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

Recently, it appears that XCode has come with all the necessary libraries and compiler.

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.

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

2: Copy 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, GO TO 5

Double check that some default krc variables have been modified to run with the Davinci Interface

open /krc/src/krccom.inc OR/AND krcc8m.f

Replace the first 37 lines with:

Save and quit

5: Compile KRC (and PORB)

Copy these lines:

cd src/cfiles/
make

cd ..
make

cd ./cfiles
make

cd ..
make

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

cd ../run
rm krc
rm porbmn

ln -s ../src/krc
ln -s ../src/porbmn

mkdir out/

6: Input File Modification

Generally, it is a good idea to assign no layering by default. To do this, open /master.inp and set IC2 to 999
