@krist ok, as a step 1, why don't you open a console/terminal outside of QtCreator and try to launch the analogClock manually.
Make sure that works, before you try it from inside your own program!

@J-Hilk
helloyapps it's runnable
the step i use is$cd Qt5.13.2/Examples/Qt-5.13.2/gui/build-analogclock-Desktop_Qt_5_13_2_GCC_64bit-Debug/ enter $./analogclock@krist
Then you need to use something in your code which is actually the same as that, not what your screen shot has which is simply not the same!
Hint:/home/krist/Qt5.13.2/Examples/Qt-5.13.2/gui/build-analogclock-Desktop_Qt_5_13_2_GCC_64bit-Debug/analogclock.
Which you seem to have had at one point, and then changed to something wrong. -
yeah i have tried that and error is come up

OK, let's start from there! That path is correct, so let's not change off that!Now you have some issue of not finding the correct Qt version.
Are you Linux? Did you build your own Qt, or did you accept the one supplied with the distro? Have you installed more than one version of Qt at some point?
Ah, I see @sierdzio is pointing you at what you can look at.... I will leave you in his capable hands :)

ok
so right now the problem lies on my install qt right?
where should i source that environment?
is it to my workable analogclock?env.insert("TMPDIR", "C:\\MyApp\\temp"); // Add an environment variable@JonB
yeah i'm using linux and have 2 qt (one with ros plugin and the others only for qt)
tahnk you so much for your help!!! -

ok
so right now the problem lies on my install qt right?No. You simply have compiled AnalogClock using Qt incompatible with the one installed in the system. It's not an error, it's not a problem. Its actually quite common thing. Try double-cliking on your analogclock binary file - it will probably fail to run, too.
The proper way to solve it is to deploy AnalogClock so that it runs on your system without any changes to paths.

is it to my workable analogclock?env.insert("TMPDIR", "C:\\MyApp\\temp"); // Add an environment variableYou need to add
LD_LIBRARY_PATHand point it to your Qt 5.13.2 installation directory - where libraries are located. So something like:env.insert("LD_LIBRARY_PATH", "/home/krist/qt/Qt5.13.2/gcc_64/lib/");That needs to be fed to your QProcess so that the system can find proper Qt libraries when running Analog Clock example.
The reason why it runs from Qt Creator is that Qt Creator sets
LD_LIBRARY_PATHautomatically. -

No worries, happy coding :-)

@sierdzio
wow
thank you very much
I succed doing thatthank you for your hospitality and patience toward me
sory i'm so late to noticed it@krist
Hi there. I just wanted to say: if I was too harsh on you here and your other posting which I see you have now deleted, I would not want you to be put off asking questions in this forum! You are entitled to ask whatever you like, this is a friendly & helpful forum. I am just grumpy :)So don't be put off by me. Just please put some attention to detail in your work. When coding, you have to get every character correct, it's no use seeing something to try and then not copying the correct stuff and changing it to something else. That's all.
So no intention to upset you, best of luck. :)

hi JonB
thank you very much for your effort to help meafterall, it is my fault not pay attention enough because my dozen trials failed .
I will make sure next time to put the correct stuff for the question.thank you for your clarification
glad to hear that
