Compiler error C2737 in common.h

[lnxdx]

What Operating System(s) are you seeing this problem on?

Windows 11

dlib version

19.24.2

Python version

3.10

Compiler

MSVC 19.24.28316 for x64

Expected Behavior

I expect MSVC compiles dlib and produces installable python package.

Current Behavior

When trying to install dlib using pip install dlib command, MSVC report a compiler error C2737 which indicates constexpr object must be initialized. This error occurs on the line number 1040 of common.h file.

This is the full log:

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for dlib
Failed to build dlib
ERROR: Could not build wheels for dlib, which is required to install pyproject.toml-based projects

Steps to Reproduce

pip install dlib
Note that CMake is installed and is in PATH.

Anything else?

After unsuccessful installation for dlib 19.24.2, I finally downloaded dlib 19.24.0 from dlib website and installed it without producing any error. Note that the line which produces said error does not exist in version 19.24.0.

pip install dlib==19.24.0 works. But pip install dlib==19.24.2 doesn't!

That version of visual studio is too old. Try using a newer one like Visual Studio 17.
