Hi Riccardo,
I have used the ndk-build command and (after long time J ) it has finished apparently without errors. The I have copied the files to the osgViewer project (under the obj folder). After that, I have tried to compile using ndk-build, and I got this error: Compile++ thumb : osgNativeLib <= osgNativeLib.cpp /bin/sh: -Itype: No such file or directory make: *** [/cygdrive/c/Projects/Eclipse/osgViewer/obj/local/armeabi/objs/osgNativeLib/ osgNativeLib.o] Error 1 Of course, there is no such file in that folder. I neither have been able to find that file in the OSG folder. So, maybe compilation has not worked correctly?

If so, probably there's something wrong with the makefile generated by CMake... Regarding the osg Android example, the folder structure is the same as the one of the NDK examples. 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). HTH, Ricky 2011/8/12 Héctor Martínez <[email protected]> Hi and thank you. I first tried with the Cmake GUI, but I got some errors. After that, I have read your answer pointing to command line. I have used the cmake command line (not without some problems J ): cmake -> OK make -> Error: make[3]: *** [/cygdrive/c/Projects/OpensSceneGraph-3.0.1/OpenSceneGraph/obj/local/armeabi -v7a/objs/osgdb_serializers_osg/BlendEquation..o] Error 126 make[3]: *** Waiting for unfinished jobs . make[2]: *** [Android-OpenSceneGraph] Error 2 make[1]: *** [CMakeFiles/ndk.dir/all] Error 2 make: *** [all] Error 2 After that, I have tried to use make install and it has finished without error, but I think this is a weird behavior. Anyway, does somebody now how to solve the problem? And another question, after compiling (if I can make it J ), what files (and where) will I need to include in the OSG Android example? Thank you.

I have never used CygWin and I am trying to follow those instructions: <http://www.openscenegraph.org/projects/osg/wiki/Support/PlatformSpecifics/C ygwin> http://www.openscenegraph.org/projects/osg/wiki/Support/PlatformSpecifics/Cy gwin Those are for building OSG with cygwin to be used on a PC. But it is a bit messy for me. Mourad, it seems like you have successfully compiled OSG for Android in Windows. Could you please give me a quick guide or some tips? 1/ install Cygwin ^^ , make sure to install gcc , g++, make, ... (a full install may be helpful). Please note that, although we won't be compiling osg with cygwin's g++ , it needs to be installed in order for cmake to get over compiler checks at the beginning of configuration. (and other packages may be also needed) 2/ in cmake gui, set the sources and binairies folders, hit configure and choose "Unix Makefiles" as generator 3/ Check "OSG_BUILD_PLATFORM_ANDROID" and hit configure 4/ Set (if not set) ANDROID_NDK path 5/ Configure your build whether you want GLES1 or GLES2 following these instructions : http://www.openscenegraph.org/projects/osg/wiki/Community/OpenGL-ES 6/ Configure and Generate 7/ open Cygwin batch, cd to binaires dir, and "make" Héctor Cheers, Mourad After re trying and checking, i found out that it is preferable to use the command line cmake in cygwin rather than cmake gui : cmake .. -DOSG_BUILD_PLATFORM_ANDROID=ON -DDYNAMIC_OPENTHREADS=OFF -DDYNAMIC_OPENSCENEGRAPH=OFF -DOSG_GL_DISPLAYLISTS_AVAILABLE=OFF -DOSG_GL_MATRICES_AVAILABLE=ON -DOSG_GL_VERTEX_FUNCS_AVAILABLE=ON -DOSG_GL_VERTEX_ARRAY_FUNCS_AVAILABLE=ON -DOSG_GL_FIXED_FUNCTION_AVAILABLE=ON -DOSG_CPP_EXCEPTIONS_AVAILABLE=OFF -DOSG_GL1_AVAILABLE=OFF -DOSG_GL2_AVAILABLE=OFF -DOSG_GL3_AVAILABLE=OFF -DOSG_GLES1_AVAILABLE=ON -DOSG_GLES2_AVAILABLE=OFF Mourad _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
