Steps to Build AliRoot with CMake :
-1. Check out Aliroot source into any folder
+1. Check out Aliroot source into a folder (usually specified by the environment variable ALICE)
- svn co http://alisoft.cern.ch/AliRoot/trunk ~/trunk
+ cd $ALICE
+ svn co https://alisoft.cern.ch/AliRoot/trunk AliRoot
-2. Create a new folder and set the environment variable ALICE_ROOT to point to it
+Note: Please use https:// if you want to be able to commit changes to the SVN repository.
+
+2. Set the environment variable ALICE_ROOT to point to the source you have checked out
+
+ cd AliRoot
+ export ALICE_ROOT=`pwd`
+
+
+3. Create a new folder where the build will take place. It must be different from the source directory!
- mkdir AliRoot
- cd AliRoot
- export ALICE_ROOT=`pwd`
+ cd ..
+ mkdir objdir
+ cd objdir
+
+4. Optionally specify the place for installation using the environment variable ALICE_INSTALL.
+It you do not specify it, "make install" will put lib, bin and include in ALICE_ROOT
+
+5. Optionally specify the location of Geant3 using the environment variable GEANT3DIR
+
+6. Execute the following commands to configure the build
+
+ cmake $ALICE_ROOT
+
+
+Note: Some files CMakeLists.txt will be created in the source tree, so you need write access there. This
+is a temporary situation that will change soon.
+
+ 6a.Run
+ cmake -DCMAKE_BUILD_TYPE=DEBUG $ALICE_ROOT
+ to compile AliRoot in Debug configuration (-g compiler flags).
+
+ To change the configuration later on you can either
+ edit cache variable CMAKE_BUILD_TYPE using 'ccmake' command ('None' value for default configuration),
+
+ or setup default configuration (-O -g flags are setting up) by running
+ cmake $ALICE_ROOT
+
+ 6b. To compile AliRoot in Release mode (-03 flag) run
+ cmake -DCMAKE_BUILD_TYPE=Release $ALICE_ROOT
+
+ 6c. Command
+ cmake -DCMAKE_BUILD_TYPE=RelRelWithDebInfo $ALICE_ROOT
+ allows to compile AliRoot with -g -O2 options.
+
+Please note! The default values for these flags change with different compilers.
+If CMake does not know your compiler, the contents will be empty.
+
+
+7. Build and install AliRoot. Note that the parralel build is fully operational with CMake.
-3. Execute the following commands to build AliRoot
+ make -j4
+ make install
- cmake ~/trunk
- make
+If you make changes in the source tree, it is enough to do
-4. In order to build addtional targets like THydjet and SHUTTLE add the following options to the cmake command
+ make
+ make install
+
+to get them in use.
+
+9. In order to build addtional targets like THydjet and SHUTTLE add the following options to the cmake command
cmake -DTHydjet=ON -DSHUTTLE=ON <path_to_source>
+10. Static libraries can be built using
-!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
-
+ make alilibs-static
+
+11. Individual Modules can be built using
+
+ make <Module>-all
+ make <Module>-all-static
+
+eg. make STEER-all STEER-all-static
+
+12. Individual Packages can be built using
+
+ make <Package>
+ make <Package>-static
+
+eg. make STEERbase STEERbase-static
+13. The code can be checked for the ALICE coding conventions on a package, module or class level using the following targets.
+
+ make check-all
+ make <Module>-check-all
+ make <Package>-check
+ 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
+
+ The resulting violations will be written to the folder <Build_Directory>/<Module>/check/viols
+
+14. To Build PARs the following targets can be used. The resulting packages will be created in the cmake build directory
+
+ make par-all
+ make <Package>.par
+ make <Module>-par-all //build all par packages in the module
+
+15. To test PARs after building run
+
+ make test-par-all
+ make test-<Package>
+ make test-<Module>-par-all
+
+!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
