libtool: Cheap tricks

1 15.5 Cheap tricks

1 Here are a few tricks that you can use to make maintainership easier:
1
1 * When people report bugs, ask them to use the '--config', '--debug',
1 or '--features' flags, if you think they will help you. These
1 flags are there to help you get information directly, rather than
1 having to trust second-hand observation.
1
1 * Rather than reconfiguring libtool every time I make a change to
1 'ltmain.in', I keep a permanent 'libtool' script in my 'PATH',
1 which sources 'ltmain.in' directly.
1
1 The following steps describe how to create such a script, where
1 '/home/src/libtool' is the directory containing the libtool source
1 tree, '/home/src/libtool/libtool' is a libtool script that has been
1 configured for your platform, and '~/bin' is a directory in your
1 'PATH':
1
1 trick$ cd ~/bin
1 trick$ sed 's%^\(macro_version=\).*$%\1@VERSION@%;
1 s%^\(macro_revision=\).*$%\1@package_revision@%;
1 /^# ltmain\.sh/q' /home/src/libtool/libtool > libtool
1 trick$ echo '. /home/src/libtool/ltmain.in' >> libtool
1 trick$ chmod +x libtool
1 trick$ libtool --version
1 ltmain.sh (GNU @PACKAGE@@TIMESTAMP@) @VERSION@

1 The output of the final 'libtool --version' command shows that the
1 'ltmain.in' script is being used directly. Now, modify '~/bin/libtool'
1 or '/home/src/libtool/ltmain.in' directly in order to test new changes
1 without having to rerun 'configure'.
