libtool-2.4.7 released [stable]

Item posted by Alex Ameen <growpotkin> on Thu 17 Mar 2022 04:32:13 AM UTC.

Howdy, Libtoolers!

After a long hiatus, the Libtool Team is pleased to announce the release of
libtool 2.4.7.

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.

Here are the compressed sources:
https://ftpmirror.gnu.org/libtool/libtool-2.4.7.tar.gz   (1.9MB)
https://ftpmirror.gnu.org/libtool/libtool-2.4.7.tar.xz   (996KB)

Here are the GPG detached signatures[*]:
https://ftpmirror.gnu.org/libtool/libtool-2.4.7.tar.gz.sig
https://ftpmirror.gnu.org/libtool/libtool-2.4.7.tar.xz.sig

Use a mirror for higher download bandwidth:

Here are the SHA1 and SHA256 checksums:

d3f2d5399f4bf5cbd974b812ebaca28d6492ca65 libtool-2.4.7.tar.gz
BOlsJATqcMWQxUbrpCAqThJyLGQAFsErmy8c49SB6ag libtool-2.4.7.tar.gz
0c90f1b046ea9cd7b32a4b5a6a9df4b46ddb637a libtool-2.4.7.tar.xz
T38hfwV85lX/IlWa0iGg/Y74StH8X8tpkM7MMzqhY10 libtool-2.4.7.tar.xz

The SHA256 checksum is base64 encoded, instead of the
hexadecimal encoding that most checksum tools default to.

[*] 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-2.4.7.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 6EAC957F8EEB55C0

and rerun the 'gpg --verify' command.

This release was bootstrapped with the following tools:
Autoconf 2.69
Automake 1.16.3
Gnulib a5218207e5

* Noteworthy changes in release 2.4.7 (2022-03-16) [stable]

** New features:

- Libtool script now supports (configure-time and runtime) ARFLAGS
    variable, which obsoletes AR_FLAGS. This is due to naming conventions
    among other *FLAGS and to be consistent with Automake's ARFLAGS.

- Gnulib testsuite is enabled and run during 'make check'.

- Support the Windows version of the Intel C Compiler (icl) in
    libtool script.

- Pass '-fsanitize=*' flags for GCC and LLVM, and '-specs=*' for GCC
    to linker.

- Pass '-Xassembler=*' and '-Wa,*' flag to compilers and linkers.

- The variable 'FILECMD' with default value of '/usr/bin/file' was used to
    replace existing hard coded references to '/usr/bin/file'.

- Add MidnightBSD support.

** Important incompatible changes:

- Libtool changed ARFLAGS/AR_FLAGS default from 'cru' to 'cr'.

- Do not pass '-pthread' to Solaris linker.

- 'libtool' and 'libtoolize' scripts now use '#! /usr/bin/env sh' shebang.
    Previously '#! /bin/sh' was used, which presents challenges for
    containerized environments.

** Bug fixes:

- Fix significant slowdown of libtoolize for certain projects (regression
    introduced in 2.4.3 release) caused by infinite m4 macro recursion.

- Mitigate the slowdown of libtool script (introduced in v2.4.3) caused by
    increased number of calls to '$SED $sed_quote_subst' (bug#20006).

- Properly parse and export TLS symbols on AIX.

- Various bug fixes surrounding use of 'sed'.

- Darwin systems set proper "allow undefined" flag on OSX 11, and
    PowerPC 10.5.

- Removed some deprecated tests related to 'Makefile.inc' files.

Enjoy!
