Use of ldexp() requires -lm on some platforms; use gnulib to determine this for our makefile. Also, optimize virRandomInt() for the case of a power-of-two limit (actually rather common, given that Daniel has a pending patch to replace virRandomBits(10) with code that will default to virRandomInt(1024) on default SELinux settings). * .gnulib: Update to latest, for ldexp. * bootstrap.conf (gnulib_modules): Import ldexp. * src/Makefile.am (libvirt_util_la_CFLAGS): Link with -lm when needed. * src/util/virrandom.c (virRandomInt): Optimize powers of 2.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
