Errors loading CFFI: BAD-SYSTEM-NAME, missing Maven executable
by Mirko Vukovic 04 Jan '17

Loading CFFI, I get BAD-SYSTEM-NAME errors related to followed by a huge stack dump, and then debugger related to the Maven executable. I tested this with --noinit. Thanks for your help. Here are more details: Starting ABCL on Windows 10 like so: >/c/Windows/SysWOW64/java.exe -jar /c/mv-program-files/abcl-bin-1.4.0/abcl.jar Armed Bear Common Lisp 1.4.0 Java 1.7.0_51 Oracle Corporation Java HotSpot(TM) Client VM Low-level initialization completed in 0.23 seconds. Now I try to load cffi with quicklisp. Following quickload, I get many style-warnings about redefining UIOP: CL-USER(1): (ql:quickload :cffi) To load "cffi": Load 1 ASDF system: cffi ; Loading "cffi" .................................................. .................................................. .................................................. .................................................. .................................... ; Caught STYLE-WARNING: ; redefining UIOP/PACKAGE:FIND-PACKAGE* in #P"C:/mv-program-files/my-lisp-libraries/asdf/uiop/package.lisp" (previously defined in #P"C:/Users/977315/asdf.3.1.7.43.lisp") ; Caught STYLE-WARNING: ; redefining UIOP/PACKAGE:FIND-SYMBOL* in #P"C:/mv-program-files/my-lisp-libraries/asdf/uiop/package.lisp" (previously defined in #P"C:/Users/977315/asdf.3.1.7.43.lisp") .... many such warnings ... After finishing the style-warning messages, come ASDF load messages, the BAD-SYSTEM-NAME messages, followed by a long java stack dump: Using probed value of abcl-contrib: 'C:/mv-program-files/abcl-bin-1.4.0/abcl-contrib.jar'.

ELS'17 - 10th European Lisp Symposium VUB - Vrije Universiteit Brussel Belgium April 3-4, 2017 In co-location with <Programming> 2017 Sponsored by Brunner Software GmbH http://www.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, Hop and so on. We encourage everyone interested in Lisp to participate. The 10th European Lisp Symposium invites high quality papers about novel research results, insights and lessons learned from practical applications and educational perspectives. We also encourage submissions about known ideas as long as they are presented in a new setting and/or in a highly elegant way. Topics include but are not limited to: - Context-, aspect-, domain-oriented and generative programming - Macro-, reflective-, meta- and/or rule-based development approaches - Language design and implementation - Language integration, inter-operation and deployment - Development methodologies, support and environments - Educational approaches and perspectives - Experience reports and case studies We invite submissions in the following forms: Papers: Technical papers of up to 8 pages that describe original results or explain known ideas in new and elegant ways. Demonstrations: Abstracts of up to 2 pages for demonstrations of tools, libraries, and applications. Tutorials: Abstracts of up to 4 pages for in-depth presentations about topics of special interest for at least 90 minutes and up to 180 minutes. The symposium will also provide slots for lightning talks, to be registered on-site every day. All submissions should be formatted following the ACM SIGS guidelines and include ACM classification categories and terms. For more information on the submission guidelines and the ACM keywords, see: http://www.acm.org/sigs/publications/proceedings-templates and http://www.acm.org/about/class/1998. The conference proceedings will be published in the ACM Digital Library. Submissions should be uploaded to Easy Chair, at the following address: https://www.easychair.org/conferences/?conf=els17 Note: to help us with the review process please indicate the type of submission by entering either "paper", "demo", or "tutorial" in the Keywords field. Important dates: - 30 Jan 2017 Submission deadline - 27 Feb 2017 Notification of acceptance - 20 Mar 2017 Final papers due - 03-04 Apr 2017 Symposium Programme chair: Alberto Riva, University of Florida, USA Programme committee: Marco Antoniotti, Università Milano Bicocca, Italy Marc Battyani, FractalConcept Theo D'Hondt, Vrije Universiteit Brussel, Belgium Marc Feeley, Université de Montreal, Canada Stelian Ionescu, Google Rainer Joswig, Independent Consultant, Germany António Menezes Leitão, Technical University of Lisbon, Portugal Nick Levine, RavenPack Henry Lieberman, MIT, USA Mark Tarver, Shen Programming Group Jay McCarthy, University of Massachusetts Lowell, USA Christian Queinnec, Université Pierre et Marie Curie, France François-René Rideau, Bridgewater Associates, USA Nikodemus Siivola, ZenRobotics Ltd Alessio Stalla, Università degli Studi di Genova, Italy Search Keywords: #els2017, ELS 2017, ELS '17, European Lisp Symposium 2017, European Lisp Symposium '17, 10th ELS, 10th European Lisp Symposium, European Lisp Conference 2017, European Lisp Conference '17 -- Resistance is futile.

How to add abcl.jar to your class path for ABCL projects
by Mirko Vukovic 01 Jan '17

Hello, This is a follow-up to my earlier post on stack overflow. That problem is still not solved and here is one question. On the user documentation page I found the instruction to "add abcl.jar to your class path for ABCL projects" How do I do that? Thanks, Mirko

stack overflow error on library load
by Mirko Vukovic 20 Dec '16

20 Dec '16

Hello, I have installed ABCL 1.4 on Windows 10 and Java 1.7. When loading some libraries, I get a stack overflow error. For example loading vecto fails vecto passes the cl-test-grid on linux (see https://common-lisp.net/project/cl-test-grid/library/vecto.html) Running (asdf:load-system :vecto) Gives: Stack overflow. [Condition of type STORAGE-CONDITION] Restarts: 0: [*ABORT] Return to SLIME's top level. 1: [ABORT] Abort thread.

[HEADS UP] Fasl bump needed for working on TRUNK for recording SYS:SOURCE information
by Mark Evenson 24 Nov '16

24 Nov '16

HEADS-UP: the fasl version has been bumped on TRUNK for those of you following along at home. Alan Ruttenberg's [enhancements to record source information][415] have now been merged. [415]: http://abcl.org/trac/ticket/415 The interface to recording information on the SYS:%SOURCE plist for a symbol is now deprecated and will be removed with abcl-1.7. Source information for ABCL is now recorded on the SYS:SOURCE property. The appropiate information for type is recorded by the SYS:RECORD-SOURCE-INFORMATION-BY-TYPE function Now we just have to change SLIME… -- "A screaming comes across the sky. It has happened before, but there is nothing to compare to it now."

Java-9 support
by Mark Evenson 22 Nov '16

22 Nov '16

Curious about what exactly our situation running on Java 9 would be, I took a stab at compiling/running ABCL under: "1.5.0-dev" "Java_HotSpot(TM)_64-Bit_Server_VM-Oracle_Corporation-9-ea+145" "x86_64-Mac_OS_X-10.12.1" The good news is that setting the javac source/target to "1.6" seems to be fine, so the assertion that the compiler will continue to work, albeit inefficiently as noted by Alessio, seems to be born out. The bad news is that due to the changes for "Project Jigsaw" aka [modular-runtime-images][], ABCL can no longer load ABCL-CONTRIB and therefore prevents ASDF from working. The root problem stems from Java 9 no longer using jar archives for system classes, which means that the boot classloader is no longer a descendant of URLClassloader which our current code relies on. Ticket [424][] tracks this issue, containing a patch that at least gets ABCL compiled/running the base ANSI system under Java 9. [423]: http://abcl.org/trac/ticket/423 [modular-runtime-images] https://bugs.openjdk.java.net/browse/JDK-8061971 -- "A screaming comes across the sky. It has happened before, but there is nothing to compare to it now."
