Is this thing on? Cross-compiling for ARM
by Erik Winkels 26 Sep '20

26 Sep '20

Hi all, Not sure if this is still the place to be for ECL questions but here it goes: I'm having issues cross-compiling ECL for ARM and since this is actually the first time I'm cross-compiling stuff ever I'm kinda stuck. I want to cross-compile for ARM, *but* it is not for Android it is for Sailfish OS. There's an (unofficial) ECL package available for it but I cannot find a way to contact the author and also don't want to depend on it. On my Void Linux machine I've installed `cross-arm-linux-gnueabi` and can do a `./configure --host=arm-linux-gnueabi` but when I do `make` I get the following errors: ``` dpp: /home/brainrot/projects/eclrepl/3rd-party/ecl-git/src/c/list.d -> list.o.c Unknown symbol: mp::compare-and-swap-car Unknown symbol: mp::atomic-incf-car Unknown symbol: mp::compare-and-swap-cdr Unknown symbol: mp::atomic-incf-cdr /home/brainrot/projects/eclrepl/3rd-party/ecl-git/src/c/list.d: In function 'mp_compare_and_swap_car': /home/brainrot/projects/eclrepl/3rd-party/ecl-git/src/c/list.d:670:26: error: 'unknown' undeclared (first use in this function) return ecl_compare_and_swap(&ECL_CONS_CAR(x), old, new); ^~~~~~~ /home/brainrot/projects/eclrepl/3rd-party/ecl-git/src/c/list.d:670:26: note: each undeclared identifier is reported only once for each function it appears in /home/brainrot/projects/eclrepl/3rd-party/ecl-git/src/c/list.d: In function 'mp_atomic_incf_car': /home/brainrot/projects/eclrepl/3rd-party/ecl-git/src/c/list.d:678:26: error: 'unknown' undeclared (first use in this function) return ecl_atomic_incf(&ECL_CONS_CAR(x), increment); ^~~~~~~ /home/brainrot/projects/eclrepl/3rd-party/ecl-git/src/c/list.d: In function 'mp_compare_and_swap_cdr': /home/brainrot/projects/eclrepl/3rd-party/ecl-git/src/c/list.d:686:26: error: 'unknown' undeclared (first use in this function) return ecl_compare_and_swap(&ECL_CONS_CDR(x), old, new); ^~~~~~~ /home/brainrot/projects/eclrepl/3rd-party/ecl-git/src/c/list.d: In function 'mp_atomic_incf_cdr': /home/brainrot/projects/eclrepl/3rd-party/ecl-git/src/c/list.d:694:26: error: 'unknown' undeclared (first use in this function) return ecl_atomic_incf(&ECL_CONS_CDR(x), increment); ^~~~~~~ make[2]: *** [Makefile:88: list.o] Error 1 make[2]: Leaving directory '/home/brainrot/projects/eclrepl/3rd-party/ecl-git/build/c' make[1]: *** [Makefile:144: libeclmin.a] Error 2 make[1]: Leaving directory '/home/brainrot/projects/eclrepl/3rd-party/ecl-git/build' make: *** [Makefile:72: all] Error 2 ``` I get the feeling I'm forgetting some necessary steps. Thanks, Erik

least-positive vs least-positive-normalized
by Raymond Toy 13 Feb '19

13 Feb '19

With ecl 16.1.3, I noticed that least-positive-double-float and least-positive-normalized-double-float are exactly equal. This is allowed, but ecl can work with denormals since (/ least-positive-normalized-double-float 10) is printed correctly. Maybe these two values should be different? Or maybe ecl really meant to turn on flush-to-zero so that no denormals can occur? -- Ray?

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

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.
