GENIE WindowsCompilation

Building GENIE on Windows Platforms

The GENIE makefiles have been modified to enable a command line compilation of the framework under Windows using Linux emulation software.

Prerequisites

The build system is known to work with the following software:

Tool		Software	Versions	Notes
Linux emulation		CygWin	1.5.12-1
		MinGW (MSYS)	1.0.10	Build only. There is no bash shell available so genie_example.job cannot be executed.
Third party libraries		NetCDF	3.5.0, 3.6.0, 3.6.1, 3.6.2	Pre-built dll from UCAR can be used with the native microsoft compilers. We recommend building the NetCDF library locally.
		Python	2.3.3+	Available in CygWin. Must be installed separately for MinGW.
Native Microsoft	Fortran Compiler	Compaq Visual Fortran	6.6C
		Intel Visual Fortran	9.1, 10.0, 10.1
	C/C++ Compiler / Linker	Microsoft Visual Studio .NET 2003	7.1.3088
		Microsoft Platform SDK for Server 2003	R2
		Microsoft Visual Studio 2005	8.0.50727.762
GNU Compilers	Fortran Compiler	GNU g95	0.91
	C/C++ Compiler / Linker	GNU gcc	4.0.3
		GNU ld	2.16.91

Installing a Linux Emulator

In order to execute the GENIE build process on a Windows platform it is necessary to install a Linux emulator that can process the GNU make files. There are two popular Linux emulation tools for Windows; Cygwin and MinGW. Cygwin provides a comprehensive Linux emulation layer for Windows and can be used to build, execute and manage GENIE. MinGW (Minimalist GNU for Windows) provides a limited set of tools that are sufficient to build GENIE but cannot be used to configure the model for execution. We therefore recommend the Cygwin route but provide details of MinGW for completeness.

Cygwin installation

Download the Cygwin setup executable from the Cygwin website at http://cygwin.com/. Execute the setup program and install Cygwin as directed. When asked to select packages please ensure that the following packages are installed:

• Base -> bash
• Devel -> make
• Interpreters -> python
• Interpreters -> perl (for documentation)

Download g95-x86-cygwin.tgz from ftp.g95.org. Copy this file to the root of your cygwin distribution. In cygwin:

 cd /
 tar zxvf g95-x86-cygwin.tgz

MinGW installation

MinGW http://www.mingw.org/ provides a build environment capable to generating Windows executables that do not rely on 3rd party dlls.

Building NetCDF

Download NetCDF source release from UCAR:

 http://www.unidata.ucar.edu/downloads/netcdf

Extract the contents of the archive to a convenient location <netcdf_root>.

GNU Compilers

In a Cygwin environment that has g95 installed, navigate to the NetCDF directory (here <netcdf_root_cygpath> refers to the location of the NetCDF root in the Cygwin path style. e.g. /cygdrive/c/netcdf-3.6.2).

 cd <netcdf_root_cygpath>
 F90=g95 ./configure --prefix=<netcdf_root_cygpath>
 make check
 make install
