DiffEngine Development Environment Setup

Currently Diffengine is being developed under Windows XP, Eclipse and GNU Tools. All software needed for development except Windows is open-source.

Software

Other versions may work too, but the process was checked with these.

Java(TM) SE Runtime Environment 6 (12,6 MB) (http://java.sun.com/javase/downloads/index.jsp)
Eclipse SDK 3.2.1, Windows (120,8 MB) (http://www.eclipse.org/downloads)
CDT 3.1.1 Runtime Feature (C/C++ Development Tools For Eclipse 11,6 MB) (http://download.eclipse.org/tools/cdt/releases/callisto/dist/3.1.1)
Cygwin (34,5 MB) (http://www.cygwin.com) Install using setup.exe with following packages: gcc-core, gcc-g++, gdb, make. Of course install all dependencies too.
Subversion 1.4.3 for Win32 (5,0 MB) (http://subversion.tigris.org/project_packages.html)
Subclipse plug-in for Eclipse (15,1 MB) (http://subclipse.tigris.org/install.html) Install through Help -> Software Updates following directions from home page.

Directory settings

These paths will be created in system. Some of them will be created by software installation, others need to be created manually.

<JAVA_DIR> e.g. C:\Program Files\Java\jre1.6.0, directory with JRE installation
<WINSYS_DIR> e.g. C:\WINDOWS\system32, system directory
<CYGWIN_DIR> e.g. C:\cygwin, directory with cygwin installation
<SVN_DIR> e.g. C:\svn, directory with subversion installation
<ECLIPSE_DIR> e.g. D:\eclipse, directory with eclipse installation
<WORKSPACE_DIR> e.g. D:\workspace, directory with working version of source code. We'll also set this as Workspace in Eclipse.
<SVNDB_DIR> e.g. D:\svndb, directory for subversion repository

We have to add following paths to PATH environment variable (using My Computer > Properties > Advanced > Environment variables)

<CYGWIN_DIR>\bin
<SVN_DIR>\bin

If PATH variable doesn't contain <WINSYS_DIR>, we add it too.

Creating Subversion Repository

Copy diffengine.dump file into <SVNDB_DIR>
Enter directory <SVNDB_DIR>

Enter following commands

svnadmin create diffengine

      svnadmin load diffengine < diffengine.dump

This will create and load subversion repository diffengine.

Now we have to create windows service, so that other tools can access the repository

sc create svnserve binpath= "<SVN_DIR>\bin\svnserve.exe 
      --service --root <SVNDB_DIR>" displayname= "Subversion Repository" 
      depend= Tcpip

Then we start it and optionally we can set it to start automatically on Windows start-up

sc start svnserve sc config svnserve start= auto

Creating Eclipse Project

In Eclipse, open perspective 'SVN Repository Exploring ' (Window > Open Perspective > Other... > SVN Repository Exploring) and add new repository location

svn://localhost/diffengine

Check-out trunk as new project (Check out as a project configured using the New Project Wizard), name it 'diffengine' and make it a 'Managed Make C Project'.

New directory '<WORKSPACE_DIR>\diffengine' will be created.

Create new subdirectory '<WORKSPACE_DIR>\diffengine\output' . It is used for debugging output.

Unpack testdata.zip into '<WORKSPACE_DIR>\diffengine' which creates '<WORKSPACE_DIR>\diffengine\testdata' folder.

Eclipse Settings

Settings in Window > Preferences:

General > Workspace > Build automatically - leave unchecked
