Mixing /std configurations of VC++ projects

Assuming I have 2 VC++ projects:

  • Project1.dll
  • Project2.dll

Project1 is dependent on Project2.

This is using VS2020.

If Project2 is built using /std:c++14 and Project1 is using /std:c++20.

Will there be an issue on this?

I have read about ABI compatibility starting from VS2015 up to the latest but this part, the language standard, is the one I am not sure yet.

Thank you.

I have read

C++
C++
A high-level, general-purpose programming language, created as an extension of the C programming language, that has object-oriented, generic, and functional features in addition to facilities for low-level memory manipulation.

    Hi @Barias, Abe [AUTOSOL/SYSS/MNL] ,

    I wrote a demo for testing according to your description, and the program has no errors, so in most cases you don't have to worry about this problem.

    In my opinion, your question is closer to compatibility between C++ standards, I suggest you read this issue carefully.

    Best regards,
