[Interest] big trouble with QCoreApplication

[Freddy Martinez]

Hi Mike, and thanks for your answer….

I had sent you a print screen, as you could see, the line 63 is

QCoreApplication a(argc,argv)

the only thing I suppose  that it’s happend is that in /usr/lib/x86_64/ I have other qt5 libraries installed but for qt 5.4.2 version… maybe when I’m trying to run the application is crahsed because is linking against 5.4.2 and I’m compiling with 5.5.1.

I had download the offline installer and i had create a Qt folder on my home directory, there I had installed Qt 5.5.1…

that is my environment 

any advise ?

regards
