在CentOS 5.X上安装libxml2 2.7.X

CentOS随附libxml2-2.6.26。我必须至少安装2.7.X版本。

我从XMLSOFT（http://xmlsoft.org/sources/）下载了libxml2，libxml2-devel和libxml2-python（2.7.8）的RPM 。

我正在尝试以这种方式安装它：

# yum localinstall libxml2-2.7.8-1.x86_64.rpm libxml2-devel-2.7.8-1.x86_64.rpm libxml2-python-2.7.8-1.x86_64.rpm

我得到：

 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                    package-cleanup --dupes
                    rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.

是否也可以安全更新glibc？还是从源代码安装libxml2？

确保已安装开发工具：

yum groupinstall "Development Tools"

抓住src rpm：

wget http://xmlsoft.org/sources/libxml2-2.7.8-1.src.rpm

由于rpm版本不同，您将无法直接调用rpmbuild，因此请短路：

rpm -ivh libxml2-2.7.8-1.src.rpm --nomd5

然后：

rpmbuild -ba /usr/src/redhat/SPECS/libxml2.spec

此时可能会提示您提供一些依赖项（如果是，则仅yum install是有问题的依赖项，然后重新运行rpmbuild -ba上面的命令）。

假设您的构建成功完成（我刚刚在此处的CentOS 5盒上对此进行了测试，并且构建良好），则生成的RPM将位于：

/usr/src/redhat/RPMS/arch

其中，“ arch”是x86_64还是i386，具体取决于您的系统。您可以yum localinstall --nogpgcheck从那里打包。

抓住SRPM并使用模拟重建它。
