|
# Description:
|
| 14 |
|
|
# ------------
|
| 15 |
|
|
# This is an easily customizable makefile template. The purpose is to
|
| 16 |
|
|
# provide an instant building environment for C/C++ programs.
|
| 17 |
|
|
#
|
| 18 |
|
|
# It searches all the C/C++ source files in the specified directories,
|
| 19 |
|
|
# makes dependencies, compiles and links to form an executable.
|
| 20 |
|
|
#
|
| 21 |
|
|
# Besides its default ability to build C/C++ programs which use only
|
| 22 |
|
|
# standard C/C++ libraries, you can customize the Makefile to build
|
| 23 |
|
|
# those using other libraries. Once done, without any changes you can
|
| 24 |
|
|
# then build programs using the same or less libraries, even if source
|
| 25 |
|
|
# files are renamed, added or removed. Therefore, it is particularly
|
| 26 |
|
|
# convenient to use it to build codes for experimental or study use.
|
| 27 |
|
|
#
|
| 28 |
|
|
# GNU make is expected to use the Makefile. Other versions of makes
|
| 29 |
|
|
# may or may not work.
|
| 30 |
|
|
#
|
| 31 |
|
|
# Usage:
|
| 32 |
|
|
# ------
|
| 33 |
|
|
# 1. Copy the Makefile to your program directory.
|
| 34 |
|
|
# 2. Customize in the "Customizable Section" only if necessary:
|
| 35 |
|
|
# * to use non-standard C/C++ libraries, set pre-processor or compiler
|
| 36 |
|
|
# options to and linker ones to
|
| 37 |
|
|
# (See Makefile.gtk+-2.0 for an example)
|
| 38 |
|
|
# * to search sources in more directories, set to
|
| 39 |
|
|
# * to specify your favorite program name, set to
|
| 40 |
|
|
# 3. Type make to start building your program.
|
| 41 |
|
|
#
|
| 42 |
|
|
# Make Target:
|
| 43 |
|
|
# ------------
|
| 44 |
|
|
# The Makefile provides the following targets to make:
|
| 45 |
|
|
# $ make compile and link
|
| 46 |
|
|
# $ make NODEP=yes compile and link without generating dependencies
|
| 47 |
|
|
# $ make objs compile only (no linking)
|
| 48 |
|
|
# $ make tags create tags for Emacs editor
|
| 49 |
|
|
# $ make ctags create ctags for VI editor
|
| 50 |
|
|
# $ make install make all and install the executable file
|
| 51 |
|
|
# $ make clean clean objects and the executable file
|
| 52 |
|
|
# $ make distclean clean objects, the executable and dependencies
|
| 53 |
|
|
# $ make help get the usage of the makefile
