Dear All,

I am working through 'Linux Assembly "Hello World" Tutorial, CS 200'
by Bjorn Chambless.  But I am unable to compile the program given in
that.  Kindly help me. 

For your convenience I have included the assembly program at the end
of this mail.

average.s is the relevant assembly program file.

$ as -a --gstabs -o average.o average.s

$ ld -m elf_i386 -static /usr/lib/crt1.o /usr/lib/crti.o -lc average.o
                              /usr/lib/crtn.o
