The GNU build system, also known as the Autotools, is a suite of programming tools designed to assist in making source-code packages portable to many Unix-like systems.
It can be difficult to make a software program portable: the C compiler differs from system to system; certain library functions are missing on some systems; header files may have different names. One way to handle this is write conditional code, with code blocks selected by means of preprocessor directives (#ifdef); but because of the wide variety of build environments this approach quickly becomes unmanageable. Autotools is designed to address this problem more manageably.
Autotools is part of the GNU toolchain and is widely used in many free-software and open-source packages. Its component tools are free-software-licensed under the GNU General Public License with special license exceptions permitting its use with proprietary software.

Famous quotes containing the words build and/or system:
“You sold Marmaros to the Russians. Scurried away in the night and left us to die. Is it to be wondered at that you should choose this place to build your house? The masterpiece of construction, built upon the masterpiece of destruction, the masterpiece of murder. The murderer of ten thousand men returns to the place of his crime.”
—Peter Ruric, and Edgar G. Ulmer. Edgar G. Ulmer. Dr. Vitus Werdegast (Bela Lugosi)
“When the finishing stroke was put to his work, it suddenly expanded before the eyes of the astonished artist into the fairest of all the creations of Brahma. He had made a new system in making a staff, a world with full and fair proportions; in which, though the old cities and dynasties had passed away, fairer and more glorious ones had taken their places.”
—Henry David Thoreau (1817–1862)
