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

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.

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.

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.
