[xsde-users] Cross-compilation libxsde for PPC under vxWorks

[Jaws]

   The hardware FP unit is not enabled. It is enabled only  the
   soft-float.
   The xml schema use xs:decimal and xs:double type.
   I rebuild the runtime library with the -g option and without any
   optimization.
   This is the stack trace of the error:

   XML_GetParsingStatus (a53e640, 2d877a8)
   Another strange thing is: if I try to build the application code
   without the optimization my linkcheck returns an error like this:
     _ZnwjPv undefined
   If I build the application code to test the xml part with at least -O1
   the undefined symbol disappear.
   Any suggestion is welcome.
   Thanks

Hi,

Jaws [1]<jaws75 at tiscali.it> writes:



   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


Could it be that your target does not support floating point operations?
There are a few built-in XML Schema types that are mapped to types that
require this support. These types are: xs:float, xs:double, xs:decimal,
xs:time, xs:dateTime, and xs:duration. Can you check if your schema uses
any of these types?

Also, the stack trace you provided is not very helpful because the
program is compiled with optimization. Can you recompile everything
with -g instead of -O2 and show the resulting stack trace?

Boris
