it's about like this:
write a file with the functions inside
write a header file, define the functions as public
compile as PIC (position independent code)
link as shared library

   gcc -c -fPIC -I/usr/include/ myfile.c
( creates myfile.o )
  gcc  -omyfile.so -shared myfile.o -L/usr/lib/ -lanydependancy
( creates myfile.so )

autoconf, automake etc. are old
If you wanted to, I'd suggest to use a more recent build tool (e.g.
scons, cmake, git, .. )
