Absl compilation error in Visual Studio 2022 - 17.7.3

[Diddlik]

What version of OR-Tools and what language are you using?
Version: 9.6 / 9.7
Language: C++

Which solver are you using (e.g. CP-SAT, Routing Solver, GLOP, BOP, Gurobi)
GLOP

What operating system (Linux, Windows, ...) and version?
Windows 11

What did you do?
Updated Visual Studio 2022 from version 17.5.3 to 17.7.3.
Tried compiling the project which uses OR-Tools library.
See compilation errors.

If I open the same solution file on the same computer but with VS 17.5.3 then it compiles without errors.
Tried both C++ 20 and C++17

What did you expect to see
Successful compilation without any errors, similar to the behavior in Visual Studio 2022 version 17.5.3.

What did you see instead?
Received multiple errors, for instance:
Error C2574 '(__cdecl *absl::lts_20230125::time_internal::cctz::detail::civil_timeabsl::lts_20230125::time_internal::cctz::detail::day_tag::civil_time(void))(void)': cannot be declared static (compiling source file Source\ML_Solver_Args.cpp) GLOP_Lib I:\Coding\DGO\GLOP_Lib\include\absl\time\internal\cctz\include\cctz\civil_time_detail.h 408

Make sure you include information that can help us debug (full error message, model Proto).

Anything else we should know about your project / environment

I have the same problem in VS 17.7.3. Removing parenthesis around min and max in lines 404 and 408 will fix the issue. Anyway, I have no idea why this error occurred.

[Diddlik]

thanks, now it compiles.

[evakili]

You should be aware that removing those parentheses may cause conflicts with min or max macros defined in other headers (e.g. Windows.h). Those parentheses are there to manage those conflicts. This means that removing parentheses is only a workaround, not a solution.

So what is the proper solution?
