今天在Centos7.6系统下编译安装php8.0，报如下错误：

make: *** [sapi/cli/php] 错误 1

报这个错误的原因，是因为oniguruma安装不正确。

安装php时，会执行如下命令：

./configure \
--prefix=/usr/local/php7 \
--with-config-file-path=/etc \
--with-mysql \
--with-mysqli \
--with-mysql-sock \
--enable-pdo \
--with-pdo-mysql \
--with-gd \
--with-iconv  \
--with-curl \
--with-zlib \
--enable-xml \
--enable-bcmath \
--enable-shmop \
--enable-sysvsem \
--enable-inline-optimization \
--enable-mbregex \
--enable-mbstring \
--enable-gd-native-ttf \
--with-openssl \
--enable-pcntl \
--enable-sockets \
--with-xmlrpc \
--enable-zip \
--enable-soap \
--without-pear \
--with-gettext \
--enable-session \
--enable-fpm \
--with-bz2
--with-jpeg-dir=/usr/local/jpeg \
--with-freetype-dir \
--with-png-dir=/usr/local/pngp 

其中--enable-mbstring会涉及到一些正则表达式的处理，需要oniguruma插件的支持。

关于oniguruma的安装方式有两种：

第一种：rpm安装oniguruma

yum -y install oniguruma-6.7.0-1.el7.x86_64.rpm

yum -y install oniguruma-devel-6.7.0-1.el7.x86_64.rpm

后面文件是我先下载传到服务器里的。

oniguruma-6.7.0-1.el7.x86_64.rpm

oniguruma-devel-6.7.0-1.el7.x86_64.rpm

这种方式没能解决本文开头的报错。

第二种：源码编译安装oniguruma

wget https://github.com/kkos/oniguruma/archive/v6.9.4.tar.gz -O oniguruma-6.9.4.tar.gz
tar -xzvf oniguruma-6.9.4.tar.gz
cd oniguruma-6.9.4
./configure --prefix=/usr --libdir=/lib64
make && make install

第一次编译时，没有带上--libdir这部分仍然报错，第二次带上了重新编译，php编译就ok了。

php编译过程：

一开始把依赖都装上，直接执行下面命令

yum -y install wget vim pcre pcre-devel openssl openssl-devel libicu-devel gcc gcc-c++  autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel ncurses ncurses-devel curl curl-devel krb5-devel libidn libidn-devel openldap openldap-devel nss_ldap jemalloc-devel cmake boost-devel bison automake libevent libevent-devel gd gd-devel libtool* libmcrypt libmcrypt-devel mcrypt mhash libxslt libxslt-devel readline readline-devel gmp gmp-devel libcurl libcurl-devel openjpeg-devel

configure成功，会看到如下界面：

+--------------------------------------------------------------------+

Thank you for using PHP.

或许由于Centos系统版本原因，上面configure命令好多选项是不存在的。因此除了上面成功提示，还会有如下警告提示：

configure: WARNING: unrecognized options: --with-mysql, --with-gd, --enable-inline-optimization, --enable-gd-native-ttf, --with-xmlrpc, --enable-zipk

mysql在php7中就废弃了（现在用mysqli），很好理解。至于gd为何也不支持了，得另外继续了解了。

make install成功，就会显示配置及脚本各个文件所在的位置，例如如下：
