Created attachment 70461 [details] Log when running your script
With the 'same' you mean the same error messages or were you able to install the Catboost package successfully?
I mean, even on windows it doesn't install properly. Wine behaves the same.
So you get the exact same screen output as under Wine? That's interesting since I was able to do so (see screen output in my first message).
I still have no idea why or how you use Cygwin. Cygwin is to run Linux programs on Windows. What does that have to do with R?
Neither do I, but I installed it later in an attempt to avoid that warning message and -possibly- avoid this installation problem. Unfortunately it didn't
So, I download https://mirror.lyrahosting.com/CRAN/bin/windows/base/old/4.0.5/R-4.0.5-win. exe Then I followed your instructions from Comment 2.
See what I got in the attachment. No idea what you're doing, but it's clearly something different.
Ah, I see the message "WARNING: Rtools is required to build R packages, but is not currently installed." My apologize, I've installed the 'devtools' package a long time ago and forgot that it requires that it needs Rtools when you want to install packages from source. Please visit https://cran.r-project.org/bin/windows/Rtools/ and install rtools40v2-x86_64.exe
