Linux Squid源代码目录重命名给出；A局部-1.14“；清除过程中缺少错误

我有一个squid源代码目录，它适用于

/configure&&makeclean

，如下所示

cd /opt/squid-3.5.4
./configure && make clean

现在，当我创建dir的副本并尝试执行

/configure&&makeclean

时，我得到一个错误

cp -r /opt/squid-3.5.4 /opt/squid-3.5.4_BKUP
cd /opt/squid-3.5.4_BKUP
./configure && make clean
.....

WARNING: 'aclocal-1.14' is missing on your system.
         You should only need it if you modified 'acinclude.m4' or
         'configure.ac' or m4 files included by 'configure.ac'.
         The 'aclocal' program is part of the GNU Automake package:
         <http://www.gnu.org/software/automake>
         It also requires GNU Autoconf, GNU m4 and Perl in order to run:
         <http://www.gnu.org/software/autoconf>
         <http://www.gnu.org/software/m4/>
         <http://www.perl.org/>
make[1]: *** [aclocal.m4] Error 127
make[1]: Leaving directory `/opt/squid-3.5.4_BKUP/libltdl'
make: *** [clean-recursive] Error 1

它说缺少

aclocal-1.14

，但在dir

/opt/squid-3.5.4

中，它可以与当前的aclocal版本配合使用

有人能告诉我怎样才能在我的电脑里建立（/make）吗

PS：在一些谷歌搜索之后，我试着做下面的事情

cd /opt/squid-3.5.4_BKUP
touch configure.ac aclocal.m4 configure Makefile.am Makefile.in
autoreconf -ivf

---

但是运气不好。

看起来我不得不这么做：

cd /opt/squid-3.5.4_BKUP/libltdl/
touch configure.ac aclocal.m4 configure Makefile.am Makefile.in

cd /opt/squid-3.5.4_BKUP/libltdl/
touch configure.ac aclocal.m4 configure Makefile.am Makefile.in
