2 Note: The CMake build of AliRoot builds out-of-source
4 Steps to Build AliRoot with CMake :
6 1. Check out Aliroot source into a folder (usually specified by the environment variable ALICE)
9 svn co http://alisoft.cern.ch/AliRoot/trunk AliRoot
11 2. Set the environment variable ALICE_ROOT to point to the source you have checked out
14 export ALICE_ROOT=`pwd`
17 3. Create a new folder where the build will take place. It must be different from the source directory!
23 4. Optionally specify the place for installation using the environment variable ALICE_INSTALL.
24 It you do not specify it, "make install" will put lib, bin and include in ALICE_ROOT
26 5. Optionally specify the location of Geant3 using the environment variable GEANT3DIR
28 6. Execute the following commands to configure the build
32 Note: Some files CMakeLists.txt will be created in the source tree, so you need write access there. This
33 is a temporary situation that will change soon.
35 7. Build and install AliRoot. Note that the parralel build is fully operational with CMake.
40 If you make changes in the source tree, it is enough to do
47 9. In order to build addtional targets like THydjet and SHUTTLE add the following options to the cmake command
49 cmake -DTHydjet=ON -DSHUTTLE=ON <path_to_source>
51 10. Static libraries can be built using
55 11. Individual Modules can be built using
58 make <Module>-all-static
60 eg. make STEER-all STEER-all-static
62 12. Individual Packages can be built using
67 eg. make STEERbase STEERbase-static
69 13. The code can be checked for the ALICE coding conventions on a package, module or class level using the following targets.
72 make <Module>-check-all
74 make <Module>-<ClassName>-check // To use this run cmake with -DCLASSCHECK="YES" option. It is turned off by default since it bloats the Makefile and slows down the internal makefile rule checking
76 The resulting violations will be written to the folder <Build_Directory>/<Module>/check/viols
78 14. To Build PARs the following targets can be used. The resulting packages will be created in the cmake build directory
82 make <Module>-par-all //build all par packages in the module
84 15. To test PARs after building run
88 make test-<Module>-par-all
90 !IMPORTANT! - Make sure your source folder is clean. If you used the old make system to build aliroot run make clean in the source directory before you run cmake
