cl-redis problems
by Diogo Franco 11 Jan '16

11 Jan '16

Hi, I've been using cl-redis with ecl without problems, but recently i have some trouble when installing on new systems. rutil is a dependency installed by quicklisp when doing quickload on cl-redis, and i've been getting: "There is no method on the generic function PRINT-OBJECT that agrees on qualifiers NIL and specializers (HASH-TABLE T)" This is the ecl that's installed via apt-get, ecl-13.5.1. I did notice that sbcl finds the method correctly when doing "(find-method #'print-object nil '(hash-table t))", while ecl also gives the error above. Any idea on how to further investigate this? Thanks in advance!

How to compile executable with external dependencies
by Alexander Artemenko 05 Jan '16

05 Jan '16

Hi! Is there a way to compile a lisp programm which uses something like Drakma? Or ECL is only able to compile separate lisp files one by one? -- Alexander Artemenko (a.k.a. Svetlyak 40wt) Blog: http://dev.svetlyak.ru Photos: http://svetlyak.ru Jabber: svetlyak.40wt(a)gmail.com

Displaying lisp errors while running with save_eval
by Diogo Franco 08 Dec '15

08 Dec '15

Hi all, Uncaught error conditions in lisp code don't display in *standard-output* for me, when ecl is running embedded in c (i presume the reason is that i'm calling the lisp functions using save_eval()). My workflow on the shell while developing is then to do ctrl-c which drops me to the REPL, and to manually execute the functions, which will print the error. I'm no expert on the inner workings of ecl, so forgive me if this is a dumb question, but is there some way to get the errors in *standard-output* even when using save_eval()? Thanks in advance, Diogo Franco

Re: Inspecting intermediate C files

Hi, I'm not sure if I miss something, but this mail seems to be sent to the ecl-devel-owner(a)common-lisp.net . Correct ML address is ecl-devel(a)common-lisp.net . I'm fast forwarding the mail there.

To prevent ECL from deleting these intermediate files you need to set special variable c::*delete-files* to nil. (setf c::*delete-files* nil) Intermediate files are *.c, *.h and *.data . The last one contains some untranslatable expressions (rare occasion – if you work with infinities for instance) and debugging/reflection information (like the path to the source file). This problem has been tacled by Earl Ducaine here: https://github.com/earl-ducaine/stupid-ecl-tricks-1 . > > Can you help me figure out how to generate them?

I'm now in-process of revising manual and rewriting it into texi sources. I'll keep in mind to document this. It would be great if you could file an issue on gitlab.com/embeddable-common-lisp/ecl/issues (with the label "documentation"). Thanks! > > Thanks!

iolib and close
by Alessandro Serra 26 Nov '15

26 Nov '15

Dear all, compiling "iolib-tests" I received the following error: #<IPv4 datagram socket, closed 00000000050f3660> is not of type STREAM. [Condition of type TYPE-ERROR] I have seen that in "clos/streams.lsp" the following method is defined: (defmethod close ((stream t) &key abort) (declare (ignore abort)) (bug-or-error stream 'close)) Removing the method above with: (remove-method #'gray:close (find-method #'gray:close '() '(t))) I was able to compile iolib-tests and run the tests. Did 71 checks. Pass: 59 (83%) Skip: 0 ( 0%) Fail: 12 (16%) Regards, Alessandro

ffi:defcallback with cxx
by hiro hiro 14 Nov '15

14 Nov '15

Hello, I compiled ecl16.0.0 with option "--with-cxx". Then I use ffi:defcallback function like (ffi:defcallback yyyy :void () ..... ) then compile-file (compile-file "xxxxx.lisp" :c-file "xxxxx.cpp" :system-p t) I received error message as follows (freebsd10.1 clang++) xxxxx.cpp:162:8: error: no matching function for call to 'ecl_make_foreign_data' T0 = ecl_make_foreign_data(ECL_SYM("POINTER-VOID",1381),0,ecl_callback_0) I try as follows in src/cmp/cmpcbk.lsp & src/new-cmp/cmpc-cbk.lsp line 44 from: ,(format nil "ecl_make_foreign_data(@':pointer-void,0,~a)" c-name) to: ,(format nil "ecl_make_foreign_data(@':pointer-void,0,(void*)~a)" c-name) after that, I did not receive error message and ffi:callback work fine. Would you let me know what your thoughts are on this matter. hirohiro447

10 Nov '15

Dear all, for the last few weeks I was working on the ECL Android integration. I've managed to create a basic app which is swank-capable. More info here: https://common-lisp.net/project/ecl/ I'll appreciate all the feedback :) Regards, Daniel -- Daniel Kochmański | Poznań, Poland ;; aka jackdaniel "Be the change that you wish to see in the world." - Mahatma Gandhi

ECL & IPhone Port
by Evrim Ulu 07 Nov '15

07 Nov '15

Dear List, I've been one of the Android port and I am glad to see that Daniel is working in order to merge the port into the master branch soon. I know that he's building other nice perks for Android devs. In the meantime, I would like to proceed into building a sound IPhone port. In this regard, I am looking for capital to fund the development. Please contact me if you like to see support for IPhone platform on the master branch. Best, evrim.

GC and Threading
by Bix 06 Nov '15

06 Nov '15

Hi, just two quick question: 1. Is it possible to disable the threading model and have multiple thread to eval the code or have one ECL per thread? 2. Can the garbage collector be disabled at all and have the memory managed in a reference counting fashion? I like to embed the ECL in my multithread application but I've got very restrictive constrain about thread and memory: * I can not spawn new thread but I've got concurrent thread to execute ecl call. * A component that bring GC would probably not be accepted and I'm wondering if there is an alternative to that in ECL, or at least have more control how/when GC will be run. Can you point me out where to look in the source code to understand those aspect of ECL? Thanks in advance. f.
