compiling ecl android on MacOSX
by Pascal J. Bourguignon 01 Mar '16

01 Mar '16

Hello, We cannot compile ecl for android on MacOSX, because *nm* is used by gmp configure instead of $PLATFORM_PREFIX/bin/arm-linux-androideabi-nm With NM=$PLATFORM_PREFIX/bin/arm-linux-androideabi-nm in ecl/src/configure:5630, it passes: checking how to define a 32-bit word... .long but I'm not sure it's correct to hard wire this NM in ecl/src/configure; isn't it generated from autoconf? Well, configure passes, but then: ;;; Invoking external command: ;;; arm-linux-androideabi-gcc -I. -I/Users/pjb/src/android/ecl/build/ -DECL_API -I/Users/pjb/src/android/ecl/build/c -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -DANDROID -DPLATFORM_ANDROID -DUSE_GET_STACKBASE_FOR_MAIN -DIGNORE_DYNAMIC_LOADING -DAO_REQUIRE_CAS -g -O2 -fPIC -D_THREAD_SAFE -Dandroid -I/Users/pjb/src/android/ecl/src/c -c lsp/predlib.c -o lsp/predlib.o In file included from ./ecl/ecl.h:82:0, from ./ecl/ecl-cmp.h:29, from lsp/predlib.c:3: lsp/predlib.c: In function 'si_long_float_p': lsp/predlib.c:1067:42: error: 't_longfloat' undeclared (first use in this function) value0 = ecl_make_bool(type_of(v1x) == t_longfloat); ^ ./ecl/object.h:126:28: note: in definition of macro 'ecl_make_bool' #define ecl_make_bool(x) ((x)?

embedding ecl without (build-program)
by Juraj Variny 29 Feb '16

29 Feb '16

Hello, Is there is a way for ECL only to generate a bunch of .cpp files that can be fed to existing build system? I'm halfway there by generating C from my (ffi:c-inline) stuff like: (compile-file "src/common/lisp/lispinterface.lisp" :output-file "src/common/lisp/lispinterface.cpp"). But how do I initialize it on app startup? Looks like void init_fas_CODE(cl_object flag) should be called, but with what parameters? Some background: I am trying to embed ECL in a big C++ app with its own byzantine build system (ftjam with own layer on top of it). These C++ functions I am interfacing are not exposed externally (and I prefer not to), thus trying to load .fas file at runtime results in linker error. Also, I can't use (build-program) which won't work together with the build system. However, if (build-program) knows how to neatly pack whole initialization into one C function, that would solve the problem, too. Regards, Juraj

[rc2]
by Daniel Kochmański 19 Feb '16

Hey, I've finished running cl-test-grid on the rc2 (I hope I've fixed the issue – it wasn't the RNG, but defsetf bug). Could you Anton create reports based on these new tests? Thank you! There is no rush with it of course.

[release candidate][16.1.2]
by Daniel Kochmański 08 Feb '16

08 Feb '16

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 -- Daniel Kochmański ;; aka jackdaniel | Poznań, Poland TurtleWare - Daniel Kochmański | www.turtleware.eu "Be the change that you wish to see in the world." - Mahatma Gandhi

Conflicts when starting up various processes
by Diogo Franco 05 Feb '16

05 Feb '16

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
