我正在尝试使用QtWebApp创建一个简单的Web应用程序服务器，但是它显示了一些错误，我无法弄清楚该如何解决，任何提示如何解决此问题？
这是我所做的：
=从http://stefanfrings.de/qtwebapp/下载QtWebApp-src.zip
=使用QtWebApp和qmake编译make，成功完成
=创建一个新的qwtest.pro，其中包含：
QT += core network
QT -= gui
TARGET = qwtest
CONFIG += console
CONFIG -= app_bundle
TEMPLATE = app
SOURCES += main.cpp
=创建源文件
main.cpp，其中包含：#include "../v1.3.2 2014-01-08/lib/bfHttpServer/src/httplistener.h"
#include <QtCore>
class MyController: public HttpRequestHandler {
private:
QCoreApplication *app;
public:
MyController(QCoreApplication *app) : app(app) {}
void service(HttpRequest& request, HttpResponse& response);
};
void MyController::service(HttpRequest& request, HttpResponse& response) {
QByteArray path=request.getPath();
QByteArray username=request.getParameter("username");
response.setHeader("Content-Type", "text/html; charset=ISO-8859-1");
response.setCookie(HttpCookie("myCookie","any value",600));
response.write("<html><body>");
response.write("Hello ");
response.write(username);
response.write("</body></html>");
}
int main(int argc, char *argv[]) {
QCoreApplication* app=new QCoreApplication(argc,argv);
QSettings* settings=new QSettings("configfile.ini",QSettings::IniFormat,app);
MyController* controller=new MyController(app);
HttpListener* listener=new HttpListener(settings,controller,app);
return app->exec();
}
=使用
qmake和make进行编译/home/foo/qtwebapp/build-QtWebApp-Desktop-Debug/../v1.3.2 2014-01-08/src/main.cpp:66: undefined reference to `Startup::Startup(int, char**)'

最佳答案
您的项目文件必须包含bfHttpServer类的源。看一下QtWebapp示例附带的项目文件，在那里您将看到如何包含它们。
include(lib/bfHttpServer/src/bfHttpServer.pri)
