QNX® Momentics® Development Suite Eclipse and CDT Introduction

What is Eclipse? è Eclipse is - a vast open source community ► 17 Strategic Members, 79 Add-in Provider Members, many independent contributors ► Widely adopted § 50 million downloads since 2001 (as of 2005) § 1 million downloads of Callisto (3. 2) 40 days after release è Eclipse is - A collection of open source projects ► è “providing an extensible development platform and application frameworks for building software” (www. eclipse. org) Eclipse is – A platform ► Core Runtime, GUI, and IDE features ► An SDK for building plug-ins for the Platform All content copyright of QNX Software Systems Co. 4

History of Eclipse è Originated at IBM in 2000 è Foundation for Web. Sphere Studio Application Developer® ► è IBM had vision to see the value of open source technologies ► è Good experience with Apache and Linux Formed Eclipse Consortium November 2001 ► è Intended to compete with Microsoft® Visual Studio® in enterprise Involved both partners and competitors Gave technology and leadership to Eclipse Foundation ► February 2004 ► Combat the perception that IBM still owned Eclipse All content copyright of QNX Software Systems Co. 5

What is the CDT? è One of the major Eclipse tools projects è A set of plug-ins that support C and C++ development ► Extend many of the Eclipse Platform extension points è Support Edit/Build/Debug cycle è Out-of-the-box support for gnu tools for host development ► è Platform for integrating other toolchains ► è gcc, g++, gdb, binutils, etc. Compilers, debuggers, build systems, … Platform for adding other C/C++ tooling ► Embedded tools to support unique needs of embedded systems All content copyright of QNX Software Systems Co. 6

History of the CDT è Project launched July 2002 ► è At QNX headquarters in Ottawa, Canada Initially populated with contribution from QNX Additional participation from Rational, Monta. Vista, and Red Hat ► Again, both partners and competitors ► è CDT releases regularly with latest being 3. 1. 1 in Sept 2006 è Contributions from: ► ► ► QNX - initial contribution, core and debug Rational/IBM - parser technologies Intel and Texas Instruments - makefile generation Wind River - refactoring Others coming… All content copyright of QNX Software Systems Co. 7

QNX is Committed to Eclipse and CDT QNX is a founding member of the Eclipse Consortium è QNX contributed the original implementation of the CDT to Eclipse and has guided the evolution of the CDT project, from its humble beginnings of 80, 000 LOC to over 700, 000 LOC today è The CDT is the second most popular project on Eclipse, following only the Eclipse platform itself è è Simultaneously leverage open standards like Eclipse while taking advantage of high value-add functionality and world-class innovation through standardized extension points Designed for embedded: cross-compiler support, easy debugging, extended for target management ► Seamless support for third-party plug-in tools and optimizing compiler technology ► High developer productivity: no additional learning curve, high performance IDE, reliable platform, scalable to large projects ► All content copyright of QNX Software Systems Co. 8

Who creates products that include the CDT? There are over 17 commercially available products based on Eclipse and CDT All content copyright of QNX Software Systems Co. 9
