@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.

[image: 7a72db15-9d25-4ea5-a2ae-00142f6c04cd.png] 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 DEFINES += FTD2XX_STATIC 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Hi and welcome to devnet, You might want to consider moving to a more recent version of Qt because 5.0.1 is clearly outdated and had not cmake integrated yet.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.

One thing about the static linking problem: it might be as simple as not having the libraries in the correct order.

Hi and welcome to devnet, Why are you stating that your application's language is C when using in fact C++ ? (That's what the .cpp extension hints to).

qwineventnotifier_p.h is a private header of Qt Core. Having a copy of it in your app is calling for problems, especially if the version of it doesn't match the exact version that Qt Core is built with. I assume qextserialport needs access to this private header; in this case, make sure that private headers are installed, and try to include the header from Qt.

I needed to switch my project to Qt5 and tried using setMedia and gst:pipeline but that wasn't working for me either. Right now, the pipeline below works as it connects to the camera I need it to and opens the gstreamer output. However, it opens it in a new window and not the Qt Video Widget I am using. I know autovideosink ignores the window overlay, but I tried other sinks and just got a black screen. How could I get this to work? I tried glimagesink which worked for the videotestsrc but it did not work for this. w->pipeline = gst_parse_launch( "udpsrc port=8000 ! application/x-rtp, encoding-name=H264, payload=109 ! rtph264depay ! h264parse ! queue ! avdec_h264 ! videoconvert ! autovideosink", NULL); /* [4] Set video overlay */ gst_video_overlay_set_window_handle(GST_VIDEO_OVERLAY(w->pipeline), w->getVideoWinID()); /* [5] Run the pipeline */ qDebug() << "------------------------------ Starting pipeline ------------------------------"; GstStateChangeReturn sret = gst_element_set_state(w->pipeline, GST_STATE_PLAYING); if (sret == GST_STATE_CHANGE_FAILURE) { gst_element_set_state(w->pipeline, GST_STATE_NULL); gst_object_unref(w->pipeline); }
