could this json lib work on windows?

[PinkGabriel]

I download the zip on windows, and use cmake in minGW to generate .sln, then compile in VS2015, but I got more than 100 errors.

I saw this in readme:
Though it's 2016 already, the support for C++11 is still a bit sparse. Currently, the following compilers are known to work:
GCC 4.9 - 7.1 (and possibly later)
Clang 3.4 - 3.9 (and possibly later)
Microsoft Visual C++ 2015 / Build Tools 14.0.25123.0 (and possibly later)
Microsoft Visual C++ 2017 / Build Tools 15.1.548.43366 (and possibly later)

My VS2015 version is community 14.0.25431，I'm not sure where the problem is.
Thanks~

Well the unit tests can be compiled and executed without errors, see https://ci.appveyor.com/project/nlohmann/json/build/2088/job/frx8pqcatlvi6goa

Could you provide more information?

[itviewer]

if you want use this lib，you just only need download json.hpp，not the whole repository https://raw.githubusercontent.com/nlohmann/json/develop/src/json.hpp

[PinkGabriel]

thanks for your reply!
The errors reported are all from json_unit, I tried cmake again, found that I missed this information:

$ cmake ..

I don't know whether it's right til this step. Then I build the project in VS, the errors reported are these:

thanks for your attention!

@itviewer thank you for your help!
I haven't used this kind of lib before so I cmake, compile the project as usual. Then is it all right that I ignore these errors and use the header file directly?

[itviewer]

@PinkGabriel yes, all other files only used for develop or test json.hpp，you only need json.hpp to develop your Project

[PinkGabriel]

@itviewer thanks, I'll follow the readme and have a try.

[nlohmann]

Any news on this?

[PinkGabriel]

@nlohmann Sorry for the delay!
I just ignored the errors reported in VS, now I'm using the lib refer to the readme, no problems til now. The stl-style api is easy to use. If I get problems in future, I'll ask for help again~
This issue could be closed. Thank you so much!

Thanks for checking back!
