DarkRadiant - Compilation Guide

Compiling under Windows (MinGW)

This should hopefully cover the steps to prepare your machine to be able to compile the DarkRadiant Editor from source.

Needed Software

You'll need to download these pieces of software (these are all free, you don't need to pay for anything):

• TortoiseSVN for obtaining the sources
• MinGW the actual compiler
• ActivePython to run scons (other Python releases should work as well)
• scons to run the compilation scripts
• The GTK+ Framework (choose the latest stable version)
• GtkGLExt - OpenGL Extension to GTK+
• GLEW - OpenGL Extension Wrangler

Step 1: Install the Tools

First, download and install TortoiseSVN. Nothing special here, just install it into any folder of your preference. After installation it probably will ask to reboot your machine, as Tortoise integrates into the Explorer shell. (You can do that later, when all the other components have been installed).

Second, install the compiler MinGW. Launch the setup and choose the package Current, then be sure to check the box of the g++ compiler. Choose Download and Install in the next steps and let setup do the rest.

Third, install the ActivePython interpreter, which is needed to run the SconScript. Nothing spectacular here as well. After Python has been installed, run the scons installer (version 0.96.1 and 0.97 work for sure, don't know about others).

Fourth, install GTK+ plus GtkGLExt (be sure to remember where you installed the GtkGLExt package, we will need that path below.

Last, open the glew-1.x.y-win32.zip archive (version number masked by x.y) and copy the glew32.dll from the ZIP and paste it into your C:\Windows\system32 folder, so that the system can find it. Something similar is required for the GLExt binaries (libgdkglext-win32-1.0-0.dll and libgtkglext-win32-1.0-0.dll). You'll find them in the bin\ folders of the GtkGLExt folder. Copy the two DLLs into your C:\Windows\system32 folder so that they're found. Reboot the machine.

(Note: It's not mandatory to copy the DLLs into your system32 folder. You can also copy them into the folder containing the compiled darkradiant.exe, but we're not that far at this point, that's why I recommend copying it into your system32 directory.)

Set the Path to the MinGW Compiler

If scons complains about gcc and g++ missing, you will have to add the path to the compiler to your PATH environment variable:

• Press Win-Break or right-click on "My Computer" and choose "Properties". Go to advanced and seek the button for the Environment Variables. I'm not sure if it's called like this, because I'm running a German version of WinXP, but the Window should be something like this:

Look to the variable named "Path" in the lower part of the dialog and double click the property. A small window will pop-up containing the name and the value of the environment variable. You'll have to add the path to the MinGW\bin folder to the end of the long string:

;C:\MinGW\bin;

Be sure that a semicolon divides the newly added path from the previous ones, as I indicated above. A double semicolon won't hurt either, so if the above folder is matching to your installation, you can as well copy & paste it into that window. Close the dialogs by hitting OK, you're done with that. The next time you'll open a console the path should be functional. If not, please double-check your path for typos and/or post in the forums.

Step 2: Obtain the Sources

The complete codebase is available at SourceForge. To check out the sources, open up Explorer and create the folder you want to store them.

Right-click somewhere in the white space and choose SVN Checkout. A new dialog appears asing you for the repository URL and the checkout folder. You can copy and paste the URL from here into the dialog window:

https://darkradiant.svn.sourceforge.net/svnroot/darkradiant/trunk/darkradiant/

Click OK and prepare for a few minutes of downloading, the trunk repository is some ten megs large.

Step 3: Compile the Sources

If you're finished downloading the sources, open up the console by pressing Win-R or click Start > Run..., then type cmd and confirm. Once the DOS box is there, head to the according source folder by typing

cd C:\DarkRadiant

or whatever your path is where you downloaded them. Now type:

scons BUILD="release"

and the sources should start to compile (in release mode).

It's likely that I forgot something here and you might get scons complaining about a missing compiler or something. In that case, please tell greebo to update this tutorial accordingly.

The time neede to compile DarkRadiant strongly depends on your CPU power and may take up to ten minutes for a release build (a debug build may take much longer for whatever reasons).

Step 4: Run DarkRadiant

The readily compiled sources can be found in the install/ folder beneath the DarkRadiant root (the folder you downloaded your sources to).

C:\DarkRadiant\install\darkradiant.exe

Just create a shortcut by dragging the exe somewhere to your desktop with right mouse button and choose to create a link there. There is also an icon file located in the same folder you can use for this link to make it looking more pleasant.

If you get an error during startup, please contact greebo, perhaps there is something missing in this tutorial.

Compiling under Windows (VC++)

There is a prefabricated solution file (.sln) available in the tools/vcprojects folder. I created them using MS Visual C++ 2005 Express Edition, I can't say how older versions behave, but I suspect newer ones will work fine. Hit Ctrl-Shift-B in VC++ to start building the sources.

The project output files are setup so that the binaries get automatically installed in the install/, modules/ and plugins/ folders.

Note: As of October 2007, the graph_tree_model (GtkRadiant legacy) is not compatible with VC++'s STL implementation and has to be commented out (CompiledGraph.cpp).

See the previous section of how to checkout the sources.

svn co https://darkradiant.svn.sourceforge.net/svnroot/darkradiant/trunk/darkradiant/

Another note: This guide here is not yet complete, as I didn't start build the VC++ compile environment from scratch, but have the MinGW setup already running side-by-side. It's likely that the same run-time libraries (GTK, GTKGLExt, etc.) have to be installed as with the MinGW setup.

Compiling under Linux

Install Libraries and Tools

Ubuntu 7.04

You'll need a bunch of packages to get DarkRadiant to compile without glitches. I can't remember all from the top of my head, I will try to complete this list during my next Linux setup, but don't hold your breath. These are the names as found in Ubuntu 7.04 (Feisty Fawn):

• g++
• gcc-4.1
• scons 0.96.93 (or higher)
• libboost-dev
• libboost-serialization-dev
• libboost-filesystem-dev
• libboost-regex-dev
• libglew-dev
• libgtk2.0-dev
• libglib2.0-dev (maybe installed with libgtk2.0-dev)
• libgtkglext1-dev
• libxml2-dev
• libopenal-dev
• libalut-dev
• libvorbis-dev

Always download all the dependencies as well. Python should already be installed by Ubuntu at least, other distributions might require to install it separately.

If you get an error about the G++ compiler not being found, make sure you also install the g++ package, and not just the g++-4.1 package.

Ubuntu 7.10

• g++
• scons 0.97
• libboost-dev
• libboost-regex-dev
• libgtk2.0-dev
• libglew1.4-dev
• libgtkglext1-dev
• libxml2-dev
• libboost-serialization-dev
• libboost-filesystem-dev
• libboost-date-time-dev
• libalut-dev
• libvorbis-dev

Always download all the dependencies as well.

For the D3Hook plugin, the boost/asio library is needed (version 0.3.7, newer versions don't work). This library is located in the plugins/dm.d3hook/boost/ folder and should be ready for compilation.

Obtain the source

Install the subversion client. On Ubuntu this can be done via the Synaptic Manager or the command line:

sudo apt-get install subversion

Change to the directory where you want the source code to be in and then check the current version out of SVN with:

svn checkout https://darkradiant.svn.sourceforge.net/svnroot/darkradiant/trunk/darkradiant/ darkradiant

Compile

Change to the source directory and use scons to create a release build:

cd darkradiant
scons BUILD="release"

The compilation can take quite a few minutes, depending on your system.

If you use scons without arguments, a debugging build will be created, which can take even longer.

Next time you want to compile DarkRadiant, you can just type scons, the last build type is remembered by scons.

A fresh compile can be performed by clearing the compiled binaries first:

scons -c
scons BUILD="release"

If you want to update the source with the latest version from the SVN, just issue:

svn update

in the darkradiant source directory. svn info shows you what version you currently have.

Note for users with Multiprocessor Systems

Scons can run several jobs simultaneously, which can use your multicore system to its full capacity. By calling

scons JOBS="2"

the tool runs up to two compile tasks at the same time, which speeds up things a bit.

For a dual-core setup, a value of 2 jobs should be is sufficient, especially if you have only one Gbyte of memory, or less. If your machine has 2 or more Gbyte, you can also try higher values like:

scons JOBS="4"
