Howto Use OpenFOAM with NetBeans
The NetBeans IDE is a free, open-source Integrated Development Environment that runs on several platforms including Windows, Linux, Solaris, and MacOS. It is easy to install and use straight out of the box.
The C/C++ development pack (available as a separate download) adds project types for C and C++ NetBeans Projects and includes appropriate C/C++ templates. NetBeans supports C/C++ applications with dynamic and static libraries, and projects with existing code. It also includes an advanced source-code editor which features code-completion, smart-indenting and syntax-highlighting capabilities. It readily integrates with an existing compiler installation (like gcc), and provides an interactive debugging environment (using gdb as a backend).
