Libtoolers!

The Libtool Team is pleased to announce the release of libtool 2.6.1, a beta release.

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.

There have been 34 commits by 14 people in the 37 weeks since 2.6.0.

See the NEWS below for a brief summary.

Here are the SHA256 and SHA3-256 checksums:

  File: libtool-2.6.1.tar.gz
  SHA256 sum:   52264ab2fca9464dea9f6a0355d39e49b18f40468b9b6dbc3d151a0dba307a4b
  SHA3-256 sum: 59826fb74043179c38a393448b92dfcdfbe9046fd3b23a7079665984f22d6688

  File: libtool-2.6.1.tar.xz
  SHA256 sum:   3fb21f1e99fcdd8565c9b00fb1371db457b82a0da7cba273e1617c954b0ad1ee
  SHA3-256 sum: 614bc3ed43293be989ec3305dae42fc4e81234429477490734a40f6d3316560b

Verify the SHA256 checksum with either sha256sum, sha256, or
'shasum -a 256'.

Verify the SHA3-256 checksum with 'cksum -a sha3 -l 256 --base64'
from coreutils-9.8.

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-2.6.1.tar.gz.sig

The signature should match the fingerprint of the following key:

  pub   rsa4096 2021-09-23 [SC]
        FA26 CA78 4BE1 8892 7F22  B99F 6570 EA01 146F 7354
  uid   Ileana Dumitrescu <ileanadumitrescu95@gmail.com>
  uid   Ileana Dumitrescu <ileanadumi95@protonmail.com>

If that command fails because you don't have the required public key,
or that public key has expired, try the following commands to retrieve
or refresh it, and then rerun the 'gpg --verify' command.

  gpg --locate-external-key ileanadumitrescu95@gmail.com

  gpg --recv-keys 6570EA01146F7354

  wget -q -O- 'https://savannah. ... ol&download=1' | gpg --import -

As a last resort to find the key, you can try the official GNU
keyring:

  wget -q https://ftp.gnu.o ... u/gnu-keyring.gpg
  gpg --keyring gnu-keyring.gpg --verify libtool-2.6.1.tar.gz.sig

This release is based on the libtool git repository, available as

  git clone https://https.git ... g/git/libtool.git

with commit 79de7bb71bc0a1167f4c4ae8bd897976a0ff2b51 tagged as v2.6.1.

NEWS

** New features:

  - Pass 'resource-dir=*' flag for Clang.

  - Recognise explicit shared library arguments when linking dependency
    libraries to a shared library, like exists when linking a program.

  - Support OpenMP with macOS clang by processing '-Xpreprocessor
    -fopenmp' as one token.

** Bug fixes:

  - Store cygpath file path conversions correctly for MSYS2 and MSVC.

  - Fix syntax error in LT_PROG_OBJC and LT_PROG_OBJCXX.

  - Separate Objective C and C++ cache check for proper tagging support.

  - Fix in darwin to support values with spaces.

  - Limit the length of DLL name to 8.3 correctly to avoid corrupting a
    generated DLL on OS/2.

  - Remove unused variable on OS/2, which could cause issues with static
    library generation if defined.

  - Recognise more static linking options for Clang.

  - Fix emscripten CXX postdeps using non-PIC sysroot.

  - Avoid deprecated option '-o' with MSVC compilers and replace with '-Fe'.

  - Avoid overlinking of dependency libraries on ELF systems.

  - Ensure old libraries are not archived.

** Changes in supported systems or compilers:

  - Add support for SlimCC compiler.

  - Add support for *-ironclad-gnu.

Enjoy!
