libtorrent version (or branch)

v2.0.0

platform/architecture

MSVC x64

compiler and compiler version

  • MSVC 16.7.2 19.27/14.27

Libraries/tools:

  • OpenSSL 1.1.1g
  • Boost 1.73.0
  • CMake 3.18.2

please describe what symptom you see, what you would expect to see instead and
how to reproduce it.

Follow up to #5111 (comment) and #5111 (comment); compilation is successful but there are some warnings/excessive compilation output noise. Not sure what is the impact/severity of these warnings in practical terms, but they could be fixed.

  • Without specified CMAKE_CXX_STANDARD:

Config command:

cmake -S . -B cmake-build-dir -G "Ninja Multi-Config" -DCMAKE_TOOLCHAIN_FILE=G:/vcpkg/scripts/buildsystems/vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-windows-static -Dbuild_examples=ON -Dbuild_tools=ON -Ddeprecated-functions=OFF -Dstatic_runtime=ON -DBUILD_SHARED_LIBS=OFF

Build output (release build):

(Note the possible loss of data warnings and the output noise from cl : Command line warning D9025 : overriding '/W3' with '/W4'. Pretty sure the latter can be fixed by using target_compile_options() instead of add_compile_options() to set /W4. If no one tackles this in the meantime, I'll give it a shot in the near future.)

(Note the very noisy warnings about C++17 deprecations.)

add /Zc:__cplusplus to c++ command line additional options

cl : Command line warning D9025 : overriding '/W3' with '/W4'

That smells like some issue in the cmake file. There's no such warning when building with b2.

as for

warning STL4007: Many result_type typedefs and all argument_type, first_argument_type, and second_argument_type typedefs are deprecated in C++17. You can define _SILENCE_CXX17_ADAPTOR_TYPEDEFS_DEPRECATION_WARNING or _SILENCE_ALL_CXX17_DEPRECATION_WARNINGS to acknowledge that you have received this warning.

You'll notice that this is handled by only using that typedef if __cplusplus < 201402. Presumably this is fundamentally caused by __cplusplus being incorrectly defined in msvc. There's a flag to fix that, which the cmake file probably should set.

It is indeed an issue with CMake (as reported here: https://gitlab.kitware.com/cmake/cmake/-/issues/18317). It can be fixed by adding cmake_policy(SET CMP0092 NEW) - which, if added would require one to set their own warning levels.

@arvidn @vktr

I no longer get the __cplusplus-related warnings. Probably because of recent fixes in the newer MSVC 16.8.x (19.28/14.28) versions. Looks like their efforts to increase standards compliance and implementation correctness are paying off.

I submitted #5336 to fix the warning flags override warnings by setting CMP0092 to new - it does seem like the better, more elegant way to solve this problem. This required bumping the minimum required CMake version to 3.15. I think this is pretty reasonable, but let me know if it is not desirable.

@arvidn I promise I have not forgotten about my other Actions PR. The new information in this post turned this into low-hanging fruit that I'm able to pick immediately, as it turns out that it is not contingent on a refactoring to use more target_* commands instead of add_* commands, which is a larger undertaking (but also one I'd like to address eventually).

Silly me, I was not actually passing -DCMAKE_CXX_STANDARD=17. I still get those warnings. I'll fix up the PR to also fix that.
