I recommend trying out a newer > version > of ecl (16.1.3 or the current develop branch from the git repository). I see your point, but have two comments: 1. If this really *is* an ECL bug, then shouldn't the Ubuntu package be updated and fixed? ASDF is supposed to work on the ECL that users will have, not only on the one that developers have. 2. I don't see a way to get a new ECL except by pulling from Gitlab and building. I do not have the time to run around building all available lisp implementations from source (and, again, ASDF should work on the versions of the implementations that users actually have, which means the ones provided by the packaging systems on the platforms). I build only SBCL, because that's an implementation I build anyway, for my work needs. Faré had the energy to play with all the different implementations in a substantial way, but I do not. So if the released version of an implementation is broken, I will simply regard that implementation as broken. If the *released version* of an implementation is broken for long enough (I'm looking at you, clisp), it will become unsupported by ASDF. Unsupported means "patches will be accepted, but I will no longer run the tests, and test failure on an unsupported implementation will not be a reason to hold up an ASDF release." Note that at the moment *all* implementations are essentially unsupported on Windows, since I have lost my Windows VM, and even if I got it back, I would have no way to develop on Windows. If you are a Windows user and this bothers you, I would be happy to support you in setting up a test environment, and even more happy to help you learn to patch ASDF. But even someone who doesn't want to patch ASDF, but who would be willing to run the test suite (or help figure out how it could be run through, e.g., Travis), would be a great help. > > Am 30.08.2018 um 21:51 schrieb Robert Goldman: >> I'm experimenting with your changes now but, for some reason that I >> don't understand, when I run the tests as |make l=ecl| interactively >> on >> Ubuntu (using the Ubuntu ECL package |16.1.2-3|), signals are >> throwing >> me into the interactive debugger, instead of being caught.

I don't seem to receive emails to the list by François-René Rideau
by Spiros Bousbouras 30 Aug '18

30 Aug '18

When I look at https://mailman.common-lisp.net/pipermail/ecl-devel/2018-August/thread.html I see 3 posts by him all in the thread "Oddities in ECL tests on Linux" .I haven't received any of them (they're not in spam either). Before this month last time he posted on the list was on 2016-12-27 with Message-ID: <CAN7nBXcjskn=J3oRJTBJVt1mJBY+DKVs-hFjOtTHtB0aoenp6w(a)mail.gmail.com> and I received that one (and previous emails by him). So the question is whether anyone else has the same problem. Spiros Bousbouras

Using a cl_object in Lisp
by Stewart M. 29 Jul '18

29 Jul '18

I am using CFFI with ECL to interface to a C++ library, which has a C++ class with a data member of type 'cl_object'. Simplified, my C++ code is: class LispObject { public: cl_object object; }; extern "C" cl_object getObject(LispObject* lo) { return lo->object; } extern "C" void setObject(LispObject* lo, cl_object clo) { lo->object = clo; } The full code is: https://common-lisp.net/viewvc/clive/trunk/src/extensions/corral/CliveCorra… Can I somehow declare the 'cl_object' type for the 'getValue()' and 'setValue()' functions using CFFI 'defcfun' to get and set ECL objects? Is there a technique using the lower-level FFI? I am looking for a way to do this without compiling C code embedded in Lisp, which I am aware ECL can do. Thank you for any ideas! -- Stewart Milberger Kavalogic, Inc.

how do you build the embed example
by blackthirt33n 28 May '18

28 May '18

How do you build the embed example "ecl-16.1.3\examples\embed" with the visual studio 2017 tools? I have no problem compiling running the Makefile in the msvc directory but the files up level are problematic. James

defstruct :predicate failure
by Peter Keller 09 May '18

Hello, I ran into a situation where I think ECL 16.1.3 has a bug in it: Linux violet > ecl ;;; Loading "/home/psilord/quicklisp/setup.lisp" ;;; Loading #P"/usr/local/lib/ecl-16.1.3/asdf.fas" ECL (Embeddable Common-Lisp) 16.1.3 (git:UNKNOWN) Copyright (C) 1984 Taiichi Yuasa and Masami Hagiya Copyright (C) 1993 Giuseppe Attardi Copyright (C) 2000 Juan J.

If the argument is provided and is nil, no predicate is defined. A predicate can be defined only if the structure is named; if :type is supplied and :named is not supplied, then :predicate must either be unsupplied or have the value nil. " In this case, :type is supplied, :named is not supplied, and therefore :predicate must either be unsupplied or have the value NIL. In my case, it has the value NIL. It appears to me that I have written legal CL, but ECL doesn't think so. Thank you! -pete

ASDF 3.3.2 released
by Robert Goldman 04 May '18

04 May '18

Dear Lisp implementors and maintainers, Today we release ASDF 3.3.2, the second bugfix release for the 3.3 release series. Of primary interest in this release are 1. Multiple fixes in handling misnamed (or "legacy-named," if you prefer) secondary systems ("foo-test" instead of "foo/test"). Thanks to Eric Timmons, there is also a similar fix for package-inferred-systems. 2. Fix an annoying warning message for compute-action-stamp. 3. Add support for the Mezzano implementation (thanks to E. Housel, H. Harrington). 4. Miscellaneous minor fixes and documentation tweaks. We urge implementations that are currently bundling previous versions of ASDF -- and especially those bundling 3.3.0 or 3.3.1 -- to upgrade to 3.3.2 at their earliest convenience. Immense thanks, as always, to Fare Rideau. Also thanks to the many bug reporters and patch submitters (see the Changelog), and to Anton Vodonosov and Dave Cooper for help with testing. Here is the changelog entry for 3.3.2: cl-asdf (2:3.3.2-1) unstable; urgency=low Bug fix release: * Dependency tracking: fix bugs in handling misnamed secondary systems. We now distinguish between "syntactic" and "semantic" primariness, properly warn in case a secondary system is misnamed, yet properly recompile or avoid spurious recompilation depending on whether there or not is a conflict or redefinition. Similarly handle package-inferred-system (thanks to Eric Timmons). Better warning in a fishy case of compute-action-stamp. * UIOP: Add package location information to define-package on SBCL. * Upgrade: fix issue with asdf/bundle. * Portability: add support for Mezzano (thanks to E. Housel, H. Harrington) * Documentation: add discussion of best practices. * Package-inferred system: Improve source file handling. * Test and documentation improvements. -- Francois-Rene Rideau <fare(a)tunes.org> Thu, 03 May 2018 22:46:19 -0400
