Problem with building a non-shareable QKDRIVER

[Hurworth, Erik]

Hello all,

If you are in testing mode, it is easier to use the disk image of Quick then
you don't have to keep running INSTALL to install and deinstall the QKDRIVER
every
time you make a change to your 3GL routines.

Use BuildExternal to build your QKDRIVER.EXE object library in the normal
way.
Set up a symbol to run the uninstalled disk version of Quick:-

$QUICK == "PH_LOCATION:QUICKA710F.EXE;"

Note the ; character at the end of the symbol definition.

Now, when you run the command QUICK, it will run the disk version and will
then
be able to find the QKDRIVER.EXE in the same directory.

I hope this is what you are after,


Regards

Non-shareable won't work.
An image is either shareable or executable, and you can only run one
executable
at a time (eg QUICKA710F.EXE) - the images it links to must be shareable.
Shareable images by definition don't (mustn't) have a main() program, just
some
functions of global scope, declared as universal by a symbol_vector in the
linker options file.

I've never used buildexternal myself: I just link my own shareable images,
and
I've never had any trouble.

In the past I've used ph_location:dalock.aobj (which I don't recommend).
I've run into conflict between VAXC & DECC. (I think DALOCK used to be
VAXC).

I used to use the following in my linker options files:

 sys$share:vaxcrtl/share
 psect_attr=userbreak,noshr     ! from DALOCK/VAXC

but no longer need it, apparently (710G3, Alpha VMS 7.1).
We're mostly Pascal here, rather than C, but we do have one DECC module I
can
think of which we've successfully put into a QKDRIVER image & called from
Quick.

If you need more specific help, you'll have to more clearly describe your
problems.

Regards,
Chris Sharman
