Category:How to - Fortran

GCC contains gfortran as part of it(usually) but the library does not get pulled in. or you can install gfortran separately.

To ensure its installed (or include the packages in your image recipe)

opkg update
opkg install gfortran
opkg install gfortran-symlinks
opkg install libgfortran
opkg install libgfortran-dev

Then

vim hello.f90

! hello.f90
program hello
implicit none
print*, " "
print*, "Hello World!"
print*, " "
end

To compile

user@overo:~# gfortran -o hellof hello.f90

to run

user@overo:~# ./hellof 
 
Hello Fortran World!
 
user@overo:~#
