Hi, I'm making a trying to bind a gsl library http://www.gnu.org/software/gsl/ so far it was working but when i started binding complex numbers some functions won't work, like trigonometric functions - called they return null.

in gsl code complex struct looks like:

typedef struct
  {
    double dat[2];
  }
gsl_complex;


my complex struct looks like that:

struct _gsl_complex {
  double dat[2];
}
alias gsl_complex = _gsl_complex*;

So, what im doing wrong?

I believe if you're interfacing with C you should use __gshared:

alias gsl_complex = __gshared _gsl_complex*;
