It seems Parscale is not able to correctly call the functions in the LIGGGHTS namespace.
After running ./refresh.sh in src,

When I checked modify.cpp in the LIGGGHTS source directory it did not contain the definition for find_fix_style_strict (second error message). However, that definition was contained in modify_liggghts.cpp which did not have a header file. I tried to include the .cpp in coupling_model_liggghts.cpp but it caused a ton more errors to appear. I've checked the includes on coupling_model_liggghts.cpp and coupling_model_liggghts.h and I'm fairly sure they lead to the right places but the problem still persists. Any ideas on what the problem could be?
