Linuxでmakefileを自動的に生成するツール:automake,autoconfでmakefileを生成する一般的なプロセス


Linuxでmakefileを自動的に生成するツール:automake,autoconfでmakefileを生成する一般的なプロセス


1.プロジェクトディレクトリと各ディレクトリの下のmakefileを作成する.am.エンジニアリングの名前は、一般的に最終生成アプリケーションの名前と同じです.
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,
", result); printf("test.......makefile ........ok
"); 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.autoscanコマンドにより、autoconfのテンプレートを作成し、configureを生成する.inファイル.
まず、エンジニアリングディレクトリでautoscanコマンドを実行することにより、autoconfのテンプレートファイルconfigureを生成する.scanファイル、configureと名前を変更します.in.
2つの変更が必要です.
 (1). これをinファイルの文:AC_INIT(FULL-PAKAGE-NAME,VERSION,BUG-REPORT-ADDRESS)の
FULL-PaKAGE-NAME:あなたが割り当てた開発パッケージの名前に置き換えます:本プロジェクトのようです:test_AutoMake;
VERSION:開発されたバージョン番号、一般フォーマット:マスターバージョン番号.バージョン番号から.例えば0.1;
BUG-REPORT-ADDRESS:バグを送信するメールアドレス:[email protected].
 (2). もう1つ追加します:AM_INIT_AUTOMAKE(testAutoMake,0.1)すなわちAM_INIT_AUTOMAKE(package_name, version);
Automakeを初期化するために使用します.
[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 -*-

3.aclocalを使用してconfigure.in中マクロ展開、alocalを生成する.m 4と一時加速ファイルautom 4 te.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.autoheaderでconfigを生成する.h.inファイル.
[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.ファイル作成:README、NEWS、AUTHERS、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

[wzb@embedded testAutoMake]$ vi ChangeLog
[wzb@embedded testAutoMake]$ cat ChangeLog
2012-04-07 Earl [email protected]
        * Created
[wzb@embedded testAutoMake]$

6.automake-aコマンドを実行してmakefileを生成する.inファイルその他関連ファイルinstall-sh,missing,depcomp,INSTALL,COPYINGなど.
[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.autoconfコマンドを実行し、configureスクリプトを生成します.
[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.実行./configureはmakefileファイルを生成します.
configureスクリプトの2つのパラメータ、-prefixはbinディレクトリの親ディレクトリを指定します.もう1つの-hostはプロセッサアーキテクチャを指定し、クロスコンパイル環境の構築に役立ちます.
[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

9.次の手順は、基本的にソースコードからアプリケーションをコンパイルしてインストールする手順と似ています.
まず、./configure-prefix binディレクトリが存在する親ディレクトリ(絶対パス)
続いてmake;コンパイル
最後にmake install;binディレクトリに実行可能なプログラムテストの生成を見つけます.

以上はautomakeを用いてmakefileを生成する全過程であり、
なぜかと思うと、ソースファイルをインストールするときは、まず./configure -prefix ... , 次にmake、次にmake install.よくわかりました...
