GNU Libtool - The GNU Portable Library Tool

GNU Libtool is a generic library support script that hides the complexity of using shared libraries behind a consistent, portable interface.

To use Libtool, add the new generic library building commands to your Makefile,, or See the documentation for details.


Source releases

They are available from the main GNU server (HTTPSHTTPFTP) and its mirrors; please use a mirror if possible.

Latest stable release:  libtool-2.4.7.tar.gz

Development sources

They are available via Git. Use the following command to check them out:

$ git clone git://

Once you have the tree checked out, you can keep it up to date by using "git pull". Please see the Libtool project page for more information.


The GNU Libtool manual is available in various formats. You may also find information about GNU Libtool by running "info libtool" on your system.

Mailing Lists

Libtool has three mailing lists: Libtool previously used the list to track bug reports; we ask that you now use Savannah's Tech Support Manager instead. See Submitting bug reports for details.


To subscribe to any GNU mailing lists, please send an empty mail with a Subject: header line of just “subscribe” to the relevant -request list. For example, to subscribe yourself to the GNU announcement list, you would send mail to <> with no body and a Subject: header line of just “subscribe”. Or you can use the mailing list web interface.
