HI all, just for the sake of documenting for future readers. I had a look at Ogre3D some config files (which builds and runs ok btw) and I found this CMake option -DANDROID_ABI=xxx. Jan, is this the way how to set the abi. I have built the ogre3d sample with the "armeabi-v6 with VFP" and it runs well in the emulator and the device
Also, by googling about disabling neon I found it was discussed by Jorge and other folks here http://forum.openscenegraph.org/viewtopic.php?t=8959&start=15 You can clarify Thanks again Cheers, Nick On Thu, Apr 11, 2013 at 10:28 AM, Trajce Nikolov NICK < trajce.nikolov.n...@gmail.com> wrote: > Hi Jan, Jorge, > > first of all, thanks for the support in timely fashion !
