Updating nvimcom errors when using Neovim on Windows Cygwin64

[gwd999]

Anyone here has some experience with Nvim-R "updating"

When opening a .R file in Neovim v0.5.1 it shows the message "Updaring nvimcom" and ends it with message "Failed to install nvimcom"

My Sys info:

WINDOWS 10 Pro R-4.0.5 (non standard path) Rtools40 (default path) R_LIB (non standard path)

The package installation messages look like: this:

 * installing to library 'D:/R_LIB/4.0'
 * installing *source* package 'nvimcom' ...
 ** using staged installation
 ** libs
 "C:/rtools40/mingw64/bin/"gcc  -I"C:/R/R-4.0.5/include" -DNDEBUG       -D`C:/R/R-4.0.5/bin/R --slave -e 'cat(Sys.info()[[1]])'` -DLWS_NO_FORK  -DWIN32   -O2 -Wall  -std=gnu99 -mfpmath=sse -msse2 -mstackrealign -c nvimcom.c -o nvimcom.o

ERROR: compilation failed for package 'nvimcom'

Thanks in advance for any advice from someone with experience on that topic? PS: maybe it would be helpful if the neovim pkg would be available again from somewhere to building and install in R independently?

The nvimcom package cannot be on CRAN. Even if it could, there would be a version mismatch whenever a new version was needed and you had only updated either your Vim plugins or your R libraries.

Failure to build nvimcom on Windows is a recurrent problem. I have never managed to fix the issue properly. A pull request fixing the issue is welcome.

Will give it a shot - not really sure I will manage ...
