Name

vxworks_dxml − Using DXML on VxWorks

Description

This file describes how to compile and link an application using DXML library on VxWorks system. Examples given below assume the host system is running Digital UNIX and the target is an AXPvme system running VxWorks. For other host and/or target system, please refer to the operating system Manual and the VxWorks Reference Manual.

The archived DXML library must be installed on the host system. Only routines from BLAS, Lapack and Signal Processing are available for the VxWorks environment.

To Compile (on Host)

cc -c -I/[path-spec] -non_shared -std1 -DCPU=21064 f1.c

where

-I/[path-spec]gives access to include files in specified directories;

-DCPU=assume a Alpha 21064 chip;

f1.cfile name of the example.

This creates the object file "f1.o".

To Create a VxWorks Loadable Image (on Host)

ld -non_shared -o output.o -r f1.o end.o -ldxml -lots ./lib/lib21064osfmath.a

where

-ris used to retain relocation entries in the output file "output.o" for the VxWorks loader;

end.ois a dummy object file provided in the DXML kit to let the VxWorks loader bypass some symbols it cannot resolve;

./lib/lib21064osfmath.a
is the VxWorks version of "libm.a".

The output file "output.o" is created.

To Load the Image (on Target)

ld < output.o

After the image is successfully loaded, it is ready to run. You can verify the newly loaded image "output.o" by typing moduleShow
