I've noticed for some time that whenever I type `make' in the Cyrus
source tree, it always recompiles something.  A repeated make should
evenually stop compiling but this one never does.  The worst offenders
are the various perl Makefiles which rebuild Makefile from Makefile.PL
every time, instead of only doing it when it's out of date.  This
I'm not a Perl guy, so I don't know if this is necessary or not.

The problem is that Makefile.PL is not really a Makefile.  It's run
by perl to create the Makefile.  I suppose that that should be done
by the configure step, not by the compile step.

Sounds reasonable to me.


causes the perl modules to be recompiled.  As well, imap/Makefile
recreates xversion.h each time, resulting in more recompiles.
We recreate xversion.h (and imapd as a result) so we get an accurate CVS timestamp in imapd for version reporting.

I'm not a CVS guy, but there must be a better way to accomplish this
without causing a recompile.

If there is, I'd love for somebody to tell me. We look at the CVS timestamp of ALL of the source files and then put that into xversion.h


This behavior is annoying because I build the Cyrus software on a
development server but then install it on other servers where there
is no compiler and the source tree is mounted read-only.  This breaks
`make install', which should only install things, not recompile them.
Can this be fixed, or am I condemned to hack Makefiles myself?
A 'make install' shouldn't compile anything if all of the generated files already exist. I would consider this a bug and would gladly accept a patch which fixes this behavior.

Is there a release coming soon, perhaps to fix the core dump that
we heard about?  If so, I'll use that distribution to work on a patch.

There will be a release as soon as I track down and fix the bug that causes mupdate to randomly spin in 2.3.
