C. Information for developers

Gmsh is written in C++, the scripting language is parsed using Lex and Yacc (actually, Flex and Bison), and the GUI relies on OpenGL for the 3D graphics and FLTK (http://www.fltk.org) for the widget set. Gmsh's build system is based on CMake (http://www.cmake.org). Practical notes on how to compile Gmsh's source code are included in the distribution. See Frequently asked questions, for more information.
