-LTTng Trace Control
-----------------
-
-Please visit https://lttng.org for more information. The current maintainer is
-David Goulet <dgoulet@efficios.com>.
-
-Latest development can be found at:
-
- * Gitweb : https://git.lttng.org/?p=lttng-tools.git;a=summary
- * Git : git://git.lttng.org/lttng-tools.git
-
-REQUIREMENTS:
-
- - Linux kernel >= 2.6.27
- For epoll() support, at least this version is needed. However, poll() is
- also supported by running "./configure --disable-epoll". Using that, the
- kernel version can probably be older but we can't provide any guarantee.
- Please let us know if you are able to go lower without any problems.
-
- - liburcu >= 0.8.0
- Userspace RCU library, by Mathieu Desnoyers and Paul E. McKenney
-
- -> Tested with liburcu 0.8.x stable.
-
- * Debian/Ubuntu package: liburcu-dev
- * Git : git://git.lttng.org/userspace-rcu.git
- * Website: https://lttng.org/urcu
-
- - libpopt >= 1.13
- Library for parsing command line parameters
-
- * Debian/Ubuntu package: libpopt-dev
-
- - libuuid
- Universally unique id library
-
- * Debian/Ubuntu package: uuid-dev
-
- - Babeltrace (optional)
- Trace viewer. Enable the use of "lttng view" command
-
- * Debian/Ubuntu package: babeltrace
-
- - libxml2 >= 2.7.6
- XML document parsing library.
-
- * Debian/Ubuntu package: libxml2-dev
-
- - Perl (optional)
- Needed for make check and tests.
-
- - Python >= 3.0 (optional)
- Needed for make check and tests.
-
- * Debian/Ubuntu package: python3
-
- - SWIG >= 2.0 (optional)
- Needed for Python bindings (--enable-python-bindings).
-
- * Debian/Ubuntu package: swig2.0
-
- - python-dev (optional)
- Python headers
-
- * Debian/Ubuntu package: python3-dev
-
- - For kernel tracing: modprobe
-
- - bash
- Needed for running "make check".
-
-For developers using the git tree:
-
-This source tree is based on the autotools suite from GNU to simplify
-portability. Here are some things you should have on your system in order to
-compile the git repository tree :
-
-- GNU autotools (automake >=1.10, autoconf >=2.50, autoheader >=2.50)
- (make sure your system wide "automake" points to a recent version!)
-- GNU Libtool >=2.2
- (for more information, go to https://www.gnu.org/software/autoconf/)
-- flex >= 2.5.35
-- bison >= 2.4
-
-If you use GNU gold, which is NOT mandatory, make sure you have this version:
-- GNU gold >= 2.22
-(Before this version we hit a known bug documented at:
- http://sourceware.org/bugzilla/show_bug.cgi?id=11317)
-Be advise that with GNU gold, you'll might have to specify -L/usr/local/lib in
-LDFLAGS.
-
-If you get the tree from the repository, you will need to use the "bootstrap"
-script in the root of the tree. It calls all the GNU tools needed to prepare
-the tree configuration.
-
-INSTALLATION INSTRUCTIONS:
-
- - Download, compile and install the prerequisites.
- Then:
- $ ./boostrap
- $ ./configure
- $ make
- $ sudo make install
- $ sudo ldconfig
-
- If compiling from the git repository, run ./bootstrap before running
- the configure script, to generate it.
-
- If you want Python bindings, run ./configure --enable-python-bindings.
- Please note that some distributions will need the following
- environment variables set before running configure:
-
- export PYTHON="python3"
- export PYTHON_CONFIG="/usr/bin/python3-config"
-
-USAGE:
-
-Please see doc/quickstart.txt to help you start tracing. You can also use the
--h/--help command on 'lttng' and all other commands offered in this tool (Ex:
-lttng enable-event -h).
-
-A network streaming HOWTO can be found in doc/streaming-howto.txt which quickly
-helps you understand how to stream a LTTng 2.0 trace.
-
-A Python HOWTO can be found in doc/python-howto.txt which quickly
-helps you understand how to use the Python module to control the LTTng API.
