Each linux distribution will come with varying components already installed, although some libraries may be older than the version required by FreeOrion. Hopefully the notes below will help to identify what is required for your particular distribution.
- 1 Compiler
- 2 Kernel
- 3 Platform specifics
- 4 Ogre3D
- 5 GiGi
- 6 Bullet
- 7 FreeOrion
- 8 User stories
- 9 Compilation Errors
- 10 Runtime Errors
- 11 IDE for development
- 12 Debugging
Required compiler is gcc and g++ in version 4.3.3 or above.
If you compile using kernel 2.6.22 or above, your binary will likely not run on any other system having a lower numbered kernel version. This is due to a feature called "eventfd" which boost uses if a kernel 2.6.22 or above is found.
To avoid this incompatibility, you can specify CPPDEFINES="BOOST_ASIO_DISABLE_EVENTFD" as a parameter to scons to disable usage of eventfd.
This issue should not be a problem at all if you don't share your binaries.
Ubuntu Lucid Lynx
Ubuntu (Maverick and Lucid)
To build gigi or FreeOrion you first need to install the following packages using Synaptic (you will need to have the Universe repository included):
You can install all of these (including dependencies) from the command line using this:
sudo apt-get install build-essential subversion pkg-config libltdl3-dev cmake sudo apt-get install python2.6-dev libfreetype6-dev libsdl1.2-dev libalut-dev libvorbis-dev libois-dev libtiff4-dev libopenal-dev libogre-dev
Bullet 2.73(or later), which is required to compile, is not in the official Ubuntu repository.
Ubuntu Maverick Boost
sudo apt-get install libboost-dev libboost1.42-all-dev --install-recommends
Ubuntu Lucid Boost
You have to compile required version of Boost(in Lucid there is no version 1.42 or later) or get it from some repository.
Same as Ubuntu, but Bullet 2.73(or later), which is required to compile, is not in Debian repository. Also remove sudo from all commands and run these commands under root(to login type su). Ogre3D in required version is available only from Squeeze up.
Lenny provides version 1.35 of boost. You have to compile version 1.44 (or later) yourself.
Squeeze (testing) & Sid (unstable)
You can install Boost and Ogre3D with command(under user root):
apt-get install libboost-dev libboost1.42-all-dev --install-recommends
From Debian Squeeze and Ubuntu Lucid up there is no need to do next Ogre3D steps. However Debian Lenny does not provide ogre-dev binary package in required version. One can be found from http://www.cazfi.net/deb or in Andrew Fenn's repository.
(sudo) add-apt-repository ppa:andrewfenn (sudo) apt-get install libogre-dev
and install new Ogre3D. If you prefer to compile Ogre3D yourself, read on.
Ubuntu and Debian
Install Ogre3D requirements
(sudo) apt-get install automake (sudo) apt-get install libzzip-dev libfreeimage-dev x11proto-xf86vidmode-dev libxxf86vm-dev (sudo) apt-get install libpcre3-dev libfreetype6-dev libxrandr-dev libxaw7-dev libmng-dev libglew1.5-dev libxt-dev
Download Ogre3D sources and unpack them. Supported compiler g++ and gcc versions is only version 4.3 or 4.4.
should return version 4.3 or 4.4
Compile Ogre3D with
aclocal ./bootstrap ./configure make
and install with:
(sudo) make install (sudo) ldconfig
Before attempting to build FreeOrion you will first need to build and install the GiGi library, including GiGiOgre and the GiGiOgre OIS plugin. Before building GiGi you also need Ogre installed.
The GiGi source should be automatically downloaded from SVN along with the FreeOrion source code.
Change into the GiGi directory and build the library:
cd freeorion/FreeOrion/GG cmake -DBUILD_TUTORIALS=off -DBUILD_OGRE_DRIVER=ON -DBUILD_OGRE_OIS_PLUGIN=ON . make (sudo) make install (sudo) ldconfig
Add line as root
to file /etc/ld.so.conf
Bullet debian packets for some Debian/Ubuntu releases and architectures can be found from http://build.cazfi.net/deb/
Install Bullet compilation requirements
(sudo) apt-get install freeglut3-dev
After downloading and unpacking downloaded bullet archive, compile it with:
cmake -D BUILD_SHARED_LIBS=true . make
and install with:
(sudo) make install cd /usr/local/lib (sudo) ln -s libBulletCollision.so libbulletcollision.so (sudo) ln -s libBulletDynamics.so libbulletdynamics.so (sudo) ln -s libLinearMath.so libbulletmath.so (sudo) ldconfig
Symlinks libbulletcollision.so, libbulletdynamics.so and libbulletmath.so are required to create because bullet build system is inconsistent on different platforms.
- Create symlinks of Ogre plugins to locations where plugins are installed /usr/lib/OGRE (from repository Ogre3D) or /usr/local/lib/OGRE (compiled Ogre3D):
cd freeorion/FreeOrion ln -s /usr/lib/OGRE/Plugin_OctreeSceneManager.so . ln -s /usr/lib/OGRE/Plugin_ParticleFX.so . ln -s /usr/lib/OGRE/RenderSystem_GL.so . ln -s /usr/lib/OGRE/Plugin_BSPSceneManager.so . ln -s /usr/lib/OGRE/Plugin_OctreeZone.so . ln -s /usr/lib/OGRE/Plugin_PCZSceneManager.so .
- or change Ogre3D plugin folder location in file ogre_plugins.cfg to where OGRE libs are installed(need to be done after every FreeOrion compilation):
After GiGi is compiled and installed, compile FreeOrion:
cd freeorion/FreeOrion cmake . make
If you have less than 8 GB of RAM, you might have errors during compiling relating to the compiler running out of heap space. In this case, try
to specify that make should only use one thread, which should limit memory consumption. The flag
might also help.
When improvements have been made to FreeOrion, you should keep it up to date with:
cd freeorion/FreeOrion svn update
This should update GG and FreeOrion from subversion. After compiling and installing GG compile FreeOrion.
Clean After Dependency Changes
It may be necessary to clean your old build before rebuilding GiGi or FreeOrion after updates that make changes to dependencies or versions of dependencies used, such as Boost. Do this in FreeOrion and GG directory:
rm CMakeCache.txt make clean
Bogus build errors
You may see errors during the build process like this:
-- Build platform: linux -- Configuring GiGi -- Configuring GiGiSDL -- Configuring GiGiOgre -- checking for one of the modules 'OGRE' Warning: Ogre could not be found. Disabling the Ogre build. -- Configuring Ogre OIS Input Plugin -- checking for one of the modules 'OIS' Warning: OIS could not be found. Disabling the OIS build. -- Configuring Tutorials -- Could NOT find Doxygen (missing: DOXYGEN_EXECUTABLE) Warning: Doxygen could not be found. Disabling the documentation build. -- Configuring done -- Generating done
These failed messages refer to cmake not finding an installed package for these components.
Cmake can't find libraries/dependencies
If cmake is not able to find a library (e.g. Ogre, OIS, etc) that is installed, please see this thread
no matching function for call to 'swap(adobe::version_1::any_regular_t&, adobe::version_1::any_regular_t&)'
- Upgrade compiler gcc and g++ at least to version 4.3.3 or
- Change line 734 of GG/adobe/any_regular.hpp from
If after compiling everything, you run freeorion and get a segmentation fault:
$ ./freeorion Segmentation fault
- Be certain that currently installed driver for your graphic card supports OpenGL 2.0 or later
- You might be mixing dependencies compiled with different versions of GCC or different optimization level for Ogre, GiGi and FreeOrion. See this post
- You have graphic card which doesn't support shader model 3 or above(Nvidia 6600 and above have, some AMD HD series also). There are known problems with AMD drivers on Linux. In future there will be functional Gallium driver(r300g or r600g) in Mesa. These new drivers will be available probably in Ubuntu 11.04.
Video mode set failed: Couldn't find matching GLX visual
Your video mode is probably set to 16-bit instead of 32-bit, which is what FreeOrion defaults to. You need to either change your X server color depth to 32-bit, or edit the FreeOrion config file in ~/freeorion/config.xml and change color-depth from 32 to 16. You can also try the command line argement:
./freeorion --color-depth 16
IDE for development
- Text editor and cmake with make to compile.
- Eclipse is open source multiplatform IDE and can be used to compile FreeOrion, but plugins to support subversion and python have to be installed. See howto Compile With Eclipse.
Adding debug symbols to binary
Turn on debugging symbols on GG and FreeOrion with:
cmake -DBUILD_DEBUG=1 .
and then rebuild GG and FreeOrion.
Install debugger gdb and run freeorion in window mode(not in fullscreen) with:
and after it starts gdb type
and wait until segfault occurs. Then to print backtrace type
