Hi all,
I’m currently trying to make use of some functions in the Integrate class from within another class. however when I try to compile the module using the call (in the form of update->integrate->ev_set()) I get compilation errors saying things like:
error: invalid use of incomplete type ‘struct LAMMPS_NS::Integrate’
error: forward declaration of ‘struct LAMMPS_NS::Integrate’
This happens despite inheriting from the Pointers class, which as I understand it should include a pointer to the update object, and thus a means of accessing the functionality in Integrate. The only thing that occurs to me is that ev_set() is a protected function and so it may be an encapsulation issue I’m running into. At the same time, I’m hesitant to modify the integrate.cpp/h files to make my class a friend, so I would greatly appreciate it if someone could help me understand this issue and offer a solution to correct it, ideally with a minimum of alteration to LAMMPS base classes.
Thanks,
