where does instanton.o come from?

greetings,

i was asked recently to compile a new version of vasp (4.6) including the vtst tools version 2.03b. i made the necessary mods to the makefile but was suspicious of the instanton.o object on the SOURCE line as i knew there was no instanton.F file for which to process. of course the make failed with the following error: make: *** No rule to make target `instanton.o', needed by `vasp'. Stop.

i removed this object from the SOURCE line and make ran successfully. any insight regarding instanton.o would be appreciated.

Ah, yes, instanton.F was added in a later version. You are right to remove the instanton.o from the makefile for earlier versions.

This module provides a method to calculate quantum tunneling rates.

greetings,

thank you for the response. i will let the requesting user know that if they require this they need to get me newer code.
