I have a similar problem with an older Ubuntu 14.04 machine. I installed using the tar.gz archive and then used install 'qtide' to install the Qt IDE. When I try to run it I get:
"/opt/j64_805/bin/libjqt.so" "could not resolve: state_run: Cannot load library /opt/j64_805/bin/libjqt.so: (libQt5WebSockets.so.5: cannot open shared object file: No such file or directory)" I don't have sudo on that machine and the administrator reports that libqt5websockets5 doesn't seem to be available for 14.04 at the moment. On a Ubuntu 16.04 machine I had no problem but it had a much more complete Qt5 installation including. /usr/lib/x86_64-linux-gnu/libQt5WebSockets.so.5 On Thu, Dec 22, 2016 at 2:35 PM, bill lam <[email protected]> wrote: > I'm puzzled why ijconsole/libj.so would depend on a Qt component. > I suspect the deb package did not refresh ld cache so that the > OS cannot pick up the newly installed libj.so > > Ср, 21 дек 2016, David Lambert написал(а): > > I run a fairly up-to-date ubuntu linux distribution.
