CentOS下编译PHP 7
在CentOS下编译PHP 7的过程中遇到很多错误，在此做个笔记，也供网友参考。总的来说是编译的时候报错，先看编译log，缺少什么依赖，然后安装相应依赖包，重新编译。
编译环境
- OS：
shell> cat /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m
- gcc
shell> gcc --version
gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-11)
Copyright (C) 2010 Free Software Foundation, Inc.
- autoconf
shell> autoconf --version
autoconf (GNU Autoconf) 2.69
Copyright (C) 2012 Free Software Foundation, Inc.
- make
shell> make --version
GNU Make 3.81

安装依赖
sudo yum install git gcc gcc-c++ libxml2-devel pkgconfig openssl-devel bzip2-devel curl-devel libpng-devel libjpeg-devel libXpm-devel freetype-devel gmp-devel libmcrypt-devel mariadb-devel aspell-devel recode-devel autoconf bison re2c libicu-devel
编译
- 下载php源码发布包：
shell> wget https://www.php.net/distributions/php-7.3.5.tar.gz
shell>tar zxvf php-7.3.5.tar.gz
- 设置编译选项
可以先通过./configure --help查看编译选项，由于编译选项比较多，放到build.sh脚本中：
shell> cat build.sh
#!/bin/bash
./buildconf --force
./configure --prefix=/home/dev/opt/php7 \
--with-config-file-path=/home/dev/opt/php7/etc \
--with-config-file-scan-dir=/home/dev/opt/php7/etc/conf.d \
--enable-bcmath \
--with-bz2 \
--with-curl \
--enable-filter \
--enable-fpm \
--with-gd \
--with-freetype-dir \
--with-jpeg-dir \
--with-png-dir \
--enable-intl \
--enable-mbstring \
--enable-mysqlnd \
--with-mysql-sock=/var/lib/mysql/mysql.sock \
--with-mysqli=mysqlnd \
--with-pdo-mysql=mysqlnd \
--with-pdo-sqlite \
--disable-phpdbg \
--disable-phpdbg-webhelper \
--enable-opcache \
--with-openssl \
--enable-simplexml \
--with-sqlite3 \
--enable-xmlreader \
--enable-xmlwriter \
--enable-zip \
--with-zlib \
--disable-fileinfo
- 编译
shell> chmod +x build.sh
shell> sh build.sh
shell> make & make install
编译错问题整理
g++: internal compiler error: Killed (program cc1plus)
Please submit a full bug report
我的机器内存比较小，编译的时候内存耗尽直接被系统kill掉了。使用交换分区创建一个2G的内存了。
sudo dd if=/dev/zero of=/swapfile bs=64M count=16
sudo mkswap /swapfile
sudo swapon /swapfile
# 编译完了再释放掉
sudo swapoff /swapfile
sudo rm /swapfileile
同时在编译选项中加入--disable-fileinfo禁用fileinfo，见上面build.sh脚本。
buildconf: autoconf version 2.63 found.
You need autoconf version 2.68 or newer installed to build PHP from Git.

# autoconf版本太低，需要升级一下，yum源没有更高版本，采用源码安装:

#可以使用yum安装
shell> sudo yum install icu icu-devel

#需要注意，源码安装icu到/usr/local下，上面build.sh脚本需要手动指定icu的安装目录`--with-icu-dir=/usr/local`

#安装libzip库
shell> sudo yum install libzip libzip-devel

#libzip的版本过低，yum源没有更高版本，采用源码安装
shell> wget https://nih.at/libzip/libzip-1.2.0.tar.gz

#找不到/usr/local/include/zip.h，估计是源码安装的时候，没有把zipconf.h文件放到/usr/local/include目录下，手动copy一下:
shell>>cp -v /usr/local/lib/libzip/include/zipconf.h /usr/local/include/zipconf.h
