Rtools Issues

Summary:

Trying to download Rtools so I can use rstan, and I need help troubleshooting.

Description:

Hello,

I'm trying to get Rtools34.exe to play nice with Rstudio 1.1.423 on a Windows 10, and I'm not succeeding.

According to the instructions on https://github.com/stan-dev/rstan/wiki/Install-Rtools-for-Windows, I'm supposed to check a box when I get to the "Select Additional Tasks" prompt. However, I don't have the same options as the one depicted in the help page. My choices under "Edit Path" are "Current value: PATH = ... " or "Save version information to registry". If I click on the former, then I have the option to edit the path, and the default path is:

c:\Rtools\bin;
c:\Rtools\mingw_32\bin;
%SystemRoot%\system32;
%SystemRoot%;
%SystemRoot%\System32\Wbem;
%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\

Since I don't have a lot of experience with this, I left it as it was.

In Rstudio, I entered Sys.getenv('Path') and my output is:
[1] "C:\Rtools\bin;C:\Program Files\R\R-3.4.3\bin\x64;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Users\tthalhuber\AppData\Local\Microsoft\WindowsApps;"

I then tried system('g++ -v') and I get:
Warning message:
running command 'g++ -v' had status 127

From what I've seen from other posts, it looks like my path is having a hard time finding the C++ compiler. I'm not sure where to go from here, so I was wondering if anyone had suggestions.

Thanks

The issue mentions Rtools34.exe, RStudio 1.1.423, Windows 10, and the R commands Sys.getenv('Path') and system('g++ -v'), but no repository file or test. Start by reviewing the linked Rtools installation instructions; done would require a resolved compiler setup, not a clearly scoped repository change.
