| The instructions on this page are a summary of the GEOS-5 tutorial Arlindo da Silva has been presenting. For the moment, we presume that the user has an account on '''sourcemotel''' and access to the NCCS machines (e.g., '''discover''').
| | These are checkout and build instructions for GEOS-5. We presume that the user has an account and appropriate permissions on '''cvsacl''' to check code out, and access to the NCCS machines (e.g., '''discover''') to build and run code. |

| The GEOS-5 (AGCM) source code checks out at about 40 MB of space. Once compiled, the complete package is about 500 MB. Your home space on '''discover''' may not be sufficient for checking out and building the code. You should consider either requesting either a larger quota in your home space (call the tag x6-9120 and ask, telling them you are doing GEOS-5 development work) or building in your (larger) nobackup space. But consider, ''nobackup'' is not backed up. So be careful...

| === Setup your environment to check out code ===
| |
| With the above step complete, let's get ourselves ready to check out the code. We'll be using the UNIX ''cvs'' command to check out the code. The basic syntax is:
| |
| | |
| % cvs -d $CVSROOT checkout -r TAGNAME MODULENAME
| |
| | |
| Here, $CVSROOT specifies the CVS repository we'll be getting the code from, MODULENAME is the particular module (set of code) we'll be checking out, and TAGNAME is a particular version of that module. Let's fill in the blanks:
| |
| | |
| % cvs -d :ext:c-sourcemotel.gsfc.nasa.gov:/cvsroot/esma co -r GEOSdas-2_1_6 GEOSagcm
| |
| | |
| So our module is ''GEOSagcm'' and the tag is ''GEOSdas-2_1_6''. Note that I substituted the shortcut ''co'' for ''checkout'' in the above command.
| |
| | |
| The above command is generally valid. You ought to be able to execute it and checkout some code. If you don't have your ''ssh keys'' setup on '''sourcemotel''' then you should be prompted for your '''sourcemotel''' password. The assumption here is that your username on '''sourcemotel''' is the same as on the machine you are checking the code out on. If not, modify the command like this:
| |
| | |
| % cvs -d :ext:SOURCEMOTEL_USERNAME@c-sourcemotel.gsfc.nasa.gov:/cvsroot/esma co -r GEOSdas-2_1_6 GEOSagcm
| |
| | |
| Here's a short cuts. So that you don't have to type in the ''-d :ext:c-sourcemotel.gsfc.nasa.gov:/cvsroot/esma'' business all the time, you can add the following lines to your, e.g., ''.cshrc'' file:
| |
| | |
| setenv CVSROOT ':ext:c-sourcemotel.gsfc.nasa.gov:/cvsroot/esma'
| |
| setenv CVS_RSH ssh
| |
| | |
| Modify as appropriate if you need to put your username in or if you use a different shell (i.e., put the analog of these lines into your .bashrc file or whatever).
| |
| | |
| If you set that up, you should be able now to type in:
| |
| | |
| % cvs co -r GEOSdas-2_1_6 GEOSagcm
| |
| | |
| Enter your password when prompted and the code should check out.
| |
| | |
| If you want to avoid typing in your password all the time (recommended) you need to set up your ''ssh keys''. There are some good instructions on this [[here]]. Once you have created your keys on the local machine (i.e., '''discover''') you want to give '''sourcemotel''' the contents of the public key file (~/.ssh/id_dsa.pub). Log on to '''sourcemotel''' in your browser and click on the "My Page" tab and then on the "Account Maintenance" heading. Scroll down the page and you'll see a little block called "Shell Account Information." Inside that is a link to "Edit Keys." Click the link and then paste the contents of your id_dsa.pub file as a new line into the window. Click "Update" and you're good to go. It may take 10-15 minutes for '''sourcemotel''' to propagate the updated keys, so until that happens you may still have to type in your password.
