我下载了nginx的tar包，然后进行安装

发现pcre不存在
然后下载pcre 的tar包到/home/temp
然后configure&make&make install
安装后发现要用的是源码，而不是安装
就把源码复制到/usr/local/src/下，
然后命令：

./configure  --prefix=/usr/local/nginx --with-pcre=/usr/local/src/pcre-8.40

接着

[root@nginx-server nginx-1.13.8]# make
make -f objs/Makefile
make[1]: Entering directory `/home/temp/nginx-1.13.8'
cd /usr/local/src/pcre-8.40 \
        && if [ -f Makefile ]; then make distclean; fi \
        && CC="cc" CFLAGS="-O2 -fomit-frame-pointer -pipe " \
        ./configure --disable-shared 
make[2]: Entering directory `/usr/local/src/pcre-8.40'

         The 'aclocal' program is part of the GNU Automake package:

怎么办啊？
