Re: Very strange problem loading cmp.fsl

The error below has been hopefully solved. It was made of two problems:

1) When *read-suppress* was not nil, the package of a symbol might not
be ignored.

2) When loading a binary file, ECL creates a list of packages that
appear in interned constants and waits for the program to create them.
This list should be emptied after loading that file, but it was not
always so.

Both problems combined in the bug report that Dan sent. Sorry for the
big delay -- it was not easy to find out the real problem.

Re: trouble with si:load-foreign-module

I am sorry for the delay on solving this problem. I have just found
out that there was no lisp builtin type associated to the dynamically
loaded libraries. I mean that there was a data structure, but it had
no name that was known to functions like class-of, type-of, etc.

This is fixed in CVS now.

Re: C compiler errors during compile-file

The piece of code below failed to be compiled by ECL because of a
missing C declaration in the output file. Fixed in CVS.

Juanjo

(defvar *ls* nil)

(let ((*ls* '(1 2 3 4 5 6 7)))
 (let ((the-list (cons nil *ls*)))
   (let ((prev the-list))
     (flet ((cut () (let (kill)
              (setf kill (cdr prev)
                    (cdr prev) (cdr kill)
                    prev (cons nil prev)))))
       (cut)
     (format t "~S" the-list)))))

CL-ncurses

Has anyone used this with ECL? I need some basic terminal functionality
like user selectable menus. Tried loading cl-ncurses it and got a bunch 
of errors, and there's nothing in the mail archives..

TIA

Re: CL-ncurses

Hi Martin,

I just made some changes to ECL right now, solving some problems such
as a missing DEF-CONSTANT macro from the UFFI package. This and the
patch to cl-ncurses which I attach are enough to compile and load
cl-ncurses using ECL, but I did not try whether it works at all.

building on OpenBSD again..

Am having problems building on OpenBSD right now with the following 
build script (and have tried building both with included and system
boehm-gc and gmp). I do have a working ECL from August 1st so 
something has changed since then affecting the build.

#!/bin/ksh
CFLAGS="-I/usr/local/include/ -I/usr/local/include/gc/"
LDFLAGS="-L/usr/local/lib/"
export CFLAGS LDFLAGS
./configure --enable-boehm=system --prefix=/usr/local/

Switching to directory `build' to continue configuration.

experimental patch for review (unboxed functions and some misc socket fixes)

Hello,

Yesterday I thought that I'd have another go and unboxed functions.
This is the result. It seems a lot cleaner than before, and seems to
work nicely.

There is one big issue, which is how to deal with boxed and unboxed
versions of the same function.

In this patch, I'm using a rather ugly hack to bind the boxed version
as an anonymous function directly to the symbol-function of the name,
and ignoring (setf ...) functions -- this is not a viable approach,
but it should be sufficient to test and verify the meat of the
compiler changes.

I think that it would probably be better to have the boxed version as
the primary function, and to use a property to refer direct calls to a
different function. This would also allow the unboxed interface to
have a specific C name.

When I produced this cvs diff I also noticed two other changes that I
had forgotten about, but they're small, so I've left them in.

When using sockets, I found that short reads weren't being handled
properly -- also the built-in socket server code was leaking
descriptors.

Regards,
Brian.

Problems with clines

Hi,

Can someone tell me what is wrong with the following:

  (defpackage "select-test"
    (:use "CL" "FFI"))
    (in-package "select-test")

  (clines "#include <sys/select.h>")

  (defun test-fun ()
    (clines "fd_set read_fds, write_fds;"
            "FD_ZERO(&read_fds);"
            "FD_ZERO(&write_fds);")
    ;; ....
    ;; Some other code resulting in an fd, but we'll use stdin here
    ;; ....
    (c-inline (fd) (:int) :void 
              "FD_SET(#0, &read_fds);"
              :one-liner nil
              :side-effects t))

Compiling this fails with errors, as all the 'clines' code is placed
into the header rather than inline.  Is this deliberate?

Converting the clines to c-inline fixes this issue but raises another
one; the resulting C source ends up like:

    static cl_object L1test_fun()
    { VT2 VLEX2 CLSR2

Re: experimental patch for review (unboxed functions and some misc socket fixes)

Hi Brian,

thanks for the patch. I will review in the coming days, though I
cannot promise how long it will take until I incorporate the patches.

Yes, that is more reasonable.

Can you be more specific about this? Is this related to the sb-sockets code?
