LTTng Trace Control

----------------

Please visit http://lttng.org for more information.

Latest development can be found at:

    * Gitweb :  http://git.lttng.org/lttng-tools.git/

    * Git :     git://git.lttng.org/lttng-tools.git

REQUIREMENTS:

	- Linux kernel >= 2.6.27

	  pipe2(), epoll_create1() and SOCK_CLOEXEC are needed to run the session

	  daemon. There were introduce in the Linux 2.6.27

    - liburcu

      Userspace RCU library, by Mathieu Desnoyers and Paul E. McKenney

      -> Tested with liburcu >= v0.7.2

      * Debian/Ubuntu package: liburcu-dev

      * Git : git://git.lttng.org/userspace-rcu.git

      * Website:  http://lttng.org/urcu

    - libpopt >= 1.13

      Library for parsing command line parameters

      * Debian/Ubuntu package: libpopt-dev

    - Perl (optional)

      Needed for make check and tests.

    - SWIG >= 2.0 (optional)

      Needed for Python bindings (--enable-python-bindings).

      * Debian/Ubuntu package: swig2.0

    - python-dev (optional)

      Python headers

      * Debian/Ubuntu package: python-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 http://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.

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.

	- libust-consumer (internal)

	  Library for UST consumer control

	- libhashtable (internal)

	  Library wrapper over URCU hashtables.

	- libcommon (internal)

	  Contains multiple useful function call used by the whole tree.

	- libcompat (internal)

	  Compatibility library mostly for FreeBSD and Linux.

	

	- librelayd (internal)

	  Library for all relayd interactions over the network.

	- lttng-relayd

	  The relay daemon used for network streaming

    - lttng-consumerd

      The consumer daemon which uses libconsumer.

    - lttng-sessiond

      The LTTng session daemon binary.

    - lttng

      The LTTng tracer command line control tool.

    - include (lttng.h --> installed in $(includedir)/lttng/lttng.h)

      The liblttngctl API header file.

    - tests

      Various test programs.
