在 64 位 CentOS 上安装 Mysql Ruby gem

Question

我在 64 位 CentOS 机器上安装 mysql ruby​​ gem 时遇到问题。

[jacekb@vitaidealn ~]$ uname -a
Linux vitaidealn.local 2.6.18-92.el5 #1 SMP Tue Jun 10 18:51:06 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux

安装了 Mysql 和 mysql-devel 包。Mysql_config 提供以下路径：

Usage: /usr/lib64/mysql/mysql_config [OPTIONS]
Options:
    --cflags         [-I/usr/include/mysql -g -pipe -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -fno-strict-aliasing -fwrapv]
    --include        [-I/usr/include/mysql]
    --libs           [-L/usr/lib64/mysql -lmysqlclient -lz -lcrypt -lnsl -lm -L/usr/lib64 -lssl -lcrypto]
    --libs_r         [-L/usr/lib64/mysql -lmysqlclient_r -lz -lpthread -lcrypt -lnsl -lm -lpthread -L/usr/lib64 -lssl -lcrypto]
    --socket         [/var/lib/mysql/mysql.sock]
    --port           [3306]
    --version        [5.0.45]
    --libmysqld-libs [-L/usr/lib64/mysql -lmysqld -lz -lpthread -lcrypt -lnsl -lm -lpthread -lrt -L/usr/lib64 -lssl -lcrypto]

尝试安装：

[jacekb@vitaidealn ~]$ gem install mysql -- --with-mysql-include=/usr/include/mysql --with-mysql-libs=/usr/lib64/mysql
...
ERROR:  Error installing mysql:
    ERROR: Failed to build gem native extension.

    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.

我将不胜感激任何帮助。谢谢阅读 ：）。

我认为您需要 mysql-client 的开发包。尝试安装它：

yum install mysql-devel
