Dependencies
HTML Overlay has the following dependencies for building from source:
- OpenGL. See more about OpenGL in this link: OpenGL
- GTK+. You can see more about GTK+ in this link: GTK+.
- Webkit2GTK+. You can see more about it in the following link: Webkit2GTK+
- GLEW
- EGL
- GLFW (optional)
In the following sections you can see how to install, in Debian-based systems, the dependencies mentioned before.
OpenGL
To install OpenGL, please use:
sudo apt install mesa-utils sudo apt-get install freeglut3
GTK+
To install GTK+,please use:
sudo apt-get install build-essential libgtk-3-dev
Webkit2GTK+
To install Webkit2GTK+, please use:
sudo apt-get install libwebkit2gtk-4.0-dev
GLEW
To install GLEW, please use:
sudo apt-get install libglew-dev
GLFW
To install GLFW, please use:
sudo apt-get install libglfw3 libglfw3-dev
Custom v4l2src element
To capture from a camera in raw format with a bits per pixel different from 0, you may require to recompile the GStreamer Plugins Good. Please, follow these steps.
Documentation (optional)
For the documentation, consider the following dependency:
- doxygen
Please, install it using (in Debian-based systems):
sudo apt install -y \ doxygen \
Meson building system
At the building system level:
- ninja-build
- python3-pip
- pkg-config
- meson
Please, install them using (in Debian-based systems):
sudo apt install -y \ python3 \ python3-pip \ ninja-build \ pkg-config
The process should be similar in other systems, not based on Debian.
Building the project
Once fulfilled the dependencies, you can run a default compilation with:
meson build --optimization 3 --prefix /usr -Denable-docs=disabled -Ddeveloper-mode=false ninja -C build sudo ninja -C build install
For additional customization, you may refer to the following table of options:
Configure Option | Description |
---|---|
-Ddeveloper-mode=false | Disable developer mode. Enabled by default. |
-Denable-docs=disabled | Skip documentation generation. Enabled by default. |
-Denable-gst=disabled | Skip building for GStreamer elements. Enabled by default. |
-Denable-tests=disabled | Skip building tests. Enabled by default. |
--prefix /usr | Set the installation path of the library. |
--optimization 3 | Set the optimization level to the maximum |
