[libvirt-users] Fail to install libvirt

Hi all, I am trying to install libvirt from source code(I have some version of libvirt installed before and I intend to overwrite it), my workflow is shown below, #!/bin/sh apt-get install gnutls-bin libgnutls-dev -y apt-get install libxml++2.6-2 libxml++2.6-dev -y apt-get install libdevmapper-dev -y apt-get install libpciaccess-dev -y apt-get install python-dev -y apt-get install libnl-dev -y if [ ! -f ./libvirt-1.1.1 ]; then wget http://libvirt.org/sources/libvirt-1.1.1.tar.gz fi tar -xzvf ./libvirt-1.1.1.tar.gz cd ./libvirt-1.1.1 ./configure --prefix=/usr --localstatedir=/var --sysconfdir=/etc make make install I have no trouble in configure, make, and make install. However, after make installfinishing, when I type virsh --version, I get the following error message: virsh: /usr/lib/libvirt.so.0: version `LIBVIRT_PRIVATE_1.1.1' not found (required by virsh) I wonder what's wrong with that? Please help, thanks! -- Best Regards, Frank
