Unable to find .exe file in my project

[Wasee]

Dear all;
I am using Qt5 on Ubuntu 18.04 operating system. I design widget application in qt5 and build successfully. But in my build directory I did not see .exe of my designed application.Please guide me how I can find my .exe file.
Thanks in advance!

@Wasee
Linux does not use any .exe extension. Executable is in the build output directory (along with all the .o files too).

@JonB
Thanks for your great reply! But the file I found not running in startup why?

Because dependencies/shared libraries where not found, perhaps?

What do you do to try to run it, what does/does not happen?

@JonB
I found these files in build directory but when I run it in start up its produces errors of binaries etc.

@KroMignon Hi;
Thanks for your valuable reply! In my ubuntu 18.04 startup session my executable working fine where I build the application. But when I put that executable file into another linux system startup session then its not working correctly and not opening the file: Error "cannot execute binary file: Exec format error.

Thanks in advance

@Wasee You have to deploy your app first. See https://doc.qt.io/qt-5/linux-deployment.html "Creating the Application Package".
"Error "cannot execute binary file: Exec format error" - this suggests that the other machine has a different architecture. Please provide more information: what CPU architecture is first machine and which is second (c86, x86_64, ARM, ...)?

Okay, so your binary is working on the build machine but not on another one.
Linux != Linux, are you sure:

• CPU type are same on booth?
• OS version (32 bit / 64 bit) is same?
• all required packages are installed?

You could try to check if all dependencies are met for the executable with ldd.

For example, on my test machine, I got:
