When building a shareable image on OpenVMS Alpha and OpenVMS I64, it's possible to encounter the error:
%ILINK-F-CMDTOOLONG, command line too long in options file filename
With the symbol vector.
The OpenVMS error messages and recovery helpfully tells you:
CMDTOOLONG, command line too long in options file ' file-name '
Facility: LINK, Linker Utility
Explanation: An options file line is too long.
User Action: Shorten the line and relink.
But what to do with the symbol vector, if that's too large? If you have too many entry points to declare?
