automake编译工程

首先准备工程完整清晰的目录，cd到要生成makefile的主目录，下面将分布说明怎样用automake编译工程，所有的1,2,3,4,5,6都是在主目录操作的。

1 输入：“autoscan” 生成configure.scan
2 输入：“mv configure.scan configure.ac”
3 输入：“vi configure.ac”

添加：AM_INIT_AUTOMAKE(hello,1.0)

AC_CONFIG_FILES([Makefile])

并添加
AC_PROG_RANLIB
//有sub目录时记得都写出来：例如只有一个文件夹Source,则:Makefile source/Makefile 上面不用更改只添加这两处。
//有源码的目录都要写下来，在有源码的地方都要写Makefile.am。
//如果有子目录，必须是在主目录的子目录里面写Makefile.am，不能是主目录的上层目录写Makefile.am否则会失败。

例如：
AC_PREREQ([2.63])
AC_INIT([FULL-PACKAGE-NAME], [VERSION], [BUG-REPORT-ADDRESS])
AC_CONFIG_SRCDIR([Zlog.h])
AC_CONFIG_HEADERS([config.h])
AM_INIT_AUTOMAKE(zlog,1.0)
AC_CONFIG_FILES([Makefile
source/Makefile])
（当生成.a文件时需要加上：AC_PROG_RANLIB）
AC_PROG_CXX
AC_PROG_CC
AC_PROG_RANLIB

4 输入：“aclocal“ 生成 aclocl.m4
5 输入：”autoconf“ 生成 configure
6 输入：vim Makefile.am

在主目录中：SUBDIRS = source(如果没有子目录则在主目录编写子目录内容)

SUBDIRS = src/handle_module/transcode src/handle_module/cover_standard src/heartbeat

在子目录中如source中或其他，举几个例子

//生成publicparty.a(这个是个公共库，不在主目录子目录的框架中，是个独立的makefile.am，和其他makefile.am无关)。

AM_CPPFLAGS = -I ./publicpartyAUTOMAKE_OPTIONS = foreign
CXXFLAGS += -g -Wall -lpthreadlib_LIBRARIES = libpublicparty.alibpublicparty_a_SOURCES = lvsm_datatime.cpp \lvsm_conf.cpp \lvsm_file.cpp \lvsm_log.cpp \lvsm_socket.cpp \lvsm_socketpair.cpp \lvsm_tcp.cpp \lvsm_udp.cpp \lvsm_thread.cpp \lvsm_public_extend.cppinclude_HEADERS = lvsm_info.h \lvsm_datatime.h \lvsm_conf.h \lvsm_file.h \lvsm_log.h \lvsm_socket.h \lvsm_socketpair.h \lvsm_tcp.h \lvsm_udp.h \lvsm_thread.h \lvsm_public_extend.hall-am:@echo -e "\\e[32m"      @echo "build lvsm:libpublicparty.a success."      @echo -e "\\e[0m"

//生成libtranscode.a

AM_CPPFLAGS = -I ../../../../publicparty -I ./transcode
LD_ADD = ../../../../publicparty/libpublicparty.a AUTOMAKE_OPTIONS = foreign
CXXFLAGS += -g -Wall -lpthreadlib_LIBRARIES = libtranscode.alibtranscode_a_SOURCES = lvsm_transcode.cppinclude_HEADERS = lvsm_transcode.h
libtranscode_a_LIBADD = ${LD_ADD}all-am:@echo -e "\\e[32m"      @echo "build lvsm:libtranscode.a success."      @echo -e "\\e[0m"

//生成libcoverstandard.a

AM_CPPFLAGS = -I ../../../../publicparty -I ./cover_standard
LD_ADD = ../../../../publicparty/libpublicparty.aAUTOMAKE_OPTIONS = foreign
CXXFLAGS += -g -Wall -lpthreadlib_LIBRARIES = libcoverstandard.alibcoverstandard_a_SOURCES = lvsm_cover_standard.cppinclude_HEADERS = lvsm_cover_standard.h
libcoverstandard_a_LIBADD = ${LD_ADD}all-am:@echo -e "\\e[32m"      @echo "build lvsm:libcoverstandard.a success."      @echo -e "\\e[0m"

//生成可执行程序lvsmbeatheart

AM_CPPFLAGS = -I ../../../publicparty -I ../handle_module/cover_standard -I ../handle_module/transcode -I ./heartbeat
LD_ADD = ../../../publicparty/libpublicparty.a \../handle_module/cover_standard/libcoverstandard.a \../handle_module/transcode/libtranscode.a \-lrt AUTOMAKE_OPTIONS = foreign
CXXFLAGS += -g -Wall -lpthread
bin_PROGRAMS = lvsmbeatheartlvsmbeatheart_SOURCES = lvsm_heartbeat.cpp \main.cpp
include_HEADERS = lvsm_heartbeat.h
lvsmbeatheart_LDADD = ${LD_ADD}all-am:@echo -e "\\e[32m"      @echo "build lvsm:lvsmbeatheart success."      @echo -e "\\e[0m"

7 输入："autoheader" 生成 config.h.in
8 输入："automake --add-missing" 生成 Makefile.in
9:输入："./configure --prefix="要生成的可执行程序绝对目录名称""
有时会产生：
Makefile.am: required file `./NEWS' not found
Makefile.am: required file `./README' not found
Makefile.am: required file `./AUTHORS' not found
Makefile.am: required file `./ChangeLog' not found

则输入“touch NEWS README AUTHORS ChangeLog”

//总结
1）修改Makefile.am文件
2) 修改configure.ac文件，运行autoconf生成configure文件（它是由aclocal.m4与configure.ac生成的， aclocal.m4是由configure.ac运行aclocal生成的）
3）运行autoheader生成config.h.in。
4）运行automake --add-missing生成Makefile.in,Makefile.in是由automake在Makefile.am基础上生成的。
5) 运行./configure生成Makefile， config.h， Makefile是由configure 在Makefile.in上生成的, config.h是由config.h.in生成的

autoreconf -fi:当Makefile.am改变时然后./configure
