UNIX error 14 (EFAULT)

Hi all,

I would like to ask if there is a way to avoid the following crash:

1) In the first terminal run

   $ tcpserver 127.0.0.1 3333 clisp -norc -q -x '(print :hi)'

2) In the second terminal run

   $ nc localhost 3333 

   :HI 
   :HI
   $

3) In the first terminal I get

   *** - UNIX error 14 (EFAULT): Bad address

   [/build/buildd/clisp-2.49/src/eval.d:573] reset() found no driver frame
   (sp=0x7fff36a66930-0x7fff36a612f0)

which doesn't seem right, there seems to be an issue with closing the
pipe.

I am running the default clisp which comes with the latest ubuntu GNU
CLISP 2.49 (2010-07-07) on machine with Linux 3.2.0-24-generic
#37-Ubuntu SMP x86_64 GNU/Linux.

stream-handles behavior


  Hello,

The current behavior of EXT:STREAM-HANDLES is to return two file
descriptors (input and output) when possible, and error otherwise.

The problem I have with this behavior is that (apparently) there's no
way to predict whether it is possible to perform this operation or not
on a random stream (notably when it's just of class STREAM): IIUC,
stream_handles does the validity check based on information which is
only available at the C level.

I can currently work around this by catching STREAM-SIMPLE-ERROR but
this is not satisfactory (too coarse a grain). So my question is:

- would it hurt if EXT:STREAM-HANDLES were changed to return nil instead
  of error'ing? CCL does this with his STREAM-DEVICE function for
  instance.

- otherwise, could we have a predicate such as STREAM-HAS-HANDLES-P
  please?

Or, we could enrich the STREAM class hierarchy with a mixin for streams
with handles, or, expose the current implementation details (the
strmtype field) to the Lisp level. But maybe we don't want to go that
far 

Thanks!

advice sought - debugging core files


I see some core files sitting around.
The file command shows, e.g.,
/home/jack/data2012/core.29192: ELF 32-bit LSB core file Intel 80386,
version 1 (SYSV), SVR4-style, from '/usr/lib/clisp-2.49/base/lisp.run -B
/usr/lib/clisp-2.49 -M /usr/lib/clisp-2.49' 

Is there some way to use the lisp debugger to see what was going on?

So far I'm up to here:

$ gdb /usr/lib/clisp-2.49/base/lisp.run /home/jack/data2012/core.29192

clisp, regexp:match, and subgroups?

I'm trying to understand (regexp:match...).  I have this function
where it is matching a pattern.  I'm trying to extract that pattern.
I found where the POSIX regexps will match subgroups.  Great. I have the
matching working.  Now, how do I see any subgroup other than the first
one?  I found a mention of a (multi-value-bind...), but clisp says that
function doesn't exist.  How do I access the other-than-first matches?

"full" does not "make install"

On Linux, I downloaded all the components source code and was able to "make install" them.

The base is installed, but the "full" directory does not get installed.
I succeeded by manually creating the directory, links, and copying the files.

status of clisp on OS X

I am trying to set up clisp for FastCGI on the Mac (Snow Leopard), and it's not going well.

I downloaded libsigsegv-2.9 and it will build, but doesn't work: stackoverflow2 fails.
The MacPorts libsigsegv-2.9.0 builds and installs (don't know if it runs the checks, though).

The ffcall-1.10 doesn't even configure without blowing up several times,
and once you get past that, it doesn't build (either from the downloaded version or from MacPorts).
I see that this was originally reported a little over a year ago and the answer was:
MacOS on Intel is not supported.

I was trying to avoid being stuck on an old release, but I wanted to use clisp, not debug it.
So at this point, I gave up and tried "port install clisp".

Error: Target org.macports.build returned: shell command failed (see log for details)
Error: Status 1 encountered during processing.

clisp with LAPACK floating-point underflow

Looking for hints from anyone using LAPACK with clisp (2.48).  I've built the
clocc software, and build and loaded f2cl, then compiled and loaded LAPACK. 
When I call an LAPACK function, say by calling (test-dgeev) in the
lapack-tests.lisp file, there is a floating-point underflow or divide by zero
failure.  But it is not the input data.  I have a build of maxima built on top
of clisp (2.41), and calling the same function with the same data (within the
to_lisp() environment) is successful.  Evidently, there is a step needed in the
f2cl usage which the maxima developers have figured out.

Link error clisp-2.49 on MacOSX

Hi,

I am trying to compile clisp-2.49 on MacOSX 10.6.8 
and I get an error during link that libiconv is not defined.
(See snippet of the build log below).

I briefly looked at the error and it seems that 
stream.c uses a macro to define iconv --> libiconv and libiconv is not
in the libiconv.2.4.0.dylib.

Does anyone have some tips on how to fix this or debug this further.
(I hope it is just a configure time flag.)

fastcgi doesn't apper in FEATURES

I built clisp on a ubuntu server with './confiugre --with-module=fastcgi',
and everything got ok when I run 'make' and 'make install'.

But then when I entered the clisp repl and checked *FEATURES*, it didn't
include ':FASTCGI' or any similar symbols.

What it the problem and how can I fix it?

Thanks.

Re: connecting CLISP and Java

Hi Kaz,

I've tried to compile my lisp application using ABCL but a appears a lot of errors, because it has some 
implementation-specific extensions that doesn’t work with ABCL that's why I stopped using.

The only two implementations that works fine with my lisp application are Allegro CL and CLISP (http://www.clisp.org/)

Any Ideas how to communicate CLISP with Java?

Thanks
