Cant install cmdstan: g++ comand not found

Question

I'm tyrying to install CmdStan on Win 11. That I've done:

1. Install the C++ toolchain using RTools 4.3
2. Adding RTools43 bin paths to the PATH environment variable
3. Building mingw32-make using pacman -Sy mingw-w64-x86_64-make as suggested in this thread.
4. git clone https://github.com/stan-dev/cmdstan.git --recursive
5. cd cmdstan

And there's I got problem: Use mingw32-make build.

I get error:

expr: syntax error: unexpected argument 'line' /usr/bin/sh: line 1:
g++: command not found make/program:19: *** target pattern contains no '%'. Stop.

Answer 1

I've checked my PATH's. And found that my path lead to emtry folder. I found folder with exe-files, that I need and correct PATHs. My prevision path contain only mingw32-make.exe: C:\rtools43\mingw64\bin New path contains all exe's: C:\rtools43\ucrt64\bin
