Hi there,

I'm quoting generously for the benefit of the mailinglist readers.

Oops, sorry, my fault.  I meant the tagdemo directory.

Yes, I will try to do so.  In this mail, I want to focus on the f77demo
issue only (it's somewhat easier :)
For the tagdemo issue, another mail will follow.

You sent me f77demo/config.log.  And this is the important part:

What happens?  I think the we need to also take over the
  -zallextract -lompstubs -zdefaultextract
so that those missing symbols are taken into account.  :-/
(This is part of autoconf macro AC_F77_LIBRARY_LDFLAGS)

To verify this: can you please try executing the following commands:

echo 'int main () { return 0; }' > a.c
# the next line should fail:
cc -o a -g a.c -lf77compat -R/opt/SUNWspro/lib/v8plus:/opt/SUNWspro/lib 
-L/opt/SUNWspro/lib/v8plus -L/opt/SUNWspro/prod/lib/v8plus -L/opt/SUNWspro/lib 
-L/opt/SUNWspro/prod/lib -L/usr/ccs/lib -L/lib -L/usr/lib -lompstubs -lfui 
-lfai -lfai2 -lfsumai -lfprodai -lfminlai -lfmaxlai -lfminvai -lfmaxvai -lfsu 
-lsunmath -lm
# but this line should succeed:
cc -o a -g a.c -lf77compat -R/opt/SUNWspro/lib/v8plus:/opt/SUNWspro/lib 
-L/opt/SUNWspro/lib/v8plus -L/opt/SUNWspro/prod/lib/v8plus -L/opt/SUNWspro/lib 
-L/opt/SUNWspro/prod/lib -L/usr/ccs/lib -L/lib -L/usr/lib -zallextract 
-lompstubs -zdefaultextract -lfui -lfai -lfai2 -lfsumai -lfprodai -lfminlai
