Compile the code

We'll walk you through the compilation of "exp4" which simulates zonal flow over a Gaussian bump.

From the top-level source directory, where you installed the code, cd to verification/exp4:

% cd verification/exp4

There are four dsub-directories and a REAME file.

CVS/ is where version information is stored by CVS. You should never need to enter/read/change this.

Please don't delete this directory/information.

code/ contains copies of the source code unique to this experiment that over-ride the originals. This is our way of customizing the code.
input/ contains the input files and parameters for this experiment.
results/ contains a single text file, output.txt, which we use for quickly assessing the state of the code.

Now cd into input/ and run the configuration tool genmake:

% cd input

% ../../../tools/genmake -mods=../code

% make depend

genmake will create a file Makefile and report which packages are being included/excluded. make depend figures out the file dependancies that allows make to work efficiently. You'll also notice the number of files in the current directory has greatly expanded. This are all symbolic links to the original source code.

You only need to do the above steps once; here after, you can edit the code and re-compile with make.

Compile and link the code:

% make

This will take some time, depending on your system. [Hint: compiling on remotely mounted disks is often really slow]

If all goes well, you're ready to run the model...
