如何在 CentOS 7 中将 libxml2 升级到版本 2.9.9？

Question

我的步骤：

下载：

# wget ftp://xmlsoft.org/libxml2/libxml2-2.9.9.tar.gz

解压存档：

# tar -zxvf libxml2-2.9.9.tar.gz

进入目录：

# cd libxml2-2.9.9/

做一些奇怪的事情：

# ./configure && make && make install

此命令返回错误：

命令：php -i | grep libxml 产生以下结果：

PHP Warning:  Unknown: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in Unknown on line 0
libxml
libxml2 Version => 2.9.1
OLDPWD => /root/libxml2-2.9.9
_SERVER["OLDPWD"] => /root/libxml2-2.9.9

命令：yum update-to libxml2-2.9.9 - 不工作。

Answer 1

配置：错误：在 $PATH 中找不到可接受的 C 编译器

解决方案：# yum install gcc-c++ ...即同时安装 gcc 和 g++ 也将安装所有使 gcc 完全工作的包。

注意：./configure 单独安装到 /usr/local/，并且不会更新当前版本 2.9.1 。要求是

tar xvf libxml2-2.9.9.tar.gz
cd libxml2-2.9.9/
./configure --prefix=/usr --libdir=/usr/lib64
make
# make install
