43 For developers using the git tree:
45 This source tree is based on the autotools suite from GNU to simplify
46 portability. Here are some things you should have on your system in order to
47 compile the git repository tree :
49 - GNU autotools (automake >=1.10, autoconf >=2.50, autoheader >=2.50)
50 (make sure your system wide "automake" points to a recent version!)
52 (for more information, go to http://www.gnu.org/software/autoconf/)
54 (Before this version we hit a known bug documented at:
55 http://sourceware.org/bugzilla/show_bug.cgi?id=11317)
59 If you get the tree from the repository, you will need to use the "bootstrap"
60 script in the root of the tree. It calls all the GNU tools needed to prepare the
63 INSTALLATION INSTRUCTIONS:
65 - Download, compile and install the prerequisites.
72 If compiling from the git repository, run ./bootstrap before running
73 the configure script, to generate it.
75 If you want Python bindings, run ./configure --enable-python-bindings.
79 Please see doc/quickstart.txt to help you start tracing. You can also use the
80 -h/--help command on 'lttng' and all other commands offered in this tool (Ex:
81 lttng enable-event -h).
83 A network streaming HOWTO can be found in doc/streaming-howto.txt which quickly
84 helps you understand how to stream a LTTng 2.0 trace.
86 A Python HOWTO can be found in doc/python-howto.txt which quickly
87 helps you understand how to use the Python module to control the LTTng API.

106 - libkernel-consumer (internal)
107 Library for Kernel consumer control
109 - libust-consumer (internal)
110 Library for UST consumer control
112 - libhashtable (internal)
113 Library wrapper over URCU hashtables.
115 - libcommon (internal)
116 Contains multiple useful function call used by the whole tree.
118 - libcompat (internal)
119 Compatibility library mostly for FreeBSD and Linux.
121 - librelayd (internal)
122 Library for all relayd interactions over the network.
125 The relay daemon used for network streaming
128 The consumer daemon which uses libconsumer.
131 The LTTng session daemon binary.
134 The LTTng tracer command line control tool.
136 - include (lttng.h --> installed in $(includedir)/lttng/lttng.h)
137 The liblttngctl API header file.
