.. OK. Again, the shipping Win32 version of cpp.exe is perfectly working with Gromacs 64-bit on a opetron m/c which is a x86-64 box. But I guess it (the above cpp.exe) may not work on pure x64 m/c as its not a valid x64 application. Is there a x64 port of cpp.exe is available ? Can we use other (native windows) c preprocessor ? Sorry, if I'm making silly queries. Thank you Hi Utkal, Cpp.exe is called by grompp to preprocess the topology.
