   i resolved the issue related the compilation/link adding the option
   -fno-rtti -O2.
   Now I have a problem on the target. I have created an example that
   read an xml file make the parsing and generate some messages.
   Everithing works on Linux , but When I try to run on the target
   (PPC860 with vxWorks) from the command on the shell, I have received
   the following error:
   fp unavailable
   Machine Status Register: 0x00009032
   Data Access Register: 0xeeeeeeee
   Condition Register: 0x42004024
   Fp Control and Status Register: 0xeeeeeeee

   shell restarted.
   Do you have any idea or suggestion?

   I am using gnu gcc 3.4.5 for ppc with the following option:
        -U_BIG_ENDIAN -fno-common -mno-sdata -pipe -Wno-invalid-offsetof
   -mcpu=860 -fno-branch-count-reg -ansi
   building the runtime library and the application the following error are
   reported by the linker:

     _ZnwjPv undefined
     _ZTVN10__cxxabiv117__class_type_infoE undefined
     _ZTVN10__cxxabiv120__si_class_type_infoE undefined
     _ZTVN10__cxxabiv121__vmi_class_type_infoE undefined

Looks like the runtime type information support is not available on this
target. Can you try to recompile the XSD/e runtime and your application
with the -fno-rtti and see if this helps?

You can do this by adding this option to the CXXFLAGS variable in your
config.make and then rebuilding the XSD/e runtime (make clean && make).
You will also need to use this option while compiling the generated code
and your application code.

Let us know how it goes.
