Hello all,

I’m having trouble building a working set of boost libs for Android with NDK r12b.  I can build them but when the app runs there is an error when loading libgnustl_shared.so;

dlopen failed: cannot locate symbol "__gnu_thumb1_case_shi" referenced by "/data/app/com.companyname.app/lib/arm/libboost_system.so"

Is this a problem with how I've built the library?

this symbols appears to be used when code is built with thumb1 mode with
space optimization. It should be provided by GCC runtime library. Therefore, I have two guesses:

- Your application is not using thumb mode, but your build of Boost is
- There is mismatch between NDK used to build boost and your app.

Could you look into these options?
