Once again they are minor problems with the VS project file.
First you included the automatic update_project.py script, but apparently forgot to run it ;-)
The included VS project file has old incorrect source files associated with it.
Secondly the erfc file in the update_project.py is incorrectly indicated as "extra\efc_namd.c", while of course it should be "extra\erf_namd.c". And the update_project.py forget to included the header "extra\erf.h" file also.
I attached the corrected files.
After correcting this, the compilation works fine.
But when run, LIGGGTHS gives me the following warning:
WARNING: Non-contacting implementation missing (..\fix_contact_history.cpp:162)
Is this something I should worry about ?
