如何在Eclipse IDE中添加编译器选项 [英] How to add compiler options in Eclipse IDE

问题描述

我正在创建一个与天气API交互的应用程序，为此，我正在使用Poco的HTTPClientSession库，但是在编译时却遇到了错误

I'm creating an application that interfaces with a weather API, and to do so I'm using Poco's HTTPClientSession library, but I'm getting an error at compile time

Undefined symbols for architecture x86_64:
"Poco::Net::HTTPRequest::setHost(std::__1::basic_string<char,std::__1::char_traits<char>, std::__1::allocator<char> > const&)", referenced from:
  Weather::getCSV() in Weather.o
"Poco::Net::HTTPRequest::HTTPRequest()", referenced from:
  Weather::getCSV() in Weather.o
"Poco::Net::HTTPRequest::~HTTPRequest()", referenced from:
  Weather::getCSV() in Weather.o
"Poco::Net::HTTPResponse::HTTPResponse()", referenced from:
  Weather::getCSV() in Weather.o
"Poco::Net::HTTPResponse::~HTTPResponse()", referenced from:
  Weather::getCSV() in Weather.o
"Poco::Net::HTTPClientSession::sendRequest(Poco::Net::HTTPRequest&)", referenced from:
  Weather::getCSV() in Weather.o
"Poco::Net::HTTPClientSession::HTTPClientSession(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&, unsigned short)", referenced from:
  Weather::getCSV() in Weather.o
"Poco::Net::HTTPClientSession::~HTTPClientSession()", referenced from:
  Weather::getCSV() in Weather.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

从我的研究中我知道，此错误是由调用编译器时需要使用选项-lPocoNet引起的，但是我使用的是eclipse IDE，因此我不确定如何在实现该效果的同时使用日食

I know from my research that this error is caused by a need for the option -lPocoNet to be used when calling the compiler, but I use the eclipse IDE, so I'm not sure how to implement the same effect while using eclipse

推荐答案

如果使用的是gcc，则可以转到Project \ Properties

If you are using gcc, you can go to Project \ Properties

在属性对话框中，转到"C/C ++ Build \设置\ GCC C ++编译器\其他"，

In the properties dialog box, go to C/C++ Build\ Settings\GCC C++ Compiler\ Miscellaneous,

，然后将-lPocoNet添加到其他标志"，如下所示.

and add -lPocoNet to "Other flags" as shown below.
