Dear Gromacs Users,
I just installed Gromacs on my windows
machine (with a gromacs especially for Windows XPdownloaded) from your
website.
Everything seemed to go fine with the installation and there
is no problem when I execute pdb2gmx, editconf and genbox.
But, when
I execute grompp, I get this error :
...

Here's the problem. grompp calls your cpp with an include directory (the
-I flag) that has a space in it. You can see this is the problem in
the line after "calling cpp..." since cpp doesn't understand what comes
after the space.
The quickest work-around is to put gromacs in a folder with no space in
the filename. Then fix the environment variables.
More generally effective and certain to lead to less heartache in the
long run is to install Cygwin and following my HOWTO on installing
Gromacs under Cygwin. Now you have a full Unix compatibility layer and
can re-use all of the existing collective knowledge base of using
Gromacs under Unix, instead of finding new corners on the wheel to
"bounce over" all the time.
