Introduction

After completing these installation instructions, you will have an IDE for GRASS that will allow you to perform that following development tasks:

Workbench

  • Switch between C/C++, Python, Debug and SVN perspectives

Browsing

  • Navigate the GRASS source code trunk
  • Edit source code
  • Select a symbol and go to to its declaration

Building

  • Build the entire GRASS system
  • Build an individual GRASS module

Running

  • Run GRASS modules and Python scripts

Debugging

  • Set breakpoints
  • Single step through source code
  • View variables and memory values

Versioning

  • Commit source code to the SVN repository
  • Update source code from the SVN repository

Install TortoiseSVN

Download and install from the TortoiseSVN Website.

During installation, include the "entire command line tools" so that "svn up" can be run from a Windows Command Prompt or MSYS shell.

The following path should have been added to PATH: 

C:\Program Files\TortoiseSVN\bin

From Command Prompt, enter the following command: 

>where svn

To run "svn up" from a Command Prompt, enter the following commands: 

>cd C:\OSGeo4W\src\grass7_trunk
>svn up

To run "svn up" from a MSYS shell, enter the following commands: 

$ export PATH=$PATH:/c/"Program Files"/TortoiseSVN/bin
$ cd /c/OSGeo4W/src/grass7_trunk
$ svn up

Install OSGeo4W Runtime and Development Framework

Download and install the 32bit version from the OSGeo4W Website.

It will be installed in this directory: 

C:\OSGeo4W

Checkout GRASS Source Code and Make Debug Build

Checkout the GRASS development branch using the SVN command from the GRASS Download Website.

Open a MSYS shell. 

$ cd /c/OSGeo4W/src
$ export PATH=$PATH:/c/"Program Files"/TortoiseSVN/bin
$ which svn
$ svn checkout https://svn.osgeo.org/grass/grass/trunk grass7_trunk

Run a 'debug' build. 

$ cd /c/OSGeo4W/src/grass7_trunk
$ export CFLAGS='-g -Wall'
$ ./mswindows/osgeo4w/package.sh

This will take some time to complete.

Build activity is logged to this file: 

C:\OSGeo4W\src\grass7_trunk\mswindows\osgeo4w\package.log

Install Doxygen and Make Documentation

Install latest Doxygen binary distribution for Windows.
Download and install from the | Doxygen Website.

Install latest Graphviz binary distribution for windows.
Download and install from the | Graphviz Website.

Install latest basic TeX/LaTeX system for Windows.
Download and install from the | MikTeX Website.

After the TeX/LaTeX system is installed, and during the first time "make pdfdocs" is run, expect to be prompted for additional packages that must be installed to complete the TeX/LaTex system.

Open a MSYS shell. 

$ export PATH=$PATH:/c/"Program Files"/doxygen/bin
$ export PATH=$PATH:/c/graphviz-2.38/release/bin
$ export PATH=$PATH:/c/"Program Files (x86)"/"MiKTeX 2.9"/miktex/bin
$ echo $PATH
$ cd /c/OSGeo4W/src/grass7_trunk/
$ make htmldocs
$ make pdfdocs

Open the HTML formatted documentation using a web browser: 

file:///C:/OSGeo4W/src/grass7_trunk/html/index.html
