forcing users to use osgDB::readRef*File() methods. The later is preferable as it closes a potential threading bug when using paging databases in conjunction
with the osgDB::Registry Object Cache. This threading bug occurs when one thread gets an object from the Cache via an osgDB::read*File() call where only
a pointer to the object is passed back, so taking a reference to the object is delayed till it gets reassigned to a ref_ptr<>, but at the same time another
thread calls a flush of the Object Cache deleting this object as it's referenceCount is now zero. Using osgDB::readREf*File() makes sure the a ref_ptr<> is
passed back and the referenceCount never goes to zero.
To ensure the OSG builds when OSG_PROVIDE_READFILE is to OFF the many cases of osgDB::read*File() usage had to be replaced with a ref_ptr<> osgDB::readRef*File()
usage. The avoid this change causing lots of other client code to be rewritten to handle the use of ref_ptr<> in place of C pointer I introduced a serious of
templte methods in various class to adapt ref_ptr<> to the underly C pointer to be passed to old OSG API's, example of this is found in include/osg/Group:
bool addChild(Node* child); // old method which can only be used with a Node*
tempalte<class T> bool addChild(const osg::ref_ptr<T>& child) { return addChild(child.get()); } // adapter template method
These changes together cover 149 modified files, so it's a large submission. This extent of changes are warrent to make use of the Object Cache
and multi-threaded loaded more robust.

There are two problems: first, module names are spelled incorrectly in root

for them are e.g. GSTREAMER_GSTREAMER-APP_INCLUDE_DIRS instead of
GSTREAMER_APP_INCLUDE_DIRS.
Second, gstreamer base component is detected as GSTREAMER while checked
later as GSTREAMER_BASE. I've uncommented the detection as
GSTREAMER_BASE, but obviously that should be revisited and only one
detection left. With this patch, gstreamer is detected properly and
the plugins is successfully built and installed."

The mac os sdk version is recognized by the current CMAKE script as 10.1 instead of 10.10 since it cuts the version string from the 4th place. I introduced a more reliable version checking based on splitting the returned version code into MAJOR MINOR and PATCH parts and reassemble the OSG sdk version afterwards.
I replaced the existing CMake code against the following (returning now version 10.10 as expected):
# Determine the canonical name of the selected Platform SDK
EXECUTE_PROCESS(COMMAND "/usr/bin/sw_vers" "-productVersion"
OUTPUT_VARIABLE OSG_OSX_SDK_NAME
OUTPUT_STRIP_TRAILING_WHITESPACE)
STRING(REPLACE "." ";" MACOS_VERSION_LIST ${OSG_OSX_SDK_NAME})
LIST(GET MACOS_VERSION_LIST 0 MACOS_VERSION_MAJOR)
LIST(GET MACOS_VERSION_LIST 1 MACOS_VERSION_MINOR)
LIST(GET MACOS_VERSION_LIST 2 MACOS_VERSION_PATCH)
SET(OSG_OSX_SDK_NAME "macosx${MACOS_VERSION_MAJOR}.${MACOS_VERSION_MINOR}")
Also i added the check for the new Version to some more find scripts.
Additionally the nil object in Objective C now seems to be equivalent with a null_ptr that cannot be passed as GLInt anymore. So i switched this in the PixelBufferCocoa.mm to pass a zero instead of nil.

My changes:
-------------------
- I changed the cmake files and added a toolchain for building OSG in Android. The toolchain is based on the one used at OpenCV. For building OSG for android you just need to do:
mkdir build_android_static_gles2 && cd build_android_static_gles2
cmake .. -DANDROID_NDK=<path-to-the-android-ndk>
-DCMAKE_TOOLCHAIN_FILE=../PlatformSpecifics/Android/android.toolchain.cmake
-DOPENGL_PROFILE="GLES2"
-DDYNAMIC_OPENTHREADS=OFF
-DDYNAMIC_OPENSCENEGRAPH=OFF
-DANDROID_NATIVE_API_LEVEL=15 # optional
-DANDROID_ABI=armeabim #optional
-DCMAKE_INSTALL_PREFIX=<path-to-the-install-path> #optional
make -j 8
make install
The OPENGL_PROFILE works as expected, changing it to "GLES1" it builds and links OSG using GLES1.
The DYNAMIC_OPENTHREADS/DYNAMIC_OPENSCENEGRAPH parameters also allows to build the dynamic libraries
- I also added some build fixes for android related to the texture formats and added some missing USE_OSG_SERIALIZER_WRAPPER in the osg serializer library to support loading osgb files in static."

The State::AppliedProgramObjectSet wasn't ever being used actively in the current rev of the OSG so populating and clearing was no longer neccessary, allowing the code to be removed completely.

Currently this submission is Windows-only. I don't think OSX or Linux require any help in locating gl/glcorearb.h. But if they do, this submission can be easily modified.

To select standard OpenGL 1/2 build with full backwards and forwards comtability use:
./configure
make
OR
./configure -DOPENGL_PROFILE=GL2
To select OpenGL 3 core profile build using GL3/gl3.h header:
./configure -DOPENGL_PROFILE=GL3
To select OpenGL Arb core profile build using GL/glcorearb.h header:
./configure -DOPENGL_PROFILE=GLCORE
To select OpenGL ES 1.1 profile use:
./configure -DOPENGL_PROFILE=GLES1
To select OpenGL ES 2 profile use:
./configure -DOPENGL_PROFILE=GLES2
Using OPENGL_PROFILE will select all the appropriate features required so no other settings in cmake will need to be adjusted.
The new configuration options are stored in the include/osg/OpenGL header that deprecates the old include/osg/GL header.
Added the Cmake option OSG_USE_LOCAL_LUA_SOURCE to control whether to build and use the Lua source code in the lua plugin, or look for lua as an external dependency.
* fixed a bug with multi-touch and touch-id-generation on iOS and OS X. (will fix a bug reported by Colin Cochran, without ditching the existing logic)
* removed unnecessary warning-flagss when generating xcode-projects via cmake, will enable the usage of OSG_AGGRESSIVE_WARNING_FLAGS
* added support for 10.9 (OS X)
* new cmake-variable: IPHONE_VERSION_MIN, this will set the deployment-target (previously hard-coded) If you set the IPHONE_VERSION_MIN to something like 7.0 osg gets compiled also for 64bit (amd64)
* cmake defaults now to the clang compiler if IPHONE_VERSION_MIN > 4.2
* cmake now sets some xcode-settings so the compiler uses the c++98-standard (clang defaults to c++11, w/o this I got a lot of linking errors)
* removed include-dir for avfoundation-plugin as not needed on OSX/IOS.
* enhanced the ios-example, will now show multitouch-information on a hud (similar to the osgmultitouch-example), and more importantly, will compile + link out of the box
* small enhancements for the osc-device-plugin (send only one msg for MOVE/DRAG, even if multiple msgs/event is enabled)
* better memory-handling for the zeroconf-plugin
* fixed a possible bug in the rest-http-plugin when receiving mouse-events.
* incorporated a fix from Colin Cochran "forwarded touch events are not transformed into the GL UIView“

Provided are lua, python and V8 (for javascript) plugins that just open up enough of a link to the respective libs to run a script, there is no scene graph <-> script communication in current implementation.
New methods osg::Geometry::containsDeprecatedData() and osg::Geometry::fixDeprecatedData() provide a means for converting geometries that still use the array indices and BIND_PER_PRIMITIVE across to complient
versions.
Cleaned up the rest of the OSG where use of array indices and BIND_PER_PRIMITIVE were accessed or used.

It now points to sdk version 6.0 (I do intend to make this configurable my command line)

* avfoundation: added support for IOS (CoreVideo-support is still in development, works only for SDK >= 6.0, set IPHONE_SDKVER in cMake accordingly)
* zeroconf: added ZeroConf-device-plugin (Mac/Win only, linux implementation missing) to advertise and discover services via ZeroConf/Bonjour, on windows you'll need the Bonjour SDK from Apple
* osgosc: modified the example to demonstrate the usage of the ZeroConf-plugin (start the example with the command-line-argument --zeroconf)

Which is fragile because XCode could be installed into another directory than /Developer. (In case XCode is not installed into the /Developer directory CMake can automatically resolve the path via command line utility ${CMAKE_XCODE_SELECT} --print-path)
This issue bites me currently because the latest XCode (Version 4.3.1 - 4E1019) installed through the Mac App Store is per default installed in "/Applications/Xcode.app/Contents/Developer" and hence the 10.7 SDK in "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk"
Searching the web to find the proper way to determine the version of the Platform SDK programmatically, I found no standard way. I came up with 2 options myself:
1) Parse the path string to extract the version number
2) Read a value from the SDKSettings.plist found in the root of each SDK (e.g., "defaults read ${CMAKE_OSX_ROOT}/SDKSettings.plist CanonicalName" gives "macosx10.7")
I implemented the last option and verified that at least the following Mac OS SDKs (10.3.9, 10.4, 10.5, 10.6, 10.7) support this method. It also looks reasonably future proof. An additional benefit of this method is that it also seems to be compatible with iOS and iOS Simulator SDKs (at least for version 5.1, but I assume this also applies to older versions). This is interesting because the CMake infrastructure to build OSG for iOS currently still contains similar hard-coded paths and even requires you to manually change the cmake file to build for another iOS SDK version. In the near future I hope to address these issues, but I haven't been able to try this yet."
I added AFAIK proper defaults for several Macos X Version API targets.
* In order to determine which defaults to apply, consult the CMAKE_OSX_SYSROOT variable pointing to the used SDK, not the pure existence of an SDK.
* Defaults are now:
10.7: Support Intel 32 and 64 Bit Cocoa with imageio picture reader
10.6 + 10.5: Support Cocoa with imageio on Intel and PowerPC
10.4: Carbon, Quicktime and PowerPC
Now OSG compiles out of the box for MacOSX 10.7. , tested with gcc and clang with FlightGear."
(http://gta.nongnu.org). This allows to read and write floating point
image data. Unlike other formats, GTA also allows very good compression
ratios for floating point data. The compression method can be selected
with the COMPRESSION option of the plugin.

2nd - Script to use a 3rd party directory with basic libraries: libjpeg,libpng,libtiff,giflib,freetype,curl,gdal.
3rd - Change in the GLES library loading for Android. That should make GLES2 work properly.
4rth- Included two defines RGB8_OES and RGBA8_OES as a substitute in GLES for RGB8 and RGBA8
5th - OpenGL and GLSL version identification changed to recognize GLES versions properly
"
I also modified the CMake and pkgconfig files to append the _POSTFIX extenstion based on the CMAKE_BUILD_TYPE.
Additionally I fixed packaging/ld.so.conf.d/openscenegraph.conf.in to add a '/' betweeen the arguments since the CMAKE_INSTALL_PREFIX can't end with a '/'.

This feature has been introduced to cmake in 2.8.3, on older versions it should be ignored silently. I tested on Visual Studio 2008 with cmake 2.8.3 and 2.8.4.
See the screenshots for comparison [img]osg_solution.png[/img]
This needs few changes:
activate on global cmakelist.txt:
[code]set_property(GLOBAL PROPERTY USE_FOLDERS On)[/code]
set appropriate folder names for project type in osgMacroUtils.cmake:
[code]SET_TARGET_PROPERTIES(${CORELIB_NAME} PROPERTIES FOLDER "OSG Core")[/code]
similar for examples, applications"
"- In order to build against GLES1 we execute:
$ mkdir build_android_gles1
$ cd build_android_gles1
$ cmake .. -DOSG_BUILD_PLATFORM_ANDROID=ON -DDYNAMIC_OPENTHREADS=OFF

If all is correct you will have and static OSG inside:
build_android_gles1/bin/ndk/local/armeabi.
- GLES2 is not tested/proved, but I think it could be possible build
it with the correct cmake flags.
- The flag -DJ=2 is used to pass to the ndk-build the number of
processors to speed up the building.
- make install is not yet supported."
changes from the DirectInput devices and add events to the event
queue. I've tested with the keyboard and joystick supports. Because of
only having a very old 6-button gamepad, I can't do more experiments.
Hope this will bring more ideas to those who face similar problems,
especially simulation game designers. :)
I didn't map all DirectInput key values to GUIEventAdapter key
symbols. Users may add more in the buildKeyMap() function freely. The
mouse handling operations are also ignored, but will be easily
improved in the same way of creating keyboard and joystick devices.
Please add a line:
FIND_PACKAGE(DirectInput)
in the CMakeLists of root directory. And in the examples/CMakeLists.txt:
IF(DIRECTINPUT_FOUND)
ADD_SUBDIRECTORY(osgdirectinput)
ENDIF(DIRECTINPUT_FOUND)
DirectX SDK 2009 is used here, but an older version like DX8 should
also work in my opinion.

attached you'll find the second part of the IOS-submission. It contains
* GraphicsWindowIOS, which supports external and "retina" displays,
multisample-buffers (for IOS > 4.0) and multi-touch-events
* an ios-specific implementation of the imageio-plugin
* an iphone-viewer example
* cMake support for creating a xcode-project
* an updated ReadMe-file describing the necessary steps to get a
working xcode-project-file from CMake
Please credit Thomas Hogarth and Stephan Huber for these changes.
This brings the ios-support in line with the git-fork on github. It
needs some more testing and some more love, the cmake-process is still a
little complicated.
You'll need a special version of the freetype lib compiled for IOS,
there's one bundled in the OpenFrameworks-distribution, which can be used."
Notes, from Robert Osfield, modified CMakeLists.txt files so that the IOS specific paths are within IF(APPLE) blocks.
But I also found rev. 11354 (from Wang Rui) added a change in OsgMacroUtils which adresses a similar issue: Wang told the "../../bin" prefix wasn't working. However I think the fix isn't correct because it checks the MSVC version instead of the CMake version. Here is my fix, against latest trunk (root CMakeLists.txt, and CMakeModules/OsgMacroUtils.cmake).

CMake 2.6.4 | | OK | N/A
CMake 2.8.0 | | OK | broken support?

changed extensions from .c to .cpp and got compiling as C files as part of the osg core library.
Updated and cleaned up the rest of the OSG to use the new internal GLU.

instead of unconditionally.
2. New .pc file for osgQt, also created only if that library is actually
compiled.
