Hi Jordi,
thanks for getting back to me. I did compile with OSG in static mode. Here are
the flags I'm using:
OSG_GLES2_VARS="-DOSG_GL1_AVAILABLE=OFF \
-DOSG_GL2_AVAILABLE=OFF \
-DOSG_GL3_AVAILABLE=OFF \
-DOSG_GLES1_AVAILABLE=OFF \
-DOSG_GLES2_AVAILABLE=ON \
-DOSG_GL_LIBRARY_STATIC=OFF \
-DOSG_GL_DISPLAYLISTS_AVAILABLE=OFF \
-DOSG_GL_MATRICES_AVAILABLE=OFF \
-DOSG_GL_VERTEX_FUNCS_AVAILABLE=OFF \
-DOSG_GL_VERTEX_ARRAY_FUNCS_AVAILABLE=OFF \
-DOSG_GL_FIXED_FUNCTION_AVAILABLE=OFF"
OSG_ANDROID_VARS="-DDYNAMIC_OPENTHREADS=OFF \
-DDYNAMIC_OPENSCENEGRAPH=OFF \
-DOSG_BUILD_PLATFORM_ANDROID=ON \
-DANDROID_ABI=\"armeabi armeabi-v7a\" \
-DANDROID_PLATFORM=7 \
-DANDROID_STL="gnustl_static" \
-DANDROID_DEBUG=OFF \
-DANDROID_NDK=${ANDROID_NDK_ROOT} \
-DJ=12"
cmake ${OSG_ANDROID_VARS} ${OSG_GLES2_VARS} -DCMAKE_BUILD_TYPE=Release
-DCMAKE_INSTALL_PREFIX="${GLOBAL_OUTDIR}/osg-${VERSION}/${TOOLCHAIN}"
I wondered about that too, because OSG is searching for a dynamic library in
osgPlugins-3.2.1/ directories. I thought I didn't need to add this directory
with the plugins on to my device. As far as I can see I don't have an
osgPlugings directory produced by my OSG build for Android in the same way I
would for PC. Is this something I need to do? If so I would appreciate a link
to any instructions available.
Thanks,
Nathan

Hi Nathan,
Did you compile OSG in static mode as stated in the documentation?
-DDYNAMIC_OPENTHREADS=OFF
-DDYNAMIC_OPENSCENEGRAPH=OFF
Right now is a must to compile in static mode. We have some tests with dynamic
libraries but compiling in dynamic mode involves too many changes and we have
still work to do to make it public.
Hope it helps.

Hi,
I have compiled OSG for Android, and built and deployed the GLES2 Android
example on my Nexus 4. However I’m having trouble loading cow.osg, or any other
.osg/.osgt files, to test that it works. I’ve built OSG for Android in the past
and had these models working but this time around I’m not able to load any
models at all. I get the following warnings from logcat:
01-09 16:46:11.812: E/Osg Viewer(18327): There are 1 models to load

01-09 16:46:11.812: E/Osg Viewer(18327): Model not loaded
Now I thought I didn’t have to do anything special last time to load an .osg
file but I’m wondering what I’ve missed? My Android.mk file just has the
standard set OSG_ANDROID_DIR and add path/to/libgnustl_static.a in LOCAL_LDLIBS
modifications. I’m working with OSG branch 3.2 on Fedora, with ndk-r9c.
Any help would be greatly appreciated. Thanks,
Nathan
