c++ - 为什么我不能使用 MinGW 编译 GTK+？

Question

帮助我使用 Stackoverflow!

所以，我觉得我已经正确设置了我的环境，但是我无法构建我的程序!

#include <cstdlib>
#include <stdio.h>
#include <stdlib.h>
#include <gtk/gtk.h>

using namespace std;

/*
* simple gtk application
* author jan bodnar
* date february 17, 2008
*/

int main(int argc, char** argv) {

GtkWidget *window;
gtk_init(&argc, &argv);

window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
gtk_window_set_default_size(GTK_WINDOW(window), 200, 100);
gtk_window_set_title(GTK_WINDOW(window), "gtkapp");
gtk_widget_show(window);

g_signal_connect(window, "destroy",
  G_CALLBACK (gtk_main_quit), NULL);

gtk_main();

return (EXIT_SUCCESS);
}

我从这个命令生成了包含目录的列表:pkg-config --cflags gtk+-2.0

然后我在 netbeans 的 C++ 编译器设置中添加了包含文件...

我的包含目录:

../gtk/include/gtk-2.0../gtk/lib/gtk-2.0/include../gtk/include/atk-1.0../gtk/include/cairo../gtk/include/pango-1.0../gtk/include/glib-2.0../gtk/lib/glib-2.0/include../gtk/include/libpng12

Then I generated a list of libs from this command: pkg-config --libs gtk+-2.0

Then added my libs to the linker command line in netbeans with this:


-LC:/tools/gtk/lib -lgtk-win32-2.0 -lgdk-win32-2.0 -latk-1.0 -lgio-2.0 -lgdk_pixbuf-2.0 -lpangowin32-1.0 -lgdi32 -lpangocairo-1.0 -lpango-1.0 -lcairo -lgobject-2.0 -lgmodule-2.0 -lglib-2.0 -lintl


But still I cannot compile a simple program! I must be missing something stupid, but I cannot for the life of me figure it out.

#
#  There exist several targets which are by default empty and which can be 
#  used for execution of your targets. These targets are usually executed 
#  before and after some main targets. They are: 
#
#     .build-pre:              called before 'build' target
#     .build-post:             called after 'build' target

您的程序可以编译，但不能链接。问题是，由于您必须包含所有目录以包含所有 header ，因此您还必须指明库的目录。总结一下:问题是 netbeans 无法找到要链接的库。

在您的项目中，转到“属性”、“链接”，然后在“其他库目录”中，您必须提及包含 Gtkmm 分发中的库的所有目录。

希望这对您有所帮助。
