#!/bin/bash # --------------------------------------------------------------------------- # # comp : Compiler script for use in ad3 (customized for hardware and # # optimization). Note that this script will not be replaced if part # # of WAVEWATCH III is re-installed. Used by ad3. # # # # use : comp name # # name: name of source code file without the extension. # # # # error codes : 1 : input error # # 2 : no environment file $ww3_env found. # # 3 : error in creating scratch directory. # # 4 : w3adc error. # # 5 : compiler error. # # # # remarks : # # # # - This script runs from the scratch directory, where it should remain. # # # # - For this script to interact with ad3, it needs to generate / leave # # following files : # # $name.f90 : Source code (generated by ad3). # # $name.o : Object module. # # $name.l : Listing file. # # comp.stat.$name : status file of compiler, containing number of errors # # and number of warnings (generated by comp). # # # # - Upon (first) installation of WAVEWATCH III the user needs to check the # # following parts of this script : # # sec. 2.b : Provide correct compiler/options. # # sec. 3.a : Provide correct error capturing. # # sec. 3.d : Remove unnecessary files. # # # # - This version is made for the Intel ifort version 8.1 on a Pentium 4 # # processor. # # # # Hendrik L.
