CJ fails with VS 16.8

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   With our application compiled with VS 16.8 and C++20 enabled (/std:c++latest) the included CJ #includes fail to compile.

Some of the errors can be fixed by more forward declarations and some my qualifying members by classname, but I gave up when I ran into a circular dependency.

Can someone look into this?

	Using the /permissive compiler flag enabled building the application with /std:c++latest for us. Note that this will prevent the use of C++20 Modules. Reference: https://devblogs.microsoft.com/cppblog/standard-c20-modules-support-with-msvc-in-visual-studio-2019-version-16-8/ Codejock reports that most of the standard compliance issues will be addressed in version 20 (due spring 2021) but that support for /std:c++latest is never guaranteed.
