We are trying to rebuild our Channel Access to TCL/TK interface.
We have spent over a week trying to do this, with no success.  We
really need to be able to rebuild this, as we feel the current
HP-UX channel access library may solve some longstanding CA problems.

We currently run a version of "et_wish" which was built long ago, 
and which uses R3.12.0 channel access libraries.  It was built
with TCL 7.6/4.2.  We have not been able to built a working
version of this program using R3.13.0.beta11 libraries.

While trying to figure out how to build "et_wish", we found another
TCL interface called "tclCa", which seemed to be a replacement for
"et_wish".  We have also worked with this, but cannot build a 
working executable with it either.

Many of the problems seem to stem from the packages requiring
BLT and tcl-dp.  There seem to be version problems.  We have
tried getting the newest versions from the distribution sites,
we have tried using some old verisons we found on our disks, and
we have tried removing the need for these packages.  We cannot
get a make to complete with the packages in, and we get an
executable which immediately exits if we remove them.  We feel
we may still have version problems.

If anyone has any recent experience building workable TCL/TK 
interfaces to CA, we would like to hear about how  you did it.  We
would also like to learn which TCL/CA package we should be using.
Right now we have given up, but we have to rebuild this interface.

All help will be greatly appreciated.
