FreeBSD安装Fortran
1. 说明
FreeBSD 的 Fortran 编译器是 lfortran :
LFortran is a modern open-source (BSD licensed) interactive Fortran compiler built on top of LLVM. It can execute user’s code interactively to allow exploratory work (much like Python, MATLAB or Julia) as well as compile to binaries with the goal to run user’s code on modern architectures such as multi-core CPUs and GPUs.

第一个 helloworld.f90 程序的内容：
program hello_world
implicit none
write (*, *) 'Hello World!'
end program hello_world
用 lfortran 编译执行 helloworld.f90 ：
lfortran -o helloworld helloworld.f90 && ./helloworld
Hello World!
