linux makefile (English)

#############################################################################
# Generic Makefile for C/C++ Program
# Usage:
# ------
# 1. Copy the Makefile to your program directory.
# 2. Customize in the "Customizable Section" only if necessary:
#    * to use non-standard C/C++ libraries, set pre-processor or compiler
#      options to <MY_CFLAGS> and linker ones to <MY_LIBS>
#      (See Makefile.gtk+-2.0 for an example)
#    * to search sources in more directories, set to <SRCDIRS>
#    * to specify your favorite program name, set to <PROGRAM>
# 3. Type make to start building your program.
#
# Make Target:
# ------------
# The Makefile provides the following targets to make:
#   $ make           compile and link
#   $ make NODEP=yes compile and link without generating dependencies
#   $ make objs      compile only (no linking)
#   $ make tags      create tags for Emacs editor
#   $ make ctags     create ctags for VI editor
#   $ make clean     clean objects and the executable file
#   $ make distclean clean objects, the executable and dependencies
#   $ make help      get the usage of the makefile
#
#===========================================================================

## Customizable Section: adapt those variables to suit your program.
##==========================================================================

# The pre-processor and compiler options.
# MY_CFLAGS = -ggdb3 -pipe -O2 -Wall -Wextra -fopenmp -march=native -mfpmath=sse -DLINUX -m64 -std=c++0x
MY_CFLAGS = -g -DLINUX -Itest1/include -Itest2/include -Itest1/include/test1 -Itest2/include/test2

# The linker options.
# MY_LIBS   = -lGLEW -lglut -lGLU -lGL -lX11 -lXmu -lXi -lm -L/usr/X11R6/lib -lgomp -lOpenThreads -lpthread

# The options used in linking as well as in any direct use of ld.
LDFLAGS   =

# The directories in which source files reside.
# If not specified, only the current directory will be serached.
SRCDIRS   =

# The executable file name.
# If not specified, current directory name or `a.out' will be used.

## Implicit Section: change the following only when necessary.
##==========================================================================

# The source file types (headers excluded).
# .c indicates C source files, and others C++ ones.
SRCEXTS = .c .C .cc .cpp .CPP .c++ .cxx .cp

# The header file types.
HDREXTS = .h .H .hh .hpp .HPP .h++ .hxx .hp

# Users can override those variables from the command line.

# The command used to delete file.
