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
