ruby-on-rails - 用mingw编译mysql2时出现段错误

Question

当我尝试创建 Rails 服务器时，这就是我得到的结果。它立即运行超过 500 行代码并返回此消息。这是我的第一个 Ruby on Rails 项目。我对编码也很陌生。如果可能的话，希望得到一些帮助。谢谢你!

Answer 1

按照 Dave Schweisguth 的关于 ruby​​ bug 的回答，并执行 Heesob Park 评论中描述的步骤，我可以让 mysql2 gem 工作。谢谢你们分享这个。

引用 Heesob 评论:

The libmysql.lib included in the MySQL Connector/C 64 bit is not compatible with the mingw64-gcc compiler.

You need to generate mingw64 compatible libmysql.lib file.

为了创建兼容的 libmysql.lib 文件，我执行了以下步骤: (我正在运行 Win8.1 x64 和 Ruby 2.0.0p481 [x64-mingw32])

1) 下载此 zip 文件 https://structure-svm-map.googlecode.com/files/svm-map-win.zip并将其提取到 c:\tmp\svm-map

2) 从http://dev.mysql.com/get/Downloads/Connector-C/mysql-connector-c-6.1.3-winx64.zip下载Mysql C/Connector 6.1并将其解压到c:\tmp\mysql

3)打开CMD提示符

4) cd\tmp\svm-map\python-mingw-lib

5) gendef.exe\tmp\mysql\lib\libmysql.dll

6) 移动 libmysql.def\tmp\mysql\lib

7) cd\tmp\mysql\lib

8) \Ruby200-x64\DevKit\mingw\bin\dlltool -v --dllname libmysql.dll --def libmysql.def --output-lib libmysql.lib

9) gem install mysql2 -- --with-mysql-dir=c:\tmp\mysql

就是这样! Mysql2 gem 在 Windows 8.1 上的 Rails x64 上运行! =)
