Hi all,

Im a complete beginner who needs to run slffea 1.5 on ubuntu for my masters thesis, I've been trying to install it but with little success...everytime I try to run make i get back the following error?

L/usr/local/lib -lglut -lGLU -lGL -lm -L/usr/X11/lib -L/usr/X11R6/lib -lX11 -lXext -lXmu -lXt -lXi -lSM -lICE
/usr/bin/ld: cannot find -lXi
collect2: ld returned 1 exit status
make[1]: *** [bmpost] Error 1
make[1]: Leaving directory `/usr/local/src/slffea-1.5/beam/beam_gr'
make: *** [everything] Error 2

I cant seem to find the missing element, does anyone know where I should look or what I need to do to make this work?
