How to install a source package with c++ code in R windows?

I have an R package with Rcpp code. Builds fine in any linux distribution. The problem is building it in windows. I have the following in my set-up

  1. R version 4.0.1 (2020-06-06)
  2. Windows 10 Pro version 1903
  3. Rtools 4.0 installed in C:\rtools40

This is the output of Rgui:

Solution

  • I found my luck in devtools. I uploaded my package in github and installed using devtools::install_github("myuser/my_rcpp_package"). Using devtools, an R package with c++ code can be built without any issues.
