在linux下用eclipse开发c++程序时出错,找不到include文件
我用的是Red Hat Fedroa Core3+gtkmm+eclipse+CDT,装好了以后建立Managed C++ Project,文件如下
helloworld.h:
#ifndef GTKMM_EXAMPLE_HELLOWORLD_H
#define GTKMM_EXAMPLE_HELLOWORLD_H
#include <gtkmm/button.h>
#include <gtkmm/window.h>
class HelloWorld : public Gtk::Window
{
public:
HelloWorld();
virtual ~HelloWorld();
protected:
//Signal handlers:
virtual void on_button_clicked();
//Member widgets:
Gtk::Button m_button;
};
#endif // GTKMM_EXAMPLE_HELLOWORLD_H
helloworld.cxx:
#include "helloworld.h"
#include <iostream>
HelloWorld::HelloWorld()
: m_button("Hello World") // creates a new button with the label "Hello World".
{
// Sets the border width of the window.
set_border_width(10);
// When the button receives the "clicked" signal, it will call the
// on_button_clicked() method. The on_button_clicked() method is defined below.
m_button.signal_clicked().connect(sigc::mem_fun(*this, &HelloWorld::on_button_clicked));
// This packs the button into the Window (a container).
add(m_button);
// The final step is to display this newly created widget...
m_button.show();
}
HelloWorld::~HelloWorld()
{
}
void HelloWorld::on_button_clicked()
{
std::cout << "Hello World" << std::endl;
}
main.cxx:
#include <gtkmm/main.h>
#include "helloworld.h"
int main (int argc, char *argv[])
{
Gtk::Main kit(argc, argv);
HelloWorld helloworld;
Gtk::Main::run(helloworld); //Shows the window and returns when it is closed.
return 0;
}
编译的时候说找不到头文件gtkmm/main.h,gtkmm/button.h,gtkmm/window.h,但是可以找到<iostream>,这是为什么?
