If such a file is lacking in the current directory, the appropriate directories are searched for it. If <samp>foo.c</samp> exists (or is mentioned in the makefile) in any of the directories, the implicit rule for C compilation is applied. </p> <p>The recipes of implicit rules normally use automatic variables as a matter of necessity; consequently they will use the file names found by directory search with no extra effort. </p><div class="_attribution"> + <p class="_attribution-p"> + Copyright © 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022 Free Software Foundation, Inc. <br>Licensed under the GNU Free Documentation License.<br> + <a href="https://www.gnu.org/software/make/manual/html_node/Implicit_002fSearch.html" class="_attribution-link">https://www.gnu.org/software/make/manual/html_node/Implicit_002fSearch.html</a> + </p> +</div> |
