Abseil linking issues while building from scratch

[sevaserg]

What version of protobuf and what language are you using? Version: main Language: C++

What operating system (Linux, Windows, ...) and version? MacOS Sonoma 14.3.1 What runtime / compiler are you using (e.g., python version or gcc version) cmake 3.30.0 + Apple clang 15.0.0 (clang-1500.1.0.2.5) What did you do?

git clone https://github.com/protocolbuffers/protobuf
cd protobuf
mkdir build
cd build
cmake ..

What did you expect to see A proper build setup, so I could launch

make install

What did you see instead?

CMake Warning at third_party/abseil-cpp/CMakeLists.txt:82 (message):
  A future Abseil release will default ABSL_PROPAGATE_CXX_STD to ON for CMake
  3.8 and up.  We recommend enabling this option to ensure your project still
  builds correctly.

  The link interface of target "random_mocking_bit_gen" contains:

    absl::random_internal_mock_overload_set

  but the target was not found.  Possible reasons include:

    * There is a typo in the target name.
    * A find_package call is missing for an IMPORTED target.
    * An ALIAS target is missing.

Anything else we should know about your project / environment Before attempting doing anything I have intentionally removed protobuf and abseil previously installed by brew:

 % brew uninstall protobuf
Uninstalling /opt/homebrew/Cellar/protobuf/27.1... (430 files, 14.6MB)
==> Autoremoving 1 unneeded formula:
abseil
Uninstalling /opt/homebrew/Cellar/abseil/20240116.2... (748 files, 10.9MB)

I have discovered that setting ABSL_BUILD_TESTING to ON fixes the problem with this step, but it still looks like an issue to be fixed. But when I call

cmake .. -DABSL_BUILD_TESTING=ON -DCMAKE_CXX_STANDARD=17 && make install

I get this output:

error: static assertion failed due to requirement '!absl::is_trivially_relocatable<S>::value': 
  static_assert(!absl::is_trivially_relocatable<S>::value, "");
