链接库和GTK +的问题

当尝试使用Code :: Blocks编译时,出现了GTK +的例子:

#include stdlib.h
#include gtk/gtk.h

static void helloWorld (GtkWidget *wid, GtkWidget *win)
{
  GtkWidget *dialog = NULL;

  dialog = gtk_message_dialog_new (GTK_WINDOW (win), GTK_DIALOG_MODAL, GTK_MESSAGE_INFO, GTK_BUTTONS_CLOSE, "Hello World!");
  gtk_window_set_position (GTK_WINDOW (dialog), GTK_WIN_POS_CENTER);
  gtk_dialog_run (GTK_DIALOG (dialog));
  gtk_widget_destroy (dialog);
}

int main (int argc, char *argv[])
{
  GtkWidget *button = NULL;
  GtkWidget *win = NULL;
  GtkWidget *vbox = NULL;

  /* Initialize GTK+ */
  g_log_set_handler ("Gtk", G_LOG_LEVEL_WARNING, (GLogFunc) gtk_false, NULL);
  gtk_init (&argc, &argv);
  g_log_set_handler ("Gtk", G_LOG_LEVEL_WARNING, g_log_default_handler, NULL);

  /* Create the main window */
  win = gtk_window_new (GTK_WINDOW_TOPLEVEL);
  gtk_container_set_border_width (GTK_CONTAINER (win), 8);
  gtk_window_set_title (GTK_WINDOW (win), "Hello World");
  gtk_window_set_position (GTK_WINDOW (win), GTK_WIN_POS_CENTER);
  gtk_widget_realize (win);
  g_signal_connect (win, "destroy", gtk_main_quit, NULL);

  /* Create a vertical box with buttons */
  vbox = gtk_vbox_new (TRUE, 6);
  gtk_container_add (GTK_CONTAINER (win), vbox);

  button = gtk_button_new_from_stock (GTK_STOCK_DIALOG_INFO);
  g_signal_connect (G_OBJECT (button), "clicked", G_CALLBACK (helloWorld), (gpointer) win);
  gtk_box_pack_start (GTK_BOX (vbox), button, TRUE, TRUE, 0);

  button = gtk_button_new_from_stock (GTK_STOCK_CLOSE);
  g_signal_connect (button, "clicked", gtk_main_quit, NULL);
  gtk_box_pack_start (GTK_BOX (vbox), button, TRUE, TRUE, 0);

  /* Enter the main loop */
  gtk_widget_show_all (win);
  gtk_main ();
  return 0;
}

我收到以下错误:

ld.exe||cannot find -lgobject-2.0|
ld.exe||cannot find -lglib-2.0|
||=== Build finished: 2 errors, 0 warnings ===|

我已将两者都链接到该项目,但我找不到让它工作的方法。我已经尝试了来自http://www.gtk.org/download-windows.html的捆绑和分离的包。我很确定它必须是简单/愚蠢的东西,但我找不到任何可以帮助我解决这个问题的东西。

答案 0 :(得分:2)

您是否已将包含libglib-2.0.a,libgobject-2.0.a文件的GTK目录添加到链接器搜索目录。
这可以通过以下路径完成:
Settings | Compiler and debugger... | Search directories | Linker | Add 即可。

可以在Build Log窗口中查看编译器/链接器的完整命令行。要启用此功能,请转到:
Settings | Compiler and debugger... | Other Settings | Compiler logging | Full command line

我没有遇到丢失的入口点问题,所以也许你的GTK副本已损坏。从GTK+ 2.22

下载一体化软件包

确保在Search directories | Compiler

中添加所有包含目录

作为附注,您可能需要使用-mms-bitfields编译项目,可以将其添加到: Settings | Compiler and debugger... | Other options 只需按原样粘贴标记。

当code :: blocks运行ld.exe而不是调用它时,例如:-l glib-2.0它正在调用它-lglib-2.0

在code :: block的链接器选项中的lib名称之前添加一个空格应该修复它。
