How to compile the vxWorks?

[shen guobao <shengb@ssrc.ac.cn>]

Hello, everybody,
I use the MVME2302(MPC603,200MHz,32M RAM) as my target,host is
Sun/Solaris2.7.
When I finished installing the PowerPC BSP, I cant compile the
vxWorks as default, but it report the following error:
"
ldppc -X -N -e _sysInit -Ttext 00100000  \
    -o vxWorks dataSegPad.o vxWorks.tmp ctdt.o
vxWorks.tmp: In function `dcStartOutput':
vxWorks.tmp(.text+0x67cc): undefined reference to `m_freem'
gnumake: *** [vxWorks] Error 1
$ 
"

I dont know which patch would repair it, how can I do?

Thanks and Regards,
guobao shen
