# Installing on Mac OS X
|
||
|
||
## Supported platforms
|
||
|
||
* 10.6 (Snow Leopard)
|
||
* 10.7 (Lion)
|
||
* 10.8 (Mountain Lion)
|
||
* 10.9 (Mavericks)
|
||
* 10.10 (Yosemite)
|
||
* 10.11 (El Capitan)
|
||
|
||
## Prerequisites
|
||
|
||
To develop applications using the GStreamer SDK for OS X you will need
|
||
OS X Snow Leopard (10.6) or later and
|
||
[XCode 3.2.6](https://developer.apple.com/devcenter/mac/index.action) or
|
||
later.
|
||
|
||
The recommended system is [macOS Sierra](http://www.apple.com/macosx/) with
|
||
[XCode 8](https://developer.apple.com/xcode/)
|
||
|
||
## Download and install the SDK
|
||
|
||
There are 3 sets of files in the SDK:
|
||
|
||
- The runtime files are needed to run GStreamer applications. You
|
||
probably want to distribute these files with your application (or
|
||
the installer below).
|
||
- The development files are **additional** files you need to create
|
||
GStreamer applications.
|
||
- Mac OS X packages that you can use
|
||
with [PackageMaker](https://developer.apple.com/library/mac/#documentation/DeveloperTools/Conceptual/PackageMakerUserGuide/Introduction/Introduction.html)
|
||
to deploy GStreamer with your application
|
||
|
||
Get **both the runtime and the development installers** from
|
||
the [GStreamer download page](https://gstreamer.freedesktop.org/download/#macos)
|
||
and **please install both of them**:
|
||
- The runtime installer is e.g. `gstreamer-1.0-{VERSION}-x86_64.pkg`, and
|
||
- The development installer is e.g. `gstreamer-1.0-devel-{VERSION}-x86_64.pkg`
|
||
|
||
> 
|
||
> On Mac OS X 10.6 (Snow Leopard) you have to install Python 2.7 manually. It is included in later versions of OS X already. You can get it from [here](http://www.python.org/getit).
|
||
|
||
The downloads are
|
||
[Installer Packages
|
||
(.pkg)](http://en.wikipedia.org/wiki/Installer_%28Mac_OS_X%29).
|
||
|
||
Double click the package file and follow the instructions presented by
|
||
the install wizard. In case the system complains about the package not
|
||
being signed, you can control-click it and open to start the
|
||
installation. When you do this, it will warn you, but there is an option
|
||
to install anyway. Otherwise you can go to System Preferences → Security
|
||
and Privacy → General and select the option to allow installation of
|
||
packages from "anywhere".
|
||
|
||
|
||
These are some paths of the GStreamer framework that you might find
|
||
useful:
|
||
|
||
- /Library/Frameworks/GStreamer.framework/: Framework's root path
|
||
- /Library/Frameworks/GStreamer.framework/Versions: path with all the
|
||
versions of the framework
|
||
- /Library/Frameworks/GStreamer.framework/Versions/Current: link to
|
||
the current version of the framework
|
||
- /Library/Frameworks/GStreamer.framework/Headers: path with the
|
||
development headers
|
||
- /Library/Frameworks/GStreamer.framework/Commands: link to the
|
||
commands provided by the framework, such as gst-inspect-1.0 or
|
||
gst-launch-1.0
|
||
|
||
For more information on OS X Frameworks anatomy, you can consult the
|
||
following [link](https://developer.apple.com/library/mac/#documentation/MacOSX/Conceptual/BPFrameworks/Concepts/FrameworkAnatomy.html)
|
||
|
||
## Configure your development environment
|
||
|
||
### Building the tutorials
|
||
|
||
The tutorials code, along with project files and a solution file for
|
||
them all, are in the
|
||
[gst-docs](https://gitlab.freedesktop.org/gstreamer/gstreamer/-/tree/main/subprojects/gst-docs) in the
|
||
`examples/tutorials` subdirectory.
|
||
|
||
To start building the tutorials, create a new folder in your Documents
|
||
directory and copy the
|
||
folder `/Library/Frameworks/GStreamer.framework/Current/share/gst-sdk/tutorials`.
|
||
|
||
You can fire up XCode and load the project file.
|
||
|
||
Press the **Run** button to build and run the first tutorial. You can
|
||
switch the tutorial to build selecting one of the available schemes.
|
||
|
||
### Creating new projects
|
||
|
||
The GStreamer binaries provides a
|
||
[framework](https://developer.apple.com/library/mac/#documentation/MacOSX/Conceptual/BPFrameworks/Tasks/IncludingFrameworks.html)
|
||
that you can drag and drop to XCode to start using it, or using the
|
||
linker option ***-framework GStreamer****.*
|
||
|
||
There is a small exception to the regular use of frameworks, and you
|
||
will need to manually include the headers search
|
||
path `/Library/Frameworks/GStreamer.framework/Headers`
|
||
|
||
- XCode: Add the headers path to **Search Paths → Header Search
|
||
Paths**
|
||
- GCC: Using the compiler
|
||
option **-I/Library/Frameworks/GStreamer.framework/Headers**
