Rtools 3.5

Windows Toolchain and Build Utilities for R

This repository contains the source files for building the Rtools installer. Official releases can be downloaded from the Rtools homepage on CRAN. The original collection was put together by Prof. Brian Ripley and Duncan Murdoch; it is currently maintained by Jeroen Ooms.

The same Rtools bundle is used both for building R itself as well as compiling R packages from source. Most users only need the latter, so the standard installation type will install:

• 32 and 64 bit mingw-w64 toolchains based on gcc 4.9.3
• Build utilities: make, bash, tar, etc

In addition, Rtools has optional extras for building R itself:

• TexInfo5 for building manuals
• A copy of libicu55 static libs
• TclTK 8.6 required for building the base R package tcltk

For more information about building R itself see the rwinlib/base repository.

Build Rtools

The Rtools installer can be built from rtools.iss using InnoSetup. Either use the GUI or build from the command line:

"C:\Program Files (x86)\Inno Setup 5\iscc.exe" rtools.iss

All of this is automated on AppVeyor.
