@Sergey_85 Did you install Qt for Android?

[Sergey_85]

@jsulm Yes

[jsulm]

@Sergey_85 said in Mqtt:

-DCMAKE_PREFIX_PATH=/home/ph/opt/Qt/6.8.0/gcc_64

This doesn't look like a path to Qt for Android

[Sergey_85]

@jsulm I tried -DCMAKE_PREFIX_PATH=/home/ph/opt/Qt/6.8.1/android_arm64_v8a

[jsulm]

@Sergey_85 And what happened? Does /home/ph/opt/Qt/6.8.0/gcc_64 contain Qt6Config.cmake or qt6-config.cmake like CMake requested in the error message?

[Sergey_85]

@jsulm yes, the Qt6Config.cmake file is also in the folder
/home/ph/opt/Qt/6.8.1/android_arm64_v8a/lib/cmake/Qt6/Qt6Config.cmake

I haven't compiled from sources before, what's in the kit was enough for me, so I apologize if I'm asking something wrong or providing incomplete information, I'm confused(

[jsulm]

@Sergey_85 The I think it should be

-DCMAKE_PREFIX_PATH=/home/ph/opt/Qt/6.8.1/android_arm64_v8a/lib/cmake/Qt6

[Sergey_85]

@jsulm ```
cmake ..
-DCMAKE_PREFIX_PATH=/home/ph/opt/Qt/6.8.1/android_arm64_v8a/lib/cmake/Qt6

@Sergey_85 Try with a clean build folder (best to create a fresh one)

[Sergey_85]

@jsulm nothing has changed

[jsulm]

@Sergey_85 said in Mqtt:

nothing has changed

Do you mean same error?

[Sergey_85]

@jsulm Yes, I have the same error

[jsulm]

@Sergey_85 Not sure why it is not working try:

export Qt6_DIR=/home/ph/opt/Qt/6.8.1/android_arm64_v8a/lib/cmake/Qt6

before calling cmake.

[Sergey_85]

@jsulm
everything is the same, under gcc-64 everything was assembled without problems and works, I don’t understand why there are such difficulties here

Hi,
"http://code.qt.io" this is not opening, Is there any other way to use QTMQTT??

[SGaist]

@kiru hi and welcome to devnet,

It's seems to be working here at the time of writing.

If it's still not, you can use the GitHub mirror.
