I have the latest stable version of LAMMPS which lammps-31Mar2017
I copied the USER-3SPN folder to mylammps/src dir.
then I turned to mylammps/src dir and typed
and then I turned to make folder and copied makefile.serial to mine subdir. and
modified it to include the FFTW3 LIB. linker and renamed it to makefile.aserial and returned to src dir and typed
but I got an error which is
../dihedral_3spn2.cpp: In member function ‘virtual void LAMMPS_NS::Dihedral3spn2::coeff(int, char**)’:
../dihedral_3spn2.cpp:299:52: error: no matching function for call to ‘LAMMPS_NS::Force::bounds(char*&, int&, int&, int&)’
and the compilation was terminated.
it is clear that the error because this package was not updated in order to fit the newest versions of LAMMPS program, but I sent to you hoping that I will find someone who dealt with this external package and has the solution.
