While trying to bind some old C code to ruby I ran into trouble
converting strings. The function in question requires two string
arguments (const char*). This is the relevant part of my binding:
static VALUE rb_ldist(VALUE s, VALUE t)
Compilation works without warnings, but when I try to use the function
in ruby with
it gives me
can’t convert Object into String (TypeError)
Why is it an Object and not a String?
I also tried to use RSTRING(s)->ptr insead of StringValuePtr, but that
gave me an invalid pointer.
Any suggestions on what to do here?
thanks in advance for any help.
