If multiple <code>ar</code> commands run at the same time on the same archive file, they will not know about each other and can corrupt the file. </p> <p>Possibly a future version of <code>make</code> will provide a mechanism to circumvent this problem by serializing all recipes that operate on the same archive file. But for the time being, you must either write your makefiles to avoid this problem in some other way, or not use <code>-j</code>. </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/Archive-Pitfalls.html" class="_attribution-link">https://www.gnu.org/software/make/manual/html_node/Archive-Pitfalls.html</a> + </p> +</div> |
