TCPWARE 5.7-2 installation error on ALPHA OPENVMS7.3-2

[Desmond Or]

I tried to upgrade one of our ALPHA-1000 box TCPWARE 5.6-2 to 5.7-2 under OpenVMS 7.3-2, the following error comes up

Installing TCP-OpenVMS

%LINK-W-NUDFSYMS, 4 undefined symbols:
%LINK-I-UDFSYM, SDA$EXTEND_PRINT_CC
%LINK-I-UDFSYM, SDA$EXTEND_SKIP_LINES
%LINK-I-UDFSYM, SDA$EXTEND_TRYMEM64
%LINK-I-UDFSYM, SDA$EXTEND_VECTOR_TABLE_ADDR
%LINK-W-USEUNDEF, undefined symbol SDA$EXTEND_TRYMEM64 referenced
in psect $LINK$ offset %X00000050
in module TCPWARE$SDA file ALPHA $DRA0:[SYS0.SYSUPD.TCPWARE057]DRIVERS_VS
.OLB;1
...

I also upgraded 3 of other ALPHA DS-20 (OpenVMS 7.3-2) boxes but without problem.

Does anyone know why the symbols are undefined?

TCPware 5.7 contains an SDA extension image that is useful for Process Software technical support to request information about the state of TCPware should the system crash (and write a dump). That is what the TCPWARE$SDA image is.

This image is linked against the VMS library sys$library:vms$volatile_private_interfaces

I would guess that the system that had the problem has an incomplete version of this VMS library. You might want to do a LIBRARY/LIST of the library file on the various systems and compare the contents.

The link below provides more information about writing SDA extension images.
