請問我可以成功的compile GTK on DirectFB, 然而在create 一個window 時有一個簡單window 出現, 但在畫一個button 時郤會失敗..請問您有遇過嗎??

不好意思，我後來覺得Gtk實在太麻煩，所以我改用FLTK來作我要的東西。

不過我有在我的平台上把它附的demo程式跑起來，看起來沒什麼問題，視窗元件都可以正常出現。或者你可能要review一下你的程式，也許是沒按照正正確的Gtk programming流程。

恩..只好再試試看囉..謝謝你^^

我根据DirectFB官方Wiki所说的，编译了一个arm的版本，但是在运行gtk-demo时，报错：
[root@Linux bin]#./gtk-demo

你能否给我一点建议，是不是需要做些配置。

Davis,
像這樣的錯誤很頭大啊，我找了一下發現像是發出signal 11/6這類的問題還不少，而且不一定是同一個源頭。我個人的感覺是GTK裡面相依的library太多了，可能是某些library版本之間不相容的問題。

雖然說我做出來的gtk-demo可以跑，可是我看那樣的環境也不能保證其他程式沒問題，所以後來就轉換到其他GUI了。

Hi, yk:

請問是環境變數沒設好or其他原因? 謝謝!!!

Jacky,
我手邊的GTK環境都清光了，暫時沒辦法看的很深入。不過從你貼的message來看，應該是DirectFB關於matrox的graphic driver跟你用的toolchain衝到了，如果matrox的支援不是很必要的話，看能不能從configure裡面把它關掉，像是 –without-gfxdrivers=matrox 這樣的option(我是猜的，不一定對)。

Hi, ykhuang:

You are right!
It’s due to improper gfx driver.
I just remove some default gfx driver and it can make sucessfully!
Thanks!

Hi, ykhuang :

我在build GTK+, 遇到以下error :
checking Pango flags… configure: error:
*** Pango not found. Pango built with Cairo support is required
*** to build GTK+. See http://www.pango.org for Pango information.

看起來是Pango沒有build with Cairo
但我下的config string:
./configure –host=arm-linux CC=arm-linux-gcc –prefix=/usr/local/gtk –with-x=no –enable-cario

請問你知道如何解嗎? thanks!

Jacky,

這不一定是你的Pango沒設定好，也有可能是Gtk configure根本就沒找到你系統裡面的Pango，因為他是用pkgconfig去搜尋的，所以你可以先手動試試看pkgconfig看能不能找到Pango，若是找不到Pango相關的.pc檔，你有可能需要設定pkgconfig路徑的環境變數讓configure可以搜尋的到。

hi,ykhuang,可以交流一下，在嵌入式linux下边，fltk如何移植吗？谢谢你

fyl,

今天剛好比較沒事，可能寫一點我個人的FLTK移植經驗

你好，我交叉编译了DirectFB+GTK，把生成的文件放在了开发板对应的文件夹里，
自己在pc上编译了一个gtk的程序，
放到arm开发板上运行，报错如下：
bash-2.05b# ./mhelloworld

楼上的Davis兄，可解决问题了
我的msn：freeubuntu@hotmail.com

freeubuntu,

Direct/Modules: Could not open module directory `/usr//lib/directfb-1.1-0/gfxdrivers’!
–> No such file or directory

看起來像是DirectFB沒設置或安裝好
後面的fontconfig雖然有錯，但可能不是致命的錯誤吧

freeubuntu兄，这个问题前段时间放下来了，还是没有解决呀，你有什么建议呀？

可能是fb_pan_display的问题。
我在三星2410的平台上移植gtk+directfb也碰到了类似问题，
我在内核中fb驱动里实现了一个空的pan_display函数（仅仅返回0），解决该问题。

Hi, gentleman,

Thank in advance!

Hi alanz,

The __ctype_b seems to exists in glibc. It could be missing in your glibc. Google says that glibc2.2 has that but not available in glibc2.3.2. Please check your glibc installation.

yk,

Hi Alanz,

I’m not quite sure if it’s an issue of DirectFB configure, maybe you can try to edit /etc/ld.so.conf and execute ldconfig again to see if it works.

hi : ykhuang
我抓了directfb 1.2.0版, 如果我要build for s3c2440 arm9, 需要下什麼參數及修改什麼嗎? 謝謝

smikid,

要不要照我的步驟三先編個最簡單的試試看？每個人的環境跟需求都不一樣，反覆嘗試修改都是免不了的。

hi : ykhuang
我build 好directfb 跟 directfb-example, load到開發板之後 run一個test出現以下訊息
/df_window: error while loading shared libraries: libdirectfb-1.0.so.0: cannot
open shared object file: No such file or directory
我是在sever上build, 所以prefix我是設我自己的目錄如 /home1/xxxx/usr, 在開發板上
我也是建立相同的目錄

謝謝

hi smikid,

執行時動態載入函式庫的路徑對嗎？先確認libdirectfb-1.0.so.0的路徑，然後透過設定LD_LIBRARY_PATH或修改ld.so.conf + ldconfig來確定程式執行時會去搜尋並載入函式庫。

hi ykhuang:
如果我把directfb build出來的lib放到/usr/lib下就可以run了, 所以是沒指定lib的path
謝謝

smikid,
是的，你可以照我上一則留言寫的，去修改ld.so.conf，把你要新增的library路徑加在最後面，然後執行一次ldconfig就行了。

Hi ykhuang,
我是需要移植gtk-directfb到mips平台上，我按照官方wiki在编译glibc2.16.0的时候，遇到
checking for iconv_open… no
checking for libiconv_open in -liconv… no
checking for iconv_open in -liconv… no
configure: error: *** No iconv() implementation found in C library or libiconv
这个问题。
libiconv gettext我都已经安装了。我想进去你上文所说的黑米的书签里看那篇文章，但是我打不开那个网页。
一下是config.log的错误记录：
#ifdef __cplusplus

collect2: ld returned 1 exit status

请问这个问题是什么原因呢？谢谢

原来是libiconv和gettext都需要用交叉编译器编译，再让glib去检测。libiconv搞好了，编译gettext-0.17却死活不过。
mbslen.c: In function ‘mbslen’:
mbslen.c:37: error: storage size of ‘iter’ isn’t known
mbslen.c:40: error: ‘mbstate_t’ undeclared (first use in this function)
make[4]: *** [mbslen.o] Error 1

Joei,
你這個iter跟mbstat的錯誤我遇過，不過不是在build GTK時碰上的，先從header files下手吧，先看看系統include裡面有沒有相關定義，如果沒有，也許gettext需要另一組kernel include

Hi ykhuang:
我在編譯cairo時出現以下錯誤, 我google了一下, 似乎找不到解法
/libfreetype.so: could not read symbols: File in wrong format
謝謝

cairo莫名奇妙又可以編譯過了, 糗!

smikid,

沒關係，有過就好 (y)

ykhuang你好：
我把交叉编译好的相关库放到开发板上后，运行gtk-demo成功出现界面（可以在屏幕上看到一个鼠标点，一个满屏的大窗口，右边还有一个滚动条，窗口中间有很多个小方框这组成的行，估计是一些字体无法显示），但在minicom上死机（就是怎么操作都无法退出程序）：

这一步死机了，按ctrl+c 也不行的，我想问问这种现象正常吗？

tiansun7k,

我想只要是死機應該就算不正常吧？我自己是沒遇過啦，雖然有很多警告訊息，但還是可以正常執行結束。

这个VT Switcher是什么东西?两个实例程序都是到这个地方死掉了,我查了一下，是virtual terminal switcher，有人说可能是虚拟终端的管理出了问题，比如说虚拟终端分配的内存释放出问题，虚拟终端的管理 这部分是由谁负责的？跟我的硬件有关系吗？能具体到哪部分代码吗？比如directfb的代码，还是gtk+的？

tiansun7k,
這方面我就沒經驗了，不過我會覺得是DirectFB的問題。也許可以從debug message去看是在哪個元件裡面，然後重新configure看有沒有機會把該元件disable。

死机的问题解决了，是因为我编译的inputerdriver的时候加了太多的没用的输入设备，由于我是在目标板上运行，硬件资源有限，而每加一个输入设备系统都要多一个进程，肯定会死机的。
当我继续运行测试程序的时候，经过测试，在运行arm-dfbg，和arm-info和在网上找的一个划线的小程序时可以完全正确运行，并且可以正常退出，而且没有任何报错和警告信息（除了： (!) Direct/Modules: Could not open module directory`/usr/local/dfb/lib/directfb-1.1-0/gfxdrivers’!
–> No such file or directory）因为编译的时候没有使用gfxdrivers,当然找不到gfxdrivers了！！

但是在运行gtk-demo的时候报了一个大家可能经常遇到的错误，不知道楼主能给指点一下，大该意思是我的fontconfig没有编译对？还是我的pango有问题？

tiansun7k,
要不要檢查fontconfig相關的library有沒有正確安裝到開發板上？再來是開發板上的字型相關檔案是不是有正確設定？我想都可以執行到這一步了，編譯過程應該是沒有問題才是…

谢谢ykhuang。
现在我有个新的问题，我自己作了个键盘，驱动也已经加载进内核了，确定可以用，我现在想通过按下键盘的上下左右键来获得我界面上的焦点，听人说好像要修改Directfb的源码，把我的驱动加进去，具体的该怎么修改，在哪个部分（哪文件夹下的哪个文件），請指教了.
比如上，下，左，右，确定，这五个键来控制我简单界面上的按钮，比如有1，2，两个按钮，通过按动键盘上左右两个键使焦点在界面上1和2两个按钮上切换，按确定键就可以调用对应那个按钮的回掉函数，进入下个界面之类的功能
有人曾经说过：需要修改波特率，这个波特率具体是哪部分的波特率，更directfb有关吗？可不可以具体一下？

我这几天把自定义的键盘的驱动通读了一遍，编了个应用程序，能够在终端上捕获键值了，可是在读directfb-1.1.1/inputdrivers/keyboard.c这个文件时，发现他的结构并不是标准的字符设备驱动
我现在想向ykhuang你确定一下，一般情况下，要想获得键值需要先open这个设备，让然后在read就可以了，但是在keyboard.c这个文件里没有main主函数，只有这几个函数：
keyboard_get_symbol （），keyboard_get_identifier（），keyboard_read_value（），keyboard_set_lights （），keyboardEventThread（），driver_get_available（），driver_get_info（）， driver_open_device（），driver_get_keymap_entry（），driver_close_device（）
在这几个函数里，只有在driver_open_device（）函数里的调用direct_thread_create（）–>keyboardEventThread( ) 里有一个：
readlen = read (data->vt->fd, buf, 64)
整个.c文件里只有这个地方用到了read系统调用，
我想问问，底层的硬件键值是不是从这里传递过来的？
directfb是通过什么得到这个键值的，他的键盘事件的触发是基于什么的？
还有人说可以将自定义的键盘输入转换为tty设备的输入，并使dfb直接用linux的tty设备作为输入，哪位高人知道这种方法，可不可以拿上来分享一下？

我最近也在弄这个, 准备在2440上跑，目前编译完成了，当目前字符显示不出来，好像还有些慢.

Hi,

我的GTK+DirectFB也已经编通，正在进行一个简单的按键驱动的集成工作，或许可以多多沟通合作，我的邮件sword_lzr@hotmail.com

我看了keypad的驱动，似乎需要在两个地方做改动：
1.修改 fd = open( “/dev/tty0″, O_RDWR | O_NOCTTY );
为我们自己的键盘/dev/button

2.修改 键值映射表，我的键值是1,2,3…9

你现在进展如何，欢迎email与我联系交流

我把GTK+和DirectFB交叉編輯完成後放入隨身碟內並插入開發板上,照著網路上的說明做好組態檔pango.modules和gdk_pixbuf.loaders , 然後執行gtk-demo或是我自己做的helloworld時會出現” Bus error ” 就沒動作了, 請問有人可以給個建議嗎?

因為整個GTK+和DirectFB的檔案是掛在隨身碟上 , 我是懷疑系統沒有動作 , 但是我不清楚如何測試 , 像我這樣從外部掛載的做法是否要先執行某些程式來初始化??
