在 CentOS 5.X 上安装 libxml2 2.7.X

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

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

我尝试通过以下方式安装：

# 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.

更新 glibc 是否安全？或者从源代码安装 libxml2？

答案1

确保你已经安装了开发工具：

yum groupinstall "Development Tools"

获取 src rpm：

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

由于 rpm 版本差异，您将无法直接调用 rpmbuild，因此让我们简化一下：

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

然后：

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

此时您可能会被提示输入一些依赖项（如果是这样，则仅输入yum install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 CentOS 5 机器上进行了测试，并且构建良好），生成的 RPM 将位于：

/usr/src/redhat/RPMS/arch

其中“arch”是 x86_64 或 i386，具体取决于您的系统。您可以yum localinstall --nogpgcheck从那里获取软件包。

获取 SRPM 并使用 mock 重建它。
