Installation of Eclipse CDT IDE in Fedora 9.

Ref [1] Debugging Linux Application using Eclipse+GDB

1. Download latest Eclipse CDT IDE.

[q.yang@localhost Download]$ ll
-rwxr--r-- 1 q.yang q.yang 91574228 2010-07-23 14:25 eclipse-cpp-helios-linux-gtk.tar.gz

3. Installation Eclipse CDT (IDE 3.6.0 CDT 7.0.0)
[q.yang@localhost ~]$ mkdir EclipseCDT
[q.yang@localhost EclipseCDT]$ tar zxf ~/Download/eclipse-cpp-helios-linux-gtk.tar.gz

4. Start first Eclipse Project
[q.yang@localhost eclipse]$./eclipse

Then set work space storage folder

Add /home/q.yang/EclipseCDT/eclipse/ into $PATH so that command line '$eclipse' will open eclipse IDE.

5. Create Make file based C/C++ application project
Not makefile will be generated by eclipse CDT. Good for import existing makefile based source codes and projects. Only use eclipse as a debugger mainly and trigger 'make'.

New-->C++ project
Then give the project name 'GsnProjEclipseHelloCpp'.
And uncheck 'use default location', browse to choose Root directory of source codes '/home/q.yang/lpc3250/ltib-qs/rootfs/home/user/GsnHelloCppRoot'

As shown in this screen shot.

After creating 'Makefile project', attached is the project view screen shot:

6. Set debug configuration
In C/C++ editing view, right click project, choose 'Debug As' -> 'Debug Configurations ...'

Create button to new a debug configuration, rename this new debug configuration as 'GsnProjEclipseDebugConfig'.
Then click browse to choose C/C++ application 'hellocpp', which is the binary executable program generated by makefile.

As shown in this screen shot:

Set up GDB debugger (from LTIB tool chain) and GDB command file as shown in the screen shot:

[q.yang@localhost qywkspace]$ pwd
[q.yang@localhost qywkspace]$ ll
total 16
-rw-rw-r-- 1 q.yang q.yang 145 2010-07-26 12:28 eclipseGdbCmdFile
drwxrwxr-x 4 q.yang q.yang 4096 2010-07-26 14:20 Gsn_HelloCpp_Eclipse
[q.yang@localhost qywkspace]$ cat eclipseGdbCmdFile
set remotetimeout 0
set solib-absolute-prefix /opt/freescale/usr/local/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi/arm-none-linux-gnueabi/

Set up Debugger Options -> Shared Libraries as shown in this screen shot (LTIB lib)

Set up Debugger Options -> Connection as shown in this screen shot (via Ethernet to target board phytec 3250)

7. Done. You would be able to do single step debugging now.
As shown in this screen shot:

[root@GsnCommsModule debug]# gdbserver hellocpp
Process hellocpp created; pid = 501
Listening on port 2000
Remote debugging from host
Hello world!
Hello there. First GsnCpp from Eclipse IDE.
Child exited with retcode = 0
