"make" error when building nana for c++

Question

I've been trying to install the nana library for c++. I've used these guides: https://github.com/qPCR4vir/nana-docs/wiki/Installation

https://github.com/qPCR4vir/nana-docs/wiki/Install-and-use-nana-with-mingw---step-by-step

I got stuck on the part that says "Create a static linkage library solution within a IDE/build system you use, and add all the files which are placed in NanaPath/source and in all its sub directories to the project. Then compile the solution and you will get a static linkage file NanaStatic in a path similar to NanaPath/build/bin/IDEName."

I downloaded MinGW, git, and cmake like it said. I opened up the bat file, ran the "git clone" with the link, ran

cmake -G "MinGW Makefiles"

It did it's thing and finished successfully. Then I tried running "make" and it got to 6% when this showed up:

In file included from C:/Users/.../nana/verbose_prepocessor.hpp:99:0,
from C:\Users\...\nana\source\deploy.cpp:242:C/Users/.../nana/include/filesystem/filesystem.hpp:71:39: fatal error: experimental/filesystem: No such file or directory
#    include<experimental/filesystem>
                                     ^
compilation terminated.
make[2]: *** [CMakeFiles\nana.dir\build.make:163: CMakeFiles/nana.dir/source/deploy.cpp.obj] Error 1
make[1]: *** [CMakeFiles\Makefile2:67: CMakeFiles/nana.dir/all] Error 2
make: *** [Makefile:129: all] Error 2

I tried using a different source of the code (git and sourceforge) and that didn't make a difference. I tried using the GUI cmake, but I had other errors with that not recognizing MinGW. I looked around for answers online, but they mostly led back to the guides I was using. I checked my GCC and G++ version with gcc/g++ --version, and they're both 6.3.0.

I'll take any suggestions/advice, thanks!

I have not used Eclipse, so I cant help with that. But I will try to help with nana:

Originaly there was no std::filesystem and nana offered one JinHao invented. With the apparition of std::experimental::filsystem candidate, an experimental filesystem in the sdt:: c++ library of some versions of some compilers we adapted the nana filesystem to be a partial implementation of that. Then nana try to configure itself to use the provided std:: (or Boost) implementation or if it is not there then nana::filesystem. It seems like MinGW have problems with filesystem, I'm not sure about that but here you can read: https://github.com/Alexpux/MINGW-packages/issues/2292

Please try to undertstand what is going on in your case an let us know about. We will then try to fix the configuration of nana to work even in that situation. You can always simply choise to (force) use the nana implementation. Just please compile both the nana library and your project with all the same options, including what filesytem you use. For example adding -DNANA_CMAKE_NANA_FILESYSTEM_FORCE=True to your cmake or define NANA_FILESYSTEM_FORCE in your built system (or IDE).
