	Run command "sudo ldconfig -v"
	Logout and Login will reflect the environment variables.(system reboot)



3.	Do I need to export library path (<APP SDK>/lib/x86, /x86_64) ?
Ans:    Environment variables are set globally by the new installer scripts, so you do not need to set any library 
        path(<APP SDK>/lib/x86, /x86_64).

4.	Do I need to export AMDAPPSDKROOT?
Ans:    No 

5.	Do I need to export LD_LIBRARY_PATH?
Ans:    No 

6.	Do the environment variables reflect to all users?
Ans:    Yes, the new installer scripts set the environment variables globally and hence the environment variables reflect
        to   all users.

11.	What should I change if I don't want to install under /opt/AMDAPP.
Ans:    "default-install_lnx.pl" file should be updated with the new location of your choice

12.	How to change/update The Environment variables if not working.
Ans:	a) Open  /etc/profile and then check the AMDAPPSDKROOT and LD_LIBRARY_PATH settings

13.     How Install AMD APP manually.
Ans:    To Install manually, please follow below steps.
	i)   untar the AMD-APP-SDK-v2.5-RC2-lnx32.tgz for 32-bit OS, use the command #tar -xvzf <package name> . This will 
             create a folder with name AMD-APP-SDK-v2.5-RC2-lnx32. You can find all the required files inside the folder
      
	     untar the AMD-APP-SDK-v2.5-RC2-lnx64.tgz for 64-bit OS, use the command #tar -xvzf <package name> . This will 
             create a folder with name AMD-APP-SDK-v2.5-RC2-lnx64. You can find all the required files inside the folder
	ii)  untar the icd-registration.tgz using the command #tar -xvzf icd-registration.tgz . This will create folder with 
             name etc/OpenCL in the current directory
	iii) Copy the to above OpenCL folder to /etc/
	iv)  Open the terminal, go the the SDK folder(AMD-APP-SDK-v2.5-RC2-lnx64/32), then run the below commands
             # export AMDAPPSDKROOT=`pwd`
             # export LD_LIBRARY_PATH=<path>/AMD-APP-SDK-v2.5-RC2-lnx32/lib/x86   for 32bit OS
             # export LD_LIBRARY_PATH=<path>/AMD-APP-SDK-v2.5-RC2-lnx64/lib/x86_64:<path>/AMD-APP-SDK-v2.5-RC2-lnx64/lib
               /x86             for 64bit OS
