To use the Makefile you must first set the following environment variables 
to match your system and compiler requirements:

CXX: path and name of compiler
	ex: export CXX=/opt/SUNWspro/bin/CC  (C++ compiler on Solaris)
CCFLAGS: compiler options
	ex: export CCFLAGS="-g -O"  
		-g enable debug
		-O optimize code
LDFLAGS: linker/loader options
	ex: export LDFLAGS="-g"
LIBS: extra libraries to link in
	ex: export LIBS="-lpthread"
