When i start the io-graphics driver the Sloginfo gives error "Failed to open hook dll devg-rotate90.so, unable to 
library file".
though i have put the dll in /usr/lib and /lib/dll path also set LD_LIBRARY_PATH to these locations.The .so also in the 
specified path in the image.
Also when i use pidin command with "mem" option the hook dll devg-rotate90.so is not shown in the list.
Please check my build file which i have attached in the post.
