In software development, GNU Automake is a programming tool to automate parts of the compilation process. It eases usual compilation problems. For example, it points to needed dependencies.

It automatically generates one or more Makefile.in from files called Makefile.am. Each Makefile.am contains, among other things, useful variable definitions for the compiled software, such as compiler and linker flags, dependencies and their versions, etc. The generated "Makefile.in"s are portable and compliant with the Makefile conventions in the GNU Coding Standards, and may be used by configure scripts to generate a working Makefile.

The Free Software Foundation maintains automake as one of the GNU programs, and as part of the GNU build system. It is used to build several GNU applications and libraries, such as GTK, as well as non-GNU software such as XCircuit.
