# This file gets included into the main Makefile, in the top directory.
# Ideally, we want something like this:
#
# /lib/libproc.so.w ELF soname ('w' is a digit, starting from 1)
# /lib/procps-x.y.z.so file itself (x.y.z is the procps version)
# /lib/libproc.so for linking, UNSUPPORTED
# /usr/lib/libproc.a for linking, UNSUPPORTED
# proc/libproc.so.w as above, if testing with LD_LIBRARY_PATH
# proc/whatever if testing with LD_PRELOAD
# proc/libproc.a for static build
#
# Without a stable ABI, there's no point in having any of that.
# Without a stable API, there's no point in having the *.a file.
#
# A new ELF soname is required for every big ABI change. To conserve
# numbers for future use, the ELF soname can be set equal to the
# file name until some future date when a stable ABI is declared.
