我尝试将mysql advanced 5.7.19安装到Solaris SPARC 64bit上的非默认位置
非默认位置：/opt/app/mysql
但面临以下错误：
在pkgadd期间： ld.so.1：mysqld：fatal：libstdc ++。so.6：找不到版本'GLIBCXX_3.4.20'（文件bin / mysqld需要）
在mysql_install_db期间：ld.so.1：mysql_install_db：致命：libstdc ++。so.6：找不到版本'GLIBCXX_3.4.20'（文件mysql_install_db需要）
以下是我的步骤：
# working directory: /export/home/admin
root@host:/export/home/admin# cat /var/sadm/install/admin/custom
basedir=/opt/app/$PKGINST
root@host:/export/home/admin# pkgadd -a custom -d mysql-advanced-5.7.19-solaris11-sparc-64bit.pkg
...
Executing postinstall script.
