Mac instructions

Revision as of 21:15, 8 January 2019

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:

C_Titl  krcc8m.f = KRCCOM common for input and transfer variables

Save and quit

5: Compile KRC 1/3

Go to /krc/src/cfiles and type:

make

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

6: Compile KRC 2/3

Go to /krc/src/ and type:

make

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

7: Compile KRC 3/3

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

make

There should be no warnings this time

8: Check

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

make

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