Re: A weird problem about "define-private', need help please!

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

Hello guys.

I built myself a libguile.so 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)

(ly:randomize-rand-seed)

(let*

((t (gettimeofday))

(seed (*

(cdr t)

(car t)

(getpid))))

(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)

(cond

((symbol? n) n)

((pair? n) (defined-name (car n)))

(else (syntax))))

(cond

((null? args)

(syntax))

(#t

(let ((name (defined-name (car args))))

`(begin

(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.
