From fb9ad93a3d422c1e83c998f44c4782f7bf1d1a66 Mon Sep 17 00:00:00 2001 From: Alan Conway Date: Fri, 1 Dec 2006 05:11:45 +0000 Subject: 2006-12-01 Jim Meyering This delta imposes two major changes on the C++ hierarchy: - adds autoconf, automake, libtool support - makes the hierarchy flatter and renames a few files (e.g., Queue.h, Queue.cpp) that appeared twice, once under client/ and again under broker/. In the process, I've changed many #include directives, mostly to remove a qpid/ or qpid/framing/ prefix from the file name argument. Although most changes were to .cpp and .h files under qpid/cpp/, there were also several to template files under qpid/gentools, and even one to CppGenerator.java. Nearly all files are moved to a new position in the hierarchy. The new hierarchy looks like this: src # this is the new home of qpidd.cpp tests # all tests are here. See Makefile.am. gen # As before, all generated files go here. lib # This is just a container for the 3 lib dirs: lib/client lib/broker lib/common lib/common/framing lib/common/sys lib/common/sys/posix lib/common/sys/apr build-aux m4 git-svn-id: https://svn.apache.org/repos/asf/incubator/qpid/trunk/qpid@481159 13f79535-47bb-0310-9956-ffa450edef68 --- cpp/src/qpid/sys/Module.h | 161 ---------------------------------------------- 1 file changed, 161 deletions(-) delete mode 100644 cpp/src/qpid/sys/Module.h (limited to 'cpp/src/qpid/sys/Module.h') diff --git a/cpp/src/qpid/sys/Module.h b/cpp/src/qpid/sys/Module.h deleted file mode 100644 index db791666e0..0000000000 --- a/cpp/src/qpid/sys/Module.h +++ /dev/null @@ -1,161 +0,0 @@ -#ifndef _sys_Module_h -#define _sys_Module_h - -/* - * - * Licensed to the Apache Software Foundation (ASF) under one - * or more contributor license agreements.
