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