==Install g95 (deprecated)==

This Fortran compiler works in cygwin/Windows. In theory, you should be able to install other Fortran compilers instead, but I just didn't have luck with the others I tried. If you don't know what compiling is, read [[#Compile ROMS|Compile ROMS]] below.

:*Go to the [http://ftp.g95.org/ g95-project website] and download the G95 binaries. Or simply [http://ftp.g95.org/g95-x86-cygwin.tgz click here] to start the download.
:*Save it inside the cygwin folder (C:\cygwin in this tutorial).
:*Now you have to open cygwin and go to the place where you saved the g95-x86-cygwin.tgz file. Here you need to know that cygwin uses the folder C:\cygwin\cygdrive as a pseudo-drive. When cygwin starts, you will be able to see all your files and folders that you have in your Windows-user root (''i.e.'' C:\Users\Administrator\), but they will appear to be in a different location (i.e. /cygwin/cygdrive/c/Users/Administrator/ ). This is just cygwin's way to emulate a Linux-type hard-drive inside Windows.

{{warning}}IMPORTANT to keep in mind:

:*Cygwin's home directory, which is where cygwin opens by default is, in this example, /cygwin/cygdrive/c/Users/Administrator/ but when in it, cygwin abbreviates it as ~
:*Cygwin's HOME directory (i.e. ~) = C:\Users\Administrator\ in Windows Explorer
:*Cygwin's ROOT directory (i.e. /) = C:\cygwin\ in Windows Explorer

{{note}}'''Useful Notes:'''
:*PASTE: To paste text in the cygwin window, right-click on the cygwin symbol on the left-upper corner of the window. Chose Edit > Paste.
:*Here are some websites where you can learn more Linux commands
:**[http://www.howtoforge.com/useful_linux_commands http://www.howtoforge.com/useful_linux_commands]
:**[http://www.tuxfiles.org/linuxhelp/cli.html http://www.tuxfiles.org/linuxhelp/cli.html]

Open cygwin and go to the root directory. To do this type cd / (cd = command for: 'change directory'). Now that you are in the root directory, type ls (command for: "show contents of this directory"), you should see our recently downloaded g95-x86-cygwin.tgz file.

:*Extract (or unzip) g95-x86-cygwin.tgz by typing:
::<div class="box">tar -xvzf g95-x86-cygwin.tgz</div>

:*Move g95-x86-cygwin.tgz to a safe location:
::<div class="box">cd ~ mkdir software mv /g95-x86-cygwin.tgz software/</div>
{{warning}}IMPORTANT: It is essential that you run the above command from the root ( / ) directory. Otherwise g95 will not be installed where you expect it to be.

:*This should install g95 in /usr/local/bin and its documentation in /usr/local/doc/g95

==Install NetCDF (Deprecated configure line)==
:<div class="box">CC=gcc FC=g95 F77=g95 CPPFLAGS='-DNDEBUG -DpgiFortran' \ FFLAGS=-fno-second-underscore FCFLAGS=-fno-second-underscore ./configure</div>

==Customizing the [[build Script|Build Script]] (Deprecated section)==

:*We are compiling in serial using the g95 compiler so make your build.bash match the following:
::<div class="box">export USE_MPI= export USE_MPIF90= export FORT=g95</div>
