Installation

Windows

Download the latest Windows build from GitHub Releases. Extract the ZIP archive and run dinox.exe.

⚠ Important: The DinoX Windows executable is currently undergoing the official Microsoft code signing process for Windows 10/11. Once completed, DinoX will launch without any SmartScreen warnings. Until then, Windows SmartScreen may show a warning — click "More info" → "Run anyway" to proceed. You can verify the download integrity using the .sha256 checksum file.

Flatpak

Download from GitHub Releases

# 1. Install the GNOME runtime (required, one-time setup)
flatpak install flathub org.gnome.Platform//48

# 2. Install DinoX (replace ARCH with x86_64 or aarch64)
flatpak install --user dinox-*-ARCH.flatpak

# 3. Run
flatpak run im.github.rallep71.DinoX

AppImage

Build from Source

git clone https://github.com/rallep71/dinox.git
cd dinox
meson setup build
ninja -C build
./build/main/dinox

Dependencies (Debian/Ubuntu):

sudo apt install build-essential meson ninja-build valac \
  libgtk-4-dev libadwaita-1-dev libglib2.0-dev libgee-0.8-dev \
  libsqlcipher-dev libsecret-1-dev libicu-dev libdbusmenu-glib-dev libgcrypt20-dev \
  libgpgme-dev libqrencode-dev libsoup-3.0-dev libgstreamer1.0-dev \
  libgstreamer-plugins-base1.0-dev libgstreamer-plugins-bad1.0-dev \
  libnice-dev libgnutls28-dev libsrtp2-dev \
  gstreamer1.0-plugins-good gstreamer1.0-pipewire cmake wget

Required custom dependencies (not available in distro packages or too old):

DinoX requires SQLCipher with FTS5 (for optimal search), webrtc-audio-processing >= 2.1, libnice >= 0.1.23 and libomemo-c which are not available in Ubuntu 24.04 repos. Build them first:

# Build script does all four automatically:
./scripts/ci-build-deps.sh

# Verify FTS5 support:
sqlcipher :memory: "PRAGMA compile_options;" 2>/dev/null | grep FTS5

Or manually:

# webrtc-audio-processing v2.1 (echo cancellation, noise suppression)
wget -O webrtc-v2.1.tar.gz "https://gitlab.freedesktop.org/pulseaudio/webrtc-audio-processing/-/archive/v2.1/webrtc-audio-processing-v2.1.tar.gz"
tar xf webrtc-v2.1.tar.gz && cd webrtc-audio-processing-v2.1
meson setup build --prefix=/usr && ninja -C build && sudo ninja -C build install && sudo ldconfig
cd ..

# libnice 0.1.23 (ICE for audio/video calls)
wget -O libnice-0.1.23.tar.gz "https://gitlab.freedesktop.org/libnice/libnice/-/archive/0.1.23/libnice-0.1.23.tar.gz"
tar xf libnice-0.1.23.tar.gz && cd libnice-0.1.23
meson setup build --prefix=/usr -Dtests=disabled -Dgtk_doc=disabled && ninja -C build && sudo ninja -C build install && sudo ldconfig
cd ..

# libomemo-c (OMEMO encryption)
git clone https://github.com/rallep71/libomemo-c.git && cd libomemo-c
mkdir build && cd build && cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_POSITION_INDEPENDENT_CODE=ON ..
make -j$(nproc) && sudo make install && sudo ldconfig
cd ../..

For a complete, up-to-date build guide (including Fedora/Arch and call stack notes), see BUILD.md.

Local data encryption

DinoX stores your local data (accounts, messages, settings, cached metadata) in an encrypted SQLCipher database.

• You will be prompted for a password on startup.
• If you forget the password, the database cannot be recovered.
• A Panic Wipe action is available via the app menu and the shortcut Ctrl+Shift+Alt+P.

Audio/Video calling notes

DinoX 1:1 calling focuses on cross-client interoperability (notably with Conversations (Android) and Monal (iOS)) while keeping the existing media stack:

• Media stack: GStreamer (RTP/rtpbin + WebRTC elements), libnice (ICE), gnutls (DTLS), libsrtp2 (SRTP).
• PipeWire Support: DinoX integrates explicitly with PipeWire for modern audio support.

  Important: If your system uses PipeWire (common on Fedora, Manjaro, Mint 22+), you must install the GStreamer PipeWire plugin (usually gstreamer1.0-pipewire or gst-plugin-pipewire). This is a separate package from standard GStreamer plugins! Without it, calls or voice notes will fallback to the legacy sound server (Pulse/ALSA), which may lead to stability issues or incorrect device selection.

• Security profile: DTLS-SRTP only (no SDES-SRTP).
• Baseline codecs: Opus (audio) and VP8 (video) for reliable interop.
• Optional audio quality: webrtc-audio-processing enables AEC/NS/AGC if present.

  Note: Many distributions ship outdated versions. For best quality (Echo Cancellation), we strongly recommend building version 2.1+ from source. See BUILD.md.

If you are building from source using distro packages, ensure you are on a sufficiently new libnice (recommended: >= 0.1.23). For collecting reproducible call logs, see DEBUG.md.
