362.0. "Unresolved external reference" by MEOC02::PARKERSALLY (Sally Parker) Thu Jan 30 1997 23:16
A customer is using KAP (F90) on an 8 cpu AS8400 (V3.2F DU, ~july SPL
KAP) and experiencing library problems as indicated below. I've gone through the
notes and provided him with insight from notes 302 and 312.
Comments and advise welcomed...
QUERY: when I try to create a parallel version it fails due to
unresolved external references. The routines are:
mppfork_, mppjoin_, mppvsy_, mppfkd_.
I have checked and routines with those names do not exist
in any library in /usr/lib so I suspect an incorrect
installation or some mismatch between the program (kap) and
the library. There are routines kmp_fork, kmp_join and
kmp_vsync in the library kmp_osf.
I shared with him info from notes 302 (undefineds with -lkmp_osf,
mppfkd, mpp...) and 312 (libphpf), and he says that the routines are not
in the libkmp_osf library, quote...
"These should be but aren't - I looked in the file with ar
-t and they are simply missing - somebody should get back to
software development and kick somebody - it appears that the
routine names have been changed in the compiler and not in
the library (or vice versa)"
If someone has experienced a similar problem I'd appreciate some
feedback on how to rectify it - Thanks.

| You didn't say what command the customer was using
to build the program.
Please post the output you get on the screen when
the customer uses the following command to parallelize
his/her code:
kf90 -fkapargs='-conc' -v

thats no use at all
here's the results of doing that - its not something I'm doing wrong,
its an
error in the contents of the library!!!!!
(the -lkmp_osf was a US suggestion, it didn't make any difference
either)

wrt the BOM stuff, I have had some slight improvements using single cpu
KAP but
I really want to see the results of using multi-cpu and if DEC can't
deliver
that then they can't compete!

| 362.3 | kf90 will do the compile and link in one step | HPCGRP::DEGREGORY | Karen 223-5801 | Fri Feb 21 1997 09:11 | 17 |
| I don't understand why you are separating out the compilation and linker steps.
(by the way I have been corresponding by email to Dirk van der Knijff on this
same problem).
Do the following:
kf90 -r8 -i4 -O4 -fkapargs='-conc' testcopy.f copyit.f my_pe.f libtimer.a \
-o testx
The "unresolved external reference" message you were getting was because
when you did the link step separately you were not specifying that you wanted
parallel (no -conc switch) therefore you were not linking to the KAP
parallel library or to the DECthreads library.
