Hi Ed,
seems like you've managed to get quite far already.
Apparently it crashes somewhere in libdirect (not libdirectfb) but
without more specific location info it is going to be hard to tell the
problem. I am not aware of any known issues there.
It would be helpful to eg. use gdb or gdbserver, or do an strace, or put
additional prints in libdirectfb_tslib to narrow down.

I am trying to get DirectFB running on the mini2440.
I am using openembedded to create my image.
In the directfb_1.4.2.bb file I have entered the following in the extra
OE configure section.
EXTRA_OECONF = "\
--enable-debug \
--enable-trace \
--enable-extra-warnings \
--with-inputdrivers=tslib \
--enable-fbdev \
--enable-freetype=yes \
--enable-zlib \
--with-gfxdrivers=none \
--disable-sdl \
--disable-vnc \
--disable-x11 \
TSLIB_CFLAGS=\"-I${INSTALL_PATH}/include\" \
TSLIB_LIBS=\"-L${INSTALL_PATH}/lib\" \
"
On the mini2440 I have exported the following variables.
export TSLIB_TSDEVICE=/dev/input/touchscreen0
export TSLIB_CALIBFILE=/etc/pointercal
export TSLIB_PLUGINDIR=/usr/lib/ts
export TSLIB_CONFFILE=/etc/ts.conf
I created a directfbrc file in /etc with the following lines.
memcpy=libc
debug
debugmem
debugshm
trace
I ran ts_calibrate to configure display before running dfbinfo.
Verified that there is a symbolic link from event1 to touchscreen0.
r...@mini2440:/dev/input# ls -l
crw-r----- 1 root root 13, 64 Mar 7 23:19 event0
crw-r----- 1 root root 13, 65 Mar 7 23:19 event1
crw-r----- 1 root root 13, 63 Mar 7 23:19 mice
crw-r----- 1 root root 13, 32 Mar 7 23:19 mouse0
lrwxrwxrwx 1 root root 6 Mar 7 23:19 touchscreen0 ->
event1
But when I run dfbinfo the program crashes right after probing tslib
input driver.
Below is the output.
ANY IDEAS ??????
