gtk编译问题

我的cygwin是完全安装，a.c文件内容是gtk.org的hello world，应该没有错误的
#include <gtk/gtk.h>

/* This is a callback function. The data arguments are ignored
* in this example. More on callbacks below. */
static void hello( GtkWidget *widget,
               gpointer data )
{
g_print ("Hello World\n");
}

static gboolean delete_event( GtkWidget *widget,
                           GdkEvent  *event,
                           gpointer data )
{
/* If you return FALSE in the "delete_event" signal handler,
   * GTK will emit the "destroy" signal. Returning TRUE means
   * you don't want the window to be destroyed.
   * This is useful for popping up 'are you sure you want to quit?'
   * type dialogs. */

g_print ("delete event occurred\n");

/* Change TRUE to FALSE and the main window will be destroyed with
   * a "delete_event". */

return TRUE;
}

/* Another callback */
static void destroy( GtkWidget *widget,
                  gpointer data )
{
gtk_main_quit ();
}

int main( int argc,
      char *argv[] )
{
/* GtkWidget is the storage type for widgets */
GtkWidget *window;
GtkWidget *button;

/* This is called in all GTK applications. Arguments are parsed
   * from the command line and are returned to the application. */
gtk_init (&argc, &argv);

/* create a new window */
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);

/* When the window is given the "delete_event" signal (this is given
   * by the window manager, usually by the "close" option, or on the
   * titlebar), we ask it to call the delete_event () function
   * as defined above. The data passed to the callback
   * function is NULL and is ignored in the callback function. */
g_signal_connect (G_OBJECT (window), "delete_event",
      G_CALLBACK (delete_event), NULL);

/* Here we connect the "destroy" event to a signal handler.
   * This event occurs when we call gtk_widget_destroy() on the window,
   * or if we return FALSE in the "delete_event" callback. */
g_signal_connect (G_OBJECT (window), "destroy",
      G_CALLBACK (destroy), NULL);

/* Sets the border width of the window. */
gtk_container_set_border_width (GTK_CONTAINER (window), 10);

/* Creates a new button with the label "Hello World". */
button = gtk_button_new_with_label ("Hello World");

/* When the button receives the "clicked" signal, it will call the
   * function hello() passing it NULL as its argument.  The hello()
   * function is defined above. */
g_signal_connect (G_OBJECT (button), "clicked",
      G_CALLBACK (hello), NULL);

/* This will cause the window to be destroyed by calling
   * gtk_widget_destroy(window) when "clicked".  Again, the destroy
   * signal could come from here, or the window manager. */
g_signal_connect_swapped (G_OBJECT (button), "clicked",
      G_CALLBACK (gtk_widget_destroy),
                           G_OBJECT (window));

/* This packs the button into the window (a gtk container). */
gtk_container_add (GTK_CONTAINER (window), button);

/* The final step is to display this newly created widget. */
gtk_widget_show (button);

/* and the window */
gtk_widget_show (window);

/* All GTK applications must have a gtk_main(). Control ends here
   * and waits for an event to occur (like a key press or
   * mouse event). */
gtk_main ();

return 0;
}

编译命令是：
gcc -Wall -g a.c -o a.exe `pkg-config --cflags gtk+-2.0` `pkg-config --libs gtk+-2.0`
错误提示是：
a.c:98:2: warning: no newline at end of file
同样的命令在fc系统里却没事，怎么回事呀？

警告，不是错误

但程序编译后有个a.exe,在cygwin里不能运行呀.
莫非我还要装WIN版的运行环境,CYGWIN里应该有的呀!!!

郁闷.....

mozilla · 发表于 2004-12-26 12:43:23

运行出什么错？

zzh2004linux · 发表于 2004-12-26 19:05:49

<a:2796>: gtk-warning **: cannot open display:

mozilla · 发表于 2004-12-26 22:20:43

噢，要在X环境中运行。

zzh2004linux · 发表于 2004-12-27 17:42:57

我就在 cygwin里编译运行呀，我没用cmd里弄呀,如果CYGWIN里还不是X环境，那什么才是X环境呀？？？

mozilla · 发表于 2004-12-27 20:02:25

cygwin也有X，好像也是startx

我倒!好麻烦,如果我发布我的程序该怎么办,难道把2G的cygwin也发布吗?

有没有更简单的方法呀?

DexterK · 发表于 2004-12-27 23:03:51

直接用linux吧
省得烦。

有win32版的gtk+

可以在dev-c++里用

zzh2004linux · 发表于 2004-12-28 08:40:42

我想写跨平台程序呀,所以用GTK,如果用CYGWIN,网络方面很方便可以用NETINET,但GTK不能用自带的,如果用DEV,GTK是能弄好但网络方面用什么呢?NETINET没有,用GLIBC,它只能在LINUX下用,天哪............好累呀

mozilla · 发表于 2004-12-28 11:01:21

glibc本来就是跨平台的

zzh2004linux · 发表于 2004-12-28 12:55:35

刚才下了一个,需要configure命令配置呀,dev没有这东西,而且解压缩,还提示有重名的文件,是否覆盖,我晕.....

mozilla · 发表于 2004-12-28 14:05:27

glibc源码里有configure呀
