UPDATE: I still have problems for step i), executable file produced, and can be run normally. 
Only problem now is debug step. I need some advices!


a) Start Eclipse and set the workspace to the SDK install folder/projects
   
b) Create a new C or C++ Makefile Project 
   New>File>C++ Project; then choose ("Makefile project" in the "Project types" selection window)
   In the "Toolchain" selection window select "Linux GCC",set a name and click Finish. Let's say the project name is CUDA_test
   
c) Add a new Source File with the extension eg. "CUDA_test.cu" and click Finish
   File>New>Source File

d) Add a new File called "Makefile" (File>New>File) and click ok

e) Edit the Makefile 
   Copy these lines to the makefile:

#################################################

# Build script for project

#################################################

EXECUTABLE := CUDA_test

# cu files

CUFILES := CUDA_test.cu

# c/c++

CCFILES :=

CUDA_INSTALL_PATH := /usr/local/cuda

PROJECT_PATH := .

NV_ROOT_PATH := /home/username/NVIDIA_GPU_Computing_SDK/C

ifeq ($(emu), 1)

LIB := -lcufftemu

else

LIB := -lcufft

endif

# Basic directory setup for SDK

# (override directories only if they are not already defined)

#SRCDIR ?= $(PROJECT_PATH)/Source

#ROOTDIR ?= $(PROJECT_PATH)

#ROOTBINDIR ?= $(PROJECT_PATH)/bin

#BINDIR ?= $(ROOTBINDIR)/linux

#ROOTOBJDIR ?= $(ROOTBINDIR)/obj

#LIBDIR := $(NV_ROOT_PATH)/lib

#COMMONDIR := $(NV_ROOT_PATH)/common

include ../../common/common.mk

#######################################################

f) now edit the CUDA_test.cu file

g) now you have to change the Project properties.
	Right click the project and select properties.
	g.1) Select C/C++ Build options.
                Deselect the option "Use default build command". 
                Then, on the Build command input field enter:

For release mode let the field with "make" unchanged.
For debug mode enter "make dbg=1" (Use customarily this option)
For debug emulation mode enter "make dbg=1 emu=1"
(this enables the user to acces GPU functions when debugging
Notice that that the used compiler for GPU functions is not nvcc but gcc)
For emulation mode enter "make emu=1".

	g.2) Still in the C/C++ Build options, 
                Switch to tab "Behaviour" 
                Empty the textboxes next to Build (Incremental build)  and Clean [delete "all" and "clean"]
                (located at the  bottom of :Workbench Build Type" area)
	        Select the line "Discovery options" under the menu C/C++ Build
	        set the Discovery profile to "GCC per project scanner info profile"
        g.3) At  C/C++ General
                Select the line "Paths and symbols" under the menu and 
	        switch to the tab "Library Paths". Click on Add and enter "$LD_LIBRARY_PATH". 
		Select the box "Add to all configurations"
	        At last click ok to close this tab, and again to close the "Paths and symbols window"
         g.4) Ctrl + b to Build Project 
       
h) Now create a debug profile for this project (assuming the executable could be produced).
	h.1) Right click the Project option and select "Debug As..">"Open Debug Dialog...".
	Double left-click on C/C++ Local Application to add a new debug configuration
        
        h.2) Select the new configuration and then  in  the line "C/C++  Application:" 
        click "Browse..."  and select the executable from your filesystem.
        [it should be here "/home/username/NVIDIA_GPU_Computing_SDK/C/bin/linux/release/"]
	
	h.3) Now switch to the tab common and select in the box "Display in favorites menu" the 
	checkbox for Debug. Press Apply and close the window.
	
i) Press F11 to start the program or select the start configuration from the "bug" button 
	in the shortcut menu. 
        Then you have the following options:
 
        RUN dialog give the different opportunities
        F8 from break point to break point (or end)
        F6 execute stepwise 
        F5 step into function
