Question

目前正在尝试在redhat上安装mysql2 gem。这是我在运行gem install

后得到的结果

gem install mysql2 -v 0.3.18 -- --with-mysql-config=/usr/bin/mysql_config


checking for ruby/thread.h... *** extconf.rb failed ***

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

看起来大多数得到类似错误的人都需要安装mysql dev / lib包。软件包已经安装并且是最新的。 mkmf.log文件如下所示：

日志文件中的错误是通过如下的健全性检查产生的：

typedef char ruby_check_sizeof_long[SIZEOF_LONG == sizeof(long) ? 1 : -1];

这个问题可能是什么原因？ gcc和mysql都是64位 - 有没有其他二进制文件/库可能导致这个问题？

对于记录，此系统上已安装了mysql2 gem的副本。它是由原始开发人员在几年前安装的，并且与/ usr / bin中的ruby安装相关联。我试图将项目迁移到使用由rbenv管理的ruby。从通过rbenv进行的干净的ruby安装中，bundle install将在我们的ubuntu盒子上完美运行，但是它会在这个系统上使用mysql2 gem运行。

在redhat上安装mysql2 gem
