GNU Libtool 2.2.6 *RE*Released

Item posted by Gary V. Vaughan <gary> on Mon 08 Sep 2008 06:31:40 AM UTC.

I'm embarrassed to announce the release of GNU Libtool 2.2.6a.

This release is identical to yesterday's 2.2.6 release, except that I've calculated the libltdl version number correctly.  I was
overzealous about the library interface changes, and released 2.2.6 to build as it's soname (making it incompatible with earlier releases from the 2.2 branch using

My theory was that we had removed some of the argz access points that were accidentally exported on non-GNU/Linux machines, that strictly would require a new soname.  Since 2.2 is a maintenance branch, and since the removed access points were not documented and should not have been visible in any case, I've pulled the 2.2.6 release and tarballs from, and replaced them with equivalent files named with `2.2.6a'.  The mirrors should catch up shortly.

When built and installed, the 2.2.6a libtool releases will still be called 2.2.6 in the install tree, and are identical to yesterdays release in every way, with the exception of using the correct soname for libltdl, so that backwards compatibility with earlier stable 2.2 releases is not broken.  To avoid confusion with the broken 2.2.6 tarballs, I've simple changed the new filenames to use 2.2.6a.

A working libtool-2.2.6 is available now from, along with diffs and against libtool-2.2.4.  Please use a mirror to reduce stress on the main gnu machine:

Here are the compressed sources:

Here are the diffs against libtool-2.2.4:

Here are the gpg detached signatures:

You should download the signature named after any tarball you download, and then verify its integrity with, for example:

 gpg --verify libtool-2.2.6a.tar.lzma.sig

Here are the MD5 and SHA1 checksums (note these are different to
yesterdays broken release):

 8fb591cc2e995b1ce14d95206e33df3cf611639e libtool-2.2.4-2.2.6a.diff.gz

This release was bootstrapped with autconf-2.62 and automake-1.10.1, but is useable with any reasonably modern equivalents in your own projects.

Alternatively, you can fetch the unbootstrapped source code with
git by using the following command:

 $ git clone git://
 $ cd libtool
 $ git checkout v2.2.6a

You will then need to have the latest release versions of Automake (1.10.1) and Autoconf (2.62) installed to bootstrap the checked out sources yourself.

Please report bugs to <>, along with the verbose output of any failed test groups, and the output from `./libtool --config.' The README file explains how to capture the verbose test output.
