Download openstack-nova-2014.2.1-1.el7.src.rpm
Then as root:-

    # rpm -iv openstack-nova-2014.2.1-1.el7.src.rpm
    # cd; cd rpmbuild/SPEC;
    #  yum install python-sphinx python-oslo-sphinx python-d2to1 graphviz
    # rpmbuild -bb  openstack-nova.spec

I've just updated CentOS 7 and repeat build . Don't use "yum" installing src.rpm.

Why do we need Openstack-nova-objectstore ? Also now do i install Openstack-nova-objectstore as mentioned earlier or just the openstack-nova-2014.2.1-1.el7.src.rpm ? And what effect will these make to openstack ?

Per openstack-nova-objectstore is required on Controller.

# rpm -iv  openstack-nova-2014.2.1-1.el7.src.rpm
# cd ; cd rpmbuild/SPEC
# rpmbuild -bb openstack-nova.spec
