背景
前几天在mac上跑workrman，由于workerman需要开启多个进程，多进程需要pcntl扩展的支持，我之前那个brew安装的php71没有这个扩展，就直接卸载了php71，然后想下载源码编译安装php7的更高版本，也可以更自由的安装扩展。
源码编译安装（php-7.2.7）
问题一
configure: WARNING: you should use --build, --host, --target configure: WARNING: invalid host type: configure: WARNING: you should use --build, --host, --target configure: WARNING: invalid host type: --enable-fpm configure: WARNING: you should use --build, --host, --target configure: WARNING: invalid host type: --with-MySQLi configure: WARNING: you should use --build, --host, --target configure: WARNING: invalid host type: --with-pdo-mysql configure: WARNING: you should use --build, --host, --target configure: WARNING: invalid host type: --with-iconv-dir configure: WARNING: you should use --build, --host, --target configure: WARNING: invalid host type: --with-eeeetype-dir configure: WARNING: you should use --build, --host, --target configure: WARNING: invalid host type: --with-zlib configure: WARNING: you should use --build, --host, --target configure: WARNING: invalid host type: --with-jpeg-dir configure: WARNING: you should use --build, --host, --target configure: WARNING: invalid host type: --with-png-dir configure: error: invalid variable name: ` --with-libxml-dir'
解决：都是因为—with前面多了个空格
问题二
Sorry, I cannot run apxs. Possible reasons follow: 1. Perl is not installed 2. apxs was not found. Try to pass the path using --with-apxs2=/path/to/apxs 3. Apache was not built using --enable-so (the apxs usage page is displayed)
解决办法
brew install httpd find / -name apxs Centos下执行 yum install -y httpd-devel
查找到apxs文件路径，然后修改编译参数如下
--with-apxs2=/usr/local/bin/apxs
问题三
checking if the location of ZLIB install directory is defined... no ； configure: error: Cannot find libz.
解决办法
brew install zlib find / -name lib
加上参数
--with-zlib-dir=/usr/local/Cellar/zlib/1.2.11
问题四
configure: error: Cannot locate header file libintl.h
原因是没有gettext
解决办法：
$PHP_GETTEXT /usr/local /usr; do
configure文件改为
for i in $PHP_GETTEXT /usr/local /usr /usr/local/opt/gettext; do
问题五
configure: error: Please specify the install prefix of iconv with --with-iconv=
解决办法，编译参数中加上
\--with-iconv=/usr/local/Cellar/libiconv/1.15
问题六
checking for libiconv in -liconv... no checking for iconv in -liconv... no configure: error: Please reinstall the iconv library.
【最终卡在了这里，没解决。然后编译安装就没有成功】
最后解决到问题五的时候的编译安装命令如下：
./configure --prefix=/usr/local/php/7.2.7\—with-config-file-path=/usr/local/php/7.2.7/etc \--with-config-file-scan-dir=/usr/local/php/7.2.7/etc/conf.d \--with-apxs2=/usr/local/bin/apxs \--with-zlib-dir=/usr/local/Cellar/zlib/1.2.11 \--enable-fpm \--with-fpm-user=www \--with-fpm-group=www \--with-mysqli \--with-pdo-mysql \--with-iconv=/usr/local/Cellar/libiconv/1.15 \--with-eeeetype-dir \--with-zlib \--with-jpeg-dir \--with-png-dir \--with-libxml-dir=/usr/bin/xml2-config \--enable-xml \--disable-rpath \--enable-bcmath \--enable-shmop \--enable-sysvsem \--enable-inline-optimization \--with-curl \--enable-mbregex \--enable-mbstring \--with-mcrypt \--enable-ftp \--with-gd \--enable-gd-native-ttf \--with-onsnssl \--with-mhash \--enable-pcntl \--enable-sockets \--with-xmlrpc \--enable-zip \--enable-soap \--without-pear \--with-gettext \--disable-fileinfo \--enable-maintnener-zts \--enable-mysqlnd
brew安装
1.搜索brew中的php
brew search php
出现了：php@5.6 php@7.1 php@7.0
2.然后安装了php7.0
brew install php70
3.将php设置系统环境变量
find / -name php # 先找到php执行文件 cp /usr/local/Cellar/php@7.0/7.0.30_1/bin/php /usr/bin # 将php执行文件放到/usr/bin/文件夹中
最后
通过源码编译安装没有成功，还是brew install安装成功。
