This guide covers the process of compiling the NeL engine using Visual Studio 2019 or later on Windows. The steps below will help you set up the environment, clone the repository, and build the project.
Download and extract the 3rd party external libraries package.
Make sure to have the following tools and SDKs installed on your system.
Open a command line terminal, and browse to a directory where you want to build your project. Clone the Ryzom Core repository from GitHub into a ryzomcore subdirectory.
git clone https://github.com/ryzom/ryzomcore.git
Create a build directory under the ryzomcore repository folder and navigate to it.
cd ryzomcore
mkdir build
cd build
Run CMake with the tools, samples, and Assimp set to ON, and MFC, Qt, Ryzom, NeLNS, and Snowballs set to OFF. Replace the paths in the CMAKE_PREFIX_PATH option with the appropriate paths for your system.
cmake -G "Visual Studio 17 2022" -DWITH_NEL_TOOLS=ON -DWITH_NEL_SAMPLES=ON -DWITH_ASSIMP=ON -DWITH_NEL_TESTS=OFF -DWITH_MFC=OFF -DWITH_QT=OFF -DWITH_RYZOM=OFF -DWITH_NELNS=OFF -DWITH_SNOWBALLS=OFF -DWITH_EXTERNAL=OFF -DWITH_STATIC_LIBXML2=OFF -DWITH_STATIC_CURL=OFF -DWITH_LUA51=OFF -DWITH_LUA52=ON "-DCMAKE_PREFIX_PATH=C:\2022q2_external_v143_x64\zlib;C:\2022q2_external_v143_x64\openssl;C:\2022q2_external_v143_x64\curl;C:\2022q2_external_v143_x64\libjpeg;C:\2022q2_external_v143_x64\libpng;C:\2022q2_external_v143_x64\libxml2;C:\2022q2_external_v143_x64\freetype;C:\2022q2_external_v143_x64\squish;C:\2022q2_external_v143_x64\ogg;C:\2022q2_external_v143_x64\vorbis;C:\2022q2_external_v143_x64\ffmpeg;C:\2022q2_external_v143_x64\openal-soft;C:\2022q2_external_v143_x64\lua;C:\2022q2_external_v143_x64\luabind;C:\2022q2_external_v143_x64\ffmpeg;C:\2022q2_external_v143_x64\mariadb-connector-c;C:\2022q2_external_v143_x64\assimp;C:\2022q2_external_v143_x64\qt5;C:\2022q2_external_v143_x64\boost" ..
Open the RyzomCore.sln file in the build folder. Switch to the Debug build target, and hit the Build Solution button to build your project. This might take a while!
