Problem compiling Stan code

Hi,

I’ve recently upgraded my MacOS, and consequently some other software too - such as the xtools command line compiler stuff.

I am now having problems with RStan (I have previously had a functioning installation), although since I am not currently a daily user of RStan I cannot state that the problem followed the OS upgrades.

I have tried uninstalling RStan and reinstalling as per the github getting started page, having read about similar issues on this forum. And simplified my .R/Makevars file.

But when I run stan.mod <- stan_model('p1_p2_o.stan'), I am getting:

Error in compileCode(f, code, language = language, verbose = verbose) :
  Compilation ERROR, function(s)/method(s) not created! In file included from filef6bf407f62b.cpp:8:

In addition: Warning message:

Error in sink(type = "output") : invalid connection

Any suggestions welcomed.

The standard information follows…

Operating system: MacOS 10.14.1 (Mojave)

RStan version: 2.18.2

Cancel that.

I changed the /usr/local/clang4/bin/clang and /usr/local/clang4/bin/clang++ references in .R/Makevars to /usr/bin/clang and /usr/bin/clang++ and that seems to be good now.

I dropped the LDFLAGS=-L/usr/local/clang4/lib too, which seems sensible if I’m not using that version of clang.
