Re: [osg-users] How to build OpenSceneGraph for Android in Windows
Hi Shayne and Allistair, Maybe the OSG documentation about android is not enough (specially if you try to build it in windows). But if you have new tutorials or you can improve the existing ones, don't hesitate to ask for an account to edit http://openscenegraph.com website. New documentation or tutorials are really welcome. To maintain the documentation up to date (this includes to add new docs to compile something) is a work for the whole community. So I encourage you to get involved and collaborate :).

Re: [osg-users] How to build OpenSceneGraph for Android in Windows
You do not need Cygwin installed or active to build NDK code for Android any more - it was a prerequisite for old NDKs, and it is still needed if you want to use Google's Eclipse plug in for C/C++ code debugging, though. From our internal documentation page where Nathan assembled the instructions (he's on holiday right now), the extra bit that you need is probably this: Install Android NDK Available here: http://developer.android.com/tools/sdk/ndk/index.html Extract it to a location with no spaces in the path, such as C:\Local\android-ndk-[ver] Add to your system environment variables: ANDROID_HOME[Android-NDK-Install-Dir] ANDROID_NDK_ROOT[Android-NDK-Install-Dir] Add to your existing PATH: [Android-SDK-Install-Dir]\tools;[Android-SDK-Install-Dir]\platform-tools;[Android-NDK-Install-Dir].

I have managed to build code using just GNU Make and the ndk_build without Cygwin too, but it is unsupported and you are likely to encounter all kinds of bugs - most of the scripts in NDK assume Unix/Linux system and bash being available. I have spent almost a week fighting with a problem that ended up being caused by the version of bash from MinGW (or Git, not sure now) that is patched to actually mangle the path names, pre-pending its own installation directory. That was of course causing ndk_build and other scripts to fail in random ways. That's why Google is asking for Cygwin - it is a known-good quantity.

Obviously there are some steps missing, hence the reason for this discussion. It appears that I would be best served by following your recommendation of following the steps provided on the wiki.

Thanks. I will do that. I'll most likely have more questions as I move along... -Shayne -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Jan Ciger Sent: Tuesday, April 02, 2013 1:25 PM To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] How to build OpenSceneGraph for Android in Windows On 04/02/2013 06:56 PM, Shayne Tueller wrote: Hi Jan, So are you saying that Cygwin is the best way to compile OSG for Android on Windows?

Re: [osg-users] How to build OpenSceneGraph for Android in Windows
Revision 13218 introduced a Bug that breaks Android execution (not compilation), Still, OSG 3.1.3 works. 2013/2/13 Jordi Torres jtorresfa...@gmail.com Hi Nathan, Could you say if you can compile the trunk version after a svn update?

Re: [osg-users] How to build OpenSceneGraph for Android in Windows
Hi Nathan, good tutorial! It could be useful to post this to the android section of the new openscenegraph joomla site: http://www.openscenegraph.com/index.php/documentation/platform-specifics/android Cheers. 2013/2/4 Nathan Collins nat...@mve.com Hi there, We have been attempting to build OSG for Android and thought it would be a good idea to share the steps we used to finally get it to work in Windows. This guide assumes you have Eclipse, the Android SDK and NDK installed and set up already. Whilst you may be used to using the NDK tools in Cygwin, we have only used CMD in this guide. The most important thing is to use the latest stable version of OSG (3.0.1) - we found that the svn trunk version just does not want to work. This is due to issues loading libraries as well as some problems with OSG its self. As usual, your mileage may vary! Install make and MinGW == - Download and install make from http://gnuwin32.sourceforge.net/downlinks/make.php; - Download and install MinGW from http://sourceforge.net/projects/mingw/files/latest/download?source=files. Don't forget to add the C++ compiler during the installation options; - Add the install directories to your PATH. Mine were C:\Program Files (x86)\GnuWin32\bin and C:\MinGW\bin. Setup a clean version of the OSG source === I used a clean version of the OSG source, because we are using a separate set of CMake commands. *** It is important to use the latest stable version (3.0.1), rather than the trunk, otherwise it will not work! *** To get a clean version: - Install tortoise SVN http://tortoisesvn.net/downloads.html ; - In C:\Local use SVN Checkout (a context menu option) http://www.openscenegraph.org/svn/osg/OpenSceneGraph/tags/OpenSceneGraph-3.0.1 Set the checkout-directory to be C:\Local\OpenSceneGraph-Android; - Make two new directories inside OpenSceneGraph-Android: build and osginstall; Now we build the OSG source. NOTE: if you have an NDK_PROJECT_PATH environment variable set you need to remove this now. - In CMD navigate to C:\Local\OpenSceneGraph-Android\build and run the following CMake command (-DJ=8 command tells make to use 8 cores - change this to match your system): cmake .. -G MinGW Makefiles -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 -DJ=8 -DCMAKE_INSTALL_PREFIX=C:\Local\OpenSceneGraph-Android\osginstall - Run make - this takes a while! - Run make install which copies our include, lib and obj files into osginstall for us. Import osgAndroidExampleGLES1 to Eclipse and configure == - Copy a version of the osgAndroidExampleGLES1 from C:\Local\OpenSceneGraph-Android\examples\osgAndroidExampleGLES1 to your workspace: workspace\osgAndroidExampleGLES1; - In Eclipse, File | Import..., expand Android and select Existing Android Code Into Workspace. Next; - In Root Directory browse to workspace\osgAndroidExampleGLES1; - Select the projects osg.AndroidExample.osgViewer and hit Finish; - In Eclipse, open up jni\Android.mk and set OSG_ANDROID_DIR to C:\Local\OpenSceneGraph-3.0.1\osginstall on line 7; - You also need to add -lgnustl_static onto the end of line 21 (LOCAL_LDLIBS); If you have an ndk version greater than android-ndk-r8b: - Open C:\Local\OpenSceneGraph-Android\build\AndroidManifest.xml in a text editor; - Add uses-sdk android:targetSdkVersion=8 android:minSdkVersion=8/uses-sdk as a child of 'manifest'. You should be able to paste it straight into the empty line 6. Finally: - navigate to workspace\osgAndroidExampleGLES1 in CMD and run ndk-build; - plug in a device, or launch an emulator, and debug or run the app in Eclipse. We hope this helps!
