[Compiling Error] tbb_allocator.h has errors.

[Hawx_Chen]

Hi, Sirs, I met problems when compiling NDK within TBB over MAC platform.

May I ask you give me some advices?  I want to know the root causes very much.

Thank you.

hello, could you try to change the c++ library? 

APP_STL:=stlport_shared

to

APP_STL:=gnustl_shared

First of all,  I have to thank you, Vladimir. 

I just tried Vladimir's comment.

• ​Application.m

APP_ABI := armeabi armeabi-v7a
APP_STL := gnustl_shared
APP_GNUSTL_FORCE_CPP_FEATURES := exceptions rtti

It shows another errors:

I had similar problem. You need to remove lines 17-20 (libgnustl_shared stuff) from  jni/Android.mk. 

libgnustl_shared.so should be picked up by "APP_STL := gnustl_shared" clause in Application.mk and copied to the folder next to your hello-jni library. and do not forget to load libraries in correct order in the java code.

[java]
        System.loadLibrary("gnustl_shared");
        System.loadLibrary("tbb");
        System.loadLibrary("hello-jni");

[/java]

BTW our latest development release contains tachyon example (<root>\examples\parallel_for\tachyon\android) that can be built for all architectures and it should show the path where it expects to see architecture-specific libtbb.so library.

And BTW, there is a tutorial how to create apps with intel tbb library for android.
