I am having trouble implementing a gtkmm application's makefile. I have implemented a simple solution, however, I am getting the following error:
g++ -Wall -std=c++11
pkg-config gtkmm-3.0 --cflags
-c main.cppcc main.o
pkg-config gtkmm-3.0 --libs
-o main/usr/bin/ld: main.o: undefined reference to symbol '__gxx_personality_v0@@CXXABI_1.3'

Glib::RefPtr<Gtk::Application> app = Gtk::Application::create(argc, argv, "org.gtkmm.examples.base");
MainWindow window;
// Show windows and return when closed
return app->run(window);
}
MainWindow.hpp:
#ifndef GUI_MAIN_WINDOW_H
#define GUI_MAIN_WINDOW_H
#include <gtkmm.h>
class MainWindow: public Gtk::Window {
public:
MainWindow();
virtual ~MainWindow();
protected:
Gtk::Frame frame;
};
#endif // GUI_MAIN_WINDOW_H
MainWindow.cpp:
#include "MainWindow.hpp"
MainWindow::MainWindow() {
// Set window properties
set_title("Main window");
set_size_request(300, 300);
// Set window border width
set_border_width(10);
// Add frame
add(frame);
// Set frame's label
frame.set_label("Frame");
// Align the label at the right of the frame
frame.set_label_align(Gtk::ALIGN_END, Gtk::ALIGN_START);
// Set the style of the frame
frame.set_shadow_type(Gtk::SHADOW_ETCHED_OUT);
show_all_children();
}
MainWindow::~MainWindow() {
// Nothing to do here
}
What am I doing wrong?
I met the same issue when built openCV libraries
$ gcc DisplayImage.cpp `pkg-config opencv --libs --cflags` -o DisplayImage
/usr/bin/ld: /tmp/ccbyJ7Ms.o: undefined reference to symbol '_ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEED1Ev@@GLIBCXX_3.4.21'
//usr/lib/i386-linux-gnu/libstdc++.so.6: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
[SOLVE]
For gcc try adding -lstdc++
to your command.
$ gcc DisplayImage.cpp `pkg-config opencv --libs --cflags` -o DisplayImage -lstdc++
For g++ it will link libstdc.so.6++ automatically
$ g++ DisplayImage.cpp `pkg-config opencv --libs --cflags` -o DisplayImage
