Hello, I am just getting my hands on PowerVR with OGLES1.1 on android.  
I have been trying to follow along the training course.  
When I get to the part about using PVRShell, I get some erros when I am trying to make the libraries with ndk-build.  
this is the error:  
  
SharedLibrary&nbsp; : libPVRShell.so  
D:/PowerVR/SDKPackage\_OGLES/TrainingCourse/IntroducingPVRShell/OGLES/build/andro  
id/obj/local/armeabi/objs/PVRShell/Shell/OS/AndroidJNI/PVRShellOS.o:D:/PowerVR/S

dont mind the last few characters, that is just because I am developing under Japanese Windows.  
  
Thank you for any help.

Hi,

&nbsp;
  

Removing the extra definition of \_\_dso\_handle from /Shell/OS/AndroidJNI/PVRShellOS.cpp (it'll be near the top)&nbsp;should fix this and not cause any side effects. Out of curiosity which version of the Android NDK are you using as I haven't seen this error locally when building the Android SDK?
  

&nbsp;
  

Thanks,
  

&nbsp;
  

Scott

Thanks, Scott.  
That solved the problem.  
I am using ndk-r6b if that can be of any information to you.  
Thanks again.
