Hello,
I am trying to cross compile Directfb for a hico7760
http://www.emtrion.com/hico7760st_linux_en.php
I have crosscompiled other libraries before, but none dealing with
graphics. My goal is to replace the Qt embedded library shipped with the
device. I don't need window management, only screen manipulation,
graphics primitives, font, and png support.
I have already built libfreetype libz and libpng12
I have configured directfb with:
cd $BSP/pkgs/src/DirectFB
./configure --prefix=$BSP/pkgs/bin/DirectFB --enable-zlib --host=sh4
CC=sh4-linux-gcc
I get the output:
Build options:
Version 1.4.3
Linux powered no
Install prefix /pkgs/bin/DirectFB
Config files in /pkgs/bin/DirectFB/etc
Build shared libs no
Build static libs yes
Module directory ${exec_prefix}/lib/directfb-1.4-0
CPPFLAGS -D_REENTRANT
CFLAGS -O3 -ffast-math -pipe -D_GNU_SOURCE
-Werror-implicit-function-declaration
LDFLAGS
LIBS -lpthread
DYNLIB
THREADFLAGS -D_REENTRANT
THREADLIBS
Misc options:
Multi Application Core no
Fusion Kernel Device N/A
Fusion message size 1024
Voodoo (network support) no
Debug supported yes
Debug enabled no
Trace support no
MMX support no
SSE support no
Network support yes
Include all strings yes
Software Rendering yes
Smooth SW Scaling no
16bit Dithering none
zlib compression yes -lz
sysfs support no
Building Tests no
Building Tools yes
Building System Modules:
Linux FBDev support no
Generic /dev/mem support yes
X11 support no
OSX support no
SDL support no
VNC support no
Building Window Manager Modules:
Default yes
UniQuE no
Building Image Provider Modules:
GIF yes
JPEG no
PNG yes
-I/usr/include/libpng12 -lpng12
Building Video Provider Modules:
GIF yes
Video4Linux no (v2: no)
Building Font Modules:
FreeType2 yes -I/usr/include/freetype2
-lfreetype
Default font yes
JPEG support is missing - many applications won't work correctly!
Everything looks good so far to me...
I then run make and get undefined references to functions in libz and
the math libs, called from libpng in the tools/ dir.
I change tools/Makefile to read
LIBPNG_LIBS = -lpng12 -lz -lm
make then completes and I run make install.
on the target device. running dfbinfo produces:
~ # dfbinfo

(*) DirectFB/Core: Single Application Core. (2010-08-05 01:24)
(!) DirectFB/core/system: No system found!
(#) DirectFBError [DirectFBCreate() failed]: No (suitable)
implementation found!
Have I missed something? does DirectFB not support this device? I don't
know what else I'm supposed to do.
Thanks in advance.
