There's ALWAYS a way out! You just have to understand your objectives, and what's really going on :-)

This concerns me. SHAREABLE images should not be installed with privilege. It doesn't do anything useful, but can cause image activation problems (like yours). See:

$ HELP INSTALL ADD/PRIV - in particular the bit that says:

o The /PRIVILEGED qualifier applies only to executable images.

Just to make sure we're prefectly clear on this, if you RUN the image you can give it privileges, if you LINK against an image, you CANNOT give that image privileges, and should not INSTALL the image with /PRIVILEGE.

Try removing the privileges from ALL shareable images you link against and try again. This should not break anything. Ask anyone who objects to explain exactly what /PRIVILEGE is buying them other than problems. As I said in my first response:

Standard reminder... there is NO SUCH THING as a "privileged shareable image".


(OK, there's ONE potential use for a shareable image installed with privilege, that's when it also contains a transfer address - kind of a hybrid executable image and shareable image - it is possible, but rarely done in practice, and not recommended. In that case if you INSTALL the image with privilege, you'll get the privileges if you RUN the image, but not if it's activated as a shareable image. IF you have one of these beasts, it's a simple matter of splitting up the main program part and shareable routines part, then linking them separately. As far as I know, this, and fanatical adherance to upwards compatibility, are the only reasons the /PRIVILEGE qualifier hasn't been blocked for shareable images in INSTALL)
