Compilatore gcc e gfortran: differenze tra le versioni

Versione delle 10:59, 10 mar 2017

How to install Delft3D with gfortran

1) Install all pre-requisites required (read Delft3D website)

2) compile mpich

./configure --prefix=/opt/mpich_gfor/ --enable-shared --enable-sharedlibs=gcc --enable-lib-depend F77=gfortran FC=gfortran CC=gcc CXX=g++ FCFLAGS=-fPIC CFLAGS=-fPIC CCFLAGS=-fPIC CXXFLAGS=-fPIC 2>&1 | tee c.txt make 2>&1 | tee m.txt make install 2>&1 | tee mi.txt

3) compile hdf5

LDFLAGS="-L/opt/mpich_gfor/lib64 -L/usr/local/lib" CPPFLAGS="-I/opt/mpich_gfor/include -I/usr/local/include" ./configure --prefix=/opt/hdf5_gfor --enable-shared --enable-hl --enable-fortran --enable-parallel

make make check make install

update PATH update LD_LIBRARY_PATH

4) compile netcdf

LDFLAGS="-L/opt/mpich_gfor/lib64 -L/opt/hdf5_gfor/lib64 -L/usr/local/lib" CPPFLAGS="-I/opt/mpich_gfor/include -I/opt/hdf5_gfor/include/ -I/usr/local/include" ./configure --enable-netcdf-4 --enable-dap --enable-shared --prefix=/opt/netcdf_4411_gfor

make make check make install

update PATH update LD_LIBRARY_PATH

5) compile netcdf fortran

LDFLAGS="-L/opt/mpich_gfor/lib64 -L/opt/hdf5_gfor/lib64 -L/usr/local/lib -L/opt/netcdf_4411_gfor/lib64" CPPFLAGS="-I/opt/mpich_gfor/include -I/opt/hdf5_gfor/include/ -I/usr/local/include -I/opt/netcdf_4411_gfor/include" ./configure --enable-shared --prefix=/opt/netcdf_444_fortran_gfor/

make make check make install

update PATH update LD_LIBRARY_PATH

6) compile Delft3D:

./build.sh .-gnu

This is my build.sh:

1. ! /bin/bash

1. -------------------------------------------------------------------------------
2. Top-Level Build Script for Delft3D Open Source Code
4. There are command-line options to select Fortran compiler and debug or not.
6. ToDo: Remove stripping of executables when the debug flag is set.
7. It's even debatable whether stripping belongs in the build. I think not.
9. ToDo: Don't preintialize the compiler, the user should do this himself
10. so that he's aware exactly which version he's using. Besides, we can't
11. keep up with every new compiler update. This script should be ultra-low
12. maintanence.

1. This script must be executed in the directory where it resides

orgdir=`pwd` scriptdirname=`readlink \-f \$0` maindir=`dirname $scriptdirname` cd $maindir

1. Default values

compiler= configureArgs= debug=0 noMake=0 platform='ia32' useSp=0

1. -------------------------------------------------------------------------------

function usage {

   echo "Usage: `basename $0` <compiler> [-debug] [-make] [-64bit] [-sp] [-configure <args>] [-?]"
   echo "Compiler is one of:"
   echo "    -gnu"

   echo "    -intel12"
   echo "    -intel14 (-intel14.0.3)"
   }

1. -------------------------------------------------------------------------------
2. Add date time to logging info

function log {

   echo "`date +%Y%m%d.%H%M%S` :: $*"
   }

1. -------------------------------------------------------------------------------
2. Add a directory to an environment parameter

function addpath {

   path="$1"
   shift

   for dir in $*; do
       if [ -d $dir ]; then
           eval "export $path=\"$dir:\$$path\""
       fi
   done
   }

1. -------------------------------------------------------------------------------
2. Identify which program is used

function witch {

   w=`which $1`
   (
       cd `dirname $w`
       /bin/pwd
   )
   }

1. ===============================================================================

1. fPIC is the result of the mixing of static and libtool libraries.
2. If you want to avoid this you can use convenience libraries.
3. Don't do this for non AMD64 because it will lead to worse performance.
