 一、zephir 编译遇到的错误

安装

git clone https://github.com/phalcon/zephir

/-/ -c

编译

www@ubuntu4:~$ zephir build

────────────────────────────────────────────────────────────
  The Zephir Parser extension is not loaded.
  Note: Zephir no longer distributed with internal parser.
  
  To install latest stable Zephir Parser please refer to:
  https://github.com/phalcon/php-zephir-parser
────────────────────────────────────────────────────────────

二、php-zephir-parser 安装

git clone git://github.com/phalcon/php-zephir-parser.git

php7.0-dev 安装报错

www@ubuntu4:~$ sudo apt-get install php7.0-dev gcc make re2c autoconf
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package php7.0-dev
E: Couldn‘t find any package by regex ‘php7.0-dev‘

如何让解决

1、php7的存储库的问题，添加php7 ppa

sudo add-apt-repository ppa:ondrej/php

2、更新库

sudo apt-get update

3、现在做一个搜索来确认php7是有的

sudo apt search php7

重新安装，则不会报错

www@ubuntu4:~$ sudo apt-get install php7.0-dev gcc make re2c autoconf
Reading package lists... Done
Building dependency tree       
Reading state information... Done
gcc is already the newest version.
gcc set to manually installed.
make is already the newest version.
re2c is already the newest version.
The following extra packages will be installed:
  automake autotools-dev debhelper dh-apparmor dh-php gettext intltool-debian
  libasprintf-dev libgettextpo-dev libgettextpo0 liblist-moreutils-perl
  libltdl-dev libmail-sendmail-perl libssl1.1 libsys-hostname-long-perl
  libtool libunistring0 m4 php-common php-pear php-xml php7.0-cli
  php7.0-common php7.0-json php7.0-opcache php7.0-readline php7.1-common
  php7.1-xml pkg-php-tools po-debconf shtool xml2

开始编译

www@ubuntu4:~/ffmpeg_videos/php-zephir-parser$ sudo ./install
Generating parser...

                   982 states, 0 parser table entries, 0 conflicts

 -c /home/www/ffmpeg_videos/php-zephir-parser/zephir_parser.c  -fPIC -DPIC -o .libs/zephir_parser.o

编译完成

查找.so 文件路径

www@ubuntu4:~ sudo find / -name zephir_parser.so
/usr/lib/php/20151012/zephir_parser.so

配置php.ini 文件

sudo vim /opt/php-7.1.9/etc/php.ini

添加一下内容：

[Zephir Parser]
extension=/usr/lib/php/20151012/zephir_parser.so

安装完毕

三、重新编译，出现同样的错误：

www@ubuntu4:~/ffmpeg_videos/zephir-framework/lib$ zephir build

────────────────────────────────────────────────────────────
  The Zephir Parser extension is not loaded.
  Note: Zephir no longer distributed with internal parser.
  
  To install latest stable Zephir Parser please refer to:
  https://github.com/phalcon/php-zephir-parser
────────────────────────────────────────────────────────────

好纠结啊，如何解决：

sudo ln -s /opt/php-7.0.9/bin/php /usr/bin/php

继续，Ok 了：

www@ubuntu4:~/ffmpeg_videos/zephir-framework/zephirlib$ zephir build
Compiling...
Installing...
Extension installed!
Add extension=zephirlib.so to your php.ini
