Windows Prerequisites

Install the Java Development Kit

GeoFIS build needs the Java Development Kit (JDK) to be installed (version 1.8 or greater). Note that the Java Runtime Environment (JRE) is not sufficient, you will need the JDK.
To check if you have the JDK installed, type this on the Windows terminal (Winkey + R then type cmd):

javac -version

If you do not have the JDK installed, download and install the Java SE JDK (SE = Standard Edition).

Setting the JAVA_HOME

set JAVA_HOME system environment variable to the location of your JDK, e.g. C:\Program Files\Java\jdk1.8.0_80

Install Apache Maven

Download the latest Maven binary zip archive and follow Installation Instructions.

Install SWIG

Download the latest swigwin Windows prebuilt executable and unzip to the directory you wish to install SWIG.
Add the unpacked ‘bin’ directory to Windows System Path.
Open a new Windows command-line and run swig -version to verify that it is correctly installed.

Install TortoiseSVN Subversion client

Download and install from http://tortoisesvn.net/downloads.html

Install MinGW C++ Compiler

There are several ports of GCC on Windows:

Download and extract the gcc archive from WinLibs standalone build of GCC and MinGW-w64 for Windows.
Or download mingw-w64-install.exe from http://mingw-w64.sourceforge.net.
- Install it in ‘C:mingw-w64’ destination folder. No spaces in installation path.
- Select ‘i686’ or ‘x86_64’ architecture, depending of your java JRE architecture (32 or 64 bits).
Or download and unzip from Toolchains targetting Win32 or Toolchains targetting Win64 (gcc version <= 8.1.0)
Or install gcc from tdm-gcc.
