Mac instructions

1: Install FORTRAN compiler.

The preferred compiler would be gfortran found here: http://gcc.gnu.org/wiki/GFortranBinaries#MacOS OR http://hpc.sourceforge.net

But it may or may not be required to have additional library files associated with g77. Ignore installing g77 on your first attempt to compile krc on a mac, but compile g77 if errors associated with missing library files show up during the compilation. http://www.webmo.net/support/fortran_osx.html download the g77 compiler called g77-intel-bin.tar.gz (Intel Mac only) Then open a terminal window, go to the place where g77-intel-bin.tar.gz is located.

Type:

gunzip g77-intel-bin.tar.gz
sudo tar -xvf g77-intel-bin.tar -C /

GOOD NEWS: No modifications of Makefile were required for version 2.3.2

(was not the cas with older versions)

2: Put the zipped krc file where you want it to be run from

3: Unzip krc

4: IF YOU ARE NOT USING KRC WITH DAVINCI, IGNORE THIS STEP IF YOU ARE USING KRC WITH THE DAVINCI INTERFACE: Some default krc variables must be modified. open /krc/src/krccom.inc OR/AND krcc8m.f

Find the lines where MAXN1,MAXN2,MAXN3,MAXN4,MAXN5,MAXNH,KOMMON are defined and replace with:

PARAMETER (MAXN1 =1000)	   ! dimension of layers
PARAMETER (MAXN2 =86400)   ! dimension of times of day: 384=24*16
PARAMETER (MAXN3 =16)	   ! dimension of iteration days
PARAMETER (MAXN4 =37)	   ! dimension of latitudes
PARAMETER (MAXN5 =2161)	   ! dimension of saved seasons    #Uncomment it if necessary
PARAMETER (MAXNH =9600)	   ! dimension of saved times of day
PARAMETER (KOMMON=512000000) ! 4-byte words

Save and quit

5: Now go to /krc/src/cfiles and type:

make

Usually there are some minor-looking warnings; ignore them for now

6: Now go to /krc/src/ and type:

make

Sometimes, there are some minor-looking warnings; ignore them for now

7: Go back to /krc/src/cfiles and type:

make

There should be no warnings this time

8: Go back to /krc/src/ and type:

make

There should be no warnings this time. Screen should indicate " 'krc' is up to date "
