Hi  
I am new to MatlabStan and trying to setup cmdstan following the instructions in cmdstan-guide.pdf given in [https://github.com/stan-dev/cmdstan/releases](https://github.com/stan-dev/cmdstan/releases). Following Section 2.2, Step 2 , I do not see a “local” file in the “make” folder and \cmdstan\make build gets the following error:  
“build” is not recognized as an internal or external command, operable program or batch file.

Operating System: Windows 10  
Interface Version: cmdstan 2.18.0  
Compiler/Toolkit: Rtools 3.4

Please help.

You need to create the `local` file if needed.

Build with `make build` is failing?

You aren’t supposed to run the command “\cmdstan\make build”. You’re supposed to go into the “\cmdstan” directory and run the command “make build”.

Well, `build` is an option indexed in the `makefile`.

My makefile contains the following

```
build: $(LIBMPI) bin/stanc$(EXE) bin/stansummary$(EXE) bin/print$(EXE) bin/diagnose$(EXE) $(LIBSUNDIALS)
	@echo ''
	@echo '--- CmdStan v$(CMDSTAN_VERSION) built ---'

```

Thanks @increasechief and @jjramsey and @ahartikainen .

When I went to “\cmdstan” directory and ran the command “make build”, I get the following error:

```

What does this mean?

DId you check Appendix B of the guide? It would seem there that Windows 10 is not official supported. Not that that is the problem per se. From the output of the error message there is a problem cross-compiling to your computers architecture using the build tools available.

Appendix B.3 may be helpful, can you post `g++ -v` and `make -v` as outlined in that section?

The guide recommends using Cygwin, I’ve found Strawberry Perl is more user friendly on install but I haven’t tried using CmdStan in that environment.

Here is what worked for me recently

It looks like you are behind in your `make` version

This would satisfy those requirements: [http://strawberryperl.com/release-notes/5.28.0.1-64bit.html](http://strawberryperl.com/release-notes/5.28.0.1-64bit.html)

It means that you are probably using the 32-bit version of the compiler. What’s the contents of your `PATH` variable?
