你没有做这个吧

注意：如果你的源里没有gcc-toolset
。那你需要安装一个 yum 源进来比如阿里的 Centos8
。如果你连 yum 源也装不了你就直接把 rpm 包给下载下来。

门牌号：https://developer.aliyun.com/packageSearch?word=gcc-toolset

再或者你时间够多想玩点刺激的也可以考虑手工编译一个gcc出来。

我的环境已配置阿里centos 8的yum源，问题就是yum安装不上gcc-toolset。上面贴出的错误信息就yum安装gcc-toolset报的。我需要一个经过验证且有效的实践方案，没有时间在上面投入太多时间。谢谢的解答！

根据错误信息可以看出，gcc-toolset-11-gdb需要libpython3.6m.so.1.0()(64bit)的64位库，在您的系统中找不到这个库，导致gcc-toolset-11-gdb无法安装，进而导致整个gcc-toolset-11无法安装。这可能是由于Kylin 10所使用的Python版本较高，与gcc-toolset-11-gdb依赖项不兼容。为了解决这个问题，您可以考虑使用另一种安装方法，具体如下：

1. 安装依赖项：yum install wget libgcrypt-devel libxml2-devel libaio-devel cmake3 ncurses-devel bison perl
2. 下载并解压xtrabackup 8的源码包：wget https://github.com/percona/percona-xtrabackup/archive/refs/tags/8.0.26.tar.gz && tar -xzvf 8.0.26.tar.gz
3. 进入解压后的目录，运行cmake3进行编译：cmake3 . && make -j8
4. （可选）运行测试：make test
5. 安装xtrabackup 8：make install

@刺槐 谢谢你的解答。安装依赖包失败了，错误如下：

yum install wget libgcrypt-devel libxml2-devel libaio-devel cmake3 ncurses-devel bison perl
