[Info-vax] C_TEST_ROUTINES.C link problem

Hi,

I'm starting to understand how OpenVMS I/O takes place and how to debug this.

I have two OpenVMS Alpha virtual machines. They talk to each other through the debugger as described in the manuals (boot -fl 0,8000 dka0,ewa0)

There is one routine in the system$examples called  C_TEST_ROUTINES.C
that helps to understand what the kernel does.

Now the link step fails :
%LINK-W-NUDFSYMS, 1 undefined symbol:
%LINK-I-UDFSYM,         XDT$FREGSAV
%LINK-W-USEUNDEF, undefined symbol XDT$FREGSAV referenced

I have no idea how to get rid off this failure.

Any ideas?

Eberhard
