17.5 How gawk Finds Extensions
Compiled extensions have to be installed in a directory where gawk
can find them. If gawk
is configured and built in the default fashion, the directory in which to find extensions is /usr/local/lib/gawk
. You can also specify a search path with a list of directories to search for compiled extensions. See section The AWKLIBPATH Environment Variable for more information.
