[shravani]

@jsulm
while running from qt creator(DLL not found)

so i checked from outside qt to see which dll missing.so i added that

[jsulm]

@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.

@jsulm
i copied qmqtt.dll but still got that error (DLL not found).do i need to add anything else?

[jsulm]

@shravani After adding qmqtt.dll which DLL is missing?

[shravani]

@jsulm
it was just showing the above error.i cannot find which dll is missing

[jsulm]

@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]

@jsulm
only 2 dll files(qmqtt.dll,qmqttd.dll) created and i copied both.

[jsulm]

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

[jsulm]

@shravani Should be possible if you have Internet connection and access rights.

[shravani]

@jsulm
internet connection is there. access rights?
do i need to change anything in qt program?

[jsulm]

@shravani I never used it but I guess you need access rights to connect? You should ask the people providing those brokers.

[shravani]

@jsulm
do you know any broker that can be connected to qt application through internet?

[jsulm]

@shravani I guess any mqtt broker?
