Installing Gadget

  • Download gadget from here.

  • Make sure you have MPI, GSL, HDF5 and FFTW 2 installed. All but FFTW 2 can be easily installed and managed with spack and modules. For FFTW 2, have a look at the instructions here.

  • Make sure you have all these modules loaded correctly if you’re using lmod.

  • Navigate to the Gadget2 directory (should contain a Makefile). If necessary, modify compilation flags and library paths. Mine look like this:

CC       =  mpicc
OPTIMIZE =  -Wall -g -O3
GSL_INCL =  -I/$(GSL_ROOT)/include
GSL_LIBS =  -L/$(GSL_ROOT)/lib
FFTW_INCL=  -I/$(FFTW_ROOT)/include
FFTW_LIBS=  -L/$(FFTW_ROOT)/lib
HDF5INCL =  -I/$(HDF5_ROOT)/include
HDF5LIB  =  -L/$(HDF5_ROOT)/lib  -lhdf5 -lz
MPICHLIB =

  • run make
