Poco错误

Question

我想在我的C++项目中使用Poco库。但我在编译上出了个错误。

我正在Ubuntu上开发，CLion 1.2.4IDE

这里是我的源代码：

#include "Poco/Net/ServerSocket.h"
#include <iostream>

int main(int arc, char** argv){
    std::cout << "Hello world!";
    return 0;
}

这是我的CMakeLists.txt文件：

cmake_minimum_required(VERSION 3.3)
project(rcp)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

set(SOURCE_FILES main.cpp)

set(CMAKE_RUNTIME_OUTPUT_DIRECTORY "${CMAKE_CURRENT_SOURCE_DIR}/bin")

include_directories("libraries")

add_executable(rcp ${SOURCE_FILES})

target_link_libraries(rcp pthread PocoNet PocoUtil PocoFoundation)

这就是我做编译时的输出：

CMakeFiles/rcp.dir/main.cpp.o: In function `Poco::Net::Impl::IPv6SocketAddressImpl::host() const':
main.cpp:(.text._ZNK4Poco3Net4Impl21IPv6SocketAddressImpl4hostEv[_ZNK4Poco3Net4Impl21IPv6SocketAddressImpl4hostEv]+0x11): undefined reference to `Poco::Net::IPAddress::IPAddress(void const*, unsigned int, unsigned int)'

我的问题在哪里，我今天一直在搜索，但我找不到任何东西，请帮助我解决这个问题。

谢谢大家

我解决了这个问题，作为上面评论中的“M.M”指南：

输出结果表明，您实际上并没有链接到Poco::Net。另一种可能是，如果您使用的Poco头来自不同版本的Poco，而不是您要链接的编译库

我删除了将包含更改为包含正确的库。

一开始这是我的包括线：

#include "Poco/Net/ServerSocket.h"

变到

#include <Poco/Net/ServerSocket.h>

现在一切都很好。

谢谢M.M .
