clang -Wall hwserver.c -o hwserver

给我一个错误：

我不是最有经验的C.不知道如果我确定添加一个编译器标志为zmq dylib或头或我的$PATH关闭.

在/usr/local / lib中：

libzmq.3.dylib
libzmq.a
libzmq.dylib
libzmq.la

并在/usr/local / include：

zmq.h
zmq_utils.h

和echo $PATH：

/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/lib/:/usr/local/include/
