I'd like to try J and the IDE, but have run aground during installation. I hoped someone might be able to point me in the right direction. I'm on ubuntu 19.10.
I followed the directions at https://code.jsoftware.com/wiki/System/Installation/J901/Debian for the installation: -- download the .deb -- sudo dpkg -i j901_amd64.deb -- sudo ijconsole -- install 'qtide' After the above, I found the below exception: % jqt "libjqt.so.9.01" "could not resolve: state_run:\n\nCannot load library libjqt.so.9.01: (libjqt.so.9.01: cannot open shared object file: No such file or directory)" And sure enough, when I try to locate libjqt.so, I get nothing % locate libjqt % which jqt /usr/bin/jqt On https://code.jsoftware.com/wiki/Guides/Qt_IDE/Install, I found the following, and was hopeful their absence could be related (though I would have expected a different shared object to be missing). Ubuntu/Linux Mint Two issues have been reported: you may need to install the Qt webkit, websockets, multimedia libraries, as: sudo apt-get install qt5-default sudo apt-get install libqt5webkit5 sudo apt-get install libqt5websockets5 sudo apt-get install libqt5multimediawidgets5 There were, indeed, qt libraries to install. But the problem persisted after their installation. I ran another round of sudo ijconsole, trying the different installs, hoping something would get the missing object into place, but none of the below did. -- install 'all' -- install 'qtide' -- install 'full' There is a warning in the output that seems related. Does anyone know a fix for this, or options for more verbose output, or what might be triggering the failure to install? Example from install 'full' below: % sudo ijconsole install 'full' Updating server catalog... Installing 1 package Downloading base library... Installing base library... Done. Installing JQt binaries... install libjqt.so to /usr/lib/x86_64-linux-gnu/. update-alternatives: warning: forcing reinstallation of alternative /usr/bin/jqt-9.01 because link group jqt is broken Finished install of JQt binaries. Exit and restart J using jqt The "update-alternatives: warning: ..." is concerning, and the failure of "install libjqt.so to /usr/lib/x86_64-linux-gnu/" makes me suspicious there is something the installer doesn't like. Any advice would be appreciated Thanks ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
