PostgreSQL数据库源码安装第一步——configure脚本分析（初始化）

　　下面的代码是用来初始化输出到Makefile中变量，比如ac_default_prefix、ac_clean_files、ac_cnofig_libobj_dir等。

 1 # Initializations.
 2 ac_default_prefix=/usr/local
 3 ac_clean_files=
 4 ac_config_libobj_dir=.
 5 LIBOBJS=
 6 cross_compiling=no
 7 subdirs=
 8 MFLAGS=
 9 MAKEFLAGS=
10 SHELL=${CONFIG_SHELL-/bin/sh}
11 # Identity of this package.

13 PACKAGE_TARNAME='postgresql'
14 PACKAGE_VERSION='8.4.1'
15 PACKAGE_STRING='PostgreSQL 8.4.1'
16 PACKAGE_BUGREPORT='pgsql-bugs@postgresql.org'
17 ac_unique_file="src/backend/access/common/heaptuple.c"
18 ac_default_prefix=/usr/local/pgsql

初始化由options设置的一些变量

初始化目录选项

 3 # and all the variables that are supposed to be based on exec_prefix
 4 # by default will actually change.
