R include directory is empty

I have RedHat 6.5 (x86_64-redhat-linux-gnu) running R version 3.0.2 (2013-09-25).

As explained in this SO question, some packages install fine, while others produce the warning "R include directory is empty -- perhaps need to install R-devel.rpm or similar". When this warning appears, I also get make: gcc: Command not found and the package fails to compile.

The answer is apparently to install the "development headers", but I am not sure what this means. The accepted answer does not explain it.

I tried sudo yum install R-devel, but I get some errors related to dependencies.

I'm not sure what this means. New to Linux.

Solution

I found that other folks were having trouble with the same dependencies, so I uninstalled RStudio then reinstalled the latest version. To get the newest version of R, I configured yum to use EPEL.

su -c 'rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm'

Then I followed these instructions to re-install R.

su -c 'yum install R R-core R-core-devel R-devel'

This enabled me to install packages that need to be compiled.
