## Prerequisite
|
|
|
|
### Tutorial document
|
|
|
|
This tutorial is about gtk4 libraries.
|
|
It is originally used on Linux with C compiler, but now it is used more widely, on windows and macOS, with Vala, python 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, Debian and so on.
|
|
- Gcc
|
|
- Gtk4. Gtk included Linux distributions is version three at present.
|
|
You need to install gtk4 to your computer.
|
|
Refer to [gtk4 gitlab repository](https://gitlab.gnome.org/GNOME/gtk).
|
|
However, it might make some trouble like, for example, your pc doesn't recognize usb port
|
|
if you install them to `/usr/local`.
|
|
Therefore, I strongly recommend you not to install gtk4 to `/usr/local` on the computer you usually use.
|
|
Instead,
|
|
|
|
- Install it to another computer only used to try gtk4.
|
|
- Install it to your home directory, for example `$HOME/local`, in order to separate gtk4 from your system.
|
|
|
|
The second choice will be explained in [Section 3](sec3.src.md).
|
|
|
|
### Software
|
|
|
|
This repository includes ruby programs.
|
|
They are used to generate markdown files, html files, latex files and a pdf file.
|
|
|
|
You need:
|
|
|
|
- Linux distribution like Ubuntu.
|
|
- Ruby programming language.
|
|
There are two ways to install it.
|
|
One is install 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.
|
|
It is a gem, which is a library written in ruby.
|
|
You can install it as a package of your distribution or use gem command.
