Install


›Requirements

The following libraries/programs are required: 

  • Cmake 2.6.3+
  • GSL


The following libraries are optional: 

  • CGAL 3.7+ (for delaunay)
  • CFitsIO (for reading FITS)
  • SDL/SDL-image (for loading jpg,bmp,...)
  • mathGL 1.10 (for visualizing persistence diagrams with pdview)
  • -> A compatible version of the library is included in the 'external/'
  • directory starting from disperse v0.9.22
  • Qt4 (for visualizing persistence diagrams with pdview)


NOTE: gcc v4.3.3+ is required for multithreading to be enabled.


›Compiling

Go to the ${DISPERSE_SRC}/build directory and type:
 
cmake ../

This will check the configuration and generate the Makefile. Read the output to know which library were found, which were not, and how to specify their path (option -DLIBNAME_DIR=path/to/library/ where {LIBNAME} may be QT,GSL,SDL,MATHGL or CGAL).
The default install path is "${DISPERSE_SRC}", but it can be changed using option -DCMAKE_INSTALL_PREFIX=PATH/TO/INSTALL/DIR.
Then just compile and install with:

make install -j N

where N is the number of processors to be used for compilation. One to seven executables should be created in ${DISPERSE_SRC}/bin (or ${CMAKE_INSTALL_PREFIX}/bin if set), depending on which libraries were found:
