setVertexAttribArrayList(array) with array containing NULL vertexAttrib.
I added a test in order to avoid it
Code:
void Geometry::setVertexAttribArrayList(const ArrayList& arrayList)
{
_vertexAttribList = arrayList;
dirtyDisplayList();
if (_useVertexBufferObjects)
{
for(ArrayList::iterator itr = _vertexAttribList.begin();
itr != _vertexAttribList.end();
++itr)
{
if(itr->get())//ADDED
addVertexBufferObjectIfRequired(itr->get());
}
}
}
"
and
"The bug i ran into is a crash reading osgt Geometry with null vertexattribs.
The only thing i added is a not nul check on array passed to setVertexAttribArrayList."

I used osgSetGLExtensionsFuncPtr to remove the symbols. I don't know how to test this path, but it did remove the symbols from libosgViewer.so. I have also not been able yet to see if that was sufficient for our customer.
I did this by looking at other cases, and I tried to follow some of the same practices in PixelBufferX11, like using _useSGIX in a similar way to the previous _useGLX1_3."

but was not able to use them for a while. Attached are changes to
OsgAndroidMacroUtils.cmake that allow the deps to be found by cmake.
Specifically, all FIND_PATH commands require the
NO_CMAKE_FIND_ROOT_PATH option to actually find paths. This is odd
because if you inspect CMAKE_FIND_ROOT_PATH it appears to be empty. I
would expect it to have no effect at all.
I also needed to remove quotes from this line in order for headers to be found:
set(FREETYPE_INCLUDE_DIRS "${FREETYPE_DIR}/include
${FREETYPE_DIR}/include/freetype/config")
Assuming this script worked in the past, it seems like cmake behavior
may have changed at some point. I'm using cmake version 2.8.12.2."

On a Intel HD graphics Linux system with Mesa 10.1.3, I found that osg's Extensions::isTextureCompressionS3TCSupported() returned false, even though S3TC compressed textures *are* in fact working. I tested this by loading and rendering various DXT1, DXT3 and DXT5 compressed textures in the OSG.
"glxinfo | grep s3tc" gives:
GL_S3_s3tc
Note, if I install the package "libtxc-dxtn-s2tc0", I get in addition:
glxinfo | grep s3tc
GL_EXT_texture_compression_s3tc
GL_S3_s3tc
However, S3TC compressed textures worked correctly within the OSG even without libtxc-dxtn-s2tc0 installed.
I'm not sure what the differences between these extensions are, but based on the description at https://www.opengl.org/registry/specs/S3/s3tc.txt I would assume that both will work for OSG's purposes. The attached patch changes isTextureCompressionS3TCSupported() to accept either extension."

This gives arise to the requirement that a static initialization of a QObject cannot occur for the Android platform, as Qt incorrectly considers that first thread the “main” one before a client application has even begun executing in its second thread.
The HeartBeat in GraphicsWindowQt.cpp is a QObject static global initialized at load time, causing the above issue. This changeset changes it to be a singleton that is constructed upon first access to its “instance” method.
I have:
- added the static method “instance”,
- moved its constructor to be private, and
- changed the one place it is accessed to access it through the “instance” method.

Changes by Robert are to adopt QPointer<HeartBeat> rather than use a C pointer to ensure that the HeartBeat object will be cleaned up automatically rather than leaked.
