Never mind, I figured it out. The actual problem is I didn't get the correct error message.

Hello guys.

I built myself a with guile-1.8.8 source code. When running, I got the error:
Unbound variable: define-private

According to my debug tracing, the initialization of scm_init_guile has been executed safely. And I'm sure that boot-9.scm has been loaded. The error occurred at a user scm file:

(define-public (randomize-rand-seed)
((t (gettimeofday))
(seed (*
(cdr t)
(car t)
(set! *random-state* (seed->random-state seed))))

I saw that the C function getpid has been called, then the error was thrown.

And I noticed that the define-private was referenced only once in boot-9.scm around all guile-1.8.8 assets:
(define define-private define)

(defmacro define-public args
(define (syntax)
(error "bad syntax" (list 'define-public args)))
(define (defined-name n)
((symbol? n) n)
((pair? n) (defined-name (car n)))
(else (syntax))))
((null? args)
(let ((name (defined-name (car args))))
(define-private ,@args)
(eval-case ((load-toplevel) (export ,name))))))))

I tried to replace 'define-private' by 'define', and I got an error of 'Unbound variable: define'. I'm new in language Scheme and GUILE, I have no idea what happened.

I adjusted some C building config options to adapt the Android NDK build environment. That seems not related to this problem, but I'm not sure. Here is my config.h.

Thanks for any help.
