Building OrionUO

This project requires CMake 3.7 to build. It currently supports Visual Studio 2015, 2017, GCC 7.0 and Clang 6.

Windows

On Windows, to generate the Visual Studio solution, go inside your cloned OrionUO folder and do:

md build
cd build
cmake -G "Visual Studio 2017" ..

This will build a 32bits executable. If you do want 64bits, you can do cmake -G "Visual Studio 2017 Win64" .. instead. Note that plugins are still unsupported in the 64bits client.

Or, you can use CMake-GUI to configure and generate the solution.

• If you want to help converting OrionUO to SDL, you can disable ORION_WISP option in CMake. This option enables the original client implementation in pure win32 API and is kept as a reference implementation to use during the client conversion to SDL.

Linux (in progress)

$ mkdir build
$ cd build
$ cmake -G Ninja .. -DCMAKE_BUILD_TYPE=Release
$ ninja OrionUO_unity -j8
$ ./OrionUO/unity/OrionUO

You'll need a Client.cuo and a OrionUO.cfg in the working directory. Inside OrionUO.cfg you can add a line CustomPath=/path/to/uo/data, so OrionUO will be able to find your original client data files.
