Cross compiling wxDFB-2.8.11 for ARM-Linux

Without GUI, cross compilation of wxWidgets is pretty easy. However it does not provide wxImage. With DirectFB, a lot of errors produce, just like many cross compilations. What you need are zlib-1.2.5, libpng-1.2.43, libjpeg (jpegsrc.v8b) , freetype-2.3.12
and wxWidgets-2.8.11. It is important to use libpng 1.2.x, not libpng 1.4.x.

[*] If you get errors:

rename /usr/local/lib temporarily.

wxWidgets-2.8.11

A typo in src/common/strconv.cpp which produces an error:

src/common/strconv.cpp:1679:22: error: token "=" is not valid in preprocessor expressions

#if SIZEOF_WCHAR_T == 4 _T("UCS-4"), #elif SIZEOF_WCHAR_T = 2 _T("UCS-2"),

#if SIZEOF_WCHAR_T == 4 _T("UCS-4"), #elif SIZEOF_WCHAR_T == 2 _T("UCS-2"),

I need to add --disable-debug_gdb to complete disable debug when building for 2440.

Linking to wxDFB

If your IDE support backtick execution, use bin/wx-config (http://wiki.wxwidgets.org/Wx-Config) and other configuration script in bin. Newest Eclipse looks like not support this. I manually added all flags. I ran all configuration scripts and cat *.la
to find out the flags.
