libtool-1.0 is released
Gordon Matzigkeit
Hi, all!
The long-awaited version 1.0 of GNU libtool has finally been released.
For those who are new to libtool, the easiest way to describe libtool
is to say ``developers use it to make their packages build shared
libraries transparently.''
Libtool works best with GNU Autoconf and GNU Automake, but does not
require them. So, even if you maintain a non-GNU package, libtool may
be useful to you.
Here is an excerpt from the package README file:
======================================================================
This is GNU libtool, a generic library support script. Libtool hides
the complexity of using shared libraries behind a consistent
interface.
To use libtool, add the new generic library building commands to your
Makefile, Makefile.in, or Makefile.am. See the documentation for
details.
Libtool supports building static libraries on all platforms.
Shared library support has been implemented for these platforms:
All ELF targets that use both the GNU C compiler (gcc) and GNU ld
AIX 3.x (*-*-aix3*)
AIX 4.x (*-*-aix4*)
Digital/UNIX 3.x, 4.x, a.k.a. OSF/1 (*-*-osf3*, *-*-osf4*)
FreeBSD 2.x, 3.x (*-*-freebsd2*, *-*-freebsd3*)
HP-UX 9.x, 10.x (*-*-hpux9*, *-*-hpux10*)
IRIX 5.x, 6.x (*-*-irix5*, *-*-irix6*)
Linux ELF (*-*-linux*, except aout, coff, and oldld)
NetBSD 1.x (*-*-netbsd*)
OpenBSD 2.x (*-*-openbsd*)
SCO OpenServer 5.x (*-*-sco3.2v5*)
Solaris 2.x (*-*-solaris2*)
SunOS 4.x, a.k.a. Solaris 1.x (*-*-sunos4*)
======================================================================
For those who aren't new to libtool, here is a list of changes between
version 0.9 and 1.0, taken from the package NEWS file:
New in 1.0:
* Bug fixes.
* Better configuration test to find the system linker. The old test
was failing because people frequently install GNU ld, but don't
necessarily configure GCC to use it.
* Automake support for Libtool now uses the LTLIBRARIES primary. See
the Automake documentation for more information.
* Added new `--disable-static' flag to disable building static
libraries on platforms that have shared libs.
* New `-allow-undefined' link flag to build shared libs that contain
references to unresolved symbols.
* Removed all support for creating static-only libraries.
* Basic support for dynamically loaded modules: new `-export-dynamic'
linking flag and corresponding `dlname' mode.
* New `--features' flag to display configured libtool attributes.
* Added support for installing libtool objects, both in absolute and
relative directories.
* Support *-*-linux-gnu* as an alias for *-*-linux*.
* Support for *-*-openbsd* and *-*-freebsd3*.
The main distribution site for libtool is:
<URL:ftp://prep.ai.mit.edu/pub/gnu/libtool-1.0.tar.gz>
It is also available from your favourite GNU mirror.
Please report any bugs to the libtool mailing list,
<bug-l...@gnu.ai.mit.edu>. If you want to subscribe to this list,
send your request to <bug-libto...@gnu.ai.mit.edu>, and a human
(I) will add you.
Libtool would not be what it is today without the invaluable help of
these people:
Everybody who was kind enough to spend time testing libtool, use it in
their packages, and report bugs to me before libtool 1.0 was released.
