Host type?

[Vaclav Barta]

Hi,

I've been trying to compile one of my programs on a new Linux
installation (Czech RedHat 7.1), but configure failed:
...
checking whether c++ accepts -g... yes
checking for ranlib... ranlib
checking host system type... configure: error: can not guess host type;
you must specify one

On my home computer (SuSE Linux 6.4), the package configures OK...
What exactly is the host type and how does autoconf guess it?

        Bye
