Thank you all for your answers.

The site of Fortran-lang is a good place to start.
Building program

Fortran dependencies are usually distributed as source code. Problem is that intermediate mod files and static libraries are compiler specific (sometimes even version specific). If you are lucky the dependencies are available as fpm packages. It’s both a build system and a package manager that will make your life easier: fpm . Just get familiar with the toml manifest and voilà.

This really helped. The process of compiling is clearer to me now, which doesn’t mean that I think it is easy at all.

fpm, is our build tool and a package manager, and is great too (although I am biased). It is meant to be an easy to use alternative to what currently exists. Integrating with fpm other projects is basically trivial, you can have a look at the Tutorials in the fpm documentation page for more

Tutorials — Fortran Package Manager

I started reading the tutorial about the FPM. I still have some questions:

1. All the ‘hard work’ to build a programme is replaced and concentrated in the fpm.toml file, isn’t it?

2. Still, I am not sure if I got it: In the example in which stdlib is included in the dependencies table, is the FPM expected to ‘search’ for the stdlib package in a sort of standard or default package repository, or is it instead going to search for stdlib somewhere in my hard drive??

3. Just to be sure: Creating a new project with fpm new “creates a git repository with a dummy project in the fpm standard layout” (see here). This doesn’t mean that I have to use GIT, right? I guess that it is just the standard layout that GIT would need, in case I used GIT.

4. I read that the FPM is still a work in progress. What risks or disadvantages can I expect if I decide to use it? I am planing to use packages related to

   1. reading from and writing into TXT files,
   2. creating and working with (sparse) matrices,
   3. integrating (one-variable) functions (with maybe one of the limits being ±infinity),
   4. nonlinear optimisation (both with and without derivatives), and
   5. working with probability distributions (calculating probabilities).

I am really looking forward to your answers. THANK YOU in advance!!
