GNU libtool-2.4.5 released [stable]

[Gary V. Vaughan]

Libtoolers!

The Libtool Team is pleased to announce the release of libtool 2.4.5.

GNU Libtool hides the complexity of using shared libraries behind a
consistent, portable interface. GNU Libtool ships with GNU libltdl, which
hides the complexity of loading dynamic runtime libraries (modules)
behind a consistent, portable interface.

This is a bugfix release and a recommended upgrade for all users.  Most
likely, this will be the last release that supports copying the libltdl
sources directly into your project -- libltdl is widely deployed now, and
there is absolutely no reason to give it special treatment compared to
any other library a project depends on.

Here are the compressed sources:

[*] Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact.  First, be sure to download both the .sig file
and the corresponding tarball.  Then, run a command like this:

  gpg --verify libtool-2.4.5.tar.gz.sig

If that command fails because you don't have the required public key,
then run this command to import it:

  gpg --keyserver keys.gnupg.net --recv-keys 151308092983D606

and rerun the 'gpg --verify' command.

This release was bootstrapped with the following tools:
  Autoconf 2.69
  Automake 1.15
  Gnulib v0.1-336-g342d9f0

NEWS

* Noteworthy changes in release 2.4.5 (2015-01-19) [stable]

** New features:

  - Libtoolize searches for the best available M4 on the user PATH at
    runtime, rather than settling for the first one found.

  - Support munging sys_lib_dlsearch_path_spec with LT_SYS_LIBRARY_PATH
    environment variable.

** Bug fixes:

  - Bail out at configure time if the installed M4 is not sufficient
    for the purposes of libtoolize.

  - freebsd-elf library versioning was upgraded incorrectly in 2.4.4,
    but now works properly again.

  - Fix a 2.4.4 regression so that libltdl subprojects do not warn
    about missing libltdl/libltdl directory as in prior releases.

  - When using Sun C++ on Solaris or GNU/Linux we used to set libtool's
    postdeps permanently, based on the contents of $CXX and $CXXFLAGS at
    configure time, which was brittle and error-prone.  Now, we no
    longer check for a SunCC ABI at configure time, but augment the
    postdeps at libtool time based on the current invocation flags on
    each call.

** Changes in supported systems or compilers:

  - /usr/local prefixed rpaths are now added to the link-line on
    ia64-hp-hpux*, because the default system runtime loader path does
    not contain them.

  - Previously, when using Sun C++ on Solaris or GNU/Linux, `-Cstd -Crun`
    flags were added to $postdeps unless CXX or CXXFLAGS contained
    `-library=stlport4`.  Newer releases have added other compiler flags
    that are also incompatible with `-Cstd -Crun`, so now we don't add
    them if any of `-std=c++[0-9][0-9]`, `-library=stdcxx4` or
    `-compat=g` were found in CXX or CXXFLAGS when the Sun C++ compiler
    is detected.



Enjoy!
