Boost 1.79, boost/container_hash/hash.hpp, error: 'unary_function<double, unsigned long>' is deprecated #224

Closed joaotavora closed 2 years ago

Hello,

I installed boost 1.79 through Conan:

[requires]
catch2/2.13.9
benchmark/1.6.1
cli11/2.2.0
boost/1.79.0

[generators]
cmake

My project wide compilation flags include -std=c++20 -Wall -Wextra -Werror. This apparently turns deprecated function warnings into errors. And somewhere along the line, unary_function was deprecated.

Any compilation with these flags which eventually attempts to include <conan's boost dir>/include/boost/container_hash/hash.hpp will result in lots of these errors, as the hash.hpp file seems to be used by many other files.

Here's the relevant clang++ invocation:

According to @pdimov, this is a dup of https://github.com/boostorg/container_hash/issues/22, which has a upcoming fix and a workaround. Closing.
