r mysql追加,将RMySQL程序包添加到R失败（在Windows上）？

I can't figure out why my RMySQL package won't install - here's what I get:

> install.packages('RMySQL',type='source')

trying URL 'http://cran.mirrors.hoobly.com/src/contrib/RMySQL_0.7-5.tar.gz'

Content type 'application/x-gzip' length 160769 bytes (157 Kb)

opened URL

downloaded 157 Kb

* installing *source* package 'RMySQL' ...

ERROR: configuration failed for package 'RMySQL'

* removing 'C:/PROGRA~1/R/R-212~1.0/library/RMySQL'

The downloaded packages are in '(foo)'

Warning message:

In install.packages("RMySQL", type = "source") : installation of package 'RMySQL' had non-zero exit status

I don't think it's a problem with the MySQL install, as the right values seem to be in the registry:

> Sys.getenv('MYSQL_HOME')

MYSQL_HOME "C:/PROGRA~1/MySQL/MYSQLS~1.1/"

> readRegistry("SOFTWARE\MySQL AB", hive="HLM", maxdepth=2)

$`MySQL Server 5.1`

$`MySQL Server 5.1`$DataLocation

[1] "C:\Documents and Settings\All Users\Application Data\MySQL\MySQL Server 5.1\"

$`MySQL Server 5.1`$FoundExistingDataDir

[1] "0"

$`MySQL Server 5.1`$Location

[1] "C:\Program Files\MySQL\MySQL Server 5.1\"

$`MySQL Server 5.1`$Version

[1] "5.1.54"

Puzzled. Any help would be greatly appreciated!

解决方案

The basic process is described here, but there are several hints, So I will describe the whole solution (please change the R version and paths if needed):

Install latest RTools from here

install MySQL or header and library files of mysql

create or edit file C:Program FilesRR-2.12.1etcRenviron.site and add line like MYSQL_HOME=C:/mysql (path to your mysql files)

copy libmysql.lib from mysql/lib to mysql/lib/opt to meet dependencies.

copy libmysql.dll to C:Program FilesRR-2.12.1bin or to windows/system32 directory.

run install.packages('RMySQL',type='source') and wait while compilation will end.

This worked for me on Windows 7 64 bit, so there should be no problems with 32 bit versions
