I am trying to compile and run the spline1d_d example from ALGLIB web page on MACOS using C++ Version 14 and cmake Version 3.14. (code is here: http://www.alglib.net/translator/man/manual.cpp.html#example_spline1d_d_cubic)

The compiler throws the below error message. Can please somebody help?

Includes from ALGLIB are being found as expected: include include

The COMPILER ERROR MESSAGE:

I think your using the wrong architecture. 64 bit or 32 bit. Another error about linking in c++ is that you didn't add reference path to c++ header files in project settings
