## Prerequisite
|
|
|
|
### GTK 4 on a Linux OS
|
|
|
|
This tutorial describes GTK 4 libraries.
|
|
It is originally used on Linux with C compiler, but now it is used more widely, on Windows and MacOS, with Vala, Python, Ruby and so on.
|
|
However, this tutorial describes only *C programs on Linux*.
|
|
|
|
If you want to try the examples in the tutorial, you need:
|
|
|
|
- PC with Linux distribution like Ubuntu or Debian.
|
|
- GCC.
|
|
- GTK 4 (version 4.10.1 or later).
|
|
|
|
The stable version of GTK is 4.10.1 at present (24/April/2023).
|
|
The version 4.10 adds some new classes and functions and makes some classes and functions deprecated.
|
|
Some example programs in this tutorial don't work on the older version.
|
|
|
|
### Ruby and rake for making the document
|
|
|
|
This repository includes Ruby programs.
|
|
They are used to make GFM (GitHub Flavoured Markdown) files, HTML files, Latex files and a PDF file.
|
|
|
|
You need:
|
|
|
|
- Linux.
|
|
- Ruby programming language.
|
|
There are two ways to install it.
|
|
One is installing the distribution's package.
|
|
The other is using rbenv and ruby-build.
|
|
If you want to use the latest version of ruby, use rbenv.
|
|
- Rake.
