28 | 1. Overview | |
29 | =========== | |
0fc7626e | 30 | This package provides a compilation of shared libraries of the ALICE |
08e73b29 | 31 | HLT project and is intended for stand-alone compilation, i.e. not as part |
32 | of the AliRoot compilation. | |
33 | ||
9be2600f | 34 | - \b BASE: The base library (libHLTbase.so) provides the common interface for |
35 | HLT processing components, the binding into the ALICE offline project | |
36 | AliRoot and a pure C interface to the HLT on-line framework | |
37 | (Publisher/Subscriber framework) | |
08e73b29 | 38 | |
9be2600f | 39 | - \b SampleLib: The sample library contains examples for component |
40 | implementation and a tutorial. | |
b521659f | 41 | |
9be2600f | 42 | - \b TPCLib: The HLT code for the TPC |
43 | - \b TPCLib/OnlineDisplay: HLT visualization code for the TPC | |
fc455fba | 44 | |
9be2600f | 45 | - \b PHOS: The HLT code for PHOS |
08e73b29 | 46 | |
9be2600f | 47 | - \b TRD: The HLT code for TRD |
08e73b29 | 48 | |
1e27470a | 49 | - \b MUON: The HLT code for MUON |
50 | ||
c160eda8 | 51 | 2. Requirements |
52 | =============== | |
08e73b29 | 53 | The package needs both ROOT and AliRoot. Both must be set up in the |
54 | usual way (ROOTSYS, ALICE_ROOT, library locations evtl. specified in | |
55 | LD_LIBRARY_PATH, ...). Actually, the BASE and SampleLib modules are | |
56 | not dependend on AliRoot. The TPCLib does. | |
57 | ||
78b557c2 | 58 | To set up a version retrieved from CVS, autoconf 2.57, automake 1.6 |
59 | ,and libtool 1.4 or higher versions are required. Thats the versions | |
60 | which come with the Scientific Linux CERN 3. The same applies if | |
61 | you want to change the Makefiles. | |
62 | ||
63 | If your GNU build tools are too old, ask the maintainers for a distributed | |
64 | package. | |
65 | ||
c160eda8 | 66 | 3. Setting up a version retrieved from CVS |
67 | ========================================== | |
b521659f | 68 | Skip this section if you have started from the tar ball. |
69 | ||
0fc7626e | 70 | A version checked out from CVS requires a few steps to set up the Makefiles. |
b521659f | 71 | Go to the directory and run |
9be2600f | 72 | |
73 | autoreconf -i -f | |
b521659f | 74 | |
75 | Then continue with the package configuration described in the 'Installation' | |
76 | section. | |
77 | ||
c160eda8 | 78 | 4. Modifying a distributed package |
79 | ================================== | |
b521659f | 80 | If you are going the modify a distributed package you might need to re-make |
81 | the GNU build system by running | |
9be2600f | 82 | |
83 | autoreconf -f -i | |
b521659f | 84 | |
85 | Please notify the authors about bug fixes/corrections/extensions you made if | |
86 | you consider them worth to be merged into the project. | |
87 | ||
88 | Then continue with the package configuration described in the 'Installation' | |
89 | section. | |
90 | ||
c160eda8 | 91 | 5. Installation |
92 | =============== | |
b521659f | 93 | Package build relies on the GNU triplet configure, make and make install. |
0fc7626e | 94 | In order to keep the development directory clean, it is recommended to |
95 | use a separate build directory. | |
b521659f | 96 | |
9be2600f | 97 | \b NOTE: Autotools creates the Makefiles from templates. All \b changes have to |
98 | be done to the \b Makefile.am templates. | |
99 | ||
fc455fba | 100 | It is recommended to read the complete section before the build process. |
101 | ||
102 | 5.1 For the impatiant user | |
103 | -------------------------- | |
104 | ||
b521659f | 105 | mkdir build |
106 | cd build | |
107 | ../configure | |
108 | make | |
109 | make install | |
110 | ||
fc455fba | 111 | 5.2 Installation directory |
112 | -------------------------- | |
600e6a1b | 113 | The default install directory is set to the current directory ($PWD). To |
9be2600f | 114 | override the default directory use the option |
115 | --prefix=<dir>. | |
116 | More information can be obtained from the configure script by running it with | |
117 | option --help. All binary libraries will be installed under | |
118 | <prefix>/lib. | |
119 | ||
120 | If the directory is equal to $ALICE_ROOT, the libraries will be installed under | |
121 | <prefix>/lib/tgt_<arch> | |
122 | as used for AliRoot. This is a custom extension in | |
6c1a9d9e | 123 | order to adapt to the specific AliRoot installation directories. |
b521659f | 124 | |
fc455fba | 125 | 5.3 For the AliRoot user |
126 | ------------------------ | |
127 | To install all libraries in the AliRoot lib dir: | |
128 | ||
129 | mkdir build | |
130 | cd build | |
131 | ../configure --prefix=$ALICE_ROOT | |
132 | make | |
133 | make install | |
b521659f | 134 | |
fc455fba | 135 | 5.4 Package options |
136 | ------------------- | |
137 | Some important options (all options are on by default): | |
9be2600f | 138 | |
139 | --disable-sample # disable compilation the sample library | |
c018a1bd | 140 | --disable-util # disable compilation the util library |
9be2600f | 141 | --disable-tpc # disable compilation the TPC library |
142 | --disable-phos # disable compilation the PHOS library | |
143 | --disable-trd # disable compilation the TRD library | |
c018a1bd | 144 | --disable-dimuon # disable compilation the MUON library |
9be2600f | 145 | --disable-aliroot-logging # disable logging |
fc455fba | 146 | |
c018a1bd | 147 | All detector libraries (including sample and util lib) require AliRoot, |
148 | compilation is disabled if no working AliRoot version was found. This can | |
149 | occur even if an AliRoot version is set up correctly since the configure | |
150 | script checks for the usability of the AliRoot libraries (mainly STEER and | |
151 | the ones it depends on). If new dependencies are introduced, the check | |
152 | might fail. | |
153 | ||
154 | Compilation of detector libraries can be forced by the switch | |
155 | ||
156 | --enable-detector, e.g. --enable-phos | |
157 | ||
1e27470a | 158 | Debugging (default disabled) |
159 | ||
160 | --enable-debug # enable debugging: symbols & messages | |
161 | ||
162 | Optimization (default -O2) | |
163 | ||
164 | --disable-optimization # disable compiler optimization | |
165 | --enable-optimization<=l> # enable compiler optimization level l | |
166 | ||
fc455fba | 167 | 5.5 External packages |
168 | --------------------- | |
169 | PubSub framework: the TPC online display needs the HOMER interface, which | |
170 | is currently part of the PubSub framework. It is planned to integrate it | |
9be2600f | 171 | into AliRoot.<br> |
fc455fba | 172 | If the TPC online display is not necessary one can skip this option. |
9be2600f | 173 | |
174 | --with-pubsub=<dir> # the top dir of the HLT PubSub framework | |
fc455fba | 175 | |
176 | 5.6 Final remarks/further information | |
177 | ------------------------------------- | |
9be2600f | 178 | \b Note: You can have several build directories with different configure |
179 | options, but using the same source code. | |
08e73b29 | 180 | |
b521659f | 181 | If you need further information on the GNU build system, execute from the |
182 | top directory: | |
9be2600f | 183 | |
184 | ./configure --help | less | |
b521659f | 185 | |
186 | ||
c160eda8 | 187 | 6. Documentation |
188 | ================ | |
9be2600f | 189 | Documentation is build as part of the build process if \b doxygen is installed. |
190 | The documentation can be opended from the | |
191 | doc/html/ | |
192 | sub-folder of your build directory. E.g with a web browser like firefox | |
193 | (assuming you are in the build directory):<br> | |
194 | firefox file://`pwd`/doc/html/index.html | |
195 | ||
196 | A special target can be used to make a tar ball out of the documentation (again | |
197 | provided you are in the build directory):<br> | |
198 | (cd doc && make tar-ball) | |
199 | ||
200 | On-line documentation is available at | |
201 | http://web.ift.uib.no/~kjeks/doc/alice-hlt/ | |
08e73b29 | 202 | |
c160eda8 | 203 | 7. Further information |
204 | ====================== | |
b521659f | 205 | A wiki with detailed information is set up at |
9be2600f | 206 | http://www.kip.uni-heidelberg.de/wiki/HLT |
0fc7626e | 207 | |
c160eda8 | 208 | 8. Reporting bugs/Asking for support |
209 | ==================================== | |
0fc7626e | 210 | Please include the following information into your request: |
9be2600f | 211 | - config.log from your build directory |
212 | - output of the make process. Note: Redirect BOTH the stdout and stderr | |
1e27470a | 213 | channel to a log file. Redirection depends on the shell you are using: <br> |
214 | bash: make 2>&1 | tee make.log <br> | |
215 | csh: make |& tee make.log <br> | |
9be2600f | 216 | The 'tee' command just duplicates the output. |
217 | - history of the commands you are using for compilation | |
218 | history > history.log | |
c160eda8 | 219 | |
220 | 9. Committing to the AliRoot CVS | |
221 | ================================ | |
222 | For development of HLT analysis code check out a HEAD version from the | |
600e6a1b | 223 | repository and implement your code. |
224 | ||
225 | For committing do: | |
9be2600f | 226 | - 1. make sure that the code changes are correct <br><tt> |
227 | cvs diff | less </tt><br> | |
228 | \b Remember to restore all temporary changes you made (e.g. log level) | |
229 | - 2. cvs update | |
230 | - 3. correct merging conflicts | |
231 | - 4. compile and test your code again | |
232 | - 5. send the whole HLT module except the build sub-directories to | |
233 | Matthias.Richter@ift.uib.no | |
234 | - 6. you will get a notification when the code is committed, right after that | |
235 | you must either do another cvs update or check out the complete module | |
236 | again in order to have the right CVS information. |
