13 This package provides is a compilation of shared libraries of the ALICE
14 HLT project and is intended for stand-alone compilation, i.e. not as part
15 of the AliRoot compilation.
17 - BASE: The base library (libHLTbase.so) provides the common interface for HLT
18 processing components, the binding into the ALICE offline project AliRoot
19 and a pure C interface to the HLT on-line framework (Publisher/Subscriber
22 - SampleLib: The sample library contains examples for component
23 implementation and a tutorial.
25 - TPCLib: The HLT code for the TPC
27 Currently, the the package is not included to the standard AliRoot
28 compilation, but will be part of it.
30 The old stand-alone build system is still available. Check the README
31 file in the doc folder.
35 The package needs both ROOT and AliRoot. Both must be set up in the
36 usual way (ROOTSYS, ALICE_ROOT, library locations evtl. specified in
37 LD_LIBRARY_PATH, ...). Actually, the BASE and SampleLib modules are
38 not dependend on AliRoot. The TPCLib does.
40 To set up a version retrieved from CVS, autoconf 2.57, automake 1.6
41 ,and libtool 1.4 or higher versions are required. Thats the versions
42 which come with the Scientific Linux CERN 3. The same applies if
43 you want to change the Makefiles.
45 If your GNU build tools are too old, ask the maintainers for a distributed
48 Setting up a version retrieved from CVS
49 =======================================
50 Skip this section if you have started from the tar ball.
52 A version checked out from CVS requires a few steps to set up the Makefiles
53 and to set some links which are related to the CVS structure at the IFT.
54 Go to the directory and run
57 Then continue with the package configuration described in the 'Installation'
60 Modifying a distributed package
61 ===============================
62 If you are going the modify a distributed package you might need to re-make
63 the GNU build system by running
66 Please notify the authors about bug fixes/corrections/extensions you made if
67 you consider them worth to be merged into the project.
69 Then continue with the package configuration described in the 'Installation'
74 NOTE: The Makefiles which are in repository are port of the old build system.
75 Now, the Makefile.am templates are valid.
77 Package build relies on the GNU triplet configure, make and make install.
78 For historical reasons there are Makefiles around from the old build system.
79 In order to avoid messing up the two build strategies, it is recommended to
80 use a separate build directory, e.g. from the top directory do
88 The default install directories are set to the current directory ($PWD).
90 To override the default prefix use
93 Some important options:
94 --enable-logging # Enable/Disable logging (default enabled)
95 --enable-sample # Compile the sample library
96 --enable-tpc # Compile the TPC library
98 Note: You can have several build directories with different configure options,
99 but using the same source code.
101 If you need further information on the GNU build system, execute from the
103 ./configure --help | less
108 Documentation is generated from the source code at compile time if
109 doxygen is installed on the machine. From the build directory, open
110 doc/html/index.html with a web browser.
