segfault while testing lil
by Faré 14 Apr '16

14 Apr '16

lil passes all tests for me on sbcl, ccl, allegro, clisp, but on ecl I get: Condition of type: SEGMENTATION-VIOLATION Detected access to an invalid or protected memory address. Which precise test causes the segfault varies at each try. To reproduce: rlwrap ecl -eval "'(#.(require \"asdf\")#.(asdf:test-system :lil))" :b shows failure either in lil/test/stateful-map::test-stateful-map or in lil/test/pure-map::test-pure-map and probably at slightly different places therein. —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org For followers of most ideologies (openly religious or not), toleration is a concession of defeat.

error: 'aux_closure' undeclared (first use in this function)
by Tomas Hlavaty 10 Apr '16

10 Apr '16

Hi, I was curious how far would ecl get when compiling sbcl and found that ecl seems to struggle with compiling local functions (error log bellow). The problem is that the huge function parse-lambda-list being compiled has a flet (scan-opt/key) inside, which is compiled into a separate C function which does not see the other stuff, namely "volatile struct ecl_cclosure aux_closure;" is missing in the separate C function for flet scan-opt/key. I could not find a reduced testcase but I guess this is a bug in the ecl compiler?

Compiled program complaints on absent UIOP/OS and UIOP/PATHNAME
by Alexander Artemenko 03 Apr '16

03 Apr '16

Hi! I have created a command line program: https://github.com/svetlyak40wt/cl-jslog I've tried to build it with sbcl and it worked fine. But when I compiled it with ECL, I found that right after running, it outputs following error: Condition of type: SIMPLE-ERROR The packages ((UIOP/OS . #<UIOP/OS package>) (UIOP/PATHNAME . #<UIOP/PATHNAME package>)) were referenced in compiled file NIL but have not been created Available restarts: 1. (IGNORE) Ignore the error, and try the operation again Top level in: #<process TOP-LEVEL>. Tried ECL 16.1.4 on Ubuntu and ECL 16.0.0 on OSX. What is the reason of this error, and how to fix it? -- Alexander Artemenko (a.k.a. Svetlyak 40wt) Blog: http://dev.svetlyak.ru Photos: http://svetlyak.ru Jabber: svetlyak.40wt(a)gmail.com

Native thread
by Fabrizio Fabbri 31 Mar '16

31 Mar '16

Hi all, quick question. I’ve got my embedded ecl on a multi thread windows service. Before doing anything I call cl_boot. Then multiple request coming in served by different thread. At this point I call ecl_import_current_thread and the evaluate some lisp code with cl_safe_eval with Cnil as environment. After I call ecl_release_current_thread. Please note that those are native thread not created with gc wrapper. Are those evaluation happen in different lisp processes? Kindest regards F.

Hello, can I use ECL to write software for a chip without OS? In my case I'd like to write software for NXP1769 which is ARM Cortex M3, 64kB Ram, 512kB Flash. Andreas

ASDF 3.1.7 has been released
by Robert P. Goldman 23 Mar '16

23 Mar '16

ASDF 3.1.7 is a bugfix release, enhancing the 3.1.x ASDF series. To the best of our knowledge, it only fixes bugs, and should thus be a low-risk upgrade for inclusion in implementations. Thanks, as ever, to Faré for many fixes, and to other bug reporters and patch-suppliers. See the Changelog (below) for a summary of changes. Bug fix and portability release: * Fix compilation on Genera. * Fix UIOP:FILE-EXISTS-P for dotfiles on CCL. * Fix infinite loop in source registry configuration that can occur when there are cycles in the filesystem (typically caused by symlinks) on some CL implementations. * Miscellaneous bug fixes. * Documentation improvements. * Restore original Makefile. -- Robert P.
