Hello, I'm having a problem building for Android. I can build OSG, but when I try to build the GLES1 example I have these linker errors:
/home/eduardo/src/osg/osg-android/obj/local/armeabi-v7a/libosgdb_osg.a(ReaderWri terOSG.o): In function `OSGReaderWriter::setPrecision(osgDB::Output&, osgDB::Opt ions const*) const': /home/eduardo/src/osg/OpenSceneGraph/src/osgPlugins/osg/ReaderWriterOSG.cpp:295: undefined reference to `std::basic_istringstream<char, std::char_traits<char>, std::allocator<char> >::basic_istringstream(std::basic_string<char, std::char_tr aits<char>, std::allocator<char> > const&, std::_Ios_Openmode)' /home/eduardo/src/osg/OpenSceneGraph/src/osgPlugins/osg/ReaderWriterOSG.cpp:313: undefined reference to `std::basic_istringstream<char, std::char_traits<char>, std::allocator<char> >::~basic_istringstream()' /home/eduardo/src/osg/OpenSceneGraph/src/osgPlugins/osg/ReaderWriterOSG.cpp:313: undefined reference to `std::basic_istringstream<char, std::char_traits<char>, std::allocator<char> >::~basic_istringstream()' There are several other errors related to basic_istringstream, basic_stringbuf, type_info and others. It seems like there is a STL incompatibility. I checked, but both osg and the example seem to be being built with the correct STL include path. The linker command is: /usr/local/android-ndk-r8b/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x 86/bin/arm-linux-androideabi-g++ -Wl,-soname,libosgNativeLib.so -shared --sysroo t=/usr/local/android-ndk-r8b/platforms/android-5/arch-arm ./obj/local/armeabi-v7 a/objs/osgNativeLib/osgNativeLib.o ./obj/local/armeabi-v7a/objs/osgNativeLib/Osg MainApp.o ./obj/local/armeabi-v7a/objs/osgNativeLib/OsgAndroidNotifyHandler.o ./ obj/local/armeabi-v7a/libgnustl_static.a -Wl,--fix-cortex-a8 -L /home/eduardo/s rc/osg/osg-android/obj/local/armeabi-v7a -losgdb_tga -losgdb_osg -losgdb_depreca ted_osgviewer -losgdb_deprecated_osgvolume -losgdb_deprecated_osgtext -losgdb_de precated_osgterrain -losgdb_deprecated_osgsim -losgdb_deprecated_osgshadow -losg db_deprecated_osgparticle -losgdb_deprecated_osgfx -losgdb_deprecated_osganimati on -losgdb_deprecated_osg -losgdb_serializers_osgvolume -losgdb_serializers_osgt ext -losgdb_serializers_osgterrain -losgdb_serializers_osgsim -losgdb_serializer s_osgshadow -losgdb_serializers_osgparticle -losgdb_serializers_osgmanipulator - losgdb_serializers_osgfx -losgdb_serializers_osganimation -losgdb_serializers_os g -losgViewer -losgVolume -losgText -losgSim -losgManipulator -losgGA -losgFX -l osgDB -losgUtil -losg -lOpenThreads -Wl,--no-undefined -Wl,-z,noexecstack -Wl,-z ,relro -Wl,-z,now -L/usr/local/android-ndk-r8b/platforms/android-5/arch-arm/usr/ lib -llog -lGLESv1_CM -ldl -lz -lc -lm -o obj/local/armeabi-v7a/libosgNativeLib. so I have the latest OSG SVN version and the latest SDK and NDK. I'm following the instructions in both http://www.openscenegraph.org/projects/osg/wiki/Support/PlatformSpecifics/Android and http://www.openscenegraph.com/index.php/documentation/platform-specifics/android/43-building-openscenegraph-for-android-3-0-2. I had to change a few "false" to "NULL" in osgNativeLib.cpp to stop gcc from complaining. _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
