REQUIREMENTS

A patched openFrameworks until my patches are merged into the official develop branch. For now it is recommended to use openframeworks-v0.7.4-stable.

• git clone -b openframeworks-v0.7.4-stable https://github.com/falcon4ever/openFrameworks.git

The current version is build using the following Native SDKs:

BlackBerry PlayBook

To compile the project you will need to install the BlackBerry Native SDK ( 2.1.0-1032 ):

• http://developer.blackberry.com/native/download/#playbook

BlackBerry 10

To compile the project you will need to install the BlackBerry 10 Native SDK ( 10.3.1.995 ):

• http://developer.blackberry.com/native/download/#blackberry10

QUICK START

Download (a patched) openFrameworks from the repository that is listed above. Next download this add-on and place it in the addons directory.

Workspace setup

Copy the example projects from

• "openFrameworks\addons\ofxQNX\examples\BB10" or "openFrameworks\addons\ofxQNX\examples\PlayBook"

to

• "openFrameworks\examples\qnx"

Launch the IDE provided by the BlackBerry Native SDK and create a new workspace at:

• "openFrameworks\examples\qnx"

After the IDE is running, import the following projects:

• "openFrameworks\libs"
• "openFrameworks\addons"

And all examples from

• "openFrameworks\examples\qnx"

Build and run

If you installed both the PlayBook and BB10 Native SDK, make sure your workspace has been set to the right platform.

To check

1. Project > Properties > QNX 2. Make sure that the SDK Selection is showing the correct platform

Build and Run

1. Click any of the example projects on the left 2. Right click, and click on Build Project 3. After it is done, right click on the project and choose Run As > BlackBerry [platform name] Application

BUILDING THE DEPENDENCIES (from scratch)

Since it is a bit complicated to build the required dependencies, I have included binaries that are needed to build the openFrameworks "emptyExample" and placed them in "ofxQNX\libs" (For Device-Release (ARMv7), Device-Debug (ARMv7) and Simulator-Debug (X86)).

If you still want to build these dependencies yourself (or update the libs), check out the scripts in the bootstrap directory.

• Copy paths.make.default to paths.make and fill out the paths to the SDKs
• The shell scripts in this directory will download and build the required libs.

Windows / Linux / Mac?

While I am only testing this port on Windows, its easier to compile the dependencies for the QNX platform on a Linux machine. I recommend using a virtual machine (e.g. VirtualBox) with Ubuntu installed on it (and using the Linux version of the Native SDK).

Setup the build environment

Boost

• http://www.boost.org/
• Included version is 1.52.0
• Required because std::tr1::shared_ptr and std::tr1::weak_ptr are not available from the Native SDK (#include <boost/tr1/memory.hpp>)
• The included version has been stripped down for use with openFrameworks.

FreeImage

• http://freeimage.sourceforge.net/
• Using version 3.14.1 and removed support for EXR to make it compile.
• Modify the makefiles (MKDIR and CP command) if you're not using MinGW but Linux or Mac
• Please note that this version of FreeImage is bundled with libpng14 (BB10 Native SDK 10.2.x+ now ships with both libpng14 and libpng16 (default))

GLU

• Since no GLU is included with the Native SDK I am using the one from:
• http://code.google.com/p/glues/
• Included version is 1.3

Tess 2

• I am using the source files from "openFrameworks\libs\tess2\Sources"
• In tesselator.h you will need to add: || defined(QNX) to make sure it will select: typedef unsigned short TESSindex;

Poco

• http://pocoproject.org/
• Version 1.4.3p1
• This can only be build on a Linux or Mac machine. Windows is not supported.
• Included a dummy syslog.h implementation (borrowed from the Android NDK) as it will not build without.
• Uses the included header files from openFrameworks 0.7.4

SDL

• Add PLAYBOOK to your project if you use Audio/SDL
• https://github.com/blackberry/SDL

TouchControlOverlay

• https://github.com/blackberry/TouchControlOverlay

Ogg/Vorbis

• https://github.com/blackberry/OggVorbis
• Build Vorbis with -fPIC

FAQ

Is ofxQNX stable enough for prime time?

• Yes, Definitely! It's currently being used in NodeBeat and Super Hexagon.

Where do I store my files?

Private assets that are read only

• Example: You've added a "data" folder as asset with "readonly.jpg" in it:
• ofToDataPath("app/native/data/readonly.jpg");

Private data is read/write from app (sandboxed):

• Example: settings.dat
• ofToDataPath("data/settings.dat");

Public data (requires <permission>access_shared</permission> in the bar descriptor file)

• Example: screenshot.jpg
• ofToDataPath("shared/camera/screenshot.jpg");

More info:

• accessible_folders

TODO

• Update FreeImage and make the project use libpng16 instead of libpng14
• Add Camera support for BB10.
• Add GPS support and example.
• Clean up ofxQNXSoundPlayer and qnxAudioOutputExample class.
• Remove SDL dependency (only used for ofSoundStream / qnxAudioOutputExample) and use the QSA audio system directly.
• Figure out why loading OGG files is painfully slow.

BUGS?

• Please report bugs and submit fixes on github ;)
