Can anyone explain me the library naming convention in AIX. The library
libicuio.so is named in linux as: libicuio.so, libicuio.so.34 and
libicuio.so.34.0.
While in AIX it is named as: libicuio.a, libicuio34.a and
libicuio34.0.a. Does it mean that we have to name libraries in AIX as:
libicu<MAJOR_VERSION>.<MINOR_VERSION>.a

You can use Unix/Linux convention and have libfoo.2.3.so with
libfoo.2.so and libfoo.so (symbolically) pointing to the actual
file.

Or you can build a module foo.2.3.so and archive it into libfoo.a.
When it's time to update (i.e. provide a new version, mark the old
module as load-only (ldedit command), put it into the archive so that
existing programs that use that version will still run, and add a
new module foo.2.4.so for linking new programs. Repeat as necessary.
The convenient thing about archives on AIX is that you can have a single
file to house all versions of your modules, not worry about filesystem
entries and symlinks (which can create problems) and hides details
that the average shouldn't/doesn't care about.
