The compile instructions state to compile it all in static mode - also the

because usually libraries generate shared or static libraries consitently. This

Hi,
In the meanwhile, I was working further on the topic - and cracked it this
time, I think. First and foremost, I use OpenSceneGraph 3.3.8 (still) and
compile it for Android, while having the necessary 3rdParty-folder inside the
OpenSceneGraph root folder (little suggestion: at some point
Today, I changed the strategy a bit: because the linker fails to reference the
functions, the NDK says there is the option to include the whole static
library, which I did by now (see Android.mk.txt file).
The new error does not find the base functions of the pre-compiled 3rd party
libraries:
As in my second post, I already tried that solution and still end up with the
same problem, so in the case of our plugins, this either doesn't seem to work
or I still have a mistake in the mk-file when building the local modules.
(probably the second :-) )

Hi,
I re-open the earlier question because the momentary questions fits into it: as
Rafa already mentions, until now the osgPlugins for jpeg, png, tiff, curl etc.
are not included in the package. For just rendering a .osg file that includes
such texture references, it is sufficient to put the
to b) from myself:
I read through the android doc, and it suggests to include the libraries as
prebuild, so I added lines like this (see Android.mk.txt for the full file):
OSG_SDK:=/media/christian/DATA/android-osg-sdk/gles1/${APP_ABI}
OSG_SDK_3RDPARTY_LIB_PATH:=${OSG_SDK}/obj/local/${APP_ABI}
A final remark on the question: I now implemented the memory-intensive method
as a static native-JNI method in C++, having a static function call in Java
left. First experiments with formerly crashing data indicate to really use C++
native methods for full-geometry modification processes (e.g.
Hi Rafa,
Thanks for the feedback - I'll have a look into the osgjni part again. The
extended wrappers work well until now, but the arrays (Vec2,3,4Array) I just
wrapped via their object pointer in osgAndroid, as all other classes. So, I can
add them to the upper-level geometry, but somwhere
Hi to everyone,

Hi Jan,
Your last post suggests we are talking about different repositories. What I did
is compile osg 3.3.8 for Android using the cmake command line. Then, I use
Rafa's osgAndroid from github. This package includes 4 projects: osgAndroid,
osgjni, osgSimple and osgcamera. osgAndroid (at least
I went through the build process again and have to correct: osgAndroid already

libjniosg-gles1.so file that links to the static c++ libraries. HENCE, my
question would be now how the pre-compiled

Hi,
I still didn't get it to work. I spoke with an Android developer the recent
days, told him the problem. His suggestion: move the requested library files in
the libs-folder of your project, which is how the Android jni usually works.

Hi Jan,
I join your thinking. The compilation is done using the cmake line from Rafa
(see post Sat May 02, 2015 7:48 am), and because it compiles OSG as static, I
somehow doubt the compilation is wrong. That said, you may be right that the
library is registered incorrectly. Thing is: I have

Thanks Rafa, I'm giving it a try! Could you also quickly tell me which osg

So, I needed to uncomment my submitted fix in GLDefines again, but with that, I

So, what I tried now is to revert to the old OpenSceneGraph. I was looking up

Hi,
I had a closer look to the errors and the Android.mk file.
osgdb_serializers_osgpresentation doesn't exist in my build (perhaps missing in

that is added and missing in the build).

I posted the changes on the osg-submissions mailing list. I still have the

give me a hint on how to do that, or extend the readme on the project a bit
further so this last step is clear on howto-do ?

Check whether you have any .so files generated for OSG. You shouldn't have
