Issue installing on windows, built with msvc
by Fabrice Leal 30 Jan '19

30 Jan '19

took a second look at this and turns out "nmake" was not completing correctly... there was an error about not being able to spawn process "rc", and apparently there's some issue about the VS2015 command line not having it in the PATH. So I gave it another try with the VS2017 command line and now it compiles and installs fine. -- --- Fabrice Leal

Issue installing on windows, built with msvc
by Fabrice Leal 27 Jan '19

27 Jan '19

Hi, I think I found an issue installing ecl on windows, I followed the instructions on the INSTALL file, compilation with nmake seems to run ok, but when I run "nmake install prefix=C:\ecl" I get this error: for /f %i in ('type MODULES') do copy /Y %i "C:\ecl" NMAKE : fatal error U1077: 'for' : return code '0x1' Stop. At the msvc directory there's a "modules" file, but it seems empty... am I missing something?

Manually trigger the garbage collector
by Gunter Königsmann 02 Jan '19

Dear all, Is there any way to manually trigger ECL's garbage collector if I know that I have just created many temporary objects that I don't need any more?. Thanks a lot, and kind regards, Gunter.

(ARRAY DOUBLE-FLOAT (*)) is not a valid type specifier.
by Gunter Königsmann 13 Nov '18

13 Nov '18

Dear all, Just for interest/since you provided me with excellent help the last time even if I only had a vague problem description: Maxima, an open-source computer Algebra system comes with an optional lapack package that was generated from the original fortran source using a fortran-2-lisp utility. The Lapack package runs fine on gcl, clisp, ccl, allegro cl and - if sbcl is given enough memory to be able to compile it - on sbcl, too. On ECL it compiles just fine. But trying to actually use it results in (ARRAY DOUBLE-FLOAT (*)) is not a valid type specifier. Do you again have a magic idea on what we are doing wrong? The sourcecode of our lapack implementation would be here: https://sourceforge.net/p/maxima/code/ci/master/tree/share/lapack/ ...but it is quite a beast and - as it doesn't count as a "minimal example" I wouldn't expect you to look into it if the problem isn't clear from the error message. My hope is that we somehow need to make an alias for some variable type and everything starts working. Thanks in advance, and kind regards, Gunter.

defsystem+ecl question
by Gunter Königsmann 29 Oct '18

29 Oct '18

Dear all, I am currently trying to make maxima, a computer algebra system written in lisp, support out-of-tree builds: - The contents of the source tarball is kept in a directory and left completely unmodified and - all files generated during the build are kept in a potentially different directory. Since 2 of the lisp files containing (defparameter) commands are generated by the build scripts - the build process is started in the directory the output will end up in - an (mk:add-registry-location "$(top_srcdir)/src/") informs defsystem where to find the source tree and - in maxima.system all files that are in the build tree instead are marked as private-file: (:module final :source-pathname "" ;; These are not compiled, for whatever reason #-ecl :load-only #-ecl t :components ((:file "autol") (:file "max_ext") :private-file "share-subdirs") (:file "init-cl"))))) This seems to work fine in sbcl, clisp, ecl, openmcl, gcl and cmucl. And with ECL maxima seems to build fine, as well. But when I start a maxima that was compiled with ECL it generates a runtime error that the variables share-subdirs defines are not bound. I am no defsystem expert, neither a lisp expert so I expect to have done something obviously wrong. But as it works in all other lisps I've tried I hope ecl-devel is the right place to ask at. Thanks a lot, and kind regards, Gunter.

Oddities in ECL tests on Linux
by Robert Goldman 12 Sep '18

12 Sep '18

My Jenkins job is failing to test ECL successfully. What's interesting is that it looks like the tests are successful, but the checker is failing. Here's what I see in the transcript: These two expressions fail comparison with EQUAL: (UIOP/UTILITY:NEST (LISP-INVOCATION/LISP-INVOCATION:INVOKE-LISP :IMPLEMENTATION-TYPE (LISP-INVOCATION/ALLEGRO-VARIANTS:CURRENT-LISP-VARIANT) :CROSS-COMPILE NIL :IMAGE-PATH (UIOP/FILESYSTEM:NATIVE-NAMESTRING ASDF-TEST::IMG) :CONSOLE T :EVAL "(uiop:restore-image :entry-point 'hello:entry-point :lisp-interaction nil)" :RUN-PROGRAM-ARGS '(:OUTPUT :LINES :ERROR-OUTPUT T))) evaluates to ("No restarts available." "" "Top level in: #<process TOP-LEVEL>." "> ") '("hello, world") evaluates to ("hello, world") Oddly, when I try to run this at the command line, ECL throws to the interactive debugger on various signals and I have to restart it, before make test l=ecl will terminate successfully. I think I have seen this before, and it may be that ECL implicitly assumes that there will be some kind of C compilation tool chain present that I don't have, but I'm not sure about that. Suggestions for debugging would be welcom.

Loading "lparallel" hangs
by Robert Larice 06 Sep '18

06 Sep '18

Hello, can you provide me some hints for the following problem ? I've compiled ecl from git on a debian stretch machine. Then I've tried to compile the "qt" example, which did hang when loading "lparallel" So I started "ecl" from a shell, and did execute (ql:quickload :lparallel) which presents me: > To load "lparallel": > Load 1 ASDF system: > lparallel > ; Loading "lparallel" then the process fell silent. "top" doesn't show "ecl" to consume cpu cycles. Its waiting for something and doesn't proceed. Regards, Robert Larice
