我正在尝试将 Qt Creator 中的 poco 库与 poco 附带的示例之一一起使用,我已经让它在 Visual Studio 2012 中工作,但我一直在 Qt Creator 中遇到构建错误。我的 lib 路径中有 .dll 和 .lib。
这是我的 .pro 文件
TEMPLATE = app
CONFIG += console
CONFIG -= qt
SOURCES += main.cpp
INCLUDEPATH += C:\Users\justin\Downloads\poco-1.4.6\Net\include
INCLUDEPATH += C:\Users\justin\Downloads\poco-1.4.6\Foundation\include
win32:CONFIG(release, debug|release): LIBS += -L$$PWD/lib/ -lPocoFoundation
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/lib/ -lPocoFoundationd
INCLUDEPATH += $$PWD/
DEPENDPATH += $$PWD/
win32:CONFIG(release, debug|release): PRE_TARGETDEPS += $$PWD/lib/PocoFoundation.lib
else:win32:CONFIG(debug, debug|release): PRE_TARGETDEPS += $$PWD/lib/PocoFoundationd.lib
win32:CONFIG(release, debug|release): LIBS += -L$$PWD/lib/ -lPocoNet
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/lib/ -lPocoNetd
INCLUDEPATH += $$PWD/
DEPENDPATH += $$PWD/
win32:CONFIG(release, debug|release): PRE_TARGETDEPS += $$PWD/lib/PocoNet.lib
else:win32:CONFIG(debug, debug|release): PRE_TARGETDEPS += $$PWD/lib/PocoNetd.lib
这是.cpp文件
#include "Poco/URIStreamOpener.h"
#include "Poco/StreamCopier.h"
#include "Poco/Path.h"
#include "Poco/URI.h"
#include "Poco/Exception.h"
#include "Poco/Net/HTTPStreamFactory.h"
#include "Poco/Net/FTPStreamFactory.h"
#include <memory>
#include <iostream>
using Poco::URIStreamOpener;
using Poco::StreamCopier;
using Poco::Path;
using Poco::URI;
using Poco::Exception;
using Poco::Net::HTTPStreamFactory;
using Poco::Net::FTPStreamFactory;
int main(int argc, char** argv)
{
HTTPStreamFactory::registerFactory();
FTPStreamFactory::registerFactory();
try
{
URI uri("http://example.com");
std::auto_ptr<std::istream> pStr(URIStreamOpener::defaultOpener().open(uri));
StreamCopier::copyStream(*pStr.get(), std::cout);
}
catch (Exception& exc)
{
std::cerr << exc.displayText() << std::endl;
return 1;
}
return 0;
}
这些是构建错误:

undefined reference to `Poco::Net::FTPStreamFactory::registerFactory()'
undefined reference to `Poco::URI::URI(char const*)'
undefined reference to `Poco::URIStreamOpener::defaultOpener()'
