Guide to building OGRE

Ogre uses CMake as its build system on all supported platforms. This guide will explain to you how to use CMake to build Ogre from source. You need a CMake version >= 3.10.

What is CMake?

CMake is a cross-platform build system - or perhaps more accurately a build configurator. It is a program which, from a set of CMake scripts, creates a native build system for your platform that allows you to build Ogre. The build process is configurable via CMake. Ogre provides several options which you can use to customise your build.

Preparing the build environment

You should now create a build directory for Ogre somewhere outside Ogre's sources. This is the directory where CMake will create the build system for your chosen platform and compiler, and this is also where the Ogre libraries will be compiled. This way, the Ogre source dir stays clean, and you can have multiple build directories (e.g. for Android and for Linux) all working from the same Ogre source.

Getting dependencies

By default ogre will build the recommended dependencies automatically when you run cmake configure the first time. Ogre will install the dependencies into the subfolder Dependencies in the build dir by default. You can configure it by setting OGRE_DEPENDENCIES_DIR in cmake.

As the dependencies are built during the configure stage of CMake, you must specify the desired CMAKE_BUILD_TYPE via command-line. Changing the value in the CMake GUI will have no effect.

If you would rather use system wide libraries set OGRE_BUILD_DEPENDENCIES=OFF. On windows, you would then point OGRE_DEPENDENCIES_DIR to a common dependencies folder for all of your middleware projects. Inside this directory you must have the subdirectories bin, lib and include where you place .dll, .lib and header files of the dependencies, respectively.

For manually building the dependencies, please refer to the list below and get a source package from the website, then build it according to its documentation.


On linux you additionally need the following system headers to build the GL, GL3+, GLES2 & Vulkan RenderSystems:

  • Ubuntu

    sudo apt-get install libgles2-mesa-dev libvulkan-dev glslang-dev libxrandr-dev

  • Fedora

    sudo dnf install mesa-libGL-devel mesa-vulkan-devel glslang-devel

furthermore we recommend installing the following optional packages

  • Ubuntu

    sudo apt-get install libsdl2-dev libxt-dev libxaw7-dev doxygen

  • Fedora

    sudo dnf install SDL2-devel libXt-devel libXaw-devel doxygen pugixml-devel

these will enable input handling in the SampleBrowser, the X11 ConfigDialog and allow building the documentation.

Optional dependencies

Running CMake

Now start the program cmake-gui by either typing the name in a console or selecting it from the start menu. In the field Where is the source code enter the path to the Ogre source directory (the directory which contains this file). In the field Where to build the binaries enter the path to the build directory you created. Hit Configure. A dialogue will appear asking you to select a generator.

Check the CMake documentation for details on which one is appropriate for your platform and compiler.

on OSX, you must to use the Xcode generator to get a proper SampleBrowser .app bundle.

Click Finish. CMake will now gather some information about your build environment and try to locate the dependencies. It will then show a list of build options. You can adjust the settings to your liking;

  • unchecking any of the OGRE_BUILD_XXX options will disable that particular component/ plugin from being built
  • OGRE_CONFIG_XXX on the other hand allows you to configure Core features e.g. threading or zip file support.
  • OGRE_CONFIG_NODE_INHERIT_TRANSFORM enables shearing and non-uniform scaling for Ogre::SceneNode. This requires slightly more storage and computation time.
  • OGRE_CONFIG_ENABLE_MESHLOD If enabled, LOD levels from *.mesh files are used to reduce triangle count. If disabled, they are skipped at loading. Reducing submesh size and entity size.
  • OGRE_PROFILING add profiling instrumentation the ogre library.
  • OGRE_PROFILING_REMOTERY_PATH if set, Remotery is used for profiling instead of the Ogre internal profiler.
  • OGRE_ASSERT_MODE allows you to to disable all runtime assertion exceptions or turn them into calls to std::abort.
  • OGRE_RESOURCEMANGER_STRICT allows you to turn on resource lookup related quirks for pre ogre 1.10 compatibility.
  • OGRE_NODELESS_POSITIONING allows to use Lights and Cameras without attaching them to nodes (only for legacy code).

Once you are satisfied, hit Configure again and then click on Generate. CMake will then create the build system for you.


Go to your chosen build directory. CMake has generated a build system for you which you will now use to build Ogre. If you are using Visual Studio, you should find the file OGRE.sln. Open it and compile the target BUILD_ALL. Similarly you will find an Xcode project to build Ogre on MacOS.

If you rather want to trigger the build form a console, then cd to your build directory and call the appropriate make program as

cmake --build . --config Release

to start the build process.

on multi-config generators, notably Xcode and MSVC, --config must match the CMAKE_BUILD_TYPE specified when building the dependencies. This does not apply if you manually provide the dependencies as release and debug.

If you have doxygen installed and CMake picked it up, then there will be an additional build target called OgreDoc which you can optionally build. This will freshly generate the API documentation for Ogre's classes from the header files. In Visual Studio, just select and build the target OgreDoc, on Linux type:

 make OgreDoc


Once the build is complete, the libraries and headers must be copied to a clean location. This is required if you want to reference Ogre in your own projects with CMake. In Visual Studio, just select and build the target INSTALL. When using the command line, type:

cmake --build . --config Release --target install

For Makefile based generators, type:

make install  # (or sudo make install, if root privileges are required)

On Linux Ogre will be installed to /usr/local by default. On Windows this will create the folder sdk inside your build directory and copy all the required libraries there. You can change the install location by changing the variable CMAKE_INSTALL_PREFIX in CMake.

Installing and building via vcpkg

You can download and install ogre using the vcpkg dependency manager:

git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
./vcpkg integrate install
vcpkg install ogre

The ogre port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please create an issue or pull request on the vcpkg repository.


Building on Ubuntu for Android

To build Ogre for Android, you need to specify the android cross toolchain to cmake as

cmake -DCMAKE_TOOLCHAIN_FILE=path/to/android-ndk/build/cmake/android.toolchain.cmake -DANDROID_NDK=path/to/android-ndk .

this will build the core Ogre libraries. Additionally it will create gradle projects OgreJNI for using Java bindings and SampleBrowserNDK for the C++ only Sample Browser.

You can now import these projects in Android Studio or manually trigger the APK creation by changing into the project folders and running

gradle assembleRelease

Building for WebAssembly (using Emscripten)

Install the Emscripten SDK (see full documentation on www.emscripten.org), and make sure that the environment variables are correctly set (eg. run source <emsdk_path>/emsdk_env.sh before attempting to build)

Run cmake in cross compile mode using emscripten as following:

mkdir build-wasm
emcmake cmake .. -DCMAKE_BUILD_TYPE=Release
emmake make

NB: to simplify the process, 'emcmake' and 'emmake' wrappers are used. These tools are provided by Emscripten to correctly setup the cross compilation environment

This will not build the full SampleBrowser, but just a minimal Sample. The resulting EmscriptenSample.html will be placed in ${CMAKE_BINARY_DIR}/bin/.

To prevent any cross-origin issues, start a local webserver as python3 -m http.server 8000 and visit http://localhost:8000.

Building on Mac OS X for iOS OS

To build Ogre for iOS, you need to specify the ios cross toolchain to cmake as

cmake -DCMAKE_TOOLCHAIN_FILE=CMake/toolchain/ios.toolchain.xcode.cmake -DIOS_PLATFORM=SIMULATOR -G Xcode .

Unfortunately, you will now have to do a few manual steps to make the generated build system work properly.

A Xcode project has now been generated in the build directory, so to start the Ogre build, open OGRE.xcodeproj and build as usual. To run samples on your device you will need to have a valid iOS Developer certificate installed. For each sample, double click on target in the Groups & Files list. Ensure that a valid identity is selected in the Code Signing Identity drop menu. Also, because we can't tell CMake what Xcode project format you want, you will have to change it yourself. Open the Project Menu, choose Edit Project Settings. Click on the General tab in the settings window. Change Project Format to Xcode 3.1-compatible. And another thing. You will need to manually set the Bundle Identifier property of the Info.plist file to match the App ID of the chosen code signing identity. This can be done from the Target Properties panel. It must match the bundle identifier of a valid developer certificate if you are building for devices.

Building as Windows Store or Windows Phone application

You need Windows 8.0 or later, Windows 10 is recommended.

Visual Studio 2015 is recommended as it is bundled with Universal, WinStore 8.0/8.1 and WinPhone 8.0/8.1 SDKs.

Dependencies for Win32 and for WinRT must be located in separate folders. Cg is not supported.

cmake.exe -G "Visual Studio 15 2017" -DCMAKE_SYSTEM_NAME=WindowsStore -DCMAKE_SYSTEM_VERSION=10.0 ..

Select SampleBrowser as the start up project and run.

  1. The code and generated CMake solution should be on local NTFS drive, and can't be on a network drive, including VMWare shared folders - or you will get a errors when you will try to compile/link/run resulting exe.
  2. Ogre uses d3dcompiler_xx.dll to compile shaders, and WinStore and WinPhone 8.1 projects can use it without restriction as it is part of OS. But WinStore and WinPhone 8.0 applications should load already compiled shaders from cache, as d3dcompiler_xx.dll is available to them only during development. Therefore to avoid necessity to deploy d3dcompiler_xx.dll during development (additional configurations with d3dcompiler_xx.dll) and generation of such cache - use version 8.1 of these platforms.
  3. Running WinPhone emulator in OS running under VMware: We were able to run the emulation and debug without an issue by using two steps: (a) Under the settings of the VM > CPU, make sure you have the option to pass-through the Intel VT-x/EPT feature, (b) Edit the config file .vmx and add the parameter: hypervisor.cpuid.v0 = "FALSE" All versions of Visual Studio 2012 have a window refresh issue when running in VMware and the window is maximized, the solution is just to change the size of the Visual Studio window to be less the the screen width and height.
