(Tested by Hakan Kjellerstrand) -------------------------------------------------------------------------- -- 6 Jan 2020 Hakan Kjellerstrand Big integer bug report (Fixed in above patch) More details in https://www.mail-archive.com/pop-forum@cs.bham.ac.uk/msg00341.html Here is a strange behaviour in Poplog 16 using round and round(sqrt(i)): vars i; for i from 2 to 10000 do [^i ^(2**i) ^(round(sqrt(2**i)))]=>; endfor; Poplog 16 throws an error for 2**126: """ ..... ** [123 10633823966279326983230456482242756608 3260954456333195264] ** [124 21267647932558653966460912964485513216 4611686018427387904] ** [125 42535295865117307932921825928971026432 6521908912666390528] <<<<<<< System Error: Signal = 8, PC = 00000000005B31F7 >>>>>>> [NB now fixed] -------------------------------------------------------------------------- -- 5 Jan 2020 Use getpoplog.sh to download Poplog V 16 (with/without '-nopie') A single 'fetch and install script' is available that downloads items to be used to create a poplog V16 installation. http://www.cs.bham.ac.uk/research/projects/poplog/V16/getpoplog.sh Download it, make it executable and run it to install poplog. Read the comments for more information. The latest version of getpoplog.sh accepts an optional extra parameter -nopie which determines whether or not poplog (basepop11) should be linked as a position-independent executable (PIE). PIE is not permitted in some recent versions of linux (e.g. Arch and recent versions of Debian). The extra parameter '-nopie', if present, invokes a change to exclude PIE for those versions of linux. At present this mechanism cannot detect automatically whether the extra parameter is required. So, to install poplog on Arch or Debian 9 and "testing", run this command as getpoplog.sh -nopie For other versions of linux that may not yet work, and '-nopie' can be omitted, e.g. for older versions of Fedora. It doesn't seem to be required for Fedora 31, but can be used without any bad effect, as far as I can tell. -------------------------------------------------------------------------- -- 2 Jan 2020 Moved tar files into DL library All the tar files and scripts used during download are now in the DL ('Download') subdirectory http://www.cs.bham.ac.uk/research/projects/poplog/V16/DL -------------------------------------------------------------------------- -- 1 Jan 2020 Hakan Kjellerstrand tested new script | What a great start of the new year, Now I got Poplog 16 to work! The magic that got it to work on my Linux Ubuntu 18.04 box was the -nopie flag to getpoplog.sh . Excellent! There are still some issues that I will check out in more detail, but running all the first 50 Project Euler programs is now 2s faster than the earlier 15.65 version. (See http://hakank.org/poplog/ for the programs.) -------------------------------------------------------------------------- -- 31 Dec 2019 Aaron Sloman script with optional -nopie parameter does everything A single download script with optional -nopie parameter does everything I felt that what I was doing previously was too messy, with different install scripts for different purposes. So a single script with an optional '-nopie' flag is available. https://www.cs.bham.ac.uk/research/projects/poplog/V16/getpoplog.sh -------------------------------------------------------------------------- -- 11 Dec 2019 introduced AREADME.html This file is now partly superseded by http://www.cs.bham.ac.uk/research/projects/poplog/V16/AREADME.html __________________________________________________________________________ -- 28 Dec 2019 Tested successfully on Arch by Andreas Eder ...after installing the nopie patch manually > 2a) patch 'asmout.p' to add '-no-pie' option > patch -p1 < nopie.diff -------------------------------------------------------------------------- -- 16 Jul 2019 new download link: latest_poplog_base.tar.bz2 Aaron Sloman: To save the need to edit this and other documents whenever there's a new version of poplog_baseN.tar.bz2 I've created a symbolic link latest_poplog_base.tar.bz2 That needs to be used in combination with meeting linux library requirements for poplog, as explained in https://www.cs.bham.ac.uk/research/projects/poplog/V16/AREADME.html#installation-process Use this script to start a download and install: https://www.cs.bham.ac.uk/research/projects/poplog/V16/getpoplog.sh After downloading run getpoplog.sh with or without '-nopie' as explained above. -------------------------------------------------------------------------- -- NCURSES NEWS Sun, 14 Jul 2019 Waldek Hebisch wrote to the pop-forum mailing list: (slightly edited): "It was noted that some Linux systems have only ncurses version 5, while others have only version 6. Executables linked to non-present version of the library can not run, so it is not possible to have a single executable that runs on a large variety of Linux system and which is linked with ncurses. So to ease recompiling Poplog I have created corepop which does not link to ncurses. ATM I do not know what is best way to do this. I simply removed 'termcap.p' from 'pop/src'. Moving it to 'pop/ved/src' and adjusting sources so that they still compile allow building 'basepop11' linked to ncurses from the same source. I do not know why 'termcap.p' is in 'pop/src'. It seems that in the base system only ved needs termcap (more precisely terminfo) functions so it seem reasonable to move 'termcap.p' to the Ved directory. Is there a better solution?" http://www.math.uni.wroc.pl/~hebisch/poplog/poplog_base6.tar.bz2 [Now out of date] This tarball contains a new corepop. I also slightly modified 'pglink' so that it does not build 'rsvpop11' when '-core' is given. There are no other changes compared to version 5 tarball (in particular corepop built from the tarball is linked to ncurses). [7 Jan 2020: Note by A.S. This strategy seems to have worked, as far as I can tell after using V16 for some time, with later bugfixes included.] ============== For more information see http://www.cs.bham.ac.uk/research/projects/poplog/freepoplog.html
