@section install_sec Installation

FACT++ can be downloaded from the svn by

\verbatim
   svn checkout https://www.fact-project.org/svn/trunk/FACT++ [localdir]
\endverbatim

it includes a dim version which is automatically compiled.

For compilation use

\verbatim
   ./configure
   make
\endverbatim

Check the \b ./configure options with \b --help. It might look 
confusing, but some features like FITS or QT4 can be switched off,
if the necessary library is not at hand and the feature is not needed.
For example, if the GUI is not needed its compilation can be switched
off by disabling QT4 support with \b --without-qt4.

If you use a custom built root version on your system without QT 
support, but have a distribution packe (e.g. debian package) with
QT support available, you can give the path to root executables,
for example, with <B>--with-rootsys=/usr/bin</B>. All other paths
are extracted from subsequent calls to \b root-config.

Running \b ./configure will take some time. It tries to really check
carefully that everything needed is available on your system, so that you 
get errors before you start compilation.

If \b ./configure fails and you send a bug report please attach
the file config.log.

If \b make fails and you send a bug report please attach
the complete output of <B>make V=1</B>.

\b Reminder: These programs use shared libraries, i.e. whenever you re-compile
part of the project some of them might be re-compiled as well. As a result
already running programs might crash unexpectedly! This is \b not a bug.

In principle configure also supports

\verbatim
   make install
\endverbatim

which would install the package and the libraries in your system,
although at the moment this is not recommended

@subsection rootwarning ROOT warnings during compilation

During compilation of the GUI you get some warning from root's
TQtWidget.h. These warnings are completely harmless and can be ignored.
However, it is sometimes advicable to get rid of them to get a clean
compiler run which makes development easier.

Therefore replace
\verbatim
inline void resize(const QSize &size) { QPixmap newSize(size); *(QPixmap *)this = newSize; }
\endverbatim
by
\verbatim
inline void resize(const QSize &sz) { QPixmap newSize(sz); *(QPixmap *)this = newSize; }
\endverbatim
in TQtWidget.h


@subsection packages Required packages

The following section gives a list of packages which were necessary after
a fresh Ubuntu 11.04 installation. In addition to all the development
packages the corresponding package with the library is needed.

Note that a recent C++ compiler is needed supporting the latest C++0x 
standard.

<i>Required (configure will fail without them)</i>
- subversion
- gcc 
- g++ 
- make 
- libreadline6-dev 
- libboost-all-dev 
- libx11-dev (needed for lesstif, qt4, root)

<i>FITS file support (datalogger, event builder)</i>
- libccfits-dev 

<i>MySQL support (command line options, scheduler)</i>
- libmysqlclient-dev (optional for MySQL support)
- libmysql++-dev (option for MySQL support)

<i>If you want 'did'</i>
- lesstif2-dev

<i>For JavaScrip support</i>
- libv8-dev

<i>To compile the GUIs</i>
- libqt4-dev
- root (see section about root, currently recommended versions 5.18/00b-5.26/00e)

<i>To compile the raw data viewer</i>
- libglu1-mesa-dev

<i>To compile smartfact with astronomy support and moon</i>
- libnova-dev

<i>To compile tngweather</i>
- libsoprano-dev

<i>To compile skypeclient</i>
- libdbus-1-dev
- libdbus-glib-1-dev

<i>To create your own documentation</i>
- graphviz
- doxygen
- help2man
- groff 
- ps2pdf

<i>To create JavaScript documentation</i>
- jsdoc-toolkit

<i>For developers</i>
- autoconf
- autoconf-archive
- libtool
- qt4-designer

If you intend to change only Makefile.am but not configure.ac the \b automake
package instead of the \b autoconf package should be enough.

<i>Some nice to have (FACT++)</i>
- colorgcc
- colordiff

<i>Some nice to have (system)</i>
- fte
- efte
- htop

<i>Documentation (usually accessible through http://localhost/ for the tools above:</I>
- autoconf-doc
- gcc-doc
- graphviz-doc
- libboost-doc
- libmysql++-doc
- libtool-doc
- make-doc
- qt4-dev-tools [qt4-assistant]
- qt4-doc-html

@subsection installroot How to install root 5.26/00 on Ubuntu 11.04 (natty)

- install gpp4.4, gcc4.4, g++4.4 (root does not compile with gcc4.5)
- make links to hidden X11 libraries:
<B><pre>
cd /usr/local
sudo ln -s x86_64-linux-gnu/libX* .
</pre></B>
- in the root source directory
<B><pre>
./configure --enable-qt --with-cc=gcc-4.4 --with-cxx=g++-4.4 --with-xrootd-opts=--syslibs=/usr/lib/x86_64-linux-gnu --prefix=/usr/local
</pre></B>
- \b make
- <b>sudo make install</b>
- pray
- don't forget to set LD_LIBRARY_PATH correctly before you try to start the fact gui


@section demos Current demonstration programs

- \b dserver2: A virtual board (A TCP/IP server). It is sending a
  "hello" message after accepting a communication and then in 3s
  intervals the current UTC time. The board can be set to state 1 or back
  to state 0 (just as a demonstration)
- \b dclient5: A control program. It accesses two viratual boards (start them
  with 'dserver2 5000' and 'dserver2 4001') If both boards are connected the START
  command can be issued to get them to state 'Running'. In this state
  an asynchronous time stamp can be requested sending the TIME command.
  to get back from Running to Connected use STOP. 
- \b test3: a dim console which allows to control all dim servers
  by sending commands via the dim network.
- Both, \b dclient5 and \b test3 accept the command line options -c0, -c1, -c2
  to switch between different console types (or no console in the case of
  \b dclient5). In the console you get help with 'h' and the available
  command with 'c' You get the avilable command-line options with --help

First start the two dserver2s. Then start a dclient5 (if you want it
with console use one of the -c options) and a test3 console (with one
of the console options if you like) you can now control the hardware
boards with the START, STOP and TIME commands or stop (Ctrl-C) and
start one of the programs to see what's happening. In the test3 case
you first have to \e cd to the server to which you want to talk by \b
DATA_LOGGER. Don't forget to start \b dns if you want to control dclient5
from test3 via Dim.

@section dimremarks Remarks about Dim usage

To be able to write all received data directly to the FITS files,
padding has been disabled calling dic_diable_padding() and 
dis_disable_padding(). This is done in our own error handler
DimErrorRedirecter. Since this should be one of the first 
objects created in any environment it is quite save. However, every
Dim client or server in our network which does not use the 
DimErrorRedirecter \b must call these two functions as early as
possible.

@section blocking Blocking programs at startup

At startup most programs try to resolve the name of the dim-dns
as well as their local IP address. After this Dim is initialized 
and tries to contact the dns. These are so far the only blocking operations.
Be patient at program startup. They will usually timeout after a while and
give you proper informations.


@section addtab How to add a new tab in the gui?

Do the following steps in exactly this order:
- Insert the new page from the context menu of the QTabWidget
- Copy the QDockWidget from one of the other tabs to the clipboard
- Paste the copied QDockWidget and add it to the new tab (only the tab should be highlited)
- Now click on the context menu of the region in the tab (QWidget) and change the layout to grid layout


@section Documentation

Each program has an extensive help text (except the examples). This
help text can be displayed with the \b --help option. For each program
a man-page is automatically created (from the help-output), which (at
the moment) can be accessed with <B>man ./program.man</B> (Don't forget
the ./ before the filename). With <B>make program.html</B> and 
<B>make program.pdf</B> a HTML page and a pdf document can be created
from the man-page.

With <B>make doxygen-doc</B> the HTML documentation as well as a pdf
with the whole code documentation can be created.

@subsection FACT++ programs

Each documentation is also available with <B>program --help</B> or
<B>man ./program.man</B>.
