Porting GTK+ on DirectFB

移植GTK的過程真的很繁雜,要先編幾十個library.
過程請直接參考強者同學的網誌: GTK+ on DirectFB on Creator PXA270
遇到error時通常把message原封不動的拿到google搜尋都可以找到解決的辦法, 以下提供新手參考.

編譯glib-2.9.6時
Error: cannot run test program while cross compiling See 'config.log' for more details
Solution:
echo ac_cv_type_long_long=yes>arm-linux.cache
echo glib_cv_stack_grows=no>>arm-linux.cache
echo glib_cv_uscore=no>>arm-linux.cache
echo ac_cv_func_posix_getpwuid_r=yes>>arm-linux.cache
configure參數多加 --cache-file=arm-linux.cache

編譯atk-1.10.3時
Error: glib-genmarshal: error while loading shared libraries: /opt/DYNAMIC/lib/libglib-2.0.so.0: ELF file OS ABI invalid
Solution: 先將環境變數LD_LIBRARY改為空白, make後再復原

執行GTK程式時
Error: (!) Direct/Modules: Could not open module directory `/usr/myproj/usr/myproj/lib/directfb-1.0-0/systems'! --> No such file or directory
Solution: 可以看到路徑重複兩次, 不知道是為什麼. 自行建立link即可

Error: (!) Direct/Modules: Could not open module directory `/usr/myproj/usr/myproj/lib/directfb-1.0-0/gfxdrivers'! --> No such file or directory
Solution: 在編譯directfb的時候gfxdrivers已經選擇none, 應該是不需要額外的driver才對, make一個空的資料夾可以過

Error: GdkPixbuf-WARNING **: Cannot open pixbuf loader module file '/usr/myproj/etc/gtk-2.0/gdk-pixbuf.loaders': No such file or directory
Solution:
在target執行/usr/myproj/bin/gdk-pixbuf-query-loaders > /usr/myproj/etc/gtk-2.0/gdk-pixbuf.loaders
參考: problem with realplayer

Error: (!) DirectFB/FBDev: Panning display failed! --> Invalid argument
Solution: (目前未解)

Error: No fonts found; this probably means that the fontconfig library is not correctly configured. You may need to edit the fonts.conf configuration file.
Solution: 修改etc/fonts/fonts.conf, 加入字型檔的路徑
然後把字型複製到預定的路徑裡面, 可以是windows的ttf

Error:
Gdk-DirectFB-WARNING **: gdk_window_set_keep_above() not implemented.
Gdk-DirectFB-WARNING **: gdk_window_set_keep_below() not implemented.
視窗畫面上的toolbar都顯示不出來, 不支是否跟這有關係
Solution: Warning而已不用理他, 強者同學說沒有window manager的觀念所以視窗不會有toolbar
