Conflicts with win32 header files on visual studio 2022 #1788

Open OptimumCpp opened 1 year ago

OptimumCpp commented 1 year ago

Compilation success depends on the order of includes. Fails if windows headers go 1st:

//compile failure:
#include <windows.h>
#include <range/v3/all.hpp>

The above code creates a lot of none-sence diagnostics. but if the order is reversed, everything works fine:

//compile success:
#include <range/v3/all.hpp>
#include <windows.h>

I guess the problem lies in ranges preprocessing. But since I am using external VCPKG, I cannot tell whether it is a problem on Microsoft port, or the ranges library has an issue.

thank you for making life easier.

@OptimumCpp , you can add NOMINMAX preprocessor definition in the build system. After that, it should compile.

I also notice that sometimes, some libraries do #define True. In that case, it is worth doing #undef True before ranges inclusion.

As I mentioned earlier, I mamged to build code with reordering includes, but I will try this workaround as well. But I guess True must be #undefd inside range headers.
