Calling rand_unif() from fortran
What is the necesary incantation to call rand_unif() from a fortran
routine?
Just inserting rand_unif() into the fortran code compiles OK, but won't
dyn.load():

Error in dyn.load(x, as.logical(local), as.logical(now)) :

Detecting compilation under R
...ple, suppose I have some C that uses GSL to get a random
number if its a standalone program, or uses R's internals if its being
compiled to run in R. I want to do something like:
#ifdef USING_R
#include <R.h>
#else
#include <gsl_random.h>
#endif
and then:
#ifdef USING_R
x = rand_unif(0.0,1.0);
#else
x = gsl_runif(0.0,1.0);
#endif
(cant remember the exact names but hopefully you get the idea). This
fails because USING_R is only set when R.h is included.
Are there any preprocessor definitions set by R CMD SHLIB and R CMD
BUILD that I can test against?
Of course I can...
