Win64 compiling package from source: “sorry, unimplemented: 64 bit mode not compiled in”

Question

Trying to install RMySQL on 64-bit Windows 7.

Using R-2.14.2 with Rtools214 and MySQL Server 5.5.

Read through several step-by-steps of RMySQL source installation.

Troubleshooting: - Copied libmysql.dll to R-2.14.2/bin AND R-2.14.2/bin/i386. - Copied libmysql.dll and libmysql.lib to MySQL Server 5.5\lib\opt. - Entered MYSQL_HOME=C:\Program Files\MySQL\MySQL Server 5.5 into Renviron.site, saved to R\R-2.14.2\etc.

My instances of common problems:

Sys.getenv('MySQL_HOME') [1] "C:\Program Files\MySQL\MySQL Server 5.5\"

install.packages('RMySQL', type = 'source') Installing package(s) ... ... RS-DBI.c:1:0: sorry, unimplemented: 64-bit mode not compiled in make: [RS-DBI.o] Error 1* ERROR: compilation failed for package 'RMySQL' ...

I'm guessing my problem lies in the '64-bit mode...' message, but I'm not sure.

Thoughts?

Answer 1

I had problems installing RMySQl so I installed the package RODBC which works fine. (make sure the MySQL driver is installed).

Answer 2

I'm not sure this error message has anything to do with RMySQL, or any particular package.

On 64bit Windows, instead of the default PATH :

C:\Rtools\MinGW\bin

( gives the error sorry, unimplemented: 64-bit mode not compiled in )

you might (quite reasonably) notice the MinGW64 directory alongside and try :

C:\Rtools\MinGW64\bin

but in fact it needs to be :

C:\Rtools\gcc-4.6.3\bin

Then of course, stop and start a new DOS window to pick up the new PATH.
