#
# Generic Makefile for C/C++ Program
#
# Description:
# The makefile searches in <SRCDIRS> directories for the source files
# with extensions specified in <SOURCE_EXT>, then compiles the sources
# and finally produces the <PROGRAM>, the executable file, by linking
# the objectives.

# Usage:
#   $ make           compile and link the program.
#   $ make objs      compile only (no linking. Rarely used).
#   $ make clean     clean the objectives and dependencies.
#   $ make cleanall  clean the objectives, dependencies and executable.
#   $ make rebuild   rebuild the program. The same as make clean && make all.
#==============================================================================

## Customizing Section: adjust the following if necessary.
##=============================================================================

# The executable file name.
# It must be specified.
# PROGRAM   := a.out    # the executable name
PROGRAM   :=

# The directories in which source files reside.
# At least one path should be specified.
# SRCDIRS   := .        # current directory
SRCDIRS   :=

# The source file types (headers excluded).
# At least one type should be specified.
# The valid suffixes are among of .c, .C, .cc, .cpp, .CPP, .c++, .cp, or .cxx.
# SRCEXTS   := .c      # C program
# SRCEXTS   := .cpp    # C++ program
# SRCEXTS   := .c .cpp # C/C++ program
SRCEXTS   :=

# The flags used by the cpp (man cpp for more).
# CPPFLAGS  := -Wall -Werror # show all warnings and take them as errors
CPPFLAGS  :=

# The compiling flags used only for C.
# If it is a C++ program, no need to set these flags.
# If it is a C and C++ merging program, set these flags for the C parts.
CFLAGS    :=
CFLAGS    +=

# The compiling flags used only for C++.
# If it is a C program, no need to set these flags.
# If it is a C and C++ merging program, set these flags for the C++ parts.
CXXFLAGS  :=
CXXFLAGS  +=

# The library and the link options ( C and C++ common).
LDFLAGS   :=
LDFLAGS   +=

## Implict Section: change the following only when necessary.
##=============================================================================
# The C program compiler. Uncomment it to specify yours explicitly.
#CC      = gcc

# The C++ program compiler. Uncomment it to specify yours explicitly.
#CXX     = g++

# Uncomment the 2 lines to compile C programs as C++ ones.
#CC      = $(CXX)
#CFLAGS  = $(CXXFLAGS)

# The command used to delete file.
#RM        = rm -f

## Stable Section: usually no need to be changed. But you can add more.
##=============================================================================
