Requirements

• C++20
• A supported compiler
• Python 3.11
• Ninja 1.11.1
• cmake 3.28.0
• Vulkan 1.3.211.0

3rd Party Libraries

• myl
• spdlog

Getting Started

1. Nativate to Mythos/scripts and run setup. If needed the python file can also be ran manually, however submodules should be updated and initialized beforehand.
2. Follow any instructions provided by the setup script. Mythos' scripts will attempt to find any required programs on your system before requesting a download. Download URLs are located in the respective setup_**.py file in the Mythos/scripts/python directory.
3. Mythos should now be ready to be built and compiled.
4. Build and compile Mythos using a supported compiler and build target.
5. Mythos should be ready to use!

Building Mythos

1. Run cmake and select your desired configuration. Build Mythos, if the build fails see Common Issues
2. The executable will be located in Mythos/build/bin/{configuration}.

Supported Tooling

Compilers

• MSVC
• Clang

Common Issues

Incorrect Controller Inputs

If you have Steam installed, it's possible Steam is hijacking the controller's data and modifying it. This can be resolved 2 ways.

• Steam -> Settings -> Controller -> set Enable Steam Input for [Xbox/Switch Pro/generic] controllers to off, for PlayStation controllers set PlayStation Controller Support to Not Enabled.
• End Steam as a process from task manager.

CMAKE_MT-NOTFOUND

If the build failed due to CMAKE_MT-NOTFOUND this is because CMake could not find the manifest tool. This is likely to occur when attempting to build for Windows with Clang.

On Windows when compiling with Clang-CL and not using Visual Studio, this occurs because vcvarsall.bat has not set up the enviroment correctly, unfortunately editors like VS-Code can't set up that enviroment provided by vcvarsall.bat. This can be resolved by solution 3 below.

On Windows this can possibly be solved by one of the following methods;

1. Adding the parent directory of the manifest tool (mt.exe) to the PATH system enviromental variable. This should be the easiest solution.
2. Running vcvarsall.bat and specifying the platform_type, eg: x64.
3. Manually setting CMAKE_MT in a CMakeUserPresets.json file (See below). The manifest tool should be located in "C:/Program Files (x86)/Windows Kits/10/bin/{WINDOWS SDK VERSION}/{PLATFORM TYPE}"
