Dear all:
; I am trying to use tslib for my touch-panel in Directfb, but I got the
following error:
*********************************************
Couldnt load module pthres
(!) DirectFB/tslib: Error configuring `/dev/input/event1`!
**********************************************
It is not just the pthres module, but also all of the modules
after the raw module (e.g. variance, dejitter, linear, etc.)
However, my ts test programs and tinyX server don't have
any problem loading the tslib library.
I traced the code and found that when tslib is called by Directfb,
it has problem doing "dlopen" on the pthres module. Interestingly,
tslib doesn't have this problem when it was called by TinyX or my
test program.
Just wondering if anyone has run into the same issue.
Here is my Directfb config:
./configure --prefix=/opt/dfb --enable-zlib --enable-fbdev --with-tests
--with-gfxdrivers=none --with-inputdrivers=tslib,keyboard --enable-debug
My tslib is configured to read linux raw input (/dev/input/event1). And
this is my tslib config:
---------------------------------
module_raw input
module pthres pmin=1
module variance delta=30
module dejitter delta=100
module linear
---------------------------------
tslib is working for other programs; so I assume it is ok.
Greatly appreciate it if someone can help me with this.
Thank you,
Alan

Best regards,
