Mac OS X

µGFX can be run natively on a Mac OS X system. This simplifies the process of developing your embedded GUI application a lot.

The MacOS X port has been tested successfully on OS X 10.10 and 10.11.

Note: The performance of the resulting program is very bad unless you use the Linux Framebuffer driver. This is because the X driver just uses setPixel() and doesn't take any advantage of area blitting or double buffering. The application will run A LOT faster on the actual microcontroller.

Dependencies

Make sure you got the following things installed:

• clang (by installing Xcode)
• XQuartz

Makefile

Copy the makefile that can be found in /boards/base/OSX/example/ to your project directory. You need to set the OSX_SDK and OSX_ARCH variables.

OSX_SDK

The OSX_SDK variable needs to contain the path to the OS X SDK. The path can be found by executing xcodebuild -sdk -version in the terminal:

TecMac:osx joel.bodenmann$ xcodebuild -sdk -version
MacOSX10.11.sdk - OS X 10.11 (macosx10.11)
SDKVersion: 10.11
Path: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdkPlatformVersion: 1.1
PlatformPath: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform
ProductBuildVersion: 15E60
ProductCopyright: 1983-2016 Apple Inc.
ProductName: Mac OS X
ProductUserVisibleVersion: 10.11.4
ProductVersion: 10.11.4

In our case we set the OSX_SDK variable as follows:

OSX_SDK = /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk

OSX_ARCH

The OSX_ARCH variable is used to specify on which earliest/oldest version of MacOS X the executable will be able to run on. Usually it's enough to just set it to the version of OS X that you are running which you can find my executing sw_vers in a terminal:

TecMac:osx joel.bodenmann$ sw_vers 
ProductName:	Mac OS X
ProductVersion:	10.11.4BuildVersion:	15E65

In our case we are running OS X version 10.11:

OSX_ARCH = -mmacosx-version-min=10.11

For more information about the macosx-version-min option, please refer to the corresponding compiler documentation.
