1. Overview
===========
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)

2. Requirements
===============
LD_LIBRARY_PATH, ...). Actually, the BASE and SampleLib modules are
not dependend on AliRoot. The TPCLib does.
-To set up a version retrieved from CVS, autoconf 2.57, automake 1.6
+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 CVS
+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.
+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.
==================================
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.
5. Installation
===============
-NOTE: The Makefiles which are in repository are part of the old build system.
-Now, the Makefile.am templates are valid.
-
Package build relies on the GNU triplet configure, make and make install.
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
../configure
make
make install
-You should redirect the output of the make into a file.
-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.
-To override the default prefix use
---prefix=<dir>
+If the directory is equal to $ALICE_ROOT, the libraries will be installed under
+ <prefix>/lib/tgt_<arch>
+as used for AliRoot. This is a custom extension in
+order to adapt to the specific AliRoot installation directories.
-Some important options:
---enable-logging # Enable/Disable logging (default enabled)
---enable-sample # Compile the sample library
---enable-tpc # Compile the TPC library
+5.3 For the AliRoot user
+------------------------
+To install all libraries in the AliRoot lib dir:
-Note: You can have several build directories with different configure options,
-but using the same source code.
+ mkdir build
+ cd build
+ ../configure --prefix=$ALICE_ROOT
+ make
+ make install
+
+5.4 Package options
+-------------------
+Some important options (all options are on by default):
+
+ --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 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.
+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)
+
+On-line documentation is available at
+ http://web.ift.uib.no/~kjeks/doc/alice-hlt/
7. Further information
======================
A wiki with detailed information is set up at
-http://www.kip.uni-heidelberg.de/wiki/HLT

8. Reporting bugs/Asking for support
====================================
-Please include the following information into your 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:
- bash: make 2>&1 | tee make.log
- csh: make |& tee make.log
- The 'tee' command just duplicates the output.
-- history of the commands you are using for compilation
- history > history.log
-
-9. Committing to the AliRoot CVS
+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. cvs update
-2. correct merging conflicts
-3. compile and test your code again
-4. send the whole HLT module except the build sub-directories to
- Matthias.Richter@ift.uib.no
-5. you will get a notification when the code is committed, right after that you
- must either do another cvs update or check out the complete module again in
- order to have the right CVS information
+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.
