I'm trying to run the code in the answer here, but I've got the following error:
fatal error: filesystem: No such file or directory
Here is a similar question, and I applied all the steps in the answer, but it doesn't work.
More details about my environment:
My operating system is Windows 10.
I installed codeblocks-17.12mingw-setup.exe from this link.
I set the option:
Have g++ follow the coming C++1z (aka C++17) ISO C++ language standard [-std=c++1z]
The result of executing the command "g++ --version" is: "g++ (MinGW.org GCC-8.2.0-3) 8.2.0"
