Half-Life SDK for GoldSource and Xash3D Build Status Windows Build Status

Half-Life SDK for GoldSource & Xash3D with some bugfixes.

Obtaining source code

Either clone the repository via git or just download ZIP via Code button on github. The first option is more preferable as it also allows you to search through the repo history, switch between branches and clone the vgui submodule.

To clone the repository with git type in Git Bash (on Windows) or in terminal (on Unix-like operating systems):

git clone --recursive https://github.com/FWGS/hlsdk-xash3d

Build Instructions

Windows. Using Developer Command Propmt for Visual Studio

Prerequisites

Install and run Visual Studio Installer. The installer allows you to choose specific components. Select Desktop development with C++. You can untick everything you don't need in Installation details, but you must keep MSVC and C++ CMake tools for Windows ticked.

Building

Run Developer command prompt for VS via Windows Start menu. Inside the prompt navigate to the hlsdk directory, using cd command, e.g.

cd C:\Users\username\projects\hlsdk-xash3d

Note: if hlsdk-xash3d is unpacked on another disk, nagivate there first:

D:
cd projects\hlsdk-xash3d

Сonfigure the project:

cmake -A Win32 -B build -DCMAKE_INSTALL_PREFIX="dist"

Once you configure the project you don't need to call cmake anymore unless you modify CMakeLists.txt files or want to reconfigure the project with different parameters.

The next step is to compile the libraries:

msbuild -verbosity:normal /property:Configuration=Release build/INSTALL.vcxproj

hl.dll and client.dll will appear in the directory configured via CMAKE_INSTALL_PREFIX option (dist in this example).

If you have a mod and want to automatically install libraries to the mod directory, set GAMEDIR variable to the directory name and CMAKE_INSTALL_PREFIX to your Half-Life or Xash3D installation path:

cmake -A Win32 -B build -DGAMEDIR=mod -DCMAKE_INSTALL_PREFIX="C:\Program Files (x86)\Steam\steamapps\common\Half-Life"

Then call msbuild as described above.

Choosing Visual Studio version

You can explicitly choose a Visual Studio version on the configuration step by specifying cmake generator:

cmake -G "Visual Studio 16 2019" -A Win32 -B build -DCMAKE_INSTALL_PREFIX="dist"

Editing code in Visual Studio

After the configuration step, HLSDK-XASH3D.sln should appear in the build directory. You can open this solution in Visual Studio and continue developing there.

Windows. Using Microsoft Visual Studio 6

Microsoft Visual Studio 6 is very old, but if you still have it installed, you can use it to build this hlsdk. There are no project files, but two .bat files, for server and client libraries. They require variable MSVCDir to be set to the installation path of Visual Studio:

set MSVCDir=C:\Program Files\Microsoft Visual Studio
cd dlls && compile.bat && cd ../cl_dll && compile.bat

hl.dll and client.dll will appear in dlls/ and cl_dll/ diretories. The libraries built with msvc6 should be compatible with Windows XP.

Linux. Using Steam Runtime in chroot

Prerequisites

The official way to build Steam compatible games for Linux is through steam-runtime.

Install schroot. On Ubuntu or Debian:

sudo apt install schroot

Clone https://github.com/ValveSoftware/steam-runtime and follow instructions: download and setup the chroot.

sudo ./setup_chroot.sh --i386 --tarball ./com.valvesoftware.SteamRuntime.Sdk-i386-scout-sysroot.tar.gz

Building

Now you can use cmake and make prepending the commands with schroot --chroot steamrt_scout_i386 --:

mkdir build-in-steamrt && cd build-in-steamrt
schroot --chroot steamrt_scout_i386 -- cmake ..
schroot --chroot steamrt_scout_i386 -- make

Linux. Build without Steam Runtime

Prerequisites

Install C++ compilers, cmake and x86 development libraries for C, C++ and SDL2. On Ubuntu/Debian:

sudo apt install cmake build-essential gcc-multilib g++-multilib libsdl2-dev:i386

Building

mkdir build && cd build
cmake ..
make

Note that the libraries built this way might be not compatible with Steam Half-Life. If you have such issue you can configure it to build statically with c++ and gcc libraries:

cmake .. -DCMAKE_C_FLAGS="-static-libstdc++ -static-libgcc"

To ensure portability it's still better to build using Steam Runtime or another chroot of some older distro.

Linux. Build in your own chroot

Prerequisites

Use the most suitable way for you to create an old distro 32-bit chroot. E.g. on Ubuntu/Debian you can use debootstrap.

sudo apt install debootstrap schroot
sudo mkdir -p /var/choots
sudo debootstrap --arch=i386 jessie /var/chroots/jessie-i386 # On Ubuntu type trusty instead of jessie
sudo chroot /var/chroots/jessie-i386
# inside chroot
apt install cmake build-essential gcc-multilib g++-multilib libsdl2-dev
exit

Create and adapt the following config in /etc/schroot/chroot.d/jessie.conf (you can choose a different name):

[jessie]
type=directory
description=Debian jessie i386
directory=/var/chroots/jessie-i386/
users=yourusername
groups=adm
root-groups=root
preserve-environment=true
personality=linux32

Insert your actual user name in place of yourusername.

Building

Prepend any make or cmake call with schroot -c jessie --:

mkdir build-in-chroot && cd build-in-chroot
schroot --chroot jessie -- cmake ..
schroot --chroot jessie -- make

Linux. Crosscompiling using mingw

Note that GoldSource won't work with libraries compiled with mingw.

TODO: do we need this section at all? Is Xash3D-FWGS distributed with support for game libraries built with mingw?

Prerequisites

Install mingw. On Ubuntu/Debian:

sudo apt-get install -y mingw-w64-i686-dev binutils-mingw-w64-i686 gcc-mingw-w64-i686 g++-mingw-w64-i686

Building

mkdir build-mingw && cd build-mingw
TOOLCHAIN_PREFIX=i686-w64-mingw32 # check up the actual mingw prefix of your mingw installation
cmake .. -DCMAKE_SYSTEM_NAME=Windows -DCMAKE_C_COMPILER="$TOOLCHAIN_PREFIX-gcc" -DCMAKE_CXX_COMPILER="$TOOLCHAIN_PREFIX-g++"

Android

TODO

Other platforms

Building on other Unix-like platforms (e.g. FreeBSD) is supported.

Prerequisites

Install C and C++ compilers (like gcc or clang), cmake and make (or gmake)

Building

mkdir build && cd build
cmake ..
make

Building with waf

To use waf, you need to install python (2.7 minimum)

(./waf configure -T release)
(./waf)

Build options

Some useful build options that can be set during the cmake step.

  • GOLDSOURCE_SUPPORT - allows to turn off/on the support for GoldSource input. Set to ON by default on Windows and Linux, OFF on other platforms.
  • USE_VGUI - whether to use VGUI library. OFF by default. You need to init vgui_support submodule in order to build with VGUI.

This list is incomplete. Look at CMakeLists.txt to see all available options.

Prepend option names with -D when passing to cmake. Boolean options can take values OFF and ON. Example:

cmake .. -DUSE_VGUI=ON -DGOLDSOURCE_SUPPORT=ON -DCROWBAR_IDLE_ANIM=ON -DCROWBAR_FIX_RAPID_CROWBAR=ON
