31 For developers using the git tree:
32
33 This source tree is based on the autotools suite from GNU to simplify
34 portability. Here are some things you should have on your system in order to
35 compile the git repository tree :
36
37 - GNU autotools (automake >=1.10, autoconf >=2.50, autoheader >=2.50)
38 (make sure your system wide "automake" points to a recent version!)
39 - GNU Libtool >=2.2
40 (for more information, go to http://www.gnu.org/software/autoconf/)
41
42 If you get the tree from the repository, you will need to use the "bootstrap"
43 script in the root of the tree. It calls all the GNU tools needed to prepare the
44 tree configuration.
45
46 INSTALLATION INSTRUCTIONS:
47
48 - Download, compile and install the prerequisites.
49 Then:
50 $ ./configure
51 $ make
52 $ sudo make install
53 $ sudo ldconfig
54
55 If compiling from the git repository, run ./bootstrap before running
56 the configure script, to generate it.
57
58 USAGE:

61 -h/--help command on 'lttng' and all other commands offered in this tool (Ex:
