This discussion regarding threading on Digital Unix has prompted me to
pass along information regarding a problem I had compiling OpenLDAP 1.2.0
under Digital Unix 4.0D
Basically, I managed to get the product to compile using Digital's native
compiler, but cannot get it compiled using gcc.
To do this though, I had to add in an additional subset, which Digital Unix
gurus (Dr. Tom Blinn) inform me will no longer be supported in the future
releases of Digital Unix/Tru64 Unix.
Below is Tom's email response to me. Could I suggest that the OpenLDAP
developers work with Tom to remove the dependency on this future obsolete

That is VERY interesting. I don't think that you really need that subset to
get threads support, but it could be that the OpenLDAP setup script that is
driving the build believes there is a component in that subset that it needs
to do the build using "cc". It would be interesting to examine the script and
compare the files it's looking for to the inventory list for the subset.
If you look in /usr/.smdb. you will find a file called OSFCDAPGMR425.inv ; in
that file is a list of all the files, links, and directories in the subset.
It is a somewhat odd format, tab delimited, and some of the fields might not
be obvious; the format is documented in the "Product Kits" guidebook in the
If you compare the list of files and links delivered in the subset to those in
the OpenLDAP build script, I bet you will get some hits. In other words, what
I think you are finding is that the OpenLDAP build depends on one or more of
the CDA libraries in that subset.
I would have to double check the retirement list, but I believe we are getting
rid of that subset in a future release of Tru64 UNIX. If there are libraries
in it that are needed by "freeware" products, we need to understand why that
is. So I will probably have to go find someone to investigate this, unless
you are willing to check it out and report back your results. (I understand
it's not something you should have to do, but if you're going to depend on the
software, we should try not to break it in a future release.)
