Mysql 从源安装找不到devtoolset gcc

当我试图从我的

Centos-6.8

上的源文件安装

mysql-8.0.11

时，

cmake

抱怨需要GCC 4.8或更新版本

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
      -DMYSQL_DATADIR=/usr/local/mysql/data \
      -DENABLED_LOCAL_INFILE=1 \

似乎cmake让我升级编译器，所以我通过下面的

yum

命令完成了升级

cd /etc/yum.repos.d
wget http://linuxsoft.cern.ch/cern/scl/slc6-scl.repoyum -y --nogpgcheck

然而，它仍然不起作用

检查gcc和g++的版本时，我看到如下所示

cd /etc/yum.repos.d
wget http://linuxsoft.cern.ch/cern/scl/slc6-scl.repoyum -y --nogpgcheck 
install devtoolset-3-gcc devtoolset-3-gcc-c++

我错过了什么

如果您有任何建议，我们将不胜感激。

请在您的cmake系列中附加以下内容：

---

-DCMAKE\u C\u COMPILER=/opt/rh/devtoolset-7/root/usr/bin/gcc-DCMAKE\u CXX\u COMPILER=/opt/rh/devtoolset-7/root/usr/bin/g++

/p>

-DCMAKE\u链接器=…/ld

可能也很有用，尽管没有它也可以工作。
