I already tried the example yesterday because I read it here ([Error: cannot allocate vector of size 17348.7 Gb - #10 by bgoodri](https://discourse.mc-stan.org/t/error-cannot-allocate-vector-of-size-17348-7-gb/14615/10)) but RStudio always freezes and doesn’t react anymore after around 2 minutes.

Those are the outputs:  
`Sys.which("make")`  
` make`  
`"C:\\rtools40\\usr\\bin\\make.exe"`

`Sys.getenv("BINPREF")`  
`""`  
`Sys.getenv("PATH")`

> “C:\rtools40\usr\bin;C:\Program Files\R\R-4.0.0\bin\x64;C:\Rtools\bin;C:\ProgramData\Oracle\Java\javapath;C:\Program Files (x86)\Intel\iCLS Client\;C:\Program Files\Intel\iCLS Client\;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files\IBM\SPSS\Statistics\24\JRE\bin;C:\Program Files\Java\jdk1.8.0\_111\bin;C:\Program Files\apache-maven-3.5.0\bin;C:\WINDOWS\System32\OpenSSH\;C:\Program Files\Sawtooth Software\CBCHB;C:\Program Files\PsychoPy3;C:\Program Files\PsychoPy3\DLLs;C:\Program Files\MATLAB\R2019b\bin;C:\Program Files\SlikSvn\bin;C:\Users\carin\AppData\Local\Microsoft\WindowsApps;”

`readLines("~/.R/Makevars.win")`

> [1] “CXX14=$(BINPREF)g++ -O2 -march=native -mtune=native”  
> [2] “CXX14FLAGS=-O3 -mtune=native -march=native -Wno-unused-variable -Wno-unused-function”  
> [3] “CXX11FLAGS=-O3 -march=native -mtune=native”

I guess the problem is the empty BINPREF. I am sure that I set it manually yesterday but now it’s empty again. Also there seems to be an old PATH variable from previous version of Rtools that I set manually back than to make it work, so maybe that why it wasn’t removed when de-installing them. I tried to figure out how to remove them but my ‘.Rprofil’ file where it should be is empty. So, it seems it’s all not how it should be…
