Ndk R5 supports rtti

In the sources/cxx-STL/gnu-libstdc ++/readme file of ndk R5, it says:

To use it, define app_stl to 'gnustl _ static 'in your application. mk. <br/> see Docs/CPLUSPLUS-SUPPORT.html for more details. <br/> This implementation fully supports C ++ exceptions and rtti. <br/>

That is to say, if we add the following in the application. mk file:

App_stl: = gnustl_static

 

You can use GNU libstdc ++. This version supports C ++ exception and rtti. (I tried stlport in ndk R5. rtti is not supported. If typeid is used, an error is returned)

 

Note: Android build system always includes the-fno-rtti compilation option, but if you specify app_stl as gnustl_static, it will automatically add a-frtti to you later, in this way, G ++ uses the last flag, so rtti is enabled.
