how to add library(qmqtt.h) in qmqtt client for windows
-
@shravani
Again: you need the DLL file to be able to execute your app. Where is qmqtt.dll (or libqmqtt.dll)? -
-
@shravani The DLL must be in a directory where the operating system is looking for shared libraries when loading an app. Fastest way is to copy it to the build directory of your app (where your executable is).

Hi,
You can't start an application like that from explorer, you first have to follow the same steps you would before deploying your application on another computer.

@SGaist
In Qt creator also I'm getting same error after adding ucrtbased.dll to debug folder.
i tried executing examples given in qt but getting same error.
recently i installed this qt 5.8.1 msvc2015 new version because in qt 5.0 it(mqtt) is not working.

@shravani Which DLLs exactly did you copy and from where? No need to copy ucrtbased.dll when starting from QtCreator.

@jsulm
while running from qt creator(DLL not found)
so i checked from outside qt to see which dll missing.so i added that@shravani Running outside from QtCreator is different. You actually only need to copy your qmqtt.dll if you want to run from QtCreator. If you want to run outside of QtCreator you need to deploy your app as @SGaist already said. In one of my previous posts in this thread I posted a link to a side where you can read how to deploy your app on Windows.

i copied qmqtt.dll but still got that error (DLL not found).do i need to add anything else? -
@shravani When you built qmqtt.dll were any other DLLs created in the same directory? Did you try to find out what is missing using http://www.dependencywalker.com ?

@shravani Then you should deploy your app using Qt Windows Deployment Tool and see which DLL will end up in your deployment directory.
