Apologies for the multiple postings. 

PAPER SUBMISSION DEADLINE EXTENDED 

European Lisp Symposium 2012, Zadar, Croatia, April 30th - May 1st, 2012 

http://european-lisp-symposium.org 

The purpose of the European Lisp Symposium is to provide a forum for 
the discussion and dissemination of all aspects of design, 
implementation and application of any of the Lisp and Lisp-inspired 
dialects, including Common Lisp, Scheme, Emacs Lisp, AutoLisp, ISLISP, 
Dylan, Clojure, ACL2, ECMAScript, Racket, SKILL, and so on. We 
encourage everyone interested in Lisp to participate. 

The main theme of the 2012 European Lisp Conference is 
"Interoperability: Systems, Libraries, Workflows".  Lisp based and 
functional-languages based systems have grown a variety of solutions 
to become more and more integrated with the wider world of Information 
and Communication Technologies in current use.  There are several 
dimensions to the scope of the solutions proposed, ranging from 
"embedding" of interpreters in C-based systems, to the development of 
abstractions levels that facilitate the expression of complex context 
dependent tasks, to the construction of exchange formats handling 
libraries, to the construction of theorem-provers for the "Semantic 
Web".  The European Lisp Symposium 2012 solicits the submission of 
papers with this specific theme in mind, alongside the more 
traditional tracks which have appeared in the past editions. 

We invite submissions in the following forms:

What about following change?  Otherwise on Debian build fails
because etags refuses to overwrite empty file.  It would be
better to fix things so that it actually works, but since
the error is ignorable we may as well ignore it in Makefile.

building maxima

I ran into another file that won't compile with ECL 11.1.1 as I've been 
trying to build maxima. I've attached the file for your inspection 
because after looking it over, I don't see the problem. It looks like 
the compiler is complaining about (CCV 0.0) is not a legal function 
name, when in fact (CCV is a variable with an init-form for 
initialization. I'm still learning to work with common lisp, so I may be 
incorrect here.

The make error I get when trying to build is:
;        - Compiling source file

Hi Juan,

In order to try windows build without installing older gcc, I tried to build it using clang.

It built C code fine, but failed in linking phase.

I opened a bug at https://sourceforge.net/tracker/?func=detail&aid=3482358&group_id=30035&atid=398053

It seems that gcc and clang on windows use different naming convention for exported symbols (leading underscores or not) on windows. I don't have an idea if fixing clang/windows build would be simple enough to take it into the release?

Apparently the problem is LLVM's. It is a bug in their compiler, which does not produce the right link flags for symbols with declspec(dllexport)

See http://permalink.gmane.org/gmane.comp.compilers.llvm.bugs/4614

Can I close the bug report?

Would this work?

touch $ <at>

I did not see this bug in Ubuntu. Maybe it uses a different etags...

FWIW, I can confirm this. The lisp code is valid; I don't know why ecl fails on this. I spent a few seconds trying to come up with a simpler test case, but failed.

Re: Release candidate for ECL 12.2.1

This bug you linked is reported for llvm-gcc, not clang, but I guess they share the same issue.

You can close the bug report.

Thanks,
Marko

This code got mangled in the mail, but AFAICS the change is
to remove 'echo' command at the beginning and add 'touch' at
the end.  Still fails:

etags: Unknown language "none" in "language" option

The problem is that there are too many etags around and their options are different. If someone could sanitize this, then it would be nice but it is a very low priority for me right now.

My apologies. I have tried simplifying ECL's compiler code at several points. One part is the function that deals with all list forms and in particular with those that have more than 63 arguments: the code did not do macroexpansion. I have fixed this and, apart from Maxima's wrong declaration in some f2cl files, it builds fine.

Thanks again for reporting.
