Getting the Most Out of Eclipse CDT 3.0

Scaling the DOM

For standard build projects, determining build information is more difficult since in this case the CDT doesn't manage the build settings for the project. Thus, the project properties dialogs allow the developer to manually enter the include paths and macros. The CDT also provides a mechanism to automatically discover these settings; this mechanism will scan the build output, try to determine the build commands that are used, and extract the build information from there. CDT 3.1 introduces the option of importing a previously run build from which to extract the information. (See Figure 4)

To support multiple tool chains, both the standard and managed build systems support the setting of environment variables that are exported to the environment before running the build. Using this facility, the developer can change the PATH used to find compilers and linkers and set other environment variables that the build tools may require. (see Figure 5)

CDT Debug
The debug component of the CDT provides visualization of the debug session. A native debugger such as gdb handles the nuts and bolts of executing the application, setting breakpoints, and extracting variable values. Out-of-the-box, the CDT supports integration with gdb using gdb's MI text-based protocol. The CDT also provides an extensibility mechanism that lets other debuggers be integrated in the same way.

The CDT provides standard Eclipse visualizations for debug, including a list of threads, stack frames for currently paused threads, and variable values. CDT 3.1 introduces a new memory view from the Eclipse platform that supports a number of formats for memory values and enables the developer to browse more than one location at a time.

CDT 3.1 also introduces a new modules view (See figure 6) that shows the executable being debugged as well as the shared libraries and objects that the executable has loaded. The modules view can display any available symbol information, letting the developer set breakpoints on functions defined in the modules.

The CDT also provides a register view (see Figure 7) for C/C++ debugging. Version 3.1 extends this view by letting the developer organize registers into groups - especially useful for processors that have large numbers of registers.

Future Directions
With release 3.1, the CDT has reached a level of maturity that will ensure its widespread adoption by C and C++ developers. Nevertheless, the CDT team has planned some new features that will help the CDT become an even better IDE.

While the new ctags-based indexer can build an index for source navigation in dramatically less time, it suffers from less-than-perfect accuracy and doesn't capture references to identifiers. To address this problem and improve the performance of CDT's parser-based full indexer, the CDT team has developed a new strategy that allows the parser to make use of the results stored in the index. This way the parser can support most CDT features by parsing each file only once after the file changes. This approach will greatly improve the performance and scalability of large projects.

An interesting new Eclipse project is Photran, which is dedicated to building a Fortran IDE based on the CDT. To create the first version, however, the Photran team needed to clone the code in the CDT and then make changes to it. While some parts of the CDT, such as the managed build system, already offer multi-language support, the CDT team will add new extension mechanisms to make it easier for language developers to add new language support. This should allow the Photran team to build directly on the CDT and let them leverage the source navigation features of the CDT.

Joining the CDT Community
The CDT has a large and diverse community that contributes in a variety of ways. Committers, the people who have the power to change code, include members from QNX Software Systems, Intel, Texas Instruments, IBM, and Wind River. Other contributors contribute patches on a smaller scale, though these contributions are still critical to the success of the CDT. These contributors include HP, Siemens, and Symbian. A number of other contributors contribute by testing, submitting bug reports, and requesting enhancements.

In October 2005, QNX hosted a CDT Contributors Summit in Ottawa. Members of over 20 major organizations participated, representing the embedded, enterprise, and scientific/research segments of the C/C++ market.

The CDT is used in many places and by many people. Recently, we recorded 130,000 downloads of the CDT in a two-month span, including 50,000 downloads of CDT 3.1.1 in the two weeks following its release. These numbers represent a significant portion of the Eclipse community in general, proving again that the scope of Eclipse extends far beyond Java development.

The CDT community is always open to more contributions. For up-to-date information and instructions on how to contribute, visit http://wiki.eclipse.org, then click on "CDT Project" in the projects list. Contributors also meet on the [email protected] mailing list to discuss technical issues and make program decisions.

When shopping for a new data processing platform for IoT solutions, many development teams want to be able to test-drive options before making a choice. Yet when evaluating an IoT solution, it’s simply not feasible to do so at scale with physical devices. Building a sensor simulator is the next best choice; however, generating a realistic simulation at very high TPS with ease of configurability is a formidable challenge. When dealing with multiple application or transport protocols, you would be...
Smart cities have the potential to change our lives at so many levels for citizens: less pollution, reduced parking obstacles, better health, education and more energy savings. Real-time data streaming and the Internet of Things (IoT) possess the power to turn this vision into a reality.

We are given a desktop platform with Java 8 or Java 9 installed and seek to find a way to deploy high-performance Java applications that use Java 3D and/or Jogl without having to run an installer. We are subject to the constraint that the applications be signed and deployed so that they can be run in a trusted environment (i.e., outside of the sandbox). Further, we seek to do this in a way that does not depend on bundling a JRE with our applications, as this makes downloads and installations rat...

In this strange new world where more and more power is drawn from business technology, companies are effectively straddling two paths on the road to innovation and transformation into digital enterprises. The first path is the heritage trail – with “legacy” technology forming the background. Here, extant technologies are transformed by core IT teams to provide more API-driven approaches. Legacy systems can restrict companies that are transitioning into digital enterprises. To truly become a lead...
Digital Transformation (DX) is not a "one-size-fits all" strategy. Each organization needs to develop its own unique, long-term DX plan.
