Re: [osg-users] osg3.0.0+qt5.2.1 got error:C2371: “GLintptr”: redefinition?
Hi
don't think it will work with the Angle based build of Qt, you need to get the
OpenGL precompiled one, or build from source with the -opengl desktop config
option

Re: [osg-users] Building OSG 3.2 With GDAL Support
Hi you should be able to specify it explicitly like this: cmake -DGDAL_INCLUDE_DIR:PATH=\/path/to/gdal/include\ -DGDAL_LIBRARY:PATH=\/path/to/gdal/lib/libgdal.a\ …. So be able to specify .so if you're using the dynamic library This is how I do it when cross compiling for iOS.

Re: [osg-users] iOS OSG
Hi
right got complete build, Xcode 4.6, SDK 6.1, OSG 3.2 branch (built with
OpenGLES 2.0 only). All links and runs, it loads .osgt files, but I get errors
at runtime when shaders get compiled (see below). I'm not adding the shaders,
it seems to be the default ones OSG adds. The code is basically the same as
osgviewerIPhone…
any ideas as to why it may not work?

[osg-users] osgQt (3.2), osgearth and Qt 5
Hi getting a crash on startup with osgQt (from osg 3.2.0), osgearth (from trunck) and Qt 5.1.0 Basically: - osgearth queries capabilities by calling osg::GraphicsContext::createGraphicsContext() - this creates a GraphicsWindowQt - this in turns creates a GLWidget, setting GraphicsWindowQt::_ownsWidget to true - once osgearth is done with the GraphicsWindow, this goes out of scope and is deleted - in it's destructor, GraphicsWindow removes itself from the GLWidget, BUT DOES NOT DELETE IT - later at some point Qt5 sends resize events to the widget (because GraphicsWindowQt) - and GLWidget::resizeEvent() does not check it the _gw and hence crashes… So it seems to be me GraphicsWindowQt:: ~GraphicsWindowQt() should delete the widget if GraphicsWindowQt created the widget in the first place… Has anyone come across this behaviour?

[osg-users] OSG + QT + Mac focus issue
Hi I have a bug where, after closing an OSG widget, keyboard events don't get sent properly. We use Qt4.8.4 and OpenSceneGraph (latest version from SVN). We create several qwidgets as tabs widgets, and have the ability to close them (using a kb short cut or the close button on the tab). The OSG widget uses osgQt. When the OSG widget is closed, I no longer get keyboard event anywhere in the app even though focus appears to be properly set. Using the debugger, I see the event is received in QT's code in - (void)sendEvent:(NSEvent *)event in qcocoasharedwindowmethods_mac_p.h which then calls [super sendEvent:event]; but this fails somewhere in Apple's toolkit code and the application beeps (not by calling Qt's beep function). It would normally end up calling - (void)keyDown:(NSEvent *)theEvent in qcocoaview_mac.mm I tracked down the closing of the OSG widget to see if it was doing anything weird, but it all seems fine. I don't know if the bug is with our code, Qt or OSG but I'm failing to find out why this is happening and was wondering if anyone had come across anything like that.

those worked fine. not sure what I was doing when but the builds I tried to do did not work (crashed within Qt).

[osg-users] OSG + Mesa3D
Hi we've been having issues with running our application with OSG via Remote Desktop on Windows, resulting in crashes in Microsoft Software OpenGL driver when encountering large meshes (as in more than a couple thousand triangles). Messages on this list suggest using Mesa3D. Compiling from source on Windows seems non trivial, and I was wondering if someone had precompiled version of Mesa3D they would be willing to share? Need Windows 32 and 64 bits versions, built with MS VS 2010 SP1.

Re: [osg-users] OSG + Mesa3D
Hi consensus seems to be that RDP is not an option for modern 3D graphics anyway. There's a few alternatives around though, so I don't think we'll be implementing anything specific on our side. Just a matter of providing recommended solutions for our customers Thanks, Mike On 27 Nov 2012, at 11:16, Robert Osfield wrote: A more general suggestion I have is that perhaps rendering the image on the remote system and then returning this image to the client would be the more robust way to handle this type of usage rather than relying upon remote desktop. This approach would require more work at the application level but would avoid passing large amounts of vertex and texture data across the network and not be limited to specific versions of software drives - the MS OpenGL driver supports very few modern OpenGL features so is best avoided.

W.r.t finding fonts, or any files, trying using set the env OSG_NOTIFY_LEVEL to DEBUG and then look for entries relating to FindFileInPath, these should tell you where the OSG is looking for the fonts. Another avenue you could look at is to try the fonts provided in the OpenSceneGraph-Data distribution, as perhaps the fonts you are attempting to read can't be loaded by freetype. Robert.

Re: [osg-users] issue with OSG on Mac OS Lion
Hi thanks for the details. We recently tried to the visibility flag thing on GCC to try and speed up link times. What not significantly improving it anyway so happy to do without it.

Any explanation why? is it an llvm-gcc bug? no, it's not a bug, it's a feature :) Basically gcc's dynamic_cast compares two classes by pointer to their type_info and not by their names, so if you have the same class compiled in your app and in your lib, the dynamic_cast will fail, if visibility is set to hidden, as the linker cannot merge the two classes into one.

Hi On 20 Sep 2012, at 19:57, Stephan Huber wrote: I've seen this when mixing clang and gcc-compiled code (lib compiled with clang, app compiled with gcc, or vice versa). One symptom was a dynamic_cast returning NULL instead of the correct instance. Double-check the settings for the compilerof your app and of osg. we don't build with clang because some of other 3rd part dependencies include really old template code that clang doesn't like. We build everything with llvm-gcc that comes with Xcode (not plain gcc). I initially tried plain GCC 4.7 but OSG does not build with that because of the Objective-C code inside (at least not on the 10.6 and up SDKs). Did you change the visibility-flags? yes, our app does have the visibility flags enabled, OSG build does not I believe… Will try turning those off. What version of Xcode do you use? Try the latest, Xcode 4.5. We use 4.4.1, will upgrade now, been needing to do it for iOS 6 support anyway… Cheers!

[osg-users] issue with OSG on Mac OS Lion
Hi I'm having issues with OSG (from head in Subversion) when built on Mac OS 10.7. The actual build is fine but I'm having strange run time issues. For example, when doing a picking, osgUtil::LineSegmentIntersector::Intersection::indexList is always empty. Or the smooth normal visitor does not generator normals. In both case I tracked it down to this dynamic cast failing: osg::Vec3Array *coords = dynamic_castosg::Vec3Array*(geom.getVertexArray()); The resulting coords is null despite the actual member variable being of the right type. This (to me) sounds like a weird build issue, but I don't have a clue what's causing it. Here's how I build OSG: cmake -DCMAKE_C_COMPILER:STRING=/usr/bin/llvm-gcc -DCMAKE_CXX_COMPILER:STRING=/usr/bin/llvm-g++ -DCMAKE_SHARED_LINKER_FLAGS:STRING=-headerpad_max_install_names -DCMAKE_OSX_ARCHITECTURES=x86_64 -DOSG_GL3_AVAILABLE:BOOL=OFF -DADDITIONAL_MAKE_CLEAN_FILES=bin -DADDITIONAL_MAKE_CLEAN_FILES=lib -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/some/path .. I had tried using -DOSG_USE_REF_PTR_IMPLICIT_OUTPUT_CONVERSION:BOOL=OFF but it did change a thing All other third party dependencies (GDAL and ZLib) are built the same way, all with the 10.7 SDK using the llvm compiler (/usr/bin/llvm-gcc - ../llvm-gcc-4.2/bin/llvm-gcc-4.2). The other dependencies are the platform defaults. Any ideas?

Re: [osg-users] Problems with DotOsgWrapper in OSG 3.1.1 on OSX 10.7
Hi, I had a everything working using GCC 4.2.1 from XCode 4.3 but due to issues with GDAL I've had to upgrade to GCC 4.3 from MacPort. So I have: /opt/local/bin/gcc - /opt/local/bin/gcc-mp-4.3 which is found by default with CMake. I'm getting issues when building the Cocoa code: Code: [ 21%] Building CXX object src/osgViewer/CMakeFiles/osgViewer.dir/GraphicsWindowCocoa.mm.o In file included from /System/Library/Frameworks/Foundation.framework/Headers/NSArray.h:5, from /System/Library/Frameworks/Foundation.framework/Headers/Foundation.h:10, from /System/Library/Frameworks/Cocoa.framework/Headers/Cocoa.h:12, from /Volumes/MVEData/Users/Mike/Developer/OSG/src/osgViewer/GraphicsWindowCocoa.mm:18: /System/Library/Frameworks/Foundation.framework/Headers/NSObject.h:140: error: stray '@' in program Any ideas on how to fix this? Or anybody know if I can safely build the rest with GCC 4.3 and OSG with the llvm-gcc 4.2 that comes with XCode? Thank you!
