The GNU Compiler Collection (GCC) is a set of compilers produced for various programming languages by the GNU Project. GCC is a key component of the GNU toolchain. Originally named as "GNU C Compiler" the GCC has been extended to compile C++. Distributed by the Free Software Foundation (FSF) under the terms of the GNU General Public License (GNU GPL) and the GNU Lesser General Public License (GNU LGPL), GCC is free software.

Hitex has many years of experience developing and working with the GNU compiler and accompanied many successful projects based on it. All ARM and Cortex development tools from Hitex are delivered with a GNU compiler edition built and tested by Hitex.
