PtHook.so - dlopen: Library cannot be found

QNX DEVELOPERS Realtime and Embedded

Hi,

I am using QNX 6.30 on a embedded platform (SH4). I can start Photon and run PWM + any application with USB mouse and keyboard support.
However I noticed that setting DL_DEBUG=1 I get the following error when I start PWM:

export DL_DEBUG=1

pwm &

…
dlopen(“PtHook.so”,0)
load_object: attempt load of PtHook.so
dlopen: Library cannot be found
dlopen(“wframe_updated.so”,0)
load_object: attempt load of wframe_updated.so
dlopen: Library cannot be found
…

Does any one know what PtHook.so is, I can not find it anywhere!

Thanks,
Paul

do ‘find / -name PtHook.so’ on the terminal, that searches the whole disk for it.
