How to Start

Build the library according to Build Library.

First program

Create a program in fortran 90 standard using the FPL module.

program myfirstprogram
  use fpl !FPL module
  implicit none
  write(*,*) "This is my first program using " fpl_libversion()
end program myfirstprogram

Save as file (myfirstprogram.f90) and compiling using gfortran.

#RedHat based systems
gfortran -o myfirstprogram.out myfirstprogram.f90 -I/usr/lib64/gfortran/modules/ -lFPL

#Debian based systems
gfortran -o myfirstprogram.out myfirstprogram.f90 -I/usr/include/ -lFPL

Important

-I<dir> This option specifies where to put .mod files for compiled modules. It is also added to the list of directories to Influencing the linking step. See the GNU Fortran Compiler Documentation .

<dir> is defined in Makefile as $(FPL_moddir). See Build Library.

After compilation run the program ./myfirstprogram.out
