-----------------------------------------------------------
IMPORTANT
 - the notes below relate to the legacy build
 system from reSIProcate <= 1.7.x
 - now, with reSIProcate 1.8.x and beyond,
 please see:
 http://www.resiprocate.org/AutotoolsBuild
 and
 http://www.resiprocate.org/Configuration_Options
-----------------------------------------------------------
Notes for the legacy build system:
The legacy reSIProcate build system is derived from
the VOCAL build system (http://www.vovida.org). 
Adding New Files to a module
----------------------------
Example: Adding a new file Foo.cxx to the stack
1) Edit resip/stack/Makefile
2) Add Foo.cxx to the SRC list
Example: Adding a new file Bar.cxx to rutil
1) Edit rutil/Makefile
2) Add Bar.cxx to the SRC list
Notes: 
- All files noted in SRC list will be added to the target library
- Adding a new header file does not need to be noted in the Makefile
- To add something to the compile line add to CXXFLAGS. 
e.g. CXXFLAGS += -DMYSPECIALDEFINE
- To add something to the link line add to LDFLAGS and/or LDLIBS
e.g. LDFLAGS += -L/usr/local/myspeciallibdir
e.g. LDLIBS += -lmyspeciallib
Creating an application based on the stack: 
Option 1: (Using the resip build system)
For example applications using the resip build system look at resip/stack/test or at repro.
###########################################################################################
# Create a Makefile in the directory with the units with the following template
# This should be the path to the build directory of resip (in the sip subdirectory)
BUILD = ../../build 
# Includes macros
include $(BUILD)/Makefile.pre
# Add any options that need to be passed to the C++ compiler here
#CXXFLAGS += -DMYSPECIALDEFINE
# Add any options that need to be passed to the C compiler here
#CFLAGS += -DMYOTHERDEFINE
# Add any options that need to be passed to the linker here
#LDFLAGS += -L/usr/local/mydir
# Add any libraries that need to be passed to the linker here
#LDLIBS += -lmylib
# All of these packages are prerequisites for resiprocate
PACKAGES += RESIP RUTIL OPENSSL ARES PTHREAD
# Add an entry to TESTPROGRAMS for each target that has a main in it
# On linux this will generate an executable in bin.debug.Linux.i686/main
TESTPROGRAMS += main.cxx
# Add each of the C++ or C files that other than the main
# Each main target (from TESTPROGRAMS) will be linked with all of the files in SRC
SRC = 		TestSupport.cxx
# Includes macros
include $(BUILD)/Makefile.post

Option 2: (Using a third party build system)
Prerequisites: 
- Install ares library from contrib/ares 
 - cd contrib/ares
 - ./configure
 - make
 - make install
Pass the following flags to C++ compiler: 
Assumptions: 
- have pthreads
- have openssl installed
- have ares installed
- resiprocate library is built and installed
# Linux Example
CXXFLAGS += -Wall -fPIC -Wno-deprecated -march=i686 \
 -D_REENTRANT -DUSE_SSL -DNEW_MSG_HEADER_SCANNER -DUSE_IPV6 -DUSE_ARES \
 -I/usr/kerberos/include -I$(RESIP_DIR)/lib.debug.Linux.i686 
LDFLAGS += -L$(RESIP_DIR)/lib.debug.Linux.i686 
LDLIBS += -lresip -lrutil -lssl -lcrypto -lares -lpthread
