3rd Party Software

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!

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.

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.

Hey Can you help me how to enable the MSVC compiler , I couldnt choose it.

I found out while replying to your response that I tried to install with qmake at location "C:/Qt/5.15.2/mingw81_64/bin". Instead I changed path variable of qmake to location "C:/Qt/5.15.2/android/lib". Now it compiled. Thank you for your help @SGaist . :D

@CutiUser said in Error "symbol lookup error", "undefined symbol: SSLv3_client_method" using libQtNetwork.so.4:

I guess I can't get openssl v1.1.1 and v1.1.0 to work together...

That actually should work as version number is usually part of the library name or symbolic link.
I think Qt4 never supported LibSSL 1.1

@jsulm said in QT 5.12.11 add mng support:

Then please check the config.log file - probably something is missing (some library), so it is disabled.

Thank you for your advice. Finally , I found the disable configuration is in "/src/imageformats/configure.json" , change the mng condition to features.imageformatplugin ,this works.

@Chris-Kawa

The doc also says that you need to define FTD2XX_STATIC if you're using the static library.

I read this in the documentation, but tried to define into the source code. After you mentioned that I put

into the .pro file and that is works.

Thank you all for help.

Hello ramcho,

I have the same problem, did you find a solution to solve it ?

@ham13
I have no idea. But if QtRptProject is up to Qt6 it looks like it is being regularly maintained, can't you get in touch with them or find a forum to discover what the status of Zint and Qt4 is all about?

The relevant helper function is qt_mac_toQImage. Then QPixmap::fromImage can be used to get a QPixmap (example).

I built it with JDK 11 + NDK 21 + Qt 5.15.2 without any issue on Ubuntu 18 and 20.

Hi,

You need to link to the Cpputest libraries as well as explained in their documentation.

Hi and welcome to devnet,

You might want to consider moving to a more recent version of Qt because 5.0.1 is clearly outdated and had not cmake integrated yet.

Otherwise, you will need to either implement the Qt5 find module yourself. Or maybe KDE's ecm module might also help.

Hi,

If you are talking about the librairies that are available because embedded within Qt, you have the full details within the Qt sources. Search for the qt_attribution.json files.

You can also use qtattributionsscanner to grab the information.
