Install freetype in Linux

FreeType is a popular open-source software development library that provides high-quality font rendering for applications. It is widely used across various platforms, including Linux. This tutorial will guide you through the process of installing FreeType on Linux.

Update your system:
Before installing FreeType, it is recommended to update your system packages to their latest versions. For Debian/Ubuntu-based distributions, run:
```
sudo apt update
sudo apt upgrade
```
For Fedora-based distributions, run:
```
sudo dnf update
```
For openSUSE-based distributions, run:
```
sudo zypper update
```
Install FreeType:
To install FreeType, use the package manager of your Linux distribution:
- For Debian/Ubuntu-based distributions, run:
```
sudo apt install libfreetype6 libfreetype6-dev
```
- For Fedora-based distributions, run:
```
sudo dnf install freetype freetype-devel
```
- For openSUSE-based distributions, run:
```
sudo zypper install freetype2 freetype2-devel
```
- For Arch Linux-based distributions, run:
```
sudo pacman -S freetype2
```
Verify the installation:
You can verify that FreeType has been installed successfully by checking its version:
```
freetype-config --version
```
This command should display the version number of the installed FreeType library.
Compile and link against FreeType:
To use FreeType in your C/C++ projects, you will need to include the FreeType header files and link against the FreeType library.
Add the following lines in your C/C++ source code:
```
#include <ft2build.h>
#include FT_FREETYPE_H
```
To compile your project, include the necessary linker flags provided by freetype-config. For example:
```
gcc my_project.c -o my_project $(freetype-config --cflags) $(freetype-config --libs)
```
Replace my_project.c with the name of your source file and my_project with the desired output binary name.

By following these steps, you can install the FreeType library on your Linux system and start using it in your applications for font rendering.
