Re: Shared Ada Library to be Used in a Non-Ada Context

["Ludovic Brenta" <ludovic.brenta@insalien.org>]

Here is a complete, working Makefile.  gnatlink links
libservices.so.0.0 against libgnat properly.  When running main, you
need to set LD_LIBRARY_PATH so that the dynamic linker finds
libservices.so.0.

libservices.so.0.0 contains the actual shared library.
libservices.so.0 is needed when running main, because of the soname.
libservices.so is needed when linking main, because of -lservices.

This Makefile should work on any unix-like OS.
