java - ZMQ-libzmq.so.3 : cannot open shared object file: No such file or directory

Question

我正在尝试将 zeroMQ 嵌入到我的应用程序中，我遵循了 this guideline安装 ZMQ，所以到这里一切正常。我的应用程序中有这行代码:

ZMQ.Context m_context = ZMQ.context(1);

但上面的代码行引发了以下异常:

Exception in thread "main" java.lang.UnsatisfiedLinkError: /tmp/libjzmq-812339378390536247.lib: libzmq.so.3: cannot open shared object file: No such file or directory

错误恰好指向this line .

P.S:要完全解释这个问题有点困难。如果您有任何问题，请告诉我。谢谢。

如果您已经按顺序成功构建了 libzmq 和 jzmq，我会运行:

$ sudo ldconfig

更新系统库缓存。然后我会检查 LD_LIBRARY_PATH 是否像 Raffian 提到的那样定义，或者将您的库路径明确设置为类似:

$ java -Djava.library.path=/usr/lib:/usr/local/lib
