[osg-users] OSG on Android with NDK 12 and clang++
Hello, as Android NDK dropped the support of the GNU++ compiler with version 11/12 in favour of clang++ I looked into building OSG for Android with NDK 12. But the build script states that it only supports NDK till version 10c. Will there be support of NDK version 12 any time soon? Or does it matter at all? Also do you know a good tutorial on how to build OSG using clang++ and the "-stdlib=libc++”? Thanks Thorsten___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] OSG for android cube texture problem
Hello everyone：I got a cube texture problem in my program base on ES2.0. The
texture is black, does anyone know what is the problem.Here is my shader code:
*Vertex shader *
varying vec3 Normal;
varying vec3 EyeDir;
uniform samplerCube cubeMap;
void main()
{
gl_Position = gl_ModelViewProjectionMatrix*gl_Vertex;
Normal = gl_NormalMatrix * gl_Normal;
EyeDir = vec3(gl_ModelViewMatrix * gl_Vertex);
}
*Fragment shader *
varying vec3 Normal;
varying vec3 EyeDir;
uniform samplerCube cubeMap;
void main(void)
{
vec3 reflectedDirection = normalize(reflect(EyeDir, normalize(Normal)));
reflectedDirection.y = -reflectedDirection.y;
vec4 fragColor = textureCube(cubeMap, reflectedDirection);
gl_FragColor = fragColor;
}

[osg-users] OSG and Android
Hi, all, I had a question about compiling OSG on Android. I understand that the current advice is to build static libraries instead of shared. I was just wondering why this was the case. Is there some reason that the OSG can't be built with shared libraries instead? The main reason I'm asking is that I'd prefer to avoid having to specify the plugins in the code, and use the normal dynamic loading mechanism, if possible. --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] OSG and Android
Because the shared linker at execution time in Android works as hell on a bench. It just doesn't call the dependencies of a library... and also your shared libraries are not installed on the system... etc The system is just not friendly to use shared libraries. Can OSG be used as a shared library... if you modify it yourself yes. There are some crashes here and there but it's functional. But then you'll have to face all the other worryes of installing the shared libraries... where... for each application and create an ordered library opener. OpenCV had to create another program just to deploy it's own shared libraries. P.S. Oh and I was forgetting that the shared linker on Android when a library has failed to load then it won't try load that library even if you want to force him until he's forgotten the library (mainly when you kill your process) GoodLuck 2013/1/10 Jason Daly jd...@ist.ucf.edu I had a question about compiling OSG on Android.

Hi Jorge, So, that means that I am doing thing in the correct order. After some more test I found out the problem: it's something in Cygwin.

Re: [osg-users] OSG for Android
I usually install it in a separate directory because there's no point in installing it into system. It would be trouble with the standard linux installation on your system. I usually build it out of the OSG svn directory, i don't like mix svn and not svn things. And, of course last time I tested everything (about two weeks) all was running in thrunk. About linking, one again that's just an error of not finding the librarie. In that case is the dds plugin. It should not be any trouble if you set the path on the Android.mk (osgAndroidExampleGLES*/jni) Line:7 OSG_ANDROID_DIR := type your install directory here Which SETS both LOCAL_L_INCLUDES and LOCAL_LDFLAGS variables according to the the Target Architecture. And no, there are no other ways supplied. There are other ways to compile with NDK but require scripting and bypassing the usual ndk build. 2011/8/17 Luca Vezzadini luca.vezzad...@gmail.com Jorge Izquierdo Ciges wrote: ...

Build instructions for native projects are very clear on the ndk online documentation, especially if you use Eclipse. You basically need to build the native part of the example before (under the jni folder) the same way you compiled the native osg libs, and afterwards build the java files under src. They make use of the native lib, and both the java code and the native library will be packed in the apk by Eclipse (or the compiler you're using).

Re: [osg-users] OSG for Android on Mac
Hi Busra, I'm not familiar with Mac dev environment, but I guess that you're trying to build osg with Eclipse CDT with the regular gcc compiler, which is targetting pc architecture. Instead you need to create a makefile suited for the ndk-build. The CMake options you need are fully detailed in the wiki page and in other threads of this mailing list.

Re: [osg-users] OSG for Android
Hi guys, it works!! I had to tweak something and then I've run some tests, let me share some points with you: - Builing I have made a floder called ndk-build inside the osg folder tree to place all the nkd builind stuff. If I set the OSG_ANDROID_DIR to that folder, the compiler doesn't file the osg includes, so I had to add the osg include folder to the LOCAL_C_INCLUDES. By doing that everything compile and link. What I don't get is why it wasn't working before, when I had edited directly the variables LOCAL_C_INCLUDES and LIBDIR by setting them to full paths - any hints on this point?? - Running I've been trying only the GLES1 example, and it works just fine on my Nexus S (android 2.3.4) Instead I've tried to build the example also for the 3.x platform target: it build and upload on my tablet, but it just shows up for a couple of seconds and then it dies. I have no time to investigate right now, I'll run some more tests tomorrow. Have you got any idea what it might be depending on? My device is an Acer Iconia Tab A500.

I don't have very much idea what can happen with 3.X it would be needed to see in detail the Logcat to find what's happening. 2.3 and 3.X have the same base in common so it shouldn't be anything big.

Re: [osg-users] [osg-submissions] Android Development Plans
Hi all,
I gave osg android port a try on Windows using cygwin, and it worked like a
charm (only a tiny problem with osgViewer, when cross compiling for android
using cygwin, the windows path in osgViewer/CMakeLists.txt is used rather
than the android one, fix attached).
For the moment I only compiled all the osg libs and plugins that don't rely
on a 3rdParty lib. I will let you know when I succeed to build an app for my
nexus S :) (the test apk Jorge sent, works for me)
Thanks for your efforts.
Mourad

Attached you will find all required code and cmake modifications (They
are based on a previous submissions I sent last week).
Many thanks for your efforts. I have now merged and checked in
changes to OpenSceneGraph svn/trunk. I haven't tested the Android
build at all yet, only the normal Linux build side.
Would it be possible for you to put up a documentation page on the
wiki to show how to set up to build the OSG on Android?
Thanks,
Robert.

Hi Robert, Thank you very much for reviewing!, We will include some documentation on the wiki, but I have some work trips this weeks so probably Jorge will do the most part.
