Set up OpenGL Utility Toolkit (GLUT) and Codeblocks on Linux

Didik Supriadi — Mon, 27 Jan 2020 17:54:46 +0000

Before we continue, let’s discuss something about GLUT and Codeblocks.

Here we use FreeGLUT instead of the original GLUT written by Mark Kilgard. FreeGLUT is an open source alternative to the OpenGL Utility Toolkit (GLUT) library with a free software license. FreeGLUT allows us to create and manage windows containing OpenGL contexts on a wide range of platforms and also read the mouse, keyboard, and joystick functions.

Codeblocks is a free C++ IDE that is extensible and configurable. Codeblocks can be extended with plug-in DLLs and even you can compile your own plug-ins.

Before we begin to set up, let’s prepare some packages that need to be installed beforehand.

Install Codeblocks

On Fedora

sudo dnf install codeblocks

On Ubuntu

sudo apt install codeblocks

Install FreeGLUT

On Fedora

sudo dnf install freeglut-devel

On Ubuntu

sudo apt install freeglut3-dev

Set up GLUT in Codeblocks

Open Codeblocks
Go to Settings -> Global variables…
Under Current variable , click New and create glut variable
Fill in each field as shown below, and click Close when finish
- On Ubuntu
- On Fedora

Let’s try to create a new project

Open the project wizard
Create a “HelloWorld” Project
Use glut global variable
Leave the default compiler configuration as it is and then click Finish
A demo project will be created as shown in below
Run the demo project, and we’ll see this wonderful objects

Packaging nanime in Fedora COPR

Didik Supriadi — Thu, 16 Jan 2020 08:59:37 +0000

Over the last summer of 2015, I’ve been watching anime as an enjoyable entertainment. To watch anime, it forces me to watch video by streaming “on browser”. I found it is very annoying since video player provided by video streaming services is very awful.

Recently, I created nanime. I named it “nanime” because it currently only serves anime links from nanime.yt and since there are no other programs using it. This program will fetch videos of each anime episodes, provided the anime URL from nanime.yt is given.

In this article, I’ll cover and share how I…

Created the RPM SPEC file
Built the package in COPR
Found mistakes

Creating RPM SPEC file

I read about rpm packaging in Fedora Packaging Guidelines. It’s a good guide, though I end up reading rpm-packaging-guide since it has PDF version. The reason is only because I have my phone everywhere so that I can easily read PDF without opening my browser.

Since nanime is implemented with bash, I can easily implement the SPEC file. Anyway, it’s a very simple application at the first place.

Building package

First, I create the source package from SPEC file

rpmbuild -bs ~/rpmbuild/SPECS/nanime.spec

And then, I create the binary package

rpmbuild -bb ~/rpmbuild/SPECS/nanime.spec

Actually, I can also create both of them simultaneously

rpmbuild -ba ~/rpmbuild/SPECS/nanime.spec

Lastly, I can build my package in COPR service

copr-cli build nanime ~/rpmbuild/SRPMS/nanime-0.1-1.fc31.src.rpm

Finding mistakes

Fixing bugs

I didn’t test my code thoroughly before building the project in COPR causing a very hurtful slap on my face.

Signing package

Even though adding GPG sign to a package is not a must, It’s a good thing to do and nothing to lose anyway. rpm-packaging-guide also gives a good case where Signed-package is very useful.

Starting to write articles

Didik Supriadi — Tue, 07 Jan 2020 12:14:17 +0000

I’ve been spending my time reading articles lately. I love reading them because they are written by people who cares about sharing. The more I read those articles, it builds my interest to write my own version, my original story.

And that’s where I decide to create this site. I would like to share some experiences that I have been through, also some knowledge that I learn, and maybe some arbitrary thought to ponder. it’s all for the sake of my wish to tell all my experiences to the world.
