Dear friends,
Thanks, as always, to all our cheerful friends at NCAR for their assistance.
I think I followed Rick's instructions here correctly but (my particular
problem- there might be others) is that even after his remedy, the file :
/usr/local/ncarg/lib/ncarg/database/pwritdata
was missing from its desired location.
It seems that the make in
> $NCARG/ncarg2d/src/db/pwritxnt
did not copy the file to the desired location. A simple copy did and now my
pwrit* calls seem to be working satisfactorily.
However, some examples are missing their annotation which suggests to me that
probably there is a similar problem with the fontcap make.
I cannot see the answer immediately. Is someone able to help and perhaps see
the wider implications of what has happened here?
Yours sincerely,
Bill
