GNU Make hay còn gọi là gmake hoặc make, là một công cụ mặc định trên Linux được dùng trong quá trình compile thư viện hoặc một chương trình nào đó. Một bộ 3 công cụ và script sau được dùng trong qúa trình trên:
+ Make (GNU Make)
+ Makefile (Shell script)
+ GCC Compiler
Makefile chứa các thông tin và chỉ dẫn (các lời gọi lệnh GCC Compiler); Make sẽ đọc, phân tích Makefile để làm các công việc theo các hướng dẫn trong đó.
