How to get output Screen
-
I have to installed QT creator ver 4.8 and i have one project, it developed QT creator ver 4.5 in Linux platform on 2008. Now i want to update some changes for feature enhancement. i had to try to compile and run the project successfully, but i could't get the output screen. the (.pro) file generated only the .exe file only. How can i get the resultant output UI screen, what will i made for that.

Hi,
if you mean print the
qDebug()
output to the console you should addCONFIG += console
to your .pro file
-
Here is the error,
b77ea000-b77eb000 r--p 002c0000 08:01 1966228 /usr/lib/locale/locale-archive

The program has unexpectedly finished.

Which plaftorm??

@mcosta Linux using C++

sorry, I understood you was on Windows (
CONFIG += console
works on it)@Arasu said:

What means??
-
I couldn't get the User Interface screen, but it had to create .exe file direcly
-
i am thinking that, the code which i'm having will be compatible for both windows and Linux(ubuntu). right?
-
Depends on you code?
Is a 100% Qt code?? -
Actually, to my knowledge, the previous developers have developed the code using QtCreator only. apart from that how can i make sure it is completely Qt COde?
-
@Arasu Looking at this output
b77ea000-b77eb000 r--p 002c0000 08:01 1966228 /usr/lib/locale/locale-archive b77eb000-b77ed000 rw-p 00000000 00:00 0 bfaa8000-bfac9000 rw-p 00000000 00:00 0 [stack] The program has unexpectedly finished. /home/dyansys/Desktop/ECScope/ecg12i-build-desktop-Qt_4_8_1_in_PATH__System__Release/ecg12i exited with code 0
The code does compiles properly but seems it crashes at some point during runtime. Something related to
locale
perhaps. You will need to debug it. -
Thank you!
Shall i know how to debug the code in QT creator? Why because previously the project created in QT creator version 4.3, but now i am using version 4.8, this version deprecated some of the default methods.
-
-
@p3c0 Can you give some example code for this qDebug() ?
-
-
Thank you!
Is this for Linux using C++ ah?
-
@Arasu qDebug() will work on all platforms since it is a Qt API.
And using QtCreator you will have to use valgrind for debugging. It comes for Linux. -
Now im trying both linux and windows, but both environment i am getting same issue, can you suggest for windows.
-
@Arasu If it is the same issue then if you solve it for one platform then same will be reflected for other platforms too. I would suggest you to solve it for your primary OS i.e Linux.
