Hello. When I run the following command: java -cp jna.jar;C:\Users\anton\unpacked\abcl\abcl-bin-1.0.0\abcl.jar org.armedbear.lisp.Main --batch --eval "(ql:quickload :drakma)" an error occurs: Armed Bear Common Lisp 1.0.0-svn-13663 Java 1.6.0_26 Sun Microsystems Inc. Java HotSpot(TM) 64-Bit Server VM Low-level initialization completed in 0.967 seconds. Startup completed in 3.725 seconds. Loading C:\Users\anton\.abclrc completed in 17.21 seconds. To load "drakma": Load 1 ASDF system: drakma ; Loading "drakma" .............. Caught PROGRAM-ERROR while processing --eval option "(ql:quickload :drakma)": Unrecognized keyword argument :CONVENTION I think it's cffi error (cffi is the only library having the :convention in source code). As you see in my command line, i load drakma. Drakma depends on cffi via cl+ssl. If I do (ql:quickload :cffi) it works, but I assume the error happens during macro-expansion of some CFFI macro, that's why loading is not enough, some code using cffi should be loaded too. Best regards, - Anton
