I am trying to create a executable file on Linux something like maintenance tool (see snap)
I am using Template as app for my qt project like this :
#config
CONFIG += c++11
#template
TEMPLATE = appThe file getting created is a shared library. I don't know why. Please assist.

@SGaist I am not getting any errors. Its just that I want an executable build instead of building an SO file from qt creator. I have set the Template to app in PRO file but still doesn't work.

Can you please post the output from "file YOUR_APP_EXE"? It will tell you what it really is.
It could be that the file manager shows the wrong type for whatever reason.The reason why it does not start from explorer is most probably because you did not deploy it properly. See https://doc.qt.io/qt-5/linux-deployment.html
QtCreator prepares the environment before it starts the app, so all Qt libs/plug-ins can be found. But when you start manually from file manager or terminal you have to prepare the environment or create a package (deploy the app). -

The link I posted before.
The file output looks fine, so please take a look at the link and deploy your app before starting it. -

@jineshmehta Can you please post the whole pro file as text?
"And I should get a executable but no luck. :(" - I'm sure you get an executable (or is compiling failing? If so please post the errors), as it is working from QtCreator. You're hunting the wrong issue. And you did NOT follow all instructions. You stop after building, but you have to deploy. Please take a look and follow the chapter "Creating the Application Package" in the link I posted. -

I don't get it: if it works it is already an executable.
Or do you mean you want to have everything in one single executable? -

@jineshmehta Sorry, I don't understand what you mean. plugandpaint is your executable, so what do you want to change?
