Hi all, Today, I have investigated ABCL about is it possible to install libraries via quicklisp and how many libraries can be installed via quicklisp. Installation quicklisp itself has been successful and (surprisingly) it seems to be almost perfect. However, I have finally confront the following errors during installing (compiling?) cl-unicode library after installed some other libraries. ================================================== ; Loading "cl-unicode" ... ;;; Parsing Unicode file UnicodeData.txt ;;; Parsing Unicode file Scripts.txt ;;; Parsing Unicode file Blocks.txt ;;; Parsing Unicode file PropList.txt ;;; Parsing Unicode file DerivedAge.txt ;;; Parsing Unicode file BidiMirroring.txt ;;; Parsing Unicode file Jamo.txt ;;; Building hash tables ;;; Writing source file methods.lisp ;;; Writing source file hash-tables.lisp ;;; Writing source file lists.lisp ;;; Writing source file derived-properties ;;; Parsing Unicode file DerivedCoreProperties.txtjava.lang.ClassFormatError: Unknown constant tag 41 in class file org/armedbear/lisp/ASDF_TMP_hash_tables_2 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:634) at java.lang.ClassLoader.defineClass(ClassLoader.java:480) at org.armedbear.lisp.FaslClassLoader.findClass(FaslClassLoader.java:95) at org.armedbear.lisp.FaslClassLoader.loadClass(FaslClassLoader.java:77) at java.lang.ClassLoader.loadClass(ClassLoader.java:266) at java.lang.Class.getDeclaredConstructors0(Native Method) at java.lang.Class.privateGetDeclaredConstructors(Class.java:2406) at java.lang.Class.getConstructor0(Class.java:2716) at java.lang.Class.newInstance0(Class.java:343) at java.lang.Class.newInstance(Class.java:325) ... ================================================== Reproduce: 1. Install Quicklisp 2. (ql:quickload :cl-unicode) Is there any solution? Regards, Tomohiro Matsuyama
