How to Configure R 4.3 on RHEL 8 for Seamless Package Installation

If you're a data scientist or a statistician working with R, you might have encountered issues when trying to install packages on RHEL 8. Recently, a user faced a series of errors while attempting to install the Rcpp package in R 4.3 on their RHEL 8 server. The errors hinted at possible compatibility problems between the version of R and the system's installed compilation tools, mainly gcc, g++, and make.

In this guide, we'll delve into how to configure R 4.3 to run smoothly on RHEL 8, addressing common errors and their solutions.

These errors generally signify that the installed version of R may not be compatible with the current versions of gcc, g++, or make. The user suspected that the default version of gcc (8.5.0) and Make (4.2.1) on their RHEL might be causing these issues.

Investigating the Compatibility

To properly function, R packages require compilation that involves gcc, g++, and make. When these tools' versions deviate from R's requirements, issues arise. The user noticed that other packages, such as haven and xml2, displayed similar errors upon installation attempts.

Recommended Solution: Upgrading R

After researching various forums and potential fixes, the user managed to resolve their issue by upgrading R from version 4.3 to 4.3.2. Here’s why this works:

Compatibility Fix: Often, newer versions of R rectify bugs and enhance compatibility with system libraries and tools. R version 4.3.2 is designed to provide a more suitable environment for package compilation on RHEL 8.

System-wide Configuration: By upgrading R, the user can ensure that all users on their RHEL server benefit from an improved system without needing individual configurations in their ~/.R/Makevars.
