Hello,
When I load an EPICS example application to the vxWorks5.5.1
running on a MPC8572 CPU board, "Undefined symbol" is reported as
follows,
ld <bin/vxWorks-mpc8572/example.munch Undefined symbol:

contains undefined symbol(s) and may be unusable.
Checking the vxWorks
image, it indeed does not include these symbols. And use "grep -r" to check the
gnu library on the vxWorks host, the library files libcplus.a and
libgnucplus.a under Tornado2.2/target/lib/ppc/PPC403/gnu, PPC405/gnu,
PPC440/gnu, PPC603/gnu, PPC604/gnu and PPC860/gnu do provide these symbols,
but the libcplus.a and libgnucplus.a under Tornado2.2/target/lib/ppc/PPC85XX/gnu
directory do not provide, which seems to cause the above
error.
Do you have encountered such a problem before?
Thanks,
Lin Wang
