It looks like you didn't initialize Guile anywhere.  Try this:

    #include <stdio.h>
    #include <libguile.h>

    void
    inner_main (void *data, int argc, char **argv)
    {
      char *str;
      size_t len;
      SCM scmVal = scm_int2num (7);
      SCM s_str = scm_object_to_string(scmVal, SCM_UNDEFINED);
      len = SCM_STRING_LENGTH(s_str);
      str = (char *)malloc(len + 1);
      if (!str) abort();
      memcpy(str, SCM_STRING_CHARS(s_str), len);
      str[len] = '\0';

      printf ("%s\n", str);
    }

    int
    main (int argc, char **argv)
    {
      scm_boot_guile (argc, argv, inner_main, NULL);
      return 0;
    }
