Eclipse Luno does not load after linking with Opencl Code Builder

I am using Centos 7 to use Opencl Code Builder. I have already downloaded and installed Intel Media Server Studio for Centos 7 OS. To start programming with Opencl, I use Eclipse Luno (Eclipse for Parallel Application Developers version) and the Eclipse IDE is loaded properly. To link with Code Builder, I followed the discussion here. The instructions are

To enable the OpenCL™ API Offline Compiler plug-in for Eclipse* IDE, do the following:

1. Copy the plug-in *.jar file from $(INTELOCLSDKROOT)\bin\eclipse-plug-in to $(ECLIPSEROOT)\dropins.
2. On Linux* OS add $(INTELOCLSDKROOT)\bin to LD_LIBRARY_PATH.
3. Run Eclipse IDE.
4. Select Window> Preferences.
5. Switch to the Intel OpenCL dialog and set OpenCL binary directory$(INTELOCLSDKROOT)\bin\. I have already finished 1 and 2. But when I run Eclipse IDE, I have error and IDE stop loading in halfway. The error is "Cannot get machine list. Could not load required libraries. Please make sure to set the correct path under the Code Builder for Opencl preference page". What is wrong with that error? Thanks
