Subject: undefined symbol when loading EPICS IOC on vxWorks

Hello All,
When I load EPICS IOC on vxWorks, the following error informatioin appears,
 
-> </home/wanglin/vx6_6App/iocBoot/iocexmaple/st.cmd
## Example vxWorks startup file
## The following is needed if your board support package doesn't at boot time
## automatically cd to the directory containing its startup script
#cd "/home/wanglin/vx6_6App/iocBoot/iocexmaple"
#< cdCommands
#< ../nfsCommands
#cd topbin
cd "/home/wanglin/vx6_6App"
value = 0 = 0x0
ld < bin/vxWorks-ppc604_long/exmaple.munch
Warning: module 0x1fffb390 holds reference to undefined symbol __gxx_personality_v0.
Warning: module 0x1fffb390 holds reference to undefined symbol _Unwind_Resume.
Warning: module 0x1fffb390 holds reference to undefined symbol __cxa_pure_virtual.
Warning: module 0x1fffb390 holds reference to undefined symbol _ZTIv.
ld(): error loading file (errno = 0xe0005).
value = 0 = 0x0
The EPICS version is 3.14.11, the vxWork version is 6.6 with a patch cum.vxw6-4.1.2-ppc.2010aug12.zip, the host is RHEL4.8, the target is mvme5100. And when I use "grep   _Unwind_Resume   vxWorks_6.6_1   vxWorks_6.6_1.sym" command, nothing matches. I have added the required and optional components when building vxworks image following this link http://www.aps.anl.gov/epics/base/vxWorks6.php , does it means that I need to add other components? But which components? How can I find them?
 
Thanks,
Lin Wang
