The fourth (and hopefully final) RC for the 1.86.0 Beta release is now available.

The SHA256 checksums are as follows:

Changed libraries between RC2 and RC4: Boost.Process fixed some build issues on Windows

As always, the release managers would appreciate it if you download the candidate of your choice and give building it a try. Please report both success and failure, and anything else that is noteworthy.

I have built the boost libraries on a x86_64 machine running Mac OS X 14.5 using "Apple clang version 15.0.0 (clang-1500.3.9.4)” The libraries were built successfully using C++11/14/17/20/2B. However, when building for C++03, the following libraries failed to build * contract * graph * program_options * serialization * test * thread — Marshall

I successfully built the libraries on x86_64 RHEL 9.4 using GCC 11.4.1 with cxxstd=11,14,17,20,2b. Matt

I attempted to build the libraries with homebrew LLVM 18.1.8 on an M1 Pro Mac running macOS 14.5, but Boost.Cobalt and Boost.Log both fail to build because of: Undefined symbols for architecture arm64: "std::exception_ptr::__from_native_exception_pointer(void*)", referenced from: std::exception_ptr std::make_exception_ptr[abi:ne180100]boost::system::error_code(boost::system::error_code) in exception.o boost::asio::detail::thread_info_base::capture_current_exception() in main.o "___cxa_init_primary_exception", referenced from: std::exception_ptr std::make_exception_ptr[abi:ne180100]boost::system::error_code(boost::system::error_code) in exception.o boost::asio::detail::thread_info_base::capture_current_exception() in main.o ld: symbol(s) not found for architecture arm64 I have opened an issue against homebrew here: https://github.com/Homebrew/homebrew-core/issues/178435. There are linked LLVM issues, and a comment from a Homebrew maintainer that says a workaround has already been applied to brewed LLVM to fix the LLVM issues. On the positive homebrew GCC-14 and Xcode provided clang 15.0.0 both successfully build the libraries. Matt
