I tried to
make && make install package, but I get an error:
libX11.so.6 not found
Where can I get this library?
You need to install the libX11 package:
$ rpm -qf /usr/lib/libX11.so.6 libX11-1.3.1-3.fc13.i686
$ yum -y install libX11
One more thing though: if you don't know how to find and install a library package, care to share why you are trying to compile a piece of software that is officially packaged for Fedora 13 in the most recent version?
$ yum info gpicview Available Packages Name : gpicview Arch : x86_64 Version : 0.2.1 Release : 3.fc13 Size : 93 k Repo : fedora Summary : Simple and fast Image Viewer for X URL : http://lxde.sourceforge.net/gpicview/ License : GPLv2+ Description : Gpicview is an simple and image viewer with a simple and intuitive interface. : It's extremely lightweight and fast with low memory usage.

I bet a more appropriate response would be to install libX11-devel...
