How to enable quadprog package in PLR

Environment

Product Version
Pivotal Greenplum (GPDB) All versions
OS:Red Hat Enterprise Linux (RHEL)   
 2.14.0
quadprog  1.5-4

Purpose

This article will explain how to enable quadprog package in PLR. 

Procedure 

1. Download the quadprog package source from this link.

The current latest version is 1.5-4 and it depends on R (>=2.12.0). So choose the suitable quadprog version according to R version that is already installed correctly. If you have not installed PLR before, refer to solution 15243.

For example, the quadprog package source is unzipped in the following directory:

[root@mdw quadprog]# pwd
/root/quadprog

2. Install the quadprog source package into R.

[root@mdw ~]# cd /root
[root@mdw ~]# R CMD INSTALL quadprog_1.5-4.tar.gz
* installing to library /usr/local/lib64/R/library
* installing *source* package quadprog...
** libs
gfortran  -fvisibility=hidden -fPIC  -g -O2 -c aind.f -o aind.o
gcc -std=gnu99 -I/usr/local/lib64/R/include  -I/usr/local/include    -fPIC  -g -O2 -fPIC -c init.c -o init.o
gfortran -fvisibility=hidden -fPIC -g -O2 -ffloat-store   -c -o solve.QP.compact.o solve.QP.compact.f
gfortran -fvisibility=hidden -fPIC -g -O2 -ffloat-store   -c -o solve.QP.o solve.QP.f
gfortran  -fvisibility=hidden -fPIC  -g -O2 -c util.f -o util.o
gcc -std=gnu99 -shared -L/usr/local/lib64 -o quadprog.so aind.o init.o solve.QP.compact.o solve.QP.o util.o -L/usr/local/lib64/R/lib -lRblas -lgfortran -lm -lgfortran -lm -L/usr/local/lib64/R/lib -lR
installing to /usr/local/lib64/R/library/quadprog/libs
** R
** preparing package for lazy loading
** help

** building package indices ...
** testing if installed package can be loaded

* DONE (quadprog)

3. Test quadprog in R to confirm that it works.

 4. Test the PLR function in the GPDB.
