[release candidate][16.1.2]

Dear all,

we slowly prepare for the next relese and I think it's time to test
things, if some changes didn't break builds etc., or if any serious
regressions has happened.

I would be grateful for performing tests with your configurations and on
the architectures you run (the more of them better it is), then we'll
have more complete picture what needs work. The most conveniant way to
process these things will be if you use Anton's cl-test-grid, which is
simply great for summarizing stuff:

https://github.com/cl-test-grid/cl-test-grid/tree/master/agent

Those interested in realease notes, please consult:
https://gitlab.com/embeddable-common-lisp/ecl/blob/develop/CHANGELOG
(section "Pending changes since 16.0.0").

If everything goes smoothly, version 16.1.2 should be out on 29th of
February, but if some problems araise (like a regression), we'll
postpone it.

Thanks for your help and see you around,
Daniel

ld-flags on win

Hi all,
I'm on my win64 build and I'm using asdf to define my system but with asdf:make-build or
asdf:load-bundle-op the ld-flags option to link some additional static
library to my fasl  is not passed to the linker.

So far I workaround with (si:setenv "_CL_" "bla bla bla") but it's not
ideal.

Am I doing something wrong or is a know issue?

Kindest regards.
bix

P.S. ECL is so fun. Great job.

Help on unit test

Hi all,
I make ECL compile with Win64 cl compiler, and so far it does not work
bad.
I want to run the unit test, and  I was able to do it manually
with some failure but I'm not 100% sure that I run those in the right
way.

It there some instruction that I can follow or can you tell me wich is
the proper way to run those unit test.

p.S. The buil system on windows need some makeup (on windows) and I was was wondering
that instead of using nmake I can fixup autoconf to work on msys2 on
windows platform with native cl compiler.

Cheers
f.

Conflicts when starting up various processes

Hi,

We have a few different c++ projects with ecl embedded, which when starting up, have ecl compiling and loading quite a bit of lisp code. 

If we start the various processes close enough in time, conflicts occur while compiling the lisp code. All is good if I wait for the lisp compilations between starting each process, but this is troublesome to do in production.

We believe this may be because the different processes might be using the same temporary folder for the compiled code or something of this nature. Is there any way to set the temporary path where ecl builds source code? Or some other hint you think might help?

Many thanks in advance for your help,

Diogo Franco

cl-redis problems

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

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?

Displaying lisp errors while running with save_eval

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@... . Correct ML address is
ecl-devel@... . I'm fast forwarding the mail there.

Generated code is readable, but it's a generated code after all. It's
not pretty.

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 .

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!

iolib and close

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

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( <at> ':pointer-void,0,~a)" c-name)
     to:
       ,(format nil "ecl_make_foreign_data( <at> ':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
