Dear STAN Modellers,

I have the error shown below when I try to “fit” a model (simple 2D GMM).

Could you please give me a hint on how I can fix this ?

Thank you,  
Jozsef

```

If I execute the following code:

It is not finding your StanHeaders package. I would install the latest RStan.

Hi @bgoodri,

Let me check what is going on, and check the RStan installation.

Cheers

So, @bgoodri

I should install the latest RStan from source ?  
You mean this command ?

```
install.packages("rstan", type = "source")

```

from here : [https://github.com/stan-dev/rstan/wiki/Installing-RStan-on-Linux](https://github.com/stan-dev/rstan/wiki/Installing-RStan-on-Linux) ?

Is that what you mean by latest ?

Cheers

Jozsef

Yes, although on Linux `type = "source"` is the default.

Hi @bgoodri,

I got this result :

 ![image](https://canada1.discourse-cdn.com/flex030/uploads/mc_stan/original/2X/6/6d4781dae7de9e5ea57d4aa3baf14456f8752c22.png)  
with the following Makevars :

is there some simple easy one line command that tests that `rstan` was correctly installed  
and can compile and run HMC simulations ? Or do I have to run my own program to do that ?

Or is it possible to write a simple one line Stan code that prints "hello world ?  
EDIT : I found this - perfect !
