+1. Overview
+===========
+This package provides a compilation of shared libraries of the ALICE
HLT project and is intended for stand-alone compilation, i.e. not as part
of the AliRoot compilation.
-- BASE: The base library (libHLTbase.so) provides the common interface for HLT
-processing components, the binding into the ALICE offline project AliRoot
-and a pure C interface to the HLT on-line framework (Publisher/Subscriber
-framework)

+ - \b PHOS: The HLT code for PHOS
-Currently, the the package is not included to the standard AliRoot
-compilation, but will be part of it.
+ - \b TRD: The HLT code for TRD
-The old stand-alone build system is still available. Check the README

-Requirements
-============
+2. Requirements
+===============
The package needs both ROOT and AliRoot. Both must be set up in the
usual way (ROOTSYS, ALICE_ROOT, library locations evtl. specified in
LD_LIBRARY_PATH, ...). Actually, the BASE and SampleLib modules are
not dependend on AliRoot. The TPCLib does.
-Setting up a version retrieved from CVS
-=======================================
+To set up a version retrieved from SVN, autoconf 2.57, automake 1.6
+,and libtool 1.4 or higher versions are required. Thats the versions
+which come with the Scientific Linux CERN 3. The same applies if
+you want to change the Makefiles.
+
+If your GNU build tools are too old, ask the maintainers for a distributed
+package.
+
+3. Setting up a version retrieved from SVN
+==========================================
Skip this section if you have started from the tar ball.
-A version checked out from CVS requires a few steps to set up the Makefiles
-and to set some links which are related to the CVS structure at the IFT.
+A version checked out from SVN requires a few steps to set up the Makefiles.
Go to the directory and run
-autoreconf -i -f
+
+ autoreconf -i -f
Then continue with the package configuration described in the 'Installation'
section.
-Modifying a distributed package
-===============================
+4. Modifying a distributed package
+==================================
If you are going the modify a distributed package you might need to re-make
the GNU build system by running
- autoreconf -f -i
+
+ autoreconf -f -i
Please notify the authors about bug fixes/corrections/extensions you made if
you consider them worth to be merged into the project.
Then continue with the package configuration described in the 'Installation'
section.
-Installation
-============
+5. Installation
+===============
Package build relies on the GNU triplet configure, make and make install.
-It is suggested to use a separate build directory, e.g. from the
-top directory do
+In order to keep the development directory clean, it is recommended to
+use a separate build directory.
+
+\b NOTE: Autotools creates the Makefiles from templates. All \b changes have to
+be done to the \b Makefile.am templates.
+
+It is recommended to read the complete section before the build process.
+
+5.1 For the impatiant user
+--------------------------
mkdir build
cd build
make
make install
-The default install directories are set to the current directory ($PWD).
+5.2 Installation directory
+--------------------------
+The default install directory is set to the current directory ($PWD). To
+override the default directory use the option
+ --prefix=<dir>.
+More information can be obtained from the configure script by running it with
+option --help. All binary libraries will be installed under
+ <prefix>/lib.
+
+If the directory is equal to $ALICE_ROOT, the libraries will be installed under
+ <prefix>/lib/tgt_<arch>
+as used for AliRoot. This is a custom extension in
+order to adapt to the specific AliRoot installation directories.
-To override the default prefix use
---prefix=<dir>
+5.3 For the AliRoot user
+------------------------
+To install all libraries in the AliRoot lib dir:
+
+ mkdir build
+ cd build
+ ../configure --prefix=$ALICE_ROOT
+ make
+ make install
-Some important options:
---enable-logging # Enable/Disable logging (default enabled)
---enable-sample # Compile the sample library
---enable-tpc # Compile the TPC library
+5.4 Package options
+-------------------
+Some important options (all options are on by default):
-Note: You can have several build directories with different configure options,
-but using the same source code.
+ --disable-sample # disable compilation the sample library
+ --disable-util # disable compilation the util library
+ --disable-tpc # disable compilation the TPC library
+ --disable-phos # disable compilation the PHOS library
+ --disable-trd # disable compilation the TRD library
+ --disable-dimuon # disable compilation the MUON library
+ --disable-aliroot-logging # disable logging
+ --disable-doc # disable creation of doxygen documentation
+ --disable-strict # disable strict coding conventions and compilation flags
+
+
+All detector libraries (including sample and util lib) require AliRoot,
+compilation is disabled if no working AliRoot version was found. This can
+occur even if an AliRoot version is set up correctly since the configure
+script checks for the usability of the AliRoot libraries (mainly STEER and
+the ones it depends on). If new dependencies are introduced, the check
+might fail.
+
+Compilation of detector libraries can be forced by the switch
+
+ --enable-detector, e.g. --enable-phos
+
+Compilation can also be forced by typing 'make' in the detector
+sub-directory.
+
+Debugging (default disabled)
+
+ --enable-debug # enable debugging: symbols & messages
+
+Optimization (default -O2)
+
+ --disable-optimization # disable compiler optimization
+ --enable-optimization<=l> # enable compiler optimization level l
+
+5.5 External packages
+---------------------
+PubSub framework: the TPC online display needs the HOMER interface, which
+is currently part of the PubSub framework. It is planned to integrate it
+into AliRoot.<br>
+If the TPC online display is not necessary one can skip this option.
+
+ --with-pubsub=<dir> # the top dir of the HLT PubSub framework
+
+5.6 Final remarks/further information
+-------------------------------------
+\b Note: You can have several build directories with different configure
+options, but using the same source code.
If you need further information on the GNU build system, execute from the
top directory:
-./configure --help | less
+ ./configure --help | less
+
+
+6. Documentation
+================
+Documentation is build as part of the build process if \b doxygen is installed.
+The documentation can be opended from the
+ doc/html/
+sub-folder of your build directory. E.g with a web browser like firefox
+(assuming you are in the build directory):<br>
+ firefox file://`pwd`/doc/html/index.html
+
+A special target can be used to make a tar ball out of the documentation (again
+provided you are in the build directory):<br>
+ (cd doc && make tar-ball)
-Documentation
-=============
-Documentation is generated from the source code at compile time if
-doxygen is installed on the machine. From the build directory, open
-doc/html/index.html with a web browser.
+On-line documentation is available at
+ http://web.ift.uib.no/~kjeks/doc/alice-hlt/
-Further information
-===================
+7. Further information
+======================
A wiki with detailed information is set up at
-http://www.kip.uni-heidelberg.de/wiki/HLT
+ http://www.kip.uni-heidelberg.de/wiki/HLT
+
+8. Reporting bugs/Asking for support
+====================================
+Please include the following information into your report/request:
+ - config.log from your build directory
+ - output of the make process. Note: Redirect BOTH the stdout and stderr
+ channel to a log file. Redirection depends on the shell you are using: <br>
+ bash: make 2>&1 | tee make.log <br>
+ csh: make |& tee make.log <br>
+ The 'tee' command just duplicates the output.
+ - history of the commands you are using for compilation
+ history > history.log
+
+9. Committing to the AliRoot SVN
+================================
+For development of HLT analysis code check out a HEAD version from the
+repository and implement your code.
+
+For committing do:
+ - 1. make sure that the code changes are correct <br><tt>
+ svn diff | less </tt><br>
+ \b Remember to restore all temporary changes you made (e.g. log level)
+ - 2. svn update
+ - 3. correct merging conflicts
+ - 4. compile and test your code again
+ - 5. depending on where you changes are send the whole HLT module except the build
+ sub-directories or your HLT sub- directory to
+ Matthias.Richter@ift.uib.no
+ Please include a message/description for the check in
+ - 6. you will get a notification when the code is committed, right after that
+ you must either do another svn update or check out the complete module
+ again in order to have the right SVN information. Please check that your
+ code has been correctly committed.
