Hello,
In order for CFFI to load, I need to load jna-4.2.2.jar.
Right now, I have to do something like this: (let ((jar-pathname #P"c:/Users/977315/.m2/repository/net/java/dev/jna/jna/4.2.2/jna-4.2.2.jar")) (java:add-to-classpath (namestring jar-pathname)))
To automate loading of ASDFs that require CFFI I tried to automate the process by adding a before method to 'load-op:
(eval-when (:compile-toplevel :execute :load-toplevel) (defmethod operate :before ((operation (eql 'asdf/lisp-action:load-op)) (component (eql :cffi))) (let ((jar-pathname #P"c:/Users/977315/.m2/repository/net/java/dev/jna/jna/4.2.2/jna-4.2.2.jar")) (java:add-to-classpath (namestring jar-pathname)))))
That did not work. I did read the ASDF manual, but could not figure out how to do it.
I suspect someone has figured out the right way. What is it?
Thanks,
Mirko
In case this helps, I launch ABCL using this script, which I call abcl.sh:
#!/bin/bash exec rlwrap java -classpath $HOME/sw/jna-4.1.0.jar:/usr/local/abcl-bin-1.4.0/abcl.jar:/usr/local/asm-5.2/lib/all/asm-all-5.2.jar org.armedbear.lisp.Main "$@"
jna lets me use CFFI (if I remember correctly), asm lets me use #'disassemble, rlwrap gives me readline support
However, I suspect that you're trying to get your ASDF system to load in other people's installations, without requiring them to use a script like the above. In that case, the above is useless.
---- What if you just place your first snippet into its own file, say "load-jna.lisp". List that as the first file in your ASDF system. When subsequent files load, they will find JNA already in place. Might that work?

Such "manual" loading of the JNA should be not be necessary in the default case of using ABCL-ASDF's Maven integration to download from the network, which is what [the ABCL specific portion of][cffi] does.
[cffi]: https://github.com/cffi/cffi/blob/master/src/cffi-abcl.lisp#L37
The
(require :jna)
refers to the [jna.asd][] definition, which is then passed to ABCL-ASDF for resolution.
[jna.asd]: https://gitlab.common-lisp.net/abcl/abcl/blob/master/contrib/mvn/jna.asd
"All" that you need to do to get this to work is to have a version of Maven installed. The [ABCL-ASDF][1] code should find the Maven executable in the JVM process path with which it will introspect the necessary operations needed to use the Mavane Aether infrastructure.
[1]: https://gitlab.common-lisp.net/abcl/abcl/blob/master/contrib/abcl-asdf/maven...
To go forward with your problems:
1. Do you have Maven installed or is there some reason in your deployment scenario that you do not wish to use it?
2. Without trying to load CFFI, does the following form load JNA from a fresh REPL?
(require :abcl-contrib) (require :jna)
Hi Mark,
Thanks for responding. See below for my replies

I do have Maven installed and in path, as given by mvn.bat -v .
I looked at abcl-asdf in the provided link and did some checking from within ABCL. The outputs of abcl-asdf::find-mvn, abcl-asdf::mvn-version were OK. Interestingly, I don't have abcl-asdf:mvn-home defined. Is my asdf 3.1.7.27 obsolete?
- Without trying to load CFFI, does the following form load JNA from a

(require :jna)
Triggers error: Java exception 'java.lang.ClassNotFoundException: com.sun.jna.Native'.
My jna is under my home directory in "c:/Users/977315/.m2/repository/net/java/dev/jna/jna/4.2.2/jna-4.2.2.jar"
That directory is non in CLASSPATH
Thanks,

It is packaged as part of `abcl-contrib.jar`.

It shouldn't be obsolete, as it is packaged as part of `abcl.jar`.

This indicates that for some reason your installation cannot locate abcl-contrib.jar.
For an ABCL installed via MacPorts, one can show the following details of the setup that may give a bit of insight into what a "healthy" version might look like:

How did you install ABCL? There should be two jar files, 'abcl.jar' and 'abcl-contrib.jar' which should both be located in the same directory. At runtime, when satisfying the "(require :abcl-contrib)", ABCL introspects the classpath on which it is launched to probe for 'abcl-contrib.jar'
Maybe you are using a custom invocation script?
A few more details on how you have installed ABCL locally and how you are invoking it would be helpful (i.e. "I downloaded abcl-1.4.0-bin.zip; unzipped in a directory, and I invoke it with this command").

Summary: abcl-contrib is fine, but there is an issue with Maven (even though mvn.bat is in path). Details below:

* Loading QUICKLISP, CFFI, leading to Maven error
Once I load quicklisp, I try loading CFFI, where I get
; Caught SIMPLE-WARNING: ; Unable to locate Maven executable to find Maven Aether adaptors.
mvn.bat is in my path. I can execute it from the Command shell. I really poorly understand Java setup, and its environment.
Also from within ABCL: (uiop/run-program:run-program '("where" "mvn.bat") :output :string) "C:\Program Files\apache-maven-3.3.9\bin\mvn.bat " NIL 0
A few more details on how you have installed ABCL locally and how you
are invoking it would be helpful (i.e. "I downloaded abcl-1.4.0-bin.zip; unzipped in a directory, and I invoke it with this command").
I don't recall how I installed it, although it was not straightforward. For example, I extracted the startup bat file from the online repository and formatted it so it would work.

Summary: abcl-contrib is fine, but there is an issue with Maven (even though mvn.bat is in path). Details below:
After (require :abcl-asdf), I invoke (abcl-asdf:find-mvn) TWICE. - First time, I get error about missing Maven executable - Second time, it finds Maven executable.
After that second time, CFFI loads cleanly.
Summary of steps to load CFFI from abcl --no-init: (require :abcl-contrib) (require :abcl-asdf) (abcl-asdf:find-mvn) ; issues warning about non-existant executable (abcl-asdf:find-mvn) ; returns mvn.bat path (load "~/quicklisp/setup.lisp") (ql:quickload :cffi) ; works

I'm not entirely sure why that works, but congratulations on getting something working! I don't develop under Windows, mainly from a lack of free licensing terms that don't have to be renewed every 90 days, so sometimes the state of functionality running ABCL under MSFT gets a little more divergent than I would like.
[The mechanism by which ABCL finds and executes Maven Aether][1] is being re-worked for abcl-1.5.0 to be more intelligent in providing restarts and diagnostics.
I will endeavor to test abcl-1.5.0-dev to make sure these new changes work better for finding Maven under Windows than is the current state with abcl-1.4.0.
