Thanks! That works.

You don't need easyffi in your example. A call to print out the value
of string-length could be added.

x2.scm
(define-external (foo (c-string x)) int (print (string-length x)))
(return-to-host)
y2.c
#include "chicken.h"
extern int foo(char* blah);
int main()
I've been trying for a while now to get a main C program to get
compiled with a Scheme program and call a Scheme callback. My current
attempt follows; I just modified one of the embedding examples, so I
wouldn't get the embedding part wrong.
x2.scm:
