關(guān)于GTK+/Framebuffer編譯問(wèn)題�。。。。。。。。�

nkuzy

<<<問(wèn)題一>>>
要在ARM926EJ上使用GTK+，主要是手機(jī)方案，請(qǐng)問(wèn)題大家用那種方案比較合適：
1. GTK+/Tiny-x
2. GTK+/DirectFB
3. GTK+/Framebuffer
方案3會(huì)不會(huì)更簡(jiǎn)潔高效一些

我個(gè)人傾向方案3，按照GTK+ Reference Manual(http://developer.gnome.org/doc/API/2.0/gtk/index.html)在SUSE上編譯X86版進(jìn)行試驗(yàn)的時(shí)候發(fā)生問(wèn)題：
STEP1.我首先把GTK+/X11 編譯成功，而且運(yùn)行Demo正常。
STEP2.然后我想試試GTK+/Framebuffer，于是我先安裝了freetype-2.3.0.tar.gz，在重新編譯GTK+ ，
  但在./configure --prefix=/opt/gtk --with-gdktarget=linux-fb 時(shí), 最后幾行顯示：

config.status: gdk/gdkconfig.h is unchanged
configuration:
        target: linux-fb
Warning: The linux-fb GDK target is unmaintained
         and may not work or even compile

<<<問(wèn)題二>>>
請(qǐng)問(wèn)這個(gè)Warning是什么造成的？？？？？？？？？？？？？

STEP3.我忽略此Warning，繼續(xù)編譯GTK，發(fā)生錯(cuò)誤：

In file included from gdkprivate-fb.h:41,
                 from gdkcolor-fb.c:34:
/opt/gtk/include/ft2build.h:56:38: error: freetype/config/ftheader.h: No such file or directory
In file included from gdkcolor-fb.c:34:

<<<問(wèn)題三>>>
這個(gè)錯(cuò)誤怎么回事兒？？
在我Linux目錄中有/opt/gtk/include/freetype2/freetype/config/ftheader.h

STEP4：我把freetype這個(gè)目錄復(fù)制到/opt/gtk/include/ ，然后重新編譯，又出現(xiàn)問(wèn)題：
gdkdrawable-fb2.c: In function 'gdk_fb_clip_region':
gdkdrawable-fb2.c:454: warning: passing argument 1 of '_gdk_gc_get_clip_region' from incompatible pointer type

<<<問(wèn)題四>>>
�。。。。。。。。。。。。〔恢�道怎么回事，請(qǐng)各位幫幫忙？？？？？？？？？？？

whyglinux

1. Cann't help you since no experience.

2. linux-fb is "obsolete", and the linux-fb GDK target is unmaintained (不再被維護(hù)), therfore "may not work or even compile" on this GTK+ version (2.10.6). Ignore it.

3. 在安裝了 freetype 之后是否重新配置、編譯、更新了 pango？否則，有可能參考的仍然是舊版本的 freetype。

4. 先解決問(wèn)題 3。

我也遇到了和你差不多的問(wèn)題，QQ：178056974

以前也用過(guò)gtkFB , 但是　gtk 似乎 2.2 以后就很少更新　framebuffer 了，現(xiàn)在FB徹底放棄了，改用directfb了．現(xiàn)在gtk已經(jīng)把　directfb 代碼加進(jìn)去了．
對(duì)于 gtk 你只有　１，２　可選

spmno

是啊，GTKFB被放棄了，還得另想辦法了。呵呵。

3 老早不用了吧

手機(jī)的話, 還是用1 gtk+tinyx吧. dfb快是快, 幾個(gè)應(yīng)用同時(shí)跑起來(lái), 畫(huà)屏就危險(xiǎn)了

dfb 只是在 x86 上有限的幾種顯卡上快。

dfb 是方向。

用gcc -o helloworld hello.c `pkg-config --cflags --libs gtk+-2.0`編譯hello.c發(fā)生如下錯(cuò)誤：              from hello.c:1:
/usr/include/bits/local_lim.h:39: fatal error: linux/limits.h: No such file or directory
compilation terminated.試了很多方法都不行。求救！源代碼如下：
#include<gtk-2.0/gtk/gtk.h>
void hello(GtkWidget *widget,gpointer data)
{
      g_print("Hello 大家好\n");
}
gint delete_event(GtkWidget *widget,GdkEvent *event,gpointer data)
{
      g_print ("delete event occurred\n");
     return(TRUE);
}
void destroy(GtkWidget *widget,gpointer data)
{
      gtk_main_quit();
}
int main( int argc, char *argv[] )
{
      GtkWidget *window;
      GtkWidget *button;
      gtk_init (&argc, &argv);
      window=gtk_window_new (GTK_WINDOW_TOPLEVEL);
      gtk_signal_connect (GTK_OBJECT(window),"delete_event",GTK_SIGNAL_FUNC(delete_event),NULL);
      gtk_signal_connect (GTK_OBJECT (window), "destroy",GTK_SIGNAL_FUNC (destroy), NULL);
      gtk_container_set_border_width (GTK_CONTAINER (window), 10);
      button = gtk_button_new_with_label ("Hello 大家好");
      gtk_signal_connect (GTK_OBJECT (button), "clicked",GTK_SIGNAL_FUNC (hello), NULL);
      gtk_signal_connect_object (GTK_OBJECT (button), "clicked",GTK_SIGNAL_FUNC(gtk_widget_destroy),GTK_OBJECT (window));
      gtk_container_add (GTK_CONTAINER (window), button);
      gtk_widget_show (button);
      gtk_widget_show (window); /*顯示一個(gè)窗口*/
      gtk_main(); /*進(jìn)入主循環(huán)*/
      return(0);
}
頭文件剛開(kāi)始是這樣的：<gtk/gtk.h>安裝gtk都是按照別人成功案例安裝的。
