It is like the paradiseo compilation is not supporting the make_from_tuple function, despite the building and installation of the framework was correct.
Hello, I built and installed paradiseo-3.0.0-beta and now I am having a problem trying to build my own code. Examples below.
CMakeList.txt:
main.cpp:
The
cmake ..command output is:and the
makeoutput is:It is like the paradiseo compilation is not supporting the
make_from_tuplefunction, despite the building and installation of the framework was correct.Well, any idea about what is happening here?
All the best;
