system tap unable to refer a structure definition

[Gadre Nayan <gadrenayan@xxxxxxxxx>]

Hi,

I am trying a script to read some headers which are passed from one module to another.

c = @cast($frags[0]->f_addr, "volioship_hdr_t", 
           "/root/ngadre/unixvm-cvs/src/common/kernel/vxvm/ioship_cvm.h")

printf("Arguments: [Frag[0]->size: %d, Frag[0]->f_addr: %u, Sender: %d, Receiver: %d]\n",  $frags[0]->f_size, $frags[0]->f_a    ddr, c->iosh_sender, c->iosh_receiver)

The header file is locally available on the machine.

Error Msg:

semantic error: type definition 'volioship_hdr_t' not found in '/root/ngadre/unixvm-cvs/src/common/kernel/vxvm/ioship_cvm.h': operator '@cast' at :46:6

        source:         c = @cast($frags[0]->f_addr, "volioship_hdr_t", "/root/ngadre/unixvm-cvs/src/common/kernel/vxvm/ioship_cvm.h")

How do I make system tap refer to this structure.

Thanks
