• Step 1: Install a 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 are required for version 2.3.2 (was not the case with older versions)

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

• Step 3: Unzip krc

• Step 4:

IF YOU ARE NOT USING KRC WITH DAVINCI, IGNORE THIS STEP, GO TO Step 5

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

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

make

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

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

make

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

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

make

There should be no warnings this time

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

make

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

• Step 9: in Makefile, a few modifications may be necessary:

REPLACE: HHKLIB=/mars/u/krios/krc/builds/3.2.1/ # top of libraries to use WITH: HHKLIB=~/Applications/krc03_02_01b/krc_3.2.1.r12877/ #SP 03/25/2015

REPLACE: b2b.o: /mars/u/krios/krc/builds/3.2.1/src/b2b.f WITH: b2b.o: ~/Applications/krc03_02_01/krc_3.2.1.r12877/src/b2b.f #SP 03/25/2015

REPLACE: catime.o: /mars/u/krios/krc/builds/3.2.1/src/catime.f WITH: catime.o: ~/Applications/krc03_02_01/krc_3.2.1.r12877/src/catime.f

REPLACE: white1.o: /mars/u/krios/krc/builds/3.2.1/src/white1.f WITH: white1.o: ~/Applications/krc03_02_01/krc_3.2.1.r12877/src/white1.f
