adding RMySQL package to R fails (on Windows)?

Question

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.mir         


        

Answer 1

You however there is one additional requirement at present (with the MySQL server version 5.5 & R2.12.1) follow thehttp://biostat.mc.vanderbilt.edu/wiki/Main/RMySQL instructions at present as the locations of the libmySQL.dll differs to what is expected in the package.

i.e. for the 64bit compiling. it expects the libmySQL.dll to be in "${MYSQL_HOME}"/bin/libmySQL.dll so simply copy the dll over to the /bin dir and it will now compile.

for the 32bit compilling. the libmySQL.lib is expected in "${MYSQL_HOME}"/lib/opt/libmysql.lib again moving this should solve the problem.

Alternatively, if you don't want to or can't move these files. Then you can edit the source code files: Makevars.win Makevars.win32 Makevars.win64 appropriately pointing to /lib/libmysql.dll /lib/libmysql.lib
