我創建了一個使用RTTI支持dynamic_cast的應用程序。我在Application.mk文件中添加了「APP_CPPFLAGS + = -frtti」,但是我得到錯誤:「未定義對`vtable for ...」的引用。如果我不使用RTTI,我得到的錯誤:「錯誤:‘dynamic_cast的’與不允許 - FNO-RTTI」對RTTI支持的'vtable for ...的未定義引用

有輸出我得到:

./obj/local/armeabi-v7a/objs/vnptsofthsm/VNPTCASoftHSM/botan_impl/global_rng.o: In function `~RandomNumberGenerator': 
    D:\Duongpd\Token\TMS\vnpt.example.TestSoftHSM/jni/VNPTCASoftHSM/botan_impl/../botan/../botan/rng.h:90: undefined reference to `vtable for Botan::RandomNumberGenerator'

這裏是牡丹: :RandomNumberGenerator:

class RandomNumberGenerator 
    { 
    public: 

     static RandomNumberGenerator* make_rng(); 

     virtual void randomize(byte output[], size_t length) = 0; 

     SecureVector<byte> random_vec(size_t bytes) 
     { 
     SecureVector<byte> output(bytes); 
     randomize(&output[0], output.size()); 
     return output; 
     } 

     byte next_byte(); 

     virtual bool is_seeded() const { return true; } 

     virtual void clear() = 0; 

     virtual std::string name() const = 0; 

     virtual void reseed(size_t bits_to_collect) = 0; 

     virtual void add_entropy_source(EntropySource* source) = 0; 

     virtual void add_entropy(const byte in[], size_t length) = 0; 

     RandomNumberGenerator() {} 
     virtual ~RandomNumberGenerator() {} 
    private: 
     RandomNumberGenerator(const RandomNumberGenerator&) {} 
     RandomNumberGenerator& operator=(const RandomNumberGenerator&) 
     { return (*this); } 
    }; 

我Application.mk:

APP_STL := gnustl_static 
APP_CPPFLAGS += -fexceptions 
APP_CPPFLAGS += -frtti 
APP_CPPFLAGS += -DANDROID 
APP_ABI := armeabi-v7a 

你能幫助我嗎?

Here人們成功構建了Android的botan庫。請注意,他們使用了較舊的NDK,並且根本沒有rtti選項。最有可能的是,你也不需要它。

他用NDK工具鏈R5b構建了植物圖書館,支持RTTI,但他沒有在他的Application.mk fie中使用它。謝謝! – ChenHuang

那麼,你打算在沒有RTTI的情況下重建你的項目嗎? –

是的,這意味着我不會在Android的botan中使用dynamic_cast,需要重寫某些內容。謝謝你的幫助! – ChenHuang
