problem loading shared libraries

[mickey]

Hello,
under Centos I installed a software, Webots (robotic stuff). When I launch it I got this message:


./webots-bin
./webots-bin: error while loading shared libraries: libQt5WebSockets.so.5: cannot open shared object file: No such file or directory

Does anyone can tell me if there is something wrong with my installation of QT, and how get rid of it?

Regards.

Maybe your centos installation didn't get the package for QWebSockets installed yet?
Or does the program come with its own Qt libraries?

Cheers,

Sorry I'm a bit novice. What you said doesn't help me. However, it seems Webots comes with its own QT library:


[michele@fiordaliso ~/webots/include/qt] # ll
total 32
drwxr-xr-x. 3 4096 Mar 8 16:58 QtConcurrent
drwxr-xr-x. 3 4096 Mar 8 16:58 QtCore
drwxr-xr-x. 3 4096 Mar 8 16:58 QtGui
drwxr-xr-x. 3 4096 Mar 8 16:58 QtNetwork
drwxr-xr-x. 3 4096 Mar 8 16:58 QtOpenGL
drwxr-xr-x. 3 4096 Mar 8 16:58 QtPrintSupport
drwxr-xr-x. 3 4096 Mar 8 16:58 QtWebSockets
drwxr-xr-x. 3 4096 Mar 8 16:58 QtWidgets

Anyway, I don't know how to proceed....

Is webots-bin a script?
Does it set the LD_LIBRARY_PATH variable so that it points to the Qt libraries it ships with?

webots-bin is an executable file
echo $LD_LIBRARY_PATH gives nothing...

HI again,
typing this below I get this interesting lines:


ldd webots-bin | grep not
./webots-bin: /lib64/libpng12.so.0: version `PNG12_0' not found (required by /home/michele/webots/lib/libfreeimage.so.3)
libjpeg.so.8 => not found
libjpeg.so.8 => not found
libjpeg.so.8 => not found

Any suggestion about how solve it? I don't know why but there's no the line about 'QT'......

You should probably check with the orgin/vendor/author of the software.
