compilation fun with bsc
by lowly coder 18 Mai '09

18 Mai '09

I realize that for blackhole, c-define-type's are not exported across modules. How do I pull them in? The following code does not compile under bsc (but does under gsc) ~/magic$ cat test3.scm (c-define-type yay int) ~/magic$ bsc test3.scm *** ERROR IN "/home/x/magic/test3.scm"@1.20 -- Undefined C type identifier ~/magic$ gsc test3.scm test3.c:35: warning: deprecated conversion from string constant to ‘char*’ test3.c:89: warning: deprecated conversion from string constant to ‘char*’ I grepped bh/modules for examples of how to use c-define-type, but the only one there used (void). Thanks!

Brad, thanks a lot - that's exactly what I was looking for! Best regards.

That's what file and ldd report on gsi compiled on Ubuntu Linux (no static/dynamic related options supplied to configure): file gsi gsi: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.8, dynamically linked (uses shared libs), not stripped ldd gsi linux-gate.so.1 => (0xb7f9e000) libutil.so.1 => /lib/tls/i686/cmov/libutil.so.1 (0xb7f88000) libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb7f84000) libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0xb7f5e000) libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7e0f000) /lib/ld-linux.so.2 (0xb7f9f000) The problem is that such an executable may be incompatible with some another Linux - if it has some older version of libc, for example. I've tried explicit --disable-shared just in case, but it does not make gsi static...

Static GSI
by Kirill Lisovsky 16 Mai '09

Hello, I'd like to compile Gambit interpreter as a static executable. I've done that in the past with Gambit 3, but is it possible to do so with modern Gambit?

a black hole ate up my macros

Marc: I'm using the very latest, greatest gambit.el: frying-pan:~> ll /usr/local/Gambit-C/current/share/emacs/site-lisp/ total 24 -rw-r--r-- 1 root root 23948 2009-05-12 21:17 gambit.el My .emacs file is frying-pan:~> cat .emacs (global-font-lock-mode 0) (custom-set-variables ;; custom-set-variables was added by Custom. ;; If you edit it by hand, you could mess it up, so be careful. ;; Your init file should contain only one such instance. ;; If there is more than one, they won't work right.

And if I don't have the special gambit indentation rules, I shouldn't be editing the gambit sources, should I. This is with GNU Emacs 22.2.1 (GTK+ modified by Ubuntu). Any ideas? Brad

This seems oddly inconsistent with call-with-input-vect and with-input-from-vect, both of which return the results of the execution. In fact, the manual and wiki both list the output variants as returning the values of their procedure or thunk, respectively, so it might be necessary to update the documentation. Brendan MacDonell

I seem unable to grasp I/O...
by Alex Queiroz 12 Mai '09

Hallo, Why does this code always return the output vector, instead of whatever I put inside the inner 'if'? (define (embed-resource file) (let* ((buffer-size 4096) (buffer (make-u8vector buffer-size 0)) (out-vector (make-u8vector 0)) (info (file-info file))) (if (eq? (file-info-type info) 'regular) (call-with-input-file file (lambda (in) (call-with-output-u8vector out-vector (lambda (out) (let loop () (let ((size (read-subu8vector buffer 0 buffer-size in))) (write-subu8vector buffer 0 size out) (if (< size buffer-size) `(define ,(string->symbol (path-strip-extension file))) (loop)))))))) (error "bad file" file)))) Cheers, -- -alex http://www.ventonegro.org/

documentation on the namespace system

what's the best documentation on the namespace system (as of gambit 4.4.2?) in section 7 of the gambit manual, all I see is: TODO :-)
