@cjacquel2021 Suggest you search this forum, or the web, for send mail or send email for various suggestions. https://forum.qt.io/topic/102082/is-there-anyway-to-send-email-to-someone-in-qt/2 mist be a start.

@sneha-ashok said in libQtcore so.5: The libraries files of qt is not been picked by my Yocto setup only the libQTcore so.5 libraries is not been. Please review this sentence. We realise English may not be your first language, but it does not make sense as it is. If the error message really reads libQTcore so.5 (did you copy & paste it or just type it in?) then that is incorrectly spelt somewhere you have asked for it.

@Imeshsps Turns out you have to add -DQT_FEATURE_alsa=ON to make experimental feature ON.

@Imeshsps This was solved by reading the CAN messages on a seperate process and pass only necessary data to Qt through a Named pipe. Seems like large number of signals occur from CAN messages overflow the Qt signal space.

@piervalli Awesome, thank you! I will move ahead with TLS as I expected. Thanks for your assistance earlier as well!

Depending on your project and constraints, you will have to use an older version of Qt that supports that outdated version of Visual Studio. I would first check with LDRA to ensure with them that their tools can be used with more recent versions of Visual Studio.

@JonB Exactly, downloaded libusb version for mingw 64 and now it's working. Thank u guys for support.

Did you manage to compile qwt for iOS?

@JoeCFD I was able to find an answer to this question by doing this: find_package(PkgConfig REQUIRED) pkg_check_modules(ZBar REQUIRED IMPORTED_TARGET zbar) target_link_libraries(camera PUBLIC PkgConfig::ZBar) Since I anyway had pkg-config, I found that package and then zbar using that package and then linked it with the libraries.

This thread on the OpenFrameworks forum might help.

I found the problems: I forgot to include the libraries hdf5_hl hdf5_hl_cpp and hdf5_hl I had 2 versions of hdf5 installed: 12.2 and 14.0 I had to uninstall 12.2. Now, it seems to work. Thanks to all.

Was able to resolve it by adding LIBS += -lWindowsApp to *.pro file. Thread can be closed.

@SGaist Great Thank you this, I know that qt has its own MQTT module just I had already developed my code for MQTT using the mosquitto library before I knew I was going to be making a GUI using QT.

Fixed the issue. Turns out it was something with my laptop. I had gotten a secondary laptop that had the same environment, all Windows 10, downloaded the NIDAQmx software, and it connected to my Qt application perfectly fine. Very odd, unsure why this happened. I went about the installation process the same on both laptops. I hope nobody ever has to go through this issue again, but if you are, might want to try on a new laptop..Worked for me!

@Schloern To run ros packages, it is necessary to run the setup.bash file, for example, the setup.bash file should be run in the linux operating system. source /opt/ros/humble/setup.bash Start the QT Creator application in the terminal where you enter the setup.bash controls. step 1: Open terminal and enter "source /opt/ros/humble/setup.bash" command. Note: this is ros humble enter your own setup.bash file step 2: Open the QT Creator application from the terminal you included ros2 step 3: If you want to work simultaneously with ROS, use threads.

@Neptunus I would expect these to be resolved by linking with kernel32.lib? Compare the linker lines generated from VS vs Creator? I don't know what Win32_Interop.lib is.
