44 - For kernel tracing: modprobe
47 Needed for running "make check".
49 For developers using the git tree:
51 This source tree is based on the autotools suite from GNU to simplify
52 portability. Here are some things you should have on your system in order to
53 compile the git repository tree :
55 - GNU autotools (automake >=1.10, autoconf >=2.50, autoheader >=2.50)
56 (make sure your system wide "automake" points to a recent version!)
58 (for more information, go to http://www.gnu.org/software/autoconf/)
62 If you use GNU gold, which is NOT mandatory, make sure you have this version:
64 (Before this version we hit a known bug documented at:
65 http://sourceware.org/bugzilla/show_bug.cgi?id=11317)
66 Be advise that with GNU gold, you'll might have to specify -L/usr/local/lib in
69 If you get the tree from the repository, you will need to use the "bootstrap"
70 script in the root of the tree. It calls all the GNU tools needed to prepare
71 the tree configuration.
73 INSTALLATION INSTRUCTIONS:
75 - Download, compile and install the prerequisites.
83 If compiling from the git repository, run ./bootstrap before running
84 the configure script, to generate it.
86 If you want Python bindings, run ./configure --enable-python-bindings.
90 Please see doc/quickstart.txt to help you start tracing. You can also use the
91 -h/--help command on 'lttng' and all other commands offered in this tool (Ex:
92 lttng enable-event -h).
94 A network streaming HOWTO can be found in doc/streaming-howto.txt which quickly
95 helps you understand how to stream a LTTng 2.0 trace.
97 A Python HOWTO can be found in doc/python-howto.txt which quickly
98 helps you understand how to use the Python module to control the LTTng API.
