nlohmann::json namespace error

[Thriliriel]

Hello. I installed nlohmann with vcpkg and configured the project in Visual Studio Community (includes and linkers alike). It seems all good, since the project can find the included headers (such as #include <nlohmann/json.hpp>) and all. However, the nlohmann::json raises a E0276 error: C++ name followed by '::' must be a class or namespace name. I also tried to download and include only the json header itself, but the error persists. Any ideas about what to do?

What is the line there? Does it involve the words new, min, or max? Those are the things most often #defined in another header that has been included before nlohmann/json.hpp.

Thanks for the answer. Following your suggestion, i think the problem was another library which was included before nlohmann.
