php - 在 Ubuntu Server 12.04 上编译 libvirt-php 时出错

Question

我正在尝试在我的 ubuntu 服务器中设置 libvirt-php 以使用 PHP API 进行一些测试。我正在执行此过程:

sudo apt-get install libvirt-dev xsltproc libxml2-dev libxml2  
cd ~ 
git clone git://libvirt.org/libvirt-php.git libvirt-php  
cd libvirt-php  
sudo sh autogen.sh  
sudo ./configure  
sudo make  
sudo make install  
sudo service apache2 restart

我还为 ubuntu 安装了 php5-dev 和 xmllint 包，但是当我转到第 7 行时:make 我得到了这些错误:

所以我无法编译。有帮助吗？

git://libvirt.org/libvirt-php 中的 require 版本似乎不正确

它显示LIBVIRT_REQUIRED=0.6.2，但是在Ubuntu 12.04使用的0.9.8版本中，变量virDomainGetMetadata和VIR_DOMAIN_VCPU_GUEST没有定义，导致了这个错误。

(如果你想查询你的libvirt-dev版本是什么，输入$dpkg-query -s libvirt-dev)

你可以试试这个:

1. 升级你的 Ubuntu

   最新版本的 Ubuntu 支持具有变量 virDomainGetMetadata 的新 libvirt-dev

   https://launchpad.net/ubuntu/+source/libvirt

2. 使用 libvirt-php 0.4.8

   我用它来解决问题，但是又出现了一个问题，它不支持libvirt_domain_get_metadata。

   以下步骤展示了如何使用 libvirt-php 0.4.8:

   访问http://libvirt.org/php/downloads.html

   $wget http://libvirt.org/sources/php/libvirt-php-0.4.8.tar.gz
   $tar -xvf libvirt-php-0.4.8.tar.gz
   $cd libvirt-php-0.4.8
   $./configure
   $make
   

   然后检查没有其他问题

   $sudo make install
   $sudo /etc/init.d/apache2 restart
