利用Linux下自动生成makefile的工具： automake， autoconf 生成makefile的一般过程
1. 创建工程目录和各个目录下的makefile.am。工程的名字一般和最终生成应用程序的名字相同。wzb@embedded ~]$ mkdir workspace [wzb@embedded ~]$ cd workspace/ [wzb@embedded workspace]$ ls [wzb@embedded workspace]$ mkdir testAutoMake [wzb@embedded workspace]$ ls testAutoMake [wzb@embedded workspace]$ cd testAutoMake/ [wzb@embedded testAutoMake]$ ls [wzb@embedded testAutoMake]$ mkdir src [wzb@embedded testAutoMake]$ ls src [wzb@embedded testAutoMake]$ pwd /home/wzb/workspace/testAutoMake [wzb@embedded testAutoMake]$ ls src [wzb@embedded testAutoMake]$ vi makefile.am [wzb@embedded testAutoMake]$ cd src [wzb@embedded src]$ ls [wzb@embedded src]$ vi main.c [wzb@embedded src]$ ls main.c [wzb@embedded src]$ vi main.c [wzb@embedded src]$ clear [wzb@embedded src]$ ls main.c [wzb@embedded src]$ vi makefile.am [wzb@embedded src]$ clear [wzb@embedded src]$ ls main.c makefile.am [wzb@embedded src]$ cd .. [wzb@embedded testAutoMake]$ ls makefile.am src [wzb@embedded testAutoMake]$ pwd /home/wzb/workspace/testAutoMake [wzb@embedded testAutoMake]$ ls -R .: makefile.am src ./src: main.c makefile.am [wzb@embedded testAutoMake]$
[wzb@embedded testAutoMake]$ pwd
/home/wzb/workspace/testAutoMake
[wzb@embedded testAutoMake]$ ls
makefile.am src
[wzb@embedded testAutoMake]$ cat makefile.am
SUBDIRS=src
[wzb@embedded testAutoMake]$ vi makefile.am
[wzb@embedded testAutoMake]$ cd src
[wzb@embedded src]$ ls
main.c makefile.am
[wzb@embedded src]$ cat main.c
#include <stdio.h>
#include <stdarg.h>
int accumulate(int nr, ...);
int main(int argc, char *argv[]) {
int n = 5;
int result = accumulate(5, 5, 4, 3, 2, 1);
printf("%d,\n", result);
printf("test.......makefile ........ok\n");
return 0;
}
int accumulate(int nr, ...) {
int i = 0;
int result = 0;
va_list arg ;
va_start(arg, nr);
for(i=0; i<nr; i++) {
result += va_arg(arg, int);
}
va_end(arg);
return result;
}
[wzb@embedded src]$ pwd
/home/wzb/workspace/testAutoMake/src
[wzb@embedded src]$ cat makefile.am
bin_PROGRAMS=testAutoMake
testAutoMake_SOURCES=main.c
[wzb@embedded src]$2.通过命令autoscan，创建autoconf的模板，生成configure.in 文件。
首先在工程目录中，通过执行autoscan命令，生成autoconf的模板文件configure.scan 文件，将其改名为configure.in。
需要两处修改：
(1). 将configure.in文件中的语句：AC_INIT(FULL-PACKAGE-NAME, VERSION, BUG-REPORT-ADDRESS)中的
FULL-PACKAGE-NAME: 替换为你指派的开发工程包的名字：如本工程的：test_AutoMake;
VERSION: 开发的版本号，一般格式：主版本号.从版本号。 如 0.1；
BUG-REPORT-ADDRESS: 提交bug的邮件地址： 如wzb12008@sina.com。
(2). 还要添加一句： AM_INIT_AUTOMAKE(testAutoMake, 0.1) 即AM_INIT_AUTOMAKE(package_name, version);
用来初始化automake。
[wzb@embedded testAutoMake]$ pwd /home/wzb/workspace/testAutoMake [wzb@embedded testAutoMake]$ ls makefile.am src [wzb@embedded testAutoMake]$ autoscan autom4te: configure.ac: no such file or directory autoscan: /usr/bin/autom4te failed with exit status: 1 [wzb@embedded testAutoMake]$ ls autoscan.log configure.scan makefile.am src [wzb@embedded testAutoMake]$ vi configure.scan [wzb@embedded testAutoMake]$ vi configure.scan [wzb@embedded testAutoMake]$ mv configure.scan configure.in [wzb@embedded testAutoMake]$ ls autoscan.log configure.in makefile.am src [wzb@embedded testAutoMake]$ cat configure.in # -*- Autoconf -*- # Process this file with autoconf to produce a configure script. AC_PREREQ(2.59) AC_INIT(FULL-PACKAGE-NAME, VERSION, BUG-REPORT-ADDRESS) AC_CONFIG_SRCDIR([src/main.c]) AC_CONFIG_HEADER([config.h]) # Checks for programs. AC_PROG_CC # Checks for libraries. # Checks for header files. AC_HEADER_STDC # Checks for typedefs, structures, and compiler characteristics. # Checks for library functions. AC_CONFIG_FILES([makefile src/makefile]) AC_OUTPUT [wzb@embedded testAutoMake]$ vi configure.in [wzb@embedded testAutoMake]$ clear [wzb@embedded testAutoMake]$ ls autoscan.log configure.in makefile.am src [wzb@embedded testAutoMake]$ cat configure.in # -*- Autoconf -*- # Process this file with autoconf to produce a configure script. AC_PREREQ(2.59) AC_INIT(testAutoMake, 0.1, wzb12008@sina.com) AC_CONFIG_SRCDIR([src/main.c]) AC_CONFIG_HEADER([config.h]) AM_INIT_AUTOMAKE(testAutoMake, 0.1) # Checks for programs. AC_PROG_CC # Checks for libraries. # Checks for header files. AC_HEADER_STDC # Checks for typedefs, structures, and compiler characteristics. # Checks for library functions. AC_CONFIG_FILES([makefile src/makefile]) AC_OUTPUT [wzb@embedded testAutoMake]$
3. 使用aclocal， 将configure.in中宏展开，生成alocal.m4 和临时加速文件autom4te.cache。
[wzb@embedded testAutoMake]$ pwd /home/wzb/workspace/testAutoMake [wzb@embedded testAutoMake]$ ls autoscan.log configure.in makefile.am src [wzb@embedded testAutoMake]$ aclocal [wzb@embedded testAutoMake]$ ls aclocal.m4 autom4te.cache autoscan.log configure.in makefile.am src [wzb@embedded testAutoMake]$ [wzb@embedded testAutoMake]$
4. 使用autoheader 生成config.h.in 文件。
[wzb@embedded testAutoMake]$ pwd /home/wzb/workspace/testAutoMake [wzb@embedded testAutoMake]$ ls aclocal.m4 autom4te.cache autoscan.log configure.in makefile.am src [wzb@embedded testAutoMake]$ autoheader [wzb@embedded testAutoMake]$ ls aclocal.m4 autoscan.log configure.in src autom4te.cache config.h.in makefile.am [wzb@embedded testAutoMake]$
5. 创建文件 ：README 、NEWS、AUTHORS、ChangeLog。touch README NEWS AUTHORS ChangeLog
[wzb@embedded testAutoMake]$ pwd /home/wzb/workspace/testAutoMake [wzb@embedded testAutoMake]$ ls aclocal.m4 autoscan.log configure.in src autom4te.cache config.h.in makefile.am [wzb@embedded testAutoMake]$ touch NEWS README AUTHORS ChangeLog [wzb@embedded testAutoMake]$ ls aclocal.m4 autom4te.cache ChangeLog configure.in NEWS src AUTHORS autoscan.log config.h.in makefile.am README [wzb@embedded testAutoMake]$ vi ChangeLog [wzb@embedded testAutoMake]$ cat ChangeLog 2012-04-07 Earl wzb12008@sina.com * Created [wzb@embedded testAutoMake]$
6. 执行automake -a 命令生成makefile.in 文件以及其他相关文件 install-sh, missing, depcomp, INSTALL , COPYING等。
[wzb@embedded testAutoMake]$ pwd /home/wzb/workspace/testAutoMake [wzb@embedded testAutoMake]$ ls aclocal.m4 autom4te.cache ChangeLog configure.in NEWS src AUTHORS autoscan.log config.h.in makefile.am README [wzb@embedded testAutoMake]$ automake -a configure.in: installing `./install-sh' configure.in: installing `./missing' src/makefile.am: installing `./depcomp' makefile.am: installing `./INSTALL' makefile.am: installing `./COPYING' [wzb@embedded testAutoMake]$ ls aclocal.m4 autoscan.log configure.in INSTALL makefile.in README AUTHORS ChangeLog COPYING install-sh missing src autom4te.cache config.h.in depcomp makefile.am NEWS [wzb@embedded testAutoMake]$
7. 执行 autoconf命令，生成configure脚本。
[wzb@embedded testAutoMake]$ pwd /home/wzb/workspace/testAutoMake [wzb@embedded testAutoMake]$ ls aclocal.m4 autoscan.log configure.in INSTALL makefile.in README AUTHORS ChangeLog COPYING install-sh missing src autom4te.cache config.h.in depcomp makefile.am NEWS [wzb@embedded testAutoMake]$ autoconf [wzb@embedded testAutoMake]$ ls aclocal.m4 autoscan.log configure depcomp makefile.am NEWS AUTHORS ChangeLog configure.in INSTALL makefile.in README autom4te.cache config.h.in COPYING install-sh missing src [wzb@embedded testAutoMake]$
8.执行./configure 生成 makefile 文件。
configure脚本的两个参数，-prefix 指定bin目录的父目录；另一个-host 指定处理器架构，交叉编译环境搭建时有用。
[wzb@embedded testAutoMake]$ pwd /home/wzb/workspace/testAutoMake [wzb@embedded testAutoMake]$ ls aclocal.m4 autoscan.log configure depcomp makefile.am NEWS AUTHORS ChangeLog configure.in INSTALL makefile.in README autom4te.cache config.h.in COPYING install-sh missing src [wzb@embedded testAutoMake]$ ./configure checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for gawk... gawk checking whether make sets $(MAKE)... yes checking for gcc... gcc checking for C compiler default output file name... a.out checking whether the C compiler works... yes checking whether we are cross compiling... no checking for suffix of executables... checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for gcc option to accept ANSI C... none needed checking for style of include used by make... GNU checking dependency style of gcc... gcc3 checking how to run the C preprocessor... gcc -E checking for egrep... grep -E checking for ANSI C header files... yes configure: creating ./config.status config.status: creating makefile config.status: creating src/makefile config.status: creating config.h config.status: executing depfiles commands [wzb@embedded testAutoMake]$ ls aclocal.m4 ChangeLog config.status depcomp makefile.am README AUTHORS config.h configure INSTALL makefile.in src autom4te.cache config.h.in configure.in install-sh missing stamp-h1 autoscan.log config.log COPYING makefile NEWS [wzb@embedded testAutoMake]$
9. 一下步骤基本与我们从源码编译安装应用的步骤相似。
首先，./configure -prefix bin目录所在的父目录（绝对路径）
接着 make ； 编译
最后 make install； 在bin目录中找到生成可执行程序测试。
[wzb@embedded testAutoMake]$ pwd /home/wzb/workspace/testAutoMake [wzb@embedded testAutoMake]$ ls aclocal.m4 autom4te.cache ChangeLog config.h.in config.status configure.in depcomp install-sh makefile.am missing README stamp-h1 AUTHORS autoscan.log config.h config.log configure COPYING INSTALL makefile makefile.in NEWS src [wzb@embedded testAutoMake]$ ./configure -prefix /home/wzb/w workspace/ wzb/ [wzb@embedded testAutoMake]$ ./configure -prefix /home/wzb/workspace/testAutoMake/ checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for gawk... gawk checking whether make sets $(MAKE)... yes checking for gcc... gcc checking for C compiler default output file name... a.out checking whether the C compiler works... yes checking whether we are cross compiling... no checking for suffix of executables... checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for gcc option to accept ANSI C... none needed checking for style of include used by make...

10. 当程序稳定了，可以通过命令 make dist ， 生成工程的发布文件。（还有 make distcheck命令）
[wzb@embedded testAutoMake]$ pwd
/home/wzb/workspace/testAutoMake
[wzb@embedded testAutoMake]$ ls

[wzb@embedded testAutoMake]$ make dist
{ test ! -d testAutoMake-0.1 || { find testAutoMake-0.1 -type d ! -perm -200 -exec chmod u+w {} ';' && rm -fr testAutoMake-0.1; }; }
mkdir testAutoMake-0.1
list='src'; for subdir in $list; do \
if test "$subdir" = .; then :; else \
test -d "testAutoMake-0.1/$subdir" \
|| mkdir -p -- "testAutoMake-0.1/$subdir" \
|| exit 1; \
distdir=`CDPATH="${ZSH_VERSION+.}:" && cd testAutoMake-0.1 && pwd`; \
top_distdir=`CDPATH="${ZSH_VERSION+.}:" && cd testAutoMake-0.1 && pwd`; \
(cd $subdir && \
make \
top_distdir="$top_distdir" \
distdir="$distdir/$subdir" \
distdir) \
|| exit 1; \
fi; \
done
make[1]: Entering directory `/home/wzb/workspace/testAutoMake/src'

[wzb@embedded testAutoMake]$ vi configure.in以上是是使用automake生成makefile的全过程，
想到了为什么，安装源码文件时，要先 ./configure -prefix ... ， 接着make， 接着make install 。很清楚了。。。
