checking for dm_task_run in -ldevmapper... no configure: error: You must install device-mapper-devel/libdevmapper
= 1.0.0 to compile libvirt
/dev/mapper exists on the system.
You need the *-devel version of those packages (they provide include files in particular). I think it is something like libdevmapper-devel. Note that the "dev" stands for "device", while the "devel" stands for "development files".
You may get few other errors like this one, don't forget to install *-devel versions of the packages that they complain about.
Frederic.
On Fedora development packages end in -devel. On Debian/Ubuntu development packages end in -dev. The necessary package for Ubuntu is called: libdevmapper-dev Matthias
