ET: Legacy is an open source project based on the code of Wolfenstein: Enemy Territory which was released in 2010 under the terms of the GPLv3.
There are two aspects to this project:
- An updated game engine, ET: Legacy, which aims to fix bugs and security exploits, remove old dependencies, add useful features and modernize its graphics while still remaining compatible with ET 2.60b and as many of its mods as possible.
- A new mod, Legacy, which aims to add many useful features and improvements while staying close to the original gameplay, as well as being lightweight and extensible through Lua scripts.
For more information consult our wiki.
See CONTRIBUTING.
See SECURITY.
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 pak0.pk3 assets file to the etmain folder. In addition, third party mods might also require the pak1.pk3 and pak2.pk3 assets files.
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.
Please remember that 64 bit ET: Legacy clients can only connect to servers running mods providing a 64 bit version. You will be able to play 32 bit-only mods only if you compile ET: Legacy on a 32 bit system or cross-compile it for 32 bit architecture on a 64 bit system.
At the moment, only the ETrun, ETJump, N!tmod and Legacy mods are available in 64 bit version, while all other existing mods are available in 32 bit only version. Read more on the Compatible mods wiki page.
In case you are a running a 64 bit system, you probably might want to use the
bundled libraries which are located in a separate etlegacy-libs repository and
can be automatically downloaded using the git submodule command. See the next
section for more details.
Required:
- CMake (compile-time only)
- OpenGL
- GLEW
- SDL
- ZLib
- MiniZip
- libjpeg-turbo or libjpeg
Optional, enabled by default:
- libcurl
- WolfSSL or OpenSSL
- Lua
- Ogg Vorbis
- Theora
- Freetype
- libpng
- SQLite
- OpenAL
Grab info about current lib versions from our Libs Changelog wiki page.
To get the latest source code install git and clone our repository hosted at Github.com:
$ git clone [email protected]:etlegacy/etlegacy.gitIf the required dependencies are not installed on your system run:
$ git submodule init
$ git submodule updateThis downloads the essential dependencies into the libs/directory. You can choose
whether to use bundled libraries instead of the system ones by changing the
BUNDLED_LIBS variable in the CMakeList.txt configuration file. You can then select
which bundled libraries to use by toggling the respective BUNDLED_XXX variable.
To install the binaries system-wide, you need to compile ET: Legacy with hardcoded
fs_basepath.
The following variables can be adjusted in CMake:
-
INSTALL_DEFAULT_BASEDIR: sets defaultfs_basepath, i.e. where etl and etlded executables look for data files. In most cases it isCMAKE_INSTALL_PREFIX+INSTALL_DEFAULT_MODDIR. Defaults to empty value, because we wantfs_basepathto be the current working directory when not installing the game system-wide. -
(optional)
INSTALL_DEFAULT_BINDIR: Location for executables. Appended toCMAKE_INSTALL_PREFIX. Defaults tobin. -
(optional)
INSTALL_DEFAULT_SHAREDIR: Location for shared data. Appended toCMAKE_INSTALL_PREFIX. Defaults toshare. -
(optional)
INSTALL_DEFAULT_MODDIR: Location for libraries and paks. Appended toCMAKE_INSTALL_PREFIX. Defaults tolib/etlegacyand thenlegacyis appended to it. -
(optional)
DOCDIR: Location for documentation. Defaults toINSTALL_DEFAULT_SHAREDIR/doc/etlegacy.
Install required dependencies.
- option A: easybuild
In terminal, run one of the following:
$ ./easybuild.sh # for compiling a 32 bit version or
$ ./easybuild.sh -64 # for compiling a 64 bit versionET: Legacy will be installed in ~/etlegacy.
- option B: command line
In terminal, run:
$ mkdir build && cd build && cmake ..To compile, run:
$ makeIf you wish to install ET: Legacy system-wide, run:
$ make installBe 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 all the 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.
-
On some systems, CMake might have trouble locating 32-bit libraries and tries to use 64-bit ones when building 32-bit. This can be fixed by setting the following enviromental variables before running CMake (note: running easybuild takes care of this for you)
$ export CC="gcc -m32"
$ export CXX="g++ -m32"
# or simply run cmake with
$ CC="gcc -m32" CXX="g++ -m32" cmake ..In terminal, run:
$ mkdir build && cd build
$ cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchain-cross-mingw-linux.cmake ..
$ makeBy default, MinGW name is set to i686-w64-mingw32. You may have to change it in
cmake/Toolchain-cross-mingw-linux.cmake depending on how it is called on your system.
Install:
- Visual Studio Community with the Desktop Development with C++ workload
- CMake and make sure it is added to your system PATH
-
option A: easybuild
- run easybuild.bat
ET: Legacy will be installed in My Documents\ETLegacy-Build.
-
option B: Visual Studio
- create a
builddirectory inside the directory which contains ET: Legacy sources - open Visual Studio Command Prompt in the Start menu
- change directory with
cdto the newly created build directory
- create a
In the command prompt, run:
$ cmake -G "NMake Makefiles" -DBUNDLED_LIBS=YES .. && nmakeor
$ cmake -G "Visual Studio 16" -A Win32 -DBUNDLED_LIBS=YES .. # Visual Studio 2019
# or "Visual Studio 17" for Visual Studio 2022and open the resulting project in Visual Studio.
NOTES:
-
If compilation of bundled libraries is aborted for any reason, you will probably need to clean the libs directory and start over. This can be done by executing
git clean -df && git reset --hard HEADinsidelibs/directory. -
If the build fails during libcurl compilation because of missing sed utility, download it from GnuWin and place it into your system path or copy it into
MSVC/VC/bin. It also comes with Git and can be placed into your system path automatically if you select that option during Git installation.
Install:
- Xcode:
- At least a recent Version of Xcode Command Line Tools (Terminal ->
xcode-select --install) - or a complete Xcode IDE (through App Store or https://developer.apple.com/xcode/downloads/)
- Homebrew (https://brew.sh/)
Then brew the following packages in the terminal app:
# all compilation tools needed
$ brew install cmake autoconf nasm automake libtool
# Libraries if you do not wish to compile and use the provided sources (BUNDLED_LIBS)
$ brew install glew sdl2 minizip jpeg-turbo curl lua libogg libvorbis theora freetype libpng sqlite openal-softAlternative way to install the dependencies is to run
$ brew bundle
$ brew bundle --file=misc/macos/libs.BrewfileDepending on what brew version you're using (mostly older ones), you have to specify brew install --universal to get both 32bit and 64bit libs. If it throws an error, just use the command listed above. Although your system curl library supports both architectures, you also need to install its headers.
- option A: easybuild
There are many flags and options provided by easybuild.sh. The ET: Legacy version you can compile depends on the used macOS version.
If you're running up to macOS 10.14 (Mojave), use one the following flags in Terminal.app:
$ ./easybuild.sh # for compiling a 32 bit version or
$ ./easybuild.sh -64 # for compiling a 64 bit versionThis will put an 'etlegacy' folder with the selected arch into your user folder.
With macOS 10.15 (Catalina) and above, your only option is to compile and run a 64 bit client. Therefore you need to use the following flags:
$ ./easybuild.sh -64 --osx=10.15 #watch out for the double dash at --osx !Take a look into easybuild.sh for more information and further options/flags.
- option B: command line
In terminal, run:
$ mkdir build && cd build && cmake ..Look into easybuild.sh for all available CMake options.
To compile, run:
$ makeIf you wish to install ET: Legacy system-wide, run:
$ make installBe 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 the mod .pk3 and will be extracted at runtime, so you can delete those. The client is named "ET Legacy.app" (and can safely be renamed), while the dedicated server is just a command-line binary named "etlded".
ET: Legacy supports both OpenGL and OpenGL ES.
