【问题描述】：
我逐步制定了所有这些食谱。多次检查是否满足每个条件：
我的设置：
Windows XP 32 位
具有所有必要库和包含文件的 MySQL 5.5 服务器/客户端
路径：C:\Program Files\R\R-2.12.2\bin\i386； C:\WINDOWS\system32 ; C:\WINDOWS ; C:\Progra~1\R\R-212~1.2\bin ; C:\Rtools\bin ; C:\Rtools\MinGW\bin
我仍然无法使用 R 开始编译。RStudio 给了我：
> install.packages('RMySQL', type ='source')
Installing package(s) into ‘C:/Documents and Settings/.../My Documents/R/win-library/2.12’
(as ‘lib’ is unspecified)
trying URL 'http://ftp5.gwdg.de/pub/misc/cran/src/contrib/RMySQL_0.9-3.tar.gz'
Content type 'application/x-gzip' length 165363 bytes (161 Kb)
opened URL
downloaded 161 Kb
>Warning in install.packages :
installation of package 'RMySQL' had non-zero exit status
>The downloaded packages are in
‘C:\Documents and Settings\...\Local Settings\Temp\RtmpZnaoz4\downloaded_packages’
R CMD 正在启动编译，但突然失败。我必须在默认的 Windows 路径中添加 C:\Rtools\MinGW\bin 的路径，以便 R CMD 访问 gcc，尽管在上述任何食谱中都没有提到它。我怀疑路径有问题。也许 R 没有访问 Rtools 或 gcc 或 Rcmd、MySQL 或其他东西......

是否有正当理由使用过时版本的 R 执行此操作？我刚刚检查过，您的 RMySQL 版本是最新的，可能与 R 2.12 存在的版本不同。
