(rationalize) works differently in ABCL
by Andrew Sengul 27 Nov '21

27 Nov '21

I've been doing operations that require me to rationalize floats, and I've found that (rationalize 2.3d0)gives very different output in ABCL compared SBCL and CCL. Floats can have any number of valid rational conversions but I'd expect a good algorithm for this conversion to find 23/10 rather than the huge numerators and denominators that get produced. It appears that the (rationalize) in ABCL is using the same algorithm as (rational) does in other CLs. Does (rationalize) just pass through to (rational) in ABCL? Would it make sense for ABCL to adopt the implementation of this function used by other CLs? Thanks. Andrew

One more question - compiling large code
by Andrew Sengul 23 Nov '21

23 Nov '21

I was just trying to compile a system containing macros that generate a large amount of code. I got this error: Compiled function can't be loaded: org.armedbear.lisp.demo_tmpHVF0FTR3_246 from org.armedbear.lisp.Pathname@2a31c2ec Does anyone know the likely reason for this? The code I'm compiling works with all other CL implementations I've tried. Is it just a matter of the code size? Thanks, Andrew

Problem - can't set environment variables when starting ABCL via Slime
by Andrew Sengul 21 Nov '21

21 Nov '21

Hello, I'm using ABCL through Emacs with Slime and I'm having trouble setting bash environment variables needed for Maven to work. Here's what I have in my ~/.emacs file: (setq slime-lisp-implementations '((abcl ("/usr/bin/java" "-jar" "/path/to/abcl-bin-1.8.0/abcl.jar" "/path/to/abcl-bin-1.8.0/abcl-contrib.jar" "-Xmx6g") :coding-system utf-8-unix :env ("JAVA_HOME=/path/to/jdk-12/" "PATH=/opt/apache-maven-3.8.3/bin:$PATH")))) Problem is, the $JAVA_HOME and $PATH variables are not set for the ABCL process despite putting them here. The environment variables do work with other CL implementations. When I set them in SBCL, for example, I can run (uiop:run-program "echo $PATH" ...) and see the extension added to the path. This doesn't work in ABCL, and I need those extra environment variables set in order for Maven to work. Does anyone know a way to fix this? It works for other CLs, so I'm guessing something particular about ABCL is preventing the variables from being set. Thanks, Andrew

Error building 'babel' on ABCL 1.8.0 on Windows 10
by mortemeur 16 Sep '21

16 Sep '21

First of all, I assume this is my fault, but I do not know what I screwed up. I am sure I am accidentally leaving out important information, but if you ask me for it I would be happy to include it in a reply. I am trying to learn about Common Lisp and decided to use ABCL on Windows 10, I ran into this error while going through Xach's tutorial ( https://xach.livejournal.com/278047.html). Specifically, I ran: (quickproject:make-project "~/src/lisp/swatchblade/" :depends-on '(vecto hunchentoot)) The error I received is: Error while trying to load definition for system jna from pathname jar:file:///C:/abcl/abcl-contrib.jar!/mvn/jna.asd: Java exception 'java.lang.reflect.InaccessibleObjectException: Unable to make public java.lang.String java.util.jar.JarFile$JarFileEntry.getName() accessible: module java.base does not "opens java.util.jar" to unnamed module @6baeb178'.

Issue running minimal example with jss: module java.base does not "opens java.util.jar" to unnamed module
by Phil Eaton 03 Aug '21

03 Aug '21

Hey folks, I've got a minimal program I'm trying to run: (require 'abcl-contrib) (require 'jss) (setf jss:*muffle-warnings* nil) (add-to-classpath #P"~/.m2/repository/io/javalin/javalin/3.13.10/") (jss:jar-import "javalin-3.13.10.jar") (let* ((port 8080) (app (#"start" (#"create" 'Javalin) port))) (begin (#"get" app (lambda (ctx) (#"result" ctx "Hello World"))))) When I run it: abcl --batch --noinform --load main.lisp I get the following exception when requiring jss I think. jssASDF could not load because Java exception 'java.lang.reflect.InaccessibleObjectException: Unable to make public java.lang.String java.util.jar .JarFile$JarFileEntry.getName() accessible: module java.base does not "opens java.util.jar" to unnamed module @1ece4432'..

Any suggestions for getting this (require :jss) working? Thank you! Phil

Please consider upgrading the version you are distributing with your implementation. Note that this is strictly a bug fix release so should not cause issues in upgrading. But "should" -- software is unpredictable. Announcement email follows. Best, R

Hello, can anyone provide an example of using jnew-runtime-class? Here's the definition I found in the documentation: (CLASS-NAME &REST ; ARGS ; &KEY ; (SUPERCLASS java.lang.Object) ; INTERFACES ; CONSTRUCTORS ; METHODS ; FIELDS ; (ACCESS-FLAGS '(PUBLIC)) ; ANNOTATIONS ; (CLASS-LOADER (MAKE-MEMORY-CLASS-LOADER))) Many thanks.

Bug # 391
by Don Morrison 27 May '21

27 May '21

I don’t think I have the ability to comment on bugs in the issue tracker, or, if I do, I’ve not figured out how to do it. I hope sending mail to this list for the purpose is acceptable; apologies if not. I note that #391 was opened six years ago, but remains unfixed, and, apart from apparently being pushed off from release to release, seems not to have received any love for four years. I just wanted to add a note to it that it is still being encountered in the wild, and is, at least in one user’s case, causing some pain. File names containing asterisks may not be a good idea, but sometimes we have no control over the names of files we are given. It also means at least one (uiop:subdirectories), and probably many, UIOP functions sometimes fail in what can appear to be mysterious ways on ABCL, but not other implementations.
