Funded ISC Grants (2020-2)
As of R 4.0.0 (released April 2020), R for Windows uses a brand new toolchain bundle called rtools40. This version upgrades the mingw-gcc toolchains to version 8.3.0, and introduces a powerful new build system based on the widely used msys2 platform, which makes it easier to maintain R itself, as well as system libraries needed for developing R and R-packages.
The current project seeks to build out this system to improve tooling for building and debugging on Windows, and move towards a scalable build infrastructure, which is transparent, extensible, and fully automated. Thereby we can empower development on Windows, and support further growth of the R ecosystem while relieving work for CRAN and R-core members.
