Cpp-netlib抱怨缺少lboost-thread

cpp-netlib complains about missing lboost-thread

我正在学习cpp-netlib，并尝试运行官方网站上给出的示例客户端。代码非常简单:

#include <boost/network/protocol/http/client.hpp>
#include <iostream>
int main(int argc, char *argv[]) {
    using namespace boost::network;
    if (argc != 2) {
        std::cout << "Usage: " << argv[0] << " [url]" << std::endl;
        return 1;
    }
    http::client client;
    http::client::request request(argv[1]);
    request << header("Connection", "close");
    http::client::response response = client.get(request);
    std::cout << body(response) << std::endl;
    return 0;
}

下面是这个c++应用程序的makefile:CC =c++ -std=c++11

CFLAG = -I/usr/local/Cellar/boost/1.57.0/include
LIBFLAG = -L/usr/local/Cellar/boost/1.57.0/lib  
all: client
client: client.o
    $(CC) $(LIBFLAG) -lboost_system -lboost_thread client.o -o client  
client.o: client.cpp
    $(CC) -c $(CFLAG) client.cpp
clean:
    rm -rf *.o client

它抱怨编译后找不到lboost_thread库:

ld: library not found for -lboost_thread
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [client] Error 1

在我的boost库目录中，boost_thread库显示如下:

libboost_thread-mt.a      libboost_thread-mt.dylib

为什么不能找到这个库?我在链接上有什么错误吗?

尝试更改makefile以链接到-lboost-thread-mt而不是-lboost-thread。

由于某些原因，您似乎缺少libboost_thread
