About This Page
++
This page is about ancient (before the year 2000) programming languages, like Fortran and C. This page is mostly + about showing how it was done before fancy build tools and syntax were a thing. It also serves a purpose of a + showing, with examples, how to not only set up the programming environments, but also the whole workflow from + prototype to production.
++ +
This whole idea started when I made my first "serious" blog, rbwr.dk, but it didn't + feel like quite the "correct" place to put it. So the idea was shelved for a time... Until recently, when I picked + up a project in Fortran. Yep, Fortran. I had gotten bored, and wanted to challenge myself. And I thought, that if + I'm going to learn the language, I might as well put blood, sweat and tears into formulating and showcasing how + it's done (correctly).
++ +
I did initially want to try COBOL, but after looking at some examples, Fortran kind of looked more appealing lol.

My name is Rasmus Rasmussen (yes, that's my name), I live somewhere in the outskirts of Odense, Denmark, and I'm primarily a backend developer. But lately, I've started to like developing in vue3. With TypeScript, of cause. It's a nice chance of pace, and I often find myself wanting to experiment with different styling, as well as trying to optimize and minimize my bundles.

+ Setting Up The Environment
+
+
+
+ If you're familiar with C, then you would feel right at home with Fortran's build environment. There isn't really
+ an "official" compiler for the language, only a standard, that has to be implemented by the compilers. But there
+ are a lot of great compilers, that might as well be "official."
+
+
+ The top listed compiler on Fortran's website, is the GNU Fortran compiler (gfortran). It's the one I will be using
+ throughout the examples on the site. Unless stated otherwise. There are also some other notable compilers, that
+ has some rather interesting qualities to them.
+
+
+ Compilers:
+
+ - lfortran (This one can be used as an interactive
+ compiler, and also supports parsing all of the 2018 standard syntax. It can also compile Fortran to WebAssemply).
+ - NVIDIA HPC SDK (This one comes with a whole lot of GPU
+ accelerated libraries).
+
+
+
+ But , we will use gfortran. I will mainly be focusing on installing and developing on Linux.
+
+
+ First, we install the compiler.
+
+
+ For Fedora.
+ $ sudo dnf install gcc-gfortran
+
+
+
+ For ubuntu.
+ $ sudo apt install gfortran
+
+
+
+ And that's it. Pretty easy.
+
+
+ Project Structure
+
+
+
+ When creating a Fortran project, or any project in general, you want a structure. There is a lot of different
+ layouts for the structure, but equal amongst them, is the src folder. That's where we keep all of out
+ source code. Like *.f90, *.f95 files.
+
+
+ But other than that, most projects include a Makefile file, a library, test
+ and bin folder. Your layout doesn't need to look like this specifically, nor does it have to contain
+ the same folders. Each project is different, and so are the requirements. But this layout is simple, and great
+ for medium to large projects.
+
+
+ But if we're doing micro-projects, as in like, a hello world application, a test application, or a small tool,
+ this layout is rather redundant, and on the examples on the website here, we will only use it on bigger projects,
+ and we will let you know, when or how we set up the project.
+
+
+
+

+
+
+
+ Makefiles are very useful, and becomes increasingly useful, the bigger the project is.
