Compiling GMIN with CHARMM

So, you want to get the latest version of GMIN from the Wales Group repository. The GMIN code is managed by Subversion version control (SVN), and before you can access it, you need an account on the departmental SVN server.

Getting an account on the SVN server

The SVN server we use is run by the good people in the Unilever Centre, so you should email ucc-support@ch.cam.ac.uk, CCing in David (dw34) to request access to the Wales Group repository. Make sure you include your CRSID, the bit before @cam.ac.uk in your email address.

Once they reply, you should be able to set up your password here after logging into Raven. To check you have access to the repository, try logging in here. If you can't, you've done something wrong! Get help!

Setting up your SVN details

Now, you need to specify some locations in your .bashrc file as environment variables. We do this as follows:

vi ~/.bashrc

This opens the vi editor. Press SHIFT+G to go to the bottom of the file, then press I to enter insert mode. Add the following to the bottom:

export SVN=https://wwmm.ch.cam.ac.uk/svn2/groups/wales/
export MYSVN=https://wwmm.ch.cam.ac.uk/svn2/users/CRSID/

where CRSID is the user name you use to log into Raven with. When you're done, we need to save he changes, press ESC to exit insert mode (check 'Insert' isn't still showing at the bottom!) and then type:

:wq

and press ENTER. This should exit the editor, and return you to the directory you were in before. These variables will now be automatically set when you open a new shell, but for now, we need to load them manually. We do this using the source command:

source ~/.bashrc
