编译 pacman 源代码

Step 1. 从下面的网址下载 pacman 源代码


比如下载 到某个文件夹 pacman/

然后解压缩

tar xzvf pacman-4.0.3.tar.gz

在 pacman/ 目录下得到了一个 pacman-4.0.3/ 的子文件夹, 我们列出其中的内容.

[haifeng@arch pacman-4.0.3]$ ls
acinclude.m4  config.rpath  depcomp  install-sh   missing        scripts/
AUTHORS       config.sub    doc/      lib/          mkinstalldirs  src/
autoclean.sh  configure.ac  etc/      ltmain.sh    NEWS           test/
autogen.sh    contrib/       HACKING  m4/           proto/          TRANSLATORS
config.guess  COPYING       INSTALL  Makefile.am  README         valgrind.supp

执行其中的 autogen.sh 命令,

[haifeng@arch pacman-4.0.3]$ ./autogen.sh
+ aclocal -I m4 --install
+ autoheader
+ automake --foreign
configure.ac:138: warning: The 'AM_PROG_MKDIR_P' macro is deprecated, and will soon be removed.
configure.ac:138: You should use the Autoconf-provided 'AC_PROG_MKDIR_P' macro instead,
configure.ac:138: and use '$(MKDIR_P)' instead of '$(mkdir_p)'in your Makefile.am files.
src/pacman/Makefile.am:20: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS')
src/util/Makefile.am:14: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS')
+ autoconf

将生成 configure 和其他文件, 下面是多出来的文件(夹).

aclocal.m4autom4te.cache/config.h.in
configure
Makefile.in

然后执行 configure

安装 asciidoc 软件包, 并重新运行 ./configure

[haifeng@arch pacman-4.0.3]$ sudo pacman -S asciidoc

--------------------------------------------------

[haifeng@arch pacman-4.0.3]$ ./configure
[haifeng@arch pacman-4.0.3]$ cd doc
[haifeng@arch pacman-4.0.3]$ make

结果比原来 doc/ 中多了十个文件.

libalpm.3, makepkg.8, makepkg.conf.5, pacman-key.8, pacman.8,

pacman.conf.5, PKGBUILD.5, pkgdelta.8, repo-add.8, vercmp.8

多了下面几个文件, 特别是 Makefile 和 config.h. 其中 config.h 被 src/ 中好多文件包含.

config.h
config.log
config.status
libtool
Makefile
stamp-h1

接下来, 就可以 make, sudo make install 来安装了.

注:

打开 config.h 文件, 就会发现其头两行写着该文件及 config.h.in 的来源.
/* config.h.  Generated from config.h.in by configure.  */
/* config.h.in.  Generated from configure.ac by autoheader.  */
