如何在 Redhat 4.0 上安装支持 mysql2 的 Rails 3.0？

Question

当尝试在 Redhat 4.0 服务器上安装 Rails 3.0 时，“bundle install”在安装 mysql2 期间失败。

有可能解决这个问题吗？

“bundle install”命令返回以下输出：

Answer 1

您是否安装了所有合适的开发库？例如 libmysqlclient-16-dev 或类似的东西？

Answer 2

是的，但我相信它太旧了？

~/rails/trial# rpm -qa|grep mysql
mysqlclient10-devel
mysqlclient10
mysql-devel
mysql-server
mysql

然而，就 RHEL4 而言，一切似乎都是最新的（并且升级并不是真正的选择）

~/rails/trial# up2date --showall|grep mysql
mysql-4.1.22-2.el4_8.3.x86_64
mysql-bench-4.1.22-2.el4_8.3.x86_64
mysql-devel-4.1.22-2.el4_8.3.x86_64
mysql-server-4.1.22-2.el4_8.3.x86_64
mysqlclient10-3.23.58-4.RHEL4.1.x86_64
mysqlclient10-devel-3.23.58-4.RHEL4.1.x86_64
