[Ovirt-devel] oVirt Source Repository Refactoring

[Ben Guthro]

I'm having some issues building after the refactoring, and I was hoping 
someone might be able to point me in the right direction...

I am only interested in building the managed node pxe images, at this point.
As I understand this restructuring, this means I need the following 
repos to build:
ovirt-release
ovirt-node
ovirt-node-image

I should be able to do without the other subcomponents that I am not 
interested in, correct?

To build I execute make overriding the following environment variables:
FEDORA_URL                  Use a local yum mirror
OVIRT_CACHE_DIR         Override location to make this behave as before, 
and put it in a
                                          local dir to the build area
SUBDIRS="node node-image" Only build what I care about.
OVIRT_BRANCH               build on the "next" branch

However, it would seem that something in the automake magic is picking 
up the SUBDIRS override, because it seems to be using it incorrectly 
when it tries to make the "node" dir. (see make output below)

Am I doing something wrong here? Is this a supported operation?

I am going to run ./configure with no arguments - if you wish
to pass any to it, please specify them on the ./autogen.sh command line.
