In my original poster I asked if it was possible to compile a binary built
on Tru64 V5.1+ to run on Tru64 pre-V5 O/S without various unresolved
symbols.
Okay, I have received several answers from tru64-unix-managers list (see
below). The common response is that we can not guarantee backwards binary
compatibility (see Joe Mario <mario_at_zk3.dec.com> reply). Here are a few
suggestions:
1) -D__V40_OBJ_COMPAT to CFLAGS
2) compile on pre-V5.0 workstation
3) downgrade to Tru64 4.0F with Fibre Channel support
(host bus adapter f/w is fine). See KGPSA release notes:
http://www6.compaq.com/products/storageworks/adapters/64bitpcifibre.html
4) upgrade everything to Tru64 V5.1+ (part of our migration plan)
In our case, option 1) worked for us but it may not work for all case. Be
warned!
