Hi and welcome to devnet,

What version of Qt Creator ?
How did you install it ?
What modules does your application use ?
Do you mean when running through Qt Creator or from the command line ?

And just to be sure, are you using the Kit matching Qt 5.11 to build your application ?

[VARUNGUPTA1992]

@SGaist said in Cannot mix incompatible Qt library (version 0x50a01) with this library (version 0x50b01):

u using the Kit matching Qt 5

Yes, its using 5.11 in KIT

Are you using a dependency built with another version of Qt ?

[VARUNGUPTA1992]

@SGaist nope! as i said I am just learning now.. so all Qt libraries I am using right now is that came with package.

[SGaist]

Do you have LD_LIBRARY_PATH defined in your environment variables ?

[VARUNGUPTA1992]

@SGaist Its not set. But this time I abandoned that app and created a new project. Its working. I don't know what went wrong there. :(

Well thanks!
