我是一名java开发人员,编译一些C ++代码来构建一个共享对象,以便用Java访问它。我可以成功构建我的'so'文件但是当我使用Java加载它时出现undefined symbol: _ZTI18TransportFormatter
错误。我在代码中为这个符号做了一个grep,我发现符号是TcpFormatter.o and UdpFormatter.o
的一部分。以下是我的make文件。如果我在这里丢失任何东西,请告诉我。
P.S:我正在ARM处理器上构建它。当我构建它并在常规的Linux x86上运行时,我没有问题。
先谢谢。

答案 0 :(得分:1)
只是一个有根据的猜测,但看起来你的代码使用RTTI(_ZTI18TransportFormatter = typeinfo for TransportFormatter),或者直接通过调用dynamic_cast
或typeid
,或者编译器/链接器无论如何都会包含它不要通过-fno-rtti
选项明确禁用它,但这通常在嵌入式平台上不可用。
