# INSTALL
#---------------------------------------------------------------------

There are currently 2 wasy to build musrfit:

1) via the automake tool chain (this will phase out until 2019)
2) via the cmake tool chain (this will be the default starting from now)

In the following it is assumed that the system variable ROOTSYS is already
defined and pointing to the place where CERN/ROOT is installed.

#----------------------------------
# Install via automake tool chain
#----------------------------------

To get it build:

   sh autogen.sh
   ./configure --prefix=$ROOTSYS             (or where ever musrfit should be installed)
   make
   make install                              (as superuser -- maybe)
   /sbin/ldconfig                            (as superuser)   

configure comes with a couple of options. For details either execute

  ./configure --help

or check under http://lmu.web.psi.ch/musrfit/user/MUSR/MusrFitSetup.html
for a more detailed description.

An example with NeXus support and BMWlibs needed would look like this

   sh autogen.sh
   ./configure --enable-NeXus --enable-BMWlibs --prefix=$ROOTSYS 
   make 
   make install                              (as superuser -- maybe)
   /sbin/ldconfig                            (as superuser)
   
In the optimal case, everything is set up ;-)

#----------------------------------
# Install via cmake tool chain
#----------------------------------

cmake minimal required version is 3.6.

musrfit supports only out-of-source cmake build! Hence, go to the musrfit
directory and

   mkdir build
   cd build 
   cmake ../ -DCMAKE_INSTALL_PREFIX=$ROOTSYS (or where ever musrfit should be installed)
   cmake --build ./ --clean-first
   make install                              (as superuser -- maybe)
   /sbin/ldconfig                            (as superuser)
    
cmake configuration allows a couple of switches.  For details check the user
docu under 

   http://lmu.web.psi.ch/musrfit/user/MUSR/MusrFitSetup.html

An example with NeXus support and BMWlibs needed would look like this

   mkdir build
   cd build
   cmake ../ -Dnexus=1 -DBMWlibs=1 -DCMAKE_INSTALL_PREFIX=$ROOTSYS 
   cmake --build ./ --clean-first
   make install                              (as superuser -- maybe)
   /sbin/ldconfig                            (as superuser)

In the optimal case, everything is set up ;-)
