Subject: lvm2: Patch for bootstrapping without redhat-cluster (libcman-dev, libdlm-dev)

Date: Mon, 10 Feb 2014 18:20:05 -0800

[Message part 1 (text/plain, inline)]

Source: lvm2
Version: 2.02.104-1
Severity: wishlist
Tags: patch

As the subject says: this patch adds a bootstrapping build for lvm2
without libcman-dev and libdlm-dev available.  This resolves the
Build-Depends cycle: lvm2 Build-Depends on libcman-dev and libdlm-dev;
redhat-cluster Build-Depends on libvirt-dev; and libvirt Build-Depends
on lvm2.

libvirt build-depends on lvm2.  However it can't use it at all during
build.  So there is no reason at all to do that.

I was just choosing one example cycle; but there are numerous others.  In 
fact, libvirt (and therefore redhat-cluster) has a very heavy dependency chain 
which I'm sure involves the lvm2 client libraries all over the place.  Just to 
give another couple examples:

libvirt also Build-Depends on libdevmapper-dev; and since libvirt0 gets a 
binary dependency on libdevmapper1.02.1, I'd say there's probably a good 
reason for that one.
libvirt Build-Depends on libparted0-dev, and parted Build-Depends on 
libdevmapper-dev.

So getting rid of the lvm2 build-dep wouldn't yield much so closing this
report. We can patch convigure.ac to not detect but hardcode paths to
the binaries if this is really required. Please reopen in this case.

Closed the wrong bug. Sorry.

I looked into this patch now. Due to changes in lvm2, it unfortunately
is no longer applicable. There is no --with-clvm anymore. I'm therefore
removing the patch tag.

The libcman-dev part seems to have gone away entirely. redhat-cluster
was removed from unstable.

However libdlm-dev is still there, but does it still pose a cycle? I
looked but couldn't easily identify one. Can this bug be closed now?
