I created a QT app, released it, there was a new folder of release, I opened the release folder and copied Process_Orders exe file and pasted in a newly created folder called(deploy-with-linuxdeployqt)

What is this folder?
I don't understand what you are doing.
Please read https://github.com/probonopd/linuxdeployqt/blob/master/README.md

I have already gone through the link you sent. I have gone through many other websites and tutorials.

I am going to rephrase all the steps I followed

In qt creator, I created an app, it ran perfectly, I selected release mode, and built it again,
This folder was created after I built the release mode (build-Process_Orders-Desktop_Qt_5_9_1_GCC_64bit-Release)
In this release folder, I had a file with the name (Process_Orders)
I copied this Process_Orders file,
created a new folder in this directory (/Documents/cpp). Named new folder as (deploy-with-linuxdeployqt)
Pasted (Process_Orders) file in (deploy-with-linuxdeployqt) along with an icon image and .desktop file
Downloaded linuxdeployqt-7-x86_64.AppImage from github(In Downloads)
Executed this command in terminal after changing directory to downloads (./linuxdeployqt-7-x86_64.AppImage ~/Documents/cpp/deploy-with-linuxdeployqt/Process_Orders -unsupported-allow-new-glibc)

Where did I make mistake?

What mistake do you mean?
I only see some warnings.
What looks wrong is "/home/kaleem/anaconda3/plugins/platformthemes/libqgtk2.so".
Do you have anything related to /home/kaleem/anaconda3 in your PATH?

./linuxdeployqt-7-x86_64.AppImage ~/Documents/cpp/deploy-with-linuxdeployqt/Process_Orders -unsupported-allow-new-glibc
This command was supposed to create an exe or sh file in the Downloads folder, but it didn't. why?do I need to do something else as well? some other command to execute on the terminal? to get what I need.
Remember, I need an exe or sh or whatever file, that runs on a double click and does according to my programming

I followed this article (https://medium.com/swlh/how-to-deploy-your-qt-applications-to-linux-operating-system-with-linuxdeployqt-3c004a43c67a)

You need to pass -appimage flag to linuxdeployqt. This way it will generate an AppImage executable with everything bundled inside.

Thanks for (-appimage) suggestion, yes it worked, It created (myfirst-x86_64.AppImage), but when I double click it, or right_click->run , it does not do anything, no Window pops up, nothing happens
How should I proceed now? @sierdzio?

Run it from terminal and observe the output for any warnings or errors.

@sierdzio
i ran it with (./myfirst-x86_64.AppImage) on terminal
it gave following output
./myfirst-x86_64.AppImage: symbol lookup error: ./myfirst-x86_64.AppImage: undefined symbol: _ZdlPvm, version Qt_5

Well, something is wrong :D It's missing some library. Try running ldd on application executable.

Hi, I also had a problem after using linuxdeployqt, I run the example of hello_speak to transform text to speech, but I got a warning No text-to-speech plug-ins were found; therefore, my app also does not voice. Please help me. Thanks
