Re: [osg-users] OSG for Android
Mmm first it doesn't find the plugins because you don't have them xD we have a third party package that... it seems we forgot to publish the link in the wiki (and i don't know the address in my head). The other thing is probably a error because i think ndk is not prepared to run in windows as it is. I think you need mingw or something like that. I use to make my tests over Linux so I don't know exactly the conditions that google have for windows.

Re: [osg-users] OSG for Android
There's no trouble in that. Android binaries are platform independant (they are from Android) and I suppose following the google instructions shouldn't give much trouble to anyone.

Re: [osg-users] OSG for Android
Hi guys, it works!! I had to tweak something and then I've run some tests, let me share some points with you: - Builing I have made a floder called ndk-build inside the osg folder tree to place all the nkd builind stuff. If I set the OSG_ANDROID_DIR to that folder, the compiler doesn't file the osg includes, so I had to add the osg include folder to the "LOCAL_C_INCLUDES". By doing that everything compile and link. What I don't get is why it wasn't working before, when I had edited directly the variables LOCAL_C_INCLUDES and LIBDIR by setting them to full paths -> any hints on this point?? - Running I've been trying only the GLES1 example, and it works just fine on my Nexus S (android 2.3.4) Instead I've tried to build the example also for the 3.x platform target: it build and upload on my tablet, but it just shows up for a couple of seconds and then it dies. I have no time to investigate right now, I'll run some more tests tomorrow. Have you got any idea what it might be depending on? My device is an Acer Iconia Tab A500. Thank you for your support and great job!

Re: [osg-users] OSG for Android
I don't have very much idea what can happen with 3.X it would be needed to see in detail the Logcat to find what's happening. 2.3 and 3.X have the same base in common so it shouldn't be anything big. About the other things probably is just that you didn't do a make install to create a directory with all the includes etc. 2011/8/11 Riccardo Corsi > dk-build inside the osg folder tree to place all the nkd builind stuff.

Re: [osg-users] OSG for Android
Hi Hector, maybe you can try to use the ndk-build command instead of "make", and see if it runs smooth. 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).

Re: [osg-users] OSG for Android
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?

Re: [osg-users] OSG for Android
I usually install it in a separate directory because there's no point in installing it into system. It would be trouble with the standard linux installation on your system. I usually build it out of the OSG svn directory, i don't like mix svn and not svn things. And, of course last time I tested everything (about two weeks) all was running in thrunk. About linking, one again that's just an error of not finding the librarie. In that case is the dds plugin. It should not be any trouble if you set the path on the Android.mk (osgAndroidExampleGLES*/jni) Line:7 OSG_ANDROID_DIR := "type your install directory here" Which SETS both LOCAL_L_INCLUDES and LOCAL_LDFLAGS variables according to the the Target Architecture. And no, there are no other ways supplied. There are other ways to compile with NDK but require scripting and bypassing the usual ndk build. 2011/8/17 Luca Vezzadini > > Jorge Izquierdo Ciges wrote: > > ...

Re: [osg-users] OSG for Android
Hi Jorge, So, that means that I am doing thing in the correct order. After some more test I found out the problem: it's something in Cygwin. If I use relative paths instead of absolute ones everything works fine. No idea why and I don't want to investigate further, but at least now I know it's a cygwin-specific thing... Thanks!

[osg-users] OSG for Android on Mac
Hi, I am trying to build OSG for Android on Mac 10.6.7. I already get Eclipse, Android Plugin and CDT Plugin and also Android NDK. I configure the project with CMake and generate an Eclipse CDT4 project. After that, I create a new Android Project with "Create project from existing source" and add the generated Eclipse CDT4 project. Now, when I try to build this project, I get following error: > Conversion to Dalvik format failed with error 1 > Dx no classfiles specified Are my steps to compile OSG for Android false?

Re: [osg-users] OSG for Android on Mac
Hi Busra, I'm not familiar with Mac dev environment, but I guess that you're trying to build osg with Eclipse CDT with the regular gcc compiler, which is targetting pc architecture. Instead you need to create a makefile suited for the ndk-build. The CMake options you need are fully detailed in the wiki page and in other threads of this mailing list.
