我正在尝试安装rpclib并将其用于我的项目中。我使用指令here安装了该库，安装后，可以在/usr/local/include中看到头文件，在librpc.a中看到一个/usr/local/lib文件。但是，当我尝试编译以下代码时：
#include <iostream>
#include <rpc/server.h>
int main(){
rpc::server srv(8080);
return 0;
}
它给了我以下错误：
Undefined symbols for architecture x86_64:
"rpc::server::server(unsigned short)", referenced from:
_main in ccRtP1PN.o
"rpc::server::~server()", referenced from:
_main in ccRtP1PN.o
ld: symbol(s) not found for architecture x86_64
collect2: error: ld returned 1 exit status
如果我不调用rpc::server srv(8080);，则可以正确编译程序（编译器可以找到头文件！）。我正在使用以下程序编译程序：
g++ main.cpp
我也尝试过：
g++ main.cpp -L /usr/local/lib
他们给我同样的错误。我的系统环境如下：
操作系统：macOS 10.14.3
CMake： v3.13.4
g ++（GCC）： v8.1.0
我知道链接器找不到函数的定义是一个问题。但是听起来源文件和头文件在正确的位置。我尝试将#include <rpc/server.h>替换为#include "rpc/server.h"。我还尝试了几次卸载并安装它。但是问题仍然存在。
有人可以帮我弄清楚如何解决此问题吗？非常感谢！
更新
我尝试使用以下命令链接librpc：
g++ main.cpp -lrpc
它给了我以下错误：
