C and C++ Developer Tools
GCC
The GNU Compiler Collection includes front ends for C, C++, Objective-C, Fortran, Java, and Ada, as well as libraries for these languages (libstdc++, libgcj,...).
We strive to provide regular, high quality releases, which we want to work well on a variety of native and cross targets (including GNU/Linux), and encourage everyone to contribute changes and help testing GCC. Our sources are readily and freely available via SVN and weekly snapshots.
Major decisions about GCC are made by the steering committee, guided by the mission statement.
Eclipse
Eclipse is an open source community whose projects are focused on building an open development platform comprised of extensible frameworks, tools and runtimes for building, deploying and managing software across the lifecycle. A large and vibrant ecosystem of major technology vendors, innovative start-ups, universities, research institutions and individuals extend, complement and support the Eclipse platform.
KDevelop
The KDevelop-Project was founded in 1998 to build up an easy to use IDE (Integrated Development Environment) for KDE. Since then, the KDevelop IDE is publicly available under the GPL and supports many programming languages.
