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: https://www.gnu.org/order/ftp.html 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 NEWS * 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!
