First Program

Build the library according to the Getting Started guide.

Creating your first program

Create a program in Fortran 90 using the FPL module:

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

Save it as myfirstprogram.f90 and compile using gfortran:

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

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

info

-I<dir> specifies where to find .mod files for compiled modules. The directory corresponds to the MODDIR variable defined in the Makefile. See GNU Fortran Compiler Documentation for details.

Run the program:

./myfirstprogram.out
