编译命令
适合于php ver 5 到 php 7.4.4，不同的版本部分参数不生效，编译时会自动忽略，该编译参数已包含常用的库。

GD库没有安装
checking whether to enable JIS-mapped Japanese font support in GD... no checking for fabsf... yes checking for floorf... yes configure: error: jpeglib.h not found
解决办法
yum install libjpeg.x86_64 libpng.x86_64 freetype.x86_64 libjpeg-devel.x86_64 libpng-devel.x86_64 freetype-devel.x86_64 libjpeg-turbo-devel -y
PHP编译出错：--enable-opcache=no
错误消息
configure: error: Don't know how to define struct flock on this system, set --enable-opcache=no
出错的原因：
因libmcrypt是手动编译的，需要将这个编译后的库文件目录加入到/etc/ld.so.conf.d/local.conf文件中：
vim /etc/ld.so.conf.d/local.conf /usr/local/lib ldconfig
LDAP编译不通过的解决办法
故障现象：
configure: error: Cannot find ldap.h
解决办法：
yum install openldap-devel -y
如果安装了openldap-devel1还是不行，尝试继续下面的命令
cp -frp /usr/lib64/libldap* /usr/lib/
如果上述都无法解决，请留言
解决 utf8_mime2text() has new signature 问题
configure: error: utf8_mime2text() has new signature, but U8T_CANONICAL is missing. This should not happen. Check config.log for additional information. yum install libc-client-devel
解决 libxslt 问题
