From 7ceaa0c7449e841d7ca7db889c3041dc3fedbb3b Mon Sep 17 00:00:00 2001 From: Jon Ludlam Date: Mon, 10 Oct 2011 16:37:07 +0100 Subject: tools/ocaml: Rename the ocaml libraries ocamlfind does not support namespaces, so to avoid name clashes the module names have become longer. Additionally, the xenstore and xenbus subdirs, which contain several modules each, have been packed into toplevel Xenstore and Xenbus modules. xb becomes xenbus, xc becomes xenctrl, xl becomes xenlight, xs becomes xenstore, eventchn becomes xeneventchn and mmap becomes xenmmap. [ Patch modified from that submitted, to update the .hgignore, and to cope with intervening changes to mmap_stubs.c -iwj ] Signed-off-by: Jon Ludlam Acked-by: Ian Campbell Signed-off-by: Ian Jackson Committed-by: Ian Jackson --- .hgignore | 4 +- tools/ocaml/libs/eventchn/META.in | 4 +- tools/ocaml/libs/eventchn/Makefile | 18 +- tools/ocaml/libs/eventchn/eventchn.ml | 30 -
