[C2hs] No automatic support for marshaling of structures?

[zhu Jun]

Hi All,

When I was trying to marshal a C structure in Haskell, I met such error:
"Illegal structure or union type! There is no automatic support for
marshaling of structures and unions". However, if I try to marshal the
pointer to a structure, it works well.
Could anyone give me any hints? Thank you!

The structure I define in C is:
-------------
typedef point{
 int x,y;
};
--------------
And the marshaling code in C2HS is:
--------------
newtype Point = Point {#type point#}
--------------

Best wishes,
  Jun
