== Compiling FACT++ ==

First you need to get FACT++ from the svn-repository

{{{svn checkout https://www.fact-project.org/svn/trunk/FACT++}}}

Now create a new subdirectory

{{{
cd FACT++
mkdir build
}}}

And call {{{cmake}}} from there

{{{
cmake ..
}}}

to compile with clang, you might want to do
{{{
cmake -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ ..
}}}

Note that not all versions of clang are compatible with all version of the boost-libraries.

If you only want to compile the basic tools (like rootifysql) you can add {{{-DTOOLS_ONLY=1}}} when calling {{{cmake}}}.

If a package is missing, you will see an error which looks like this

{{{
CMake Error at /usr/share/cmake-3.10/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
  Could NOT find Nova (missing: NOVA_LIBRARY NOVA_INCLUDE_DIR)
Call Stack (most recent call first):
  /usr/share/cmake-3.10/Modules/FindPackageHandleStandardArgs.cmake:378 (_FPHSA_FAILURE_MESSAGE)
  cmake/FindNova.cmake:11 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
  CMakeLists.txt:131 (FIND_PACKAGE)
}}}

It is a bit tricky to find out which package is missing at the moment. In this case, it is the development package of the nova library (libnova-dev).

Then call {{{make}}}.

== Packaging FACT++ ==

For the tool-set, you can build a archive file and Debian packages by {{{make package}}}. The Debian package can then be installed with {{{dpkg -i fact++-YYWWDDHH.deb}}} while YYWWDDHH is the version number compiled from the time when cmake was called.
