## Releases

### Linux

For developement, or if none of the release options are satisfying, 
see [manual installation](#manual-installation).

#### AppImage

For **x86 64bit glibc-based systems**, Mirage is available as an AppImage
on the [release page](https://github.com/mirukana/mirage/releases).

AppImages are single executable files that contain the app and all 
its dependencies.  
Mirage images are built in Ubuntu 16.04, and should therefore run on any distro
released in April 2016 or later.

[How to start AppImages](https://docs.appimage.org/introduction/quickstart.html#how-to-run-an-appimage)
(TL;DR: `chmod +x Mirage-*.AppImage && ./Mirage-*.AppImage`)

#### Flatpak

For **other architectures or musl-based systems**, Mirage is also available
as a Flatpak
on the [release page](https://github.com/mirukana/mirage/releases).

To install and run it:

```sh
    flatpak install --user flathub org.kde.Platform//5.12 mirage-*.flatpak
    flatpak run io.github.mirukana.mirage
```

If the download fails for some reason, run `flatpak repair` before retrying.

If your architecture is not listed on the release page, clone the repository
and see [packaging/flatpak/README.md](packaging/flatpak/README.md) to build the
package on your machine.

## Manual Installation

**Qt 5.12+**, **Python 3.6+** (with **pip** to install packages from the
[requirements.txt](requirements.txt)), **PyOtherSide 1.5+** and
**libolm 3+** are required.  
The equivalent `-dev` or `-devel` packages are needed, if your distro
splits development headers into their own packages.

For the Pillow Python package, these dependencies are recommended to support 
all common image formats:

- **libjpeg-turbo**
- **zlib**
- **libtiff**
- **libwebp**
- **openjpeg2**

**libmediainfo** is also required for the pymediainfo package.

### Environment Variables

To ensure Qt **5** will be used by default, compile using all CPU cores and 
optimize the build for your machine:

```sh
export QT_SELECT=5
export MAKEFLAGS="-j$(nproc)"
export CFLAGS="-march=native -O2 -pipe"
```

### Package Manager Dependencies

#### Alpine Linux 3.9+ / apk

[PyOtherSide](#installing-pyotherside-manually) and 
[libolm](#installing-libolm-manually) must be manually installed.

```sh
sudo apk add qt5-qtquickcontrols2-dev qt5-qtsvg-dev qt5-qtimageformats \
             python3-dev py3-setuptools \
             build-base git cmake \
             libjpeg-turbo-dev zlib-dev tiff-dev libwebp-dev openjpeg-dev \
             libmediainfo-dev

export PATH="/usr/lib/qt5/bin:$PATH"
```

#### Arch Linux / pacman & AUR

**libolm** is from the AUR, this example uses
[yay](https://github.com/Jguer/yay) to install it like other packages.  
Alternatively, you can just use `pacman` and
[install libolm manually](#installing-libolm-manually).

```sh
yay -Syu qt5-base qt5-declarative qt5-quickcontrols2 qt5-svg \
         qt5-graphicaleffects qt5-imageformats \
         python python-pip \
         python-pyotherside \
         libolm \
         base-devel git cmake \
         libjpeg-turbo zlib libtiff libwebp openjpeg2 libmediainfo
```

#### Fedora 30+ / dnf

[PyOtherSide](#installing-pyotherside-manually) and 
[libolm](#installing-libolm-manually) must be manually installed.

```sh
sudo dnf groupinstall 'Development Tools'
sudo dnf install qt5-devel qt5-qtbase qt5-qtdeclarative qt5-qtquickcontrols2 \
                 qt5-qtsvg qt5-qtgraphicaleffects qt5-qtimageformats \
                 python3-devel python3-pip \
                 git cmake \
                 libjpeg-turbo-devel zlib-devel libtiff-devel libwebp-devel	\
                 openjpeg2-devel libmediainfo-devel

sudo ln -s /usr/bin/qmake-qt5 /usr/bin/qmake
```

#### Gentoo / emerge

[libolm](#installing-libolm-manually) must be manually installed.

You might need to prepend the `emerge` command with `USE=bindist`,
if `emerge` says so.

```sh
sudo emerge -av qtcore qtdeclarative qtquickcontrols2 \
                qtsvg qtgraphicaleffects qtimageformats \
                dev-python/pip pyotherside \
                dev-vcs/git cmake \
                libjpeg-turbo zlib tiff libwebp openjpeg libmediainfo
```

#### Ubuntu 19.04 / apt

[libolm](#installing-libolm-manually) must be manually installed.


```sh
sudo apt update
sudo apt install qt5-default qt5-qmake qt5-image-formats-plugins \
                 qml-module-qtquick2 qml-module-qtquick-window2 \
                 qml-module-qtquick-layouts qml-module-qtquick-dialogs \
                 qml-module-qt-labs-platform \
                 qtdeclarative5-dev \
                 qtquickcontrols2-5-dev \
                 python3-dev python3-pip \
                 qml-module:io-thp-pyotherside \
                 build-essential git cmake \
                 libjpeg-turbo8-dev zlib1g-dev libtiff5-dev libwebp-dev \
                 libopenjp2-7-dev libmediainfo-dev
```

#### Ubuntu 19.10+, Debian bullseye / apt

Follow the steps for [Ubuntu 19.04](#ubuntu-1904--apt), but instead of
installing libolm manually:

```sh
sudo apt install libolm-dev
```

#### Void Linux / xbps

[PyOtherSide](#installing-pyotherside-manually) must be manually installed.

```sh
sudo xbps-install -Su qt5-devel qt5-declarative-devel \
                      qt5-quickcontrols2-devel \
                      qt5-svg-devel qt5-graphicaleffects qt5-imageformats \
                      python3-devel python3-pip \
                      olm-devel \
                      base-devel git cmake \
                      libjpeg-turbo-devel zlib-devel tiff-devel libwebp-devel \
                      libopenjpeg2-devel libmediainfo-devel
```

### Installing PyOtherSide Manually

Skip this section if you already installed it from your
distro's package manager.

```sh
git clone https://github.com/thp/pyotherside
cd pyotherside
make clean
qmake
make
sudo make install
```

### Installing libolm Manually

Skip this section if you already installed it from your
distro's package manager.

```sh
git clone https://gitlab.matrix.org/matrix-org/olm/
cd olm
cmake . -Bbuild
cmake --build build
sudo make install
```


### Installing Mirage

After following the above sections instructions depending on your system,
clone the repository, install the python dependencies, compile and install:

```sh
git clone --recursive https://github.com/mirukana/mirage
cd mirage
pip3 install --user -Ur requirements.txt
pip3 install --user -U uvloop==0.14.0

qmake mirage.pro
make
sudo make install
```

`uvloop` brings performance improvements, but can be skipped 
if you have trouble installing it.

If everything went fine, run `mirage` to start.


### Common Issues

#### cffi version mismatch

When installing the python dependencies, if you get a version mismatch error
related to `cffi`, try:

```sh
pip3 install --user --upgrade --force-reinstall cffi
```

#### Component is not ready

If the application doesn't start when you run `mirage` and shows a 
`QQmlComponent: Component is not ready` message in the terminal,
a QML component failed to import due to either missing dependencies
or a programming error.

If PyOtherSide is correctly installed, you should see a similar message:

    Got library name:  "/usr/lib/qt5/qml/io/thp/pyotherside/libpyothersideplugin.so"

If not, verify the installed files and their permissions. 
To ensure the correct permissions are set for the PyOtherSide plugin files:

    sudo chmod -R 755 /usr/lib/qt5/qml/io
    sudo chmod 644 /usr/lib/qt5/qml/io/thp/pyotherside/*
    sudo chmod 755 /usr/lib/qt5/qml/io/thp/pyotherside/*.so

Note that the Qt lib path might be `/usr/lib/qt/` instead of `/usr/lib/qt5/`,
depending on the distro.
