Additional tip: if you don't want to rename all the executables
you may simply create a soft link to one of the install folders,
then -when need to change- remove it then re-create with the other one.
In detail: I have the following lines in my /home/myname/.bashrc:
I have two (in fact more) compiled versions: gromacs-4.6.6_bin and
gromacs-5.0_bin. When I want to use the 4.6.6 version:
rm -f ~/gromacs_bin
ln -s ~/gromacs-4.6.6_bin ~/gromacs_bin
Then to switch to the other:
rm -f ~/gromacs_bin
ln -s ~/gromacs-5.0_bin ~/gromacs_bin
If you're in a unix shell, you need to re-open it for .bashrc to take effect.
I assumed you're running GROMACS under some Linux/Unix platform
but probably the same can be achieved on any other OS.
Hope this helps,
