Could anyone tell me how to compile a patch into already installed Gromacs . I
have 3.3 in my system and want to comile a patch for secondary structure
prediction.
A non-expert can't sensibly modify an existing gromacs installation.
A correct approach to replace the installation would be to uninstall the
existing GROMACS, get the correct source distribution, unpack it, apply
the patch, and then use configure in the same way as the original
installation, plus any patch-specific things, then make and install
A superior approach is probably to make a second gromacs installation
with the patch applied, since it's likely that you will not want to use
this patch for all of your GROMACS work. Leave your existing
installation, get the source, unpack, patch and then when you configure,
have a look at "./configure --help" and choose a judicious combination
of "./configure --prefix=/your/choice/of/location
--program-suffix=_yoursuffix" and your usual configuration options, then
make and install. Now you have the option of sourcing the GMXRC from
/your/choice/of/location from your working shell when you want the
patched executables to be used, and you can be sure which version is
being used because you'll have to supply the suffix. For normal usage,
you just source the normal GMXRC in your .bashrc/.cshrc/whatever. This
also has the effect of isolating your normal GROMACS usage from any bugs
that the patch might introduce, which is an important consideration.
