Problem upgrading from ndk version r5b to r7b

[Discordia]

Hey

I have been staying on 5b for a long time and thought it was time to upgrade, but when I try to compile I get the error:

error: cannot use typeid with -fno-rtti 

when I include STL classes (example: shard_ptr.hpp from the tr1 namespace).

The full log:

This might be related to this entry in the NDK r7b Changelog:

- When your application uses the GNU libstdc++ runtime, the compiler will

  no longer forcibly enable exceptions and RTTI. This change results in smaller

  code. If you need these features, you need to do either one of these:

     1/ Enable exceptions and/or RTTI explicitely in your modules or

        Application.mk. (recommended)

     2/ Define APP_GNUSTL_FORCE_CPP_FEATURES to 'exceptions', 'rtti' or both

        in your Application.mk. See docs/APPLICATION-MK.html for more details.

Hope this helps

Fixed in 4.5, so until the compiler is upgraded, you either need to enable rtti or modify your headers to use shared_ptr.
