building ecl with gcc-15 / c23 C standard

I had a go at building ecl with C compiler using c23 mode (i.e. -std=c23 argument in CFLAGS) and apart from an easy to fix "typedef bool" issue, there is more, and quite hard to understand: CFLAGS="-std=c23" ./configure && make [...] dpp: /home/dima/software/ecl/src/c/read.d -> read.o.c[...]/home/dima/software/ecl/src/c/read.d: In function ‘init_read’:/home/dima/software/ecl/src/c/read.d:2023:39: error: passing argument 1 of ‘ecl_make_cfun’ from incompatible pointer type [-Wincompatible-pointer-types] 2023 | #define make_cf3(f) ecl_make_cfun((f), ECL_NIL, NULL, 3) | ^~~ | | | union cl_lispunion * (*)(union cl_lispunion *, union cl_lispunion *)/home/dima/software/ecl/src/c/read.d:2047:29: note: in expansion of macro ‘make_cf2’ 2047 | | ^ In file included from /home/dima/software/ecl/build/ecl/ecl.h:82, from /home/dima/software/ecl/src/c/read.d:16:/home/dima/software/ecl/build/ecl/external.h:427:58: note: expected ‘cl_objectfn_fixed’ {aka ‘union cl_lispunion * (*)(void)’} but argument is of type ‘union cl_lispunion * (*)(union cl_lispunion *, union cl_lispunion *)’ 427 | extern ECL_API cl_object ecl_make_cfun(cl_objectfn_fixed c_function, cl_object name, cl_object block, int narg); | ~~~~~~~~~~~~~~~~~~^~~~~~~~~~ see https://gitlab.com/embeddable-common-lisp/ecl/-/issues/775 Any ideas how to fix this?

ECL runs Maxima in a browser
by Raymond Toy 27 Jan '25

27 Jan '25

Thought you would be interested to know that Marius Gerbershagen has used ecl to compile Maxima to wasm to run in a browser. I believe it's a pretty complete implementation with fancy TeX display of formulas and nice graphics via gnuplot compiled to wasm. See it at http://maxima-on-wasm.pages.dev/ -- Ray

CDR for Package-Local Nicknames [Feedback Request]
by Alexander Fedorov 06 Jul '24

06 Jul '24

Dear all, Over 10 years ago, SBCL implemented the Package-Local Nicknames (PLNs) extension. Since then, PLNs have also been adopted by multiple implementations (ABCL, CCL, ECL, Clasp, Allegro CL and LispWorks) and are now widely used in many projects. However, PLNs are still considered experimental, as stated in the SBCL manual, since there is no formal specification for them, and each implementation interprets various corner cases differently. While the need for a specification has been previously discussed, I was unable to find any publicly accessible draft for one. Therefore, I have drafted a specification intended to become a CDR document. I initially wrote this draft about a year ago and have recently revised it. You can find the latest version here: https://gleefre.github.io/cdr-package-local-nicknames/index.html. There are currently nine unresolved standardization issues, each with at least one proposed resolution. Input on those issues would be particularly helpful, but any feedback is welcome! P.S. I am sharing this link across multiple platforms to reach as many lispers as possible. This includes various mailing lists (Lisp Pro, CDR-discuss and -devel for various CL implementations); IRC channels (#commonlisp and implementation-specific ones); the Lisp Discord server; several Telegram groups; and a post on Reddit. If you have any suggestions for additional places to share the link, please let me know. My apologies to those receiving this message multiple times. Best regards, Alexander Fedorov.

Crash on call of cl_boot from dll init function
by jasonchandler＠pm.me 25 Jun '24

25 Jun '24

Hi, I've been having some issues booting ECL in programs where I am not in control of the main function entry. I've tried running the main program with gdb after compiling ECL with debug enabled, but I haven't gotten any useful output so far, just that cl_boot triggered an exit with code 1. I will continue to hit my head against the wall with it. It's clear that my program is crashing on cl_boot though, which I'm calling when the dll is initialized like so: char* argv; char** pargv; argv = "app"; pargv = &argv; cl_boot(1, pargv); I got this weird setup from some notes I took a number of years ago, but I can't seem to find this usage anywhere, so it might be related. Off-hand, I've also tried using cl_boot with 0 and NULL as the arguments, but the result is the same. I am using MSVC-compiled ECL and I can still call ecl_get_option(ECL_OPT_BOOTED) to see that it is clearly not already booted. Would anyone happen to know if I'm doing something obviously wrong? Thanks! Jason Chandler
