[Qt-interest] Adding custom widget plugins error/problem

[miroslav]

Hi All,

the last mentioned error I have fixed with adding library to *.pro file
No I can run make without error.

Problem is, when I want to execute the program - I'm getting following
error:

"error while loading shared libraries: libworldtimeclockplugin.so:
cannot open shared object file: No such file or directory"


The path to the library is correct because of "make" run without errors.


Where am I making mistake? Custom widget plugin is a shared library?
Should I add a custom widget to a *.pro file? Or?

Hope you can help me..

Thanks,
Miroslav



Please do you know that what can be the problem?
