autoreconf

Regenerate all autotools files

$ autoreconf

$ autoreconf --install

$ autoreconf --force --install

$ autoreconf --install --verbose

autoreconf [-f] [-i] [-v] [options]

autoreconf runs autoconf, autoheader, automake, and related tools in the correct order. It's the recommended way to regenerate configure scripts and related files in autotools projects.
The tool automatically determines which programs to run based on project configuration.

-i, --install

Add missing auxiliary files

Force regeneration even if files are current

Verbose output

Use symlinks instead of copies for auxiliary files

Warning level

Don't recurse into subdirectories

Typical usage when building from git:

$ autoreconf --install
./configure
make

Requires autoconf, automake, and related tools installed. Can be slow on large projects. Modern alternatives (CMake, Meson) are often easier.

autoreconf was added to autoconf to simplify the complex process of regenerating autotools files in the correct order.
