INTRODUCTION

Enemy Territory: Legacy is based on the raedwulf-etproject which in turn is based on the GPL'd source code of Wolfenstein: Enemy Territory.

The main goals of the project are fixing bugs, cleaning up the codebase and adding useful featureswhile remaining compatible with the ET 2.60b version.

The Legacy mod is the default mod shipped with ET: Legacy. It aims to add many useful features andimprovements, while staying close to the original gameplay, as well as being lightweight and extensiblethrough Lua scripts.

For more information consult our changelog.

ET: Legacy development is a collaborative effort done in an open, transparent and friendly manner.Anyone is welcome to join our efforts!

GENERAL NOTES

Game data

Wolfenstein: Enemy Territory is a free release, and can be downloaded from Splash Damage.

This source release contains only the engine and mod code but not any game data,which is still covered by the original EULA and must be obeyed as usual.

In order to run ET: Legacy you will need to copy the original assets files(pak0.pk3, pak1.pk3 and pak2.pk3) to the etmain folder.

Compatibility with Enemy Territory 2.60b

ET: Legacy remains compatible with the ET 2.60b version as much as possible.

Please note that ET: Legacy is not compatible with PunkBuster enabled servers.ET: Legacy clients also cannot connect to servers running the ETPro mod.

Linux 64 bit

Please remember that 64 bit ET: Legacy clients can only connect to servers runningmods providing a 64 bit version. You will be able to play 32 bit-only mods only ifyou compile ET: Legacy on a 32 bit system or cross-compile it for 32 bit architectureon a 64 bit system.

At the moment, only the Legacy mod is available in 64 bit version, while all otherexisting mods are available in 32 bit only version.

In case you are a running a 64 bit system, you probably might want to use thebundled libraries which are located in a separate etlegacy-libs repository andcan be automatically downloaded using the git submodule command. See the nextsection for more details.

DEPENDENCIES

• CMake (compile-time only)
• OpenGL
• GLEW
• SDL
• ZLib
• MiniZip
• libjpeg-turbo or libjpeg
• libcurl (optional, enabled by default)
• Lua (optional, enabled by default)
• Ogg Vorbis (optional, enabled by default)
• Theora (optional, enabled by default)
• Freetype (optional, enabled by default)
• libpng (optional, enabled by default)
• SQLite (optional, enabled by default)
• OpenAL (optional, enabled by default)

Grab info about current lib versions from our wiki page ET: Legacy Libs_Changelog

To get the latest source code install git andclone our repository hosted at Github.com:

$ git clone git://github.com/etlegacy/etlegacy.git

If the required dependencies are not installed on your system run:

$ git submodule init
$ git submodule update

This downloads the essential dependencies into the libs/directory. You can choosewhether to use bundled libraries instead of the system ones by changing theBUNDLED_LIBS variable in the CMakeList.txt configuration file. You can then selectwhich bundled libraries to use by toggling the respective BUNDLED_XXX variable.

COMPILE AND INSTALL

To install the binaries system-wide, you need to compile ET: Legacy with hardcodedfs_basepath.

The following variables can be adjusted in CMake:

• INSTALL_DEFAULT_BASEDIR: sets default fs_basepath, i.e. where etl and etldedexecutables look for data files. In most cases it is CMAKE_INSTALL_PREFIX+INSTALL_DEFAULT_MODDIR.Defaults to empty value, because we want fs_basepath to be the current working directorywhen not installing the game system-wide.

• (optional) INSTALL_DEFAULT_BINDIR: Location for executables. Appended to CMAKE_INSTALL_PREFIX.Defaults to "bin".

• (optional) INSTALL_DEFAULT_MODDIR: Location for libraries and paks. Appended toCMAKE_INSTALL_PREFIX. Defaults to "share/etlegacy" and then "legacy" is appended to it.

Linux

Install required dependencies.

• option A: easybuild

In terminal, run:

$ ./easybuild.sh

ET: Legacy will be installed in ~/etlegacy.

• option B: command line

In terminal, run:

$ mkdir build && cd build && cmake ..

To compile, run:

$ make

If you wish to install ET: Legacy system-wide, run:

# make install

Be sure to set the CMake variables (see above) beforehand.

NOTES:

• Even if you have a 64 bit linux distribution which provides 32 bit versions of allthe required libraries, you might also need the development libraries (-devel packages)installed on your system.

• In order to compile the jpeg-turbo library properly you will need the nasm assembler.

Crosscompiling on Linux with MinGW-w64

In terminal, run:

$ mkdir build && cd build
$ cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchain-cross-mingw-linux.cmake ..
$ make

By default, MinGW name is set to i686-w64-mingw32. You may have to change it incmake/Toolchain-cross-mingw-linux.cmake depending on how it is called on your system.

Windows

Install:

1. Visual Studio Community with the Desktop Development with C++ workload
2. CMake and make sure it is added to your system PATH

• option A: easybuild

  1. run easybuild.bat

ET: Legacy will be installed in My Documents\ETLegacy-Build.

• option B: Visual Studio

  1. create a build directory inside the directory which contains ET: Legacy sources
  2. open Visual Studio Command Prompt in the Start menu
  3. change directory with cd to the newly created build directory

In the command prompt, run:

cmake -G "NMake Makefiles" -DBUNDLED_LIBS=YES .. && nmake

or

cmake -G "Visual Studio 16" -DBUNDLED_LIBS=YES ..

and open the resulting project in Visual Studio.

NOTES:

• If compilation of bundled libraries is aborted for any reason, you will probably need to clean thelibs directory and start over. This can be done by executing git clean -df && git reset --hard HEADinside libs/ directory.

• If the build fails during libcurl compilation because of missing sed utility, download it fromGnuWin and place it into your system path orcopy it into MSVC/VC/bin. It also comes with Git and can be placed into your system pathautomatically if you select that option during Git installation.

Mac OS X

Install:

1. [Xcode](https://developer.apple.com/xcode/downloads/)
2. [Homebrew](http://brew.sh/)
3. [Homebrew Cask](http://caskroom.io/)

Then brew the following packages in the terminal app:

$ brew cask install xquartz
$ brew install --universal gnu-sed cmake glew sdl2 minizip jpeg-turbo curl lua libogg libvorbis theora freetype sqlite openal-soft

The --universal flag ensures both 32bit and 64bit libraries are installed. Although your system curl library supports both architectures, you also need to install its headers.

• option A: easybuild

In Terminal, run:

$ ./easybuild.sh

This will put an 'etlegacy' folder into your user folder.

• option B: command line

In terminal, run:

$ mkdir build && cd build && cmake ..

To compile, run:

$ make

If you wish to install ET: Legacy system-wide, run:

# make install

Be sure to set the CMake variables (see above) beforehand.

NOTES:

• In the legacy mod folder, the cgame_mac and ui_mac files are redundant since they are in theetl_bin.pk3 and will be extracted at runtime, so you can delete those. The client is named etl.app(and can safely be renamed), while the dedicated server is just a command-line binary named "etlded".
