[libvirt] Regarding the installtion of libvirt on ubuntu

I have installed libvirt-bin on ubuntu using the following command:sudo apt-get install libvirt-bin I checked the virsh version. It says 4.6.0.Now i want to recompile libvirt with esx, xen and hyperv driver.Therefore i went to /usr/src/libvirt-4.6.0 and trying to run the following command:./configure --prefix=/usr --localstatedir=/var --sysconfdir=/etc --with-esx=yes --with-xen=yes but i am getting the following error:error: you must install the gnutls>=3.2.0 pkg-config module to compile libvirt. So i have installed gnutls-binand it is already the latest version. Why libvirt is not able to identify gnutls... what is the solution for this???  Thanks & Regards,Mousumi Paul---Senior R & D Engineer Vigyanlabs Innovations Private Limited
