Compiling

Prerequisites

Windows

• Microsoft Visual Studio 2022 with Desktop development with C++ workload

Linux

• CMake 3.24 or newer
• g++ 14 or newer or clang++ 18 or newer

Compiling from source

Windows

Open Osiris.sln in Visual Studio 2022, set build configuration to Release | x64. Press Build solution and you should receive Osiris.dll file.

Linux

Configure with CMake:

cmake -DCMAKE_BUILD_TYPE=Release -B build

Build:

cmake --build build -j $(nproc --all)

After following these steps you should receive libOsiris.so file in build/Source/ directory.

Loading / Injecting into game process

Windows

You need a DLL injector to inject (load) Osiris.dll into game process.

Counter-Strike 2 blocks LoadLibrary injection method, so you have to use a manual mapping (aka reflective DLL injection) injector.

Xenos and Extreme Injector are known to be detected by VAC.

Linux

You can simply run the following script in the directory containing libOsiris.so:

sudo gdb -batch-silent -p $(pidof cs2) -ex "call (void*)dlopen(\"$PWD/libOsiris.so\", 2)"

However, this injection method might be detected by VAC as gdb is visible under TracerPid in /proc/$(pidof cs2)/status for the duration of the injection.

FAQ

Where are the settings stored on disk?

In a configuration file default.cfg inside %appdata%\OsirisCS2\configs directory on Windows and $HOME/OsirisCS2/configs on Linux.
