CodeLite is a free, open source, cross platform IDE for the C/C++ programming languages using the wxWidgets toolkit. To comply with CodeLite's open source spirit, the program itself is compiled and debugged using only free tools (MinGW and GDB) for Mac OS X, Windows, Linux and FreeBSD, though CodeLite can execute any 3rd party compiler or tool that has a command line interface.
CodeLite features project management (workspace / projects), code completion, code refactoring, source browsing, syntax highlight (see CodeLite Features page), Subversion integration, cscope integration, UnitTest++ integration, an interactive debugger built over gdb and a source code editor (based on Scintilla).
CodeLite is distributed under the GNU General Public License v2 or Later. It is being developed and debugged using itself as the development platform with daily updates available through Subversion.
