在linux下用eclipse开发c++程序时出错，找不到include文件

[bbhl80]

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？

第一，可能没有安装sdk
第二，你的编译器没有指定include的编译参数。

会不会是没有安装GTK的SDK 包?
