Makefile

#
# This makefile system follows the structuring conventions
# recommended by Peter Miller in his excellent paper:
#
#       Recursive Make Considered Harmful

# We create a listing of the root directories for access into

# '$(V)' controls whether the lab makefiles print verbose commands (the
# actual shell commands run by Make), as well as the "overview" commands
# (such as '+ cc lib/readline.c').
#
# For overview commands only, the line should read 'V = @'.
# For overview and verbose commands, the line should read 'V ='.
V = @

# Set the compiler and compile-time loaded libraries
CXX           := g++
LDLIBRARYPATH :=  

# For profiling (with gprof), this line should read 'PG = -pg'
# For fast execution, this line should read 'PG ='.
PG = 

# For debugging (with gdb), this line should read 'DEBUG = -g'
# For fast execution, this line should read 'DEBUG ='
DEBUG = -g

# Set the flags for C++ to compile with (namely where to look for external
# libraries) and the linker libraries (again to look in the ext/ library)
CXXFLAGS := -g -MD $(PG) -I$(SRCDIR) -I$(OBJDIR) -std=c++1y
