No, I didn't need to download any file.
I did
whereis libfam.la
and I got
libfam.la:
but I looked for the file in the disks of my distribution, and I found it.
Before you answered me, I was a bit lost because I had tried to find the file using
find -name libfam.*
and I had found a couple of files fitting this pattern, but none of them was the one I needed. Then I thought I had installed the library and I didn't understand what was going on.
But, as I tell you, I instaled the package (the one I found in my distro containing that file), and all is ok now
Thank you, again. I feel now less
Best regards
