Install RMySQL to use with InfiniDB (without installing mysql completely) - r

Question

I've successfully installed InifiniDB on CENTOS 6.5.
InfiniDB is a columnar DB "compatible" with MySQL (same port etc.: I've even managed to install the latest version of MySQLWorkbench and works has a charm with InifiniDB - believing to deal with just another install of MySQL).
The installation does not have MySQL as I don't need it :)
I tried to install RMySQL from RStudio Server, but I am unable to install: the installation expect to find a copy of MySQL somewhere and I do not have it.
See below the installation log. I put :/usr/local/Calpont/mysql/bin in my PATH, but this didn't have any effect.
Please consider that the inspiration for this comes from InfiniDB itself: see here http://infinidb.co/system/files/Calpont%20InfiniDB_Quick%20Start_for%20R.pdf
I guess the main problem, comparing the error and the InfiniDB paper, is that they suggest to create the following global variables:
(From InfiniDB paper) RMySQL must be configured with the correct MySQL directory
(which comes with InfiniDB) and the developer library directory.
o Example in Ubuntu or CentOS:
export MYSQL_INC=”/usr/include/mysql/”
export MYSQL_LIB=”/usr/local/Calpont/mysql/lib/mysql”
But my installation on CENTOS does not have a mysql folder at /usr/include/mysql/.
Any suggestions?

Configuration error:
could not find the MySQL installation include and/or library
directories. Manually specify the location of the MySQL
libraries and the header files and re-run R CMD INSTALL.
INSTRUCTIONS:
1. Define and export the 2 shell variables PKG_CPPFLAGS and
PKG_LIBS to include the directory for header files (*.h)
and libraries, for example (using Bourne shell syntax):
export PKG_CPPFLAGS="-I<MySQL-include-dir>"
export PKG_LIBS="-L<MySQL-lib-dir> -lmysqlclient"
Re-run the R INSTALL command:
R CMD INSTALL RMySQL_<version>.tar.gz
2. Alternatively, you may pass the configure arguments
--with-mysql-dir=<base-dir> (distribution directory)
or
--with-mysql-inc=<base-inc> (where MySQL header files reside)
--with-mysql-lib=<base-lib> (where MySQL libraries reside)
in the call to R INSTALL --configure-args='...'
R CMD INSTALL --configure-args='--with-mysql-dir=DIR' RMySQL_<version>.tar.gz

Answer 1

You do need to install mysql-devel. Please see step 3 of QuickStart Guide for R on InfiniDB website. It states the following:
Install a MySQL developer library on the client machine. Available from http://www.mysql.com and http://dev.mysql.com or you can use a package installer like apt-get. If you already installed a MySQL server, make sure that client header and library files are included in the install.
Example in Ubuntu:
sudo apt-get install mysql-client libmysqlclient-dev
Example in CentOS
sudo yum install mysql mysql-devel
If you have further questions please feel free to post in the InfiniDB forum as well.

Answer 2

I found a solution of sort.
First of all, my premise was to be able to use RMySQL with InfiniDB without adding a MySQL installation to the mix.
(As per wikipedia) "InfiniDB is accessed through a MySQL interface".
A recent paper on InfiniDB website on R and InifiniDB ("R Statistical Computing Quick Start Guide") listed simple instructions to install and use InfiniDB in R with RMySQL without mentioning any pre-requisite.
I found this to be incorrect. Within my CENTOS installation I wasn't able to compile the RMySQL package. The missing mysql.h was preventing it.
The solution I found was to install mysql-devel with yum. Yum installed also mysql client programs and shared libraries as a dependency.
On the other hand the total install with yum was 3MB and I can still say I didn't need MySQL server installed (at least!) as RMySQL+InfiniDB need just the MySQL libraries to work.
