Compile code

If you downloaded the XBeach source code, you have to compile it in order to use the XBeach model. If you downloaded a pre-compiled version of XBeach, you can skip this entire step.

XBeach is written in Fortran and can be compiled on either a 32-bit Windows system or a UNIX system. XBeach is tested with two compilers on the following platforms:

• Windows XP 32-bit with the Intel Fortran compiler
• CentOS Linux (similar to Red Hat Linux) with the Intel Fortran or GFortran compiler

Other Windows and Linux platforms may not pose any problems, but it hasn't been tested officially yet. If you experience any problems on other Windows of Linux platforms, please describe the problem in the Compiling XBeach forum in the Forum page and we will try to help you out. Other compilers may pose problems and are not supported for now.

Use the Intel Fortran compiler

If you use the Intel Fortran compiler, the easiest way is to use this compiler from either the Visual Fortran or the Visual Studio 2008 (see figure) software development suites. You can open the corresponding project files in the trunk or the trunk/VS2008 directory and compile the entire project after selecting the right build (MPI, netCDF, debug, etc.)

Use the GFortran compiler

From the UNIX command line, go to the trunk directory of the XBeach source code location.

You can now compile XBeach by issuing the following commands:

>> ./configure
>> make

This command can be preceded by on of the following commands, to clear previously compiled parts of XBeach:

>> make clean
>> make distclean

Compiling XBeach using a specific compiler version is done by altering the first command a bit:

>> FC=gfortran44 ./configure

In order to compile XBeach with MPI support, the this command can again be altered slightly:

>> FC=gfortran44 ./configure --with-mpi

If this doesn't work you might need to specify a MPI compiler specifically by adding the MPIFC environment option (of course, the path may be different):

>> FC=gfortran44 MPIFC=/opt/mpich2-1.0.8-gcc44-x86_64/bin/mpif90 ./configure --with-mpi

The same can be done for done for netCDF support:

>> FC=gfortran44 ./configure --with-netcdf
>> FC=gfortran44 PKG_CONFIG_PATH=/opt/netcdf-4.1.1/gfortran/lib/pkgconfig ./configure --with-netcdf

Or both:

>> FC=gfortran44 ./configure --with-mpi --with-netcdf
>> FC=gfortran44 MPIFC=/opt/mpich2-1.0.8-gcc44-x86_64/bin/mpif90 PKG_CONFIG_PATH=/opt/netcdf-4.1.1/gfortran/lib/pkgconfig ./configure --with-mpi --with-netcdf

If you use the Intel Fortran compiler on a UNIX system, you might need to initialize the compiler by the following command:

>> . /opt/intel/Compiler/11.0/081/bin/ifortvars.sh ia32

If you use MPI support, please make sure that the MPI software is added to your path:

>> export PATH="/opt/mpich2/bin:${PATH}"

The GFortran compiler and the XBeach library

Nowadays, XBeach can be compiled as library. In fact, XBeach is always compiled as library, possibly with a wrapper binary calling this library. See the following examples on how to deal with this new program structure and the GFortran compiler.

# this will put xbeach in the /home/user/xbeach-r1234/bin directory
./configure --prefix=/home/user/xbeach-r1234 && make install

# this will put xbeach shell script +  .libs directory in the current directory
./configure & make

# this will create an xbeach wrapper script and .libs directory for multiple versions
mkdir r1234
mkdir r1235
svn up -r1234
cd r1234
../configure
make
cd ../r1235
../configure
make

# this will make xbeach versions in multiple directories
mkdir ~/xbeachr1234
mkdir ~/xbeachr1235
svn up -r1234
./configure --prefix=$(cd;pwd)/xbeachr1234
make install
make clean
svn up -r1235
./configure --prefix=$(cd;pwd)/xbeachr1235
make install

# this debugs xbeach
./libtool --mode=execute gdb ./xbeach

# this shows what xbeach is linked against
./libtool --mode=execute ldd ./xbeach # otool -L in OSX

# this debugs xbeach in mpi in 2 different terminals
mpirun -np 2 xterm -e ./libtool --mode=execute gdb ./xbeach

All paths in the examples above might need to be altered to fit the local environment.
