Hi stan’s users,

I followed the description about installing rstan on Mac. However I didn’t install anything.  
I got this error below :

> fx ← inline::cxxfunction( signature(x = “integer”, y = “numeric” ),‘return ScalarReal( INTEGER(x)[0] \* REAL(y)[0] ) ;’ )  
> /Library/Frameworks/R.framework/Resources/bin/Rcmd: line 38: sed: command not found  
> sh: make: command not found

Could you help me how to do for that, please ?

Kind regards.

What is the output of `system("gcc --version")` ?

It helps if you’re more explicit about what you did. Did you install Xcode and the command line tools?

Hi,  
Yes, in fact I noticed I had download xcode beta. But after download xcode from itunes, everything works now.

Thank for you help.
