*__Disclaimer__: I have no insight or familiarity with QPixel or any of the packages described below. These are just the variations that got me to a QPixel installation that was working well enough to display the Codidact homepage.*

## Installing QPixel on Fedora Linux without brew
If you happen to be installing in this situation, a few things might have different names. Here are some of the differences I had to allow for.

*This may or may not be similar for Red Hat and CentOS installations.*

### ImageMagick
> <p style="color:red">An error occurred while installing rmagick (4.2.6), and Bundler cannot continue.</p>

Instead of the recommended `libmagickwand-dev`, which is not available on Fedora, you can use `ImageMagick-devel`:

```text
dnf install ImageMagick-devel
```

I couldn't find an official guide to this but I stumbled upon the alternative name for the package in a [guide to Python bindings for ImageMagick](https://docs.wand-py.org/en/0.2.4/guide/install.html#install-imagemagick-redhat). That guide refers to `yum` instead of `dnf` as it's aimed at Red Hat, but it installed for me on Fedora using `dnf`.

### MySQL
> <p style="color:red">An error occurred while installing mysql2 (0.5.4), and Bundler cannot continue.</p>

Instead of the recommended `mysql-server`, which is not available on Fedora, you can use the community maintained `community-mysql-server`:

```text
dnf install community-mysql-server
systemctl enable mysqld
systemctl start mysqld
```

I found I also needed to install `mysql-devel`:

```text
dnf install mysql-devel
```

The [guide to installing MySQL on Fedora](https://docs.fedoraproject.org/en-US/quick-docs/installing-mysql-mariadb/#install-from-fedora-main-repo) also includes instructions for installing Oracle's package instead of the community maintained one if you prefer.

### libvips
`libvips` is not available under that name on Fedora, instead it is called `vips`:

```text
dnf install vips
```

### Redis
I discovered on the [Redis Fedora page](https://developer.fedoraproject.org/tech/database/redis/about.html) that `redis-server` is not available under that name on Fedora, instead it is called `redis`:

```text
dnf install redis
systemctl enable redis
systemctl start redis
```

This is not a security guide. Please use your own judgement on whether each command does or does not need to be entered with something like `sudo` or `su`. I am not qualified to tell you what is safe for your particular system.
