the IDE lets you import the event-specific results for libmalloc events in .csv format, and the other session trace data in .xml format. To import, click File-->Import from the menu, and then select QNX-->Memory Analysis Data.

Installation Instructions#

To install IDE Tau Alpha I:

• 1. Download and install QNX Momentics 6.3.2.
• 2. Download IDE Tau Alpha I from the Project Download area.
• 3. Save the ".zip" file you downloaded to a temporary directory. Use your favorite unzip program (such as "Winzip" on Windows, or using the "unzip" command on Linux) to extract the zip file.
• 4. Extract the zip file content. The extraction process creates an "eclipse" directory.
• 5. For Linux:
  • a.) Ensure that the "$QNX_HOST/usr/bin" appears at the beginning of the $PATH environment variable. To verify where it appears in the $PATH variable, use the following command in a shell:
    • echo $PATH
  • b.) Set the "LD_LIBRARY_PATH" by issuing this command:
    • export LD_LIBRARY_PATH=$QNX_HOST/usr/bin:$LD_LIBRARY_PATH
  • c.) To launch the IDE, run "eclipse/qde".
• 6. For Windows:
  • a.) Ensure that "%QNX_HOST%\usr\bin" is included in the %PATH% environment variable. To verify where it appears in the $PATH variable, use the following command in a Windows command prompt:
    • set %PATH%
  • b.) To launch the IDE, run "eclipse\qde.exe".

After You Install#

After you install IDE Tau Alpha I, the first time you start the IDE on Windows, the Workspace Launcher dialog prompts you for a location to store your workspace. By default, the IDE offers to put your workspace in a sub-directory called "ide-tau-workspace". To store your workspace in another location, click "Browse" and select a directory for your workspace. To continue loading the IDE, click "OK".

After you choose a workspace location, the IDE displays a Welcome window with several options that help introduce you to the QNX Momentics IDE:

• Overview Icon: Provides links to overviews within the IDE, including the Documentation Roadmap, Team Support (an important topic if you use CVS), Workbench Basics, and the C/C++ Online Documentation.
• Tutorials Icon: Provides links to the tutorials for building your first QNX applications.
• Samples Icon: Provides links to samples to help you explore QNX Momentics by installing various prefabricated samples.
• What's New Icon: Provides links to documents describing the new features in this release, and information about migrating from a previous release.
• Workbench Icon: Opens the workbench window and minimizes the Welcome page.

Once you open the Workbench, you'll find an extensive set of online documentation in HTML format. In the IDE, choose Help-->Help Contents.
