GNU Compiler Collection (GCC) is an open-source, cross-platform compiler system developed by the GNU Project running on Linux operating system. The arm-none-eabi-gcc cross compiler is based on GCC, and supports the instruction sets of ARM CPUs, making it an ideal choice for GR55xx SoCs.

In software development, Make is a build automation tool that automatically compiles and links the project source files based on the makefiles. Makefiles specify the rules of compiling and linking multiple project source files with compilers, and enable users to call and to execute system commands.

This document introduces the approaches for building the development environment for GR55xx SoCs with GCC and makefiles in Ubuntu, a Linux distribution, and on Windows. The document also provides users with examples.

Before getting started, you can refer to the following documents.
