# This Makefile can be used to build programs test_mcd_c and           #
# test_mcd_cpp, examples of C and C++ interfaces that use the fortran  #
# routines of the Mars Climate Database.                               #
# Before using it, you might have to change some of                    #
# the default definitions given below, namely:                         #
# - The path to your NetCDF installation directory (NETCDF_DIR)        #
# - The path to the fortran routines (call_mcd.F, julian.F and         #
#   heights.F) the interfaces will use (FROUTINES_DIR)                 #
# - The compiler names and options (FC, CC, CPP, FCOPT, CCOPT, CPPCOPT)#
# - The extra libraries (unfortunately extremely compiler dependent)   #
#   required to build the C end C++ interfaces (EXTRALIBS)             #
# See the user's guide for more information                            #
