Installation and Deployment

@mourke said : They're dynamically linked libraries so they'd only be loaded once the code is called correct? No. The function pointers are resolved when your module is loaded. That's when you're getting that error. What you can do is put that troublesome part into another dll and load it dynamically (e.g. using QLibrary) only on Windows versions that support it.

Thanks man... Still don't decide which installation tool to use... may be some kind of wizard.. Thanks.

It's the first thing that gets built however, you are currently making things more complicated than necessary. You should just build the plugin using your already installed Qt rather than the full thing.

@condo4 said in Qt WebGL Streaming without GPU: I find the solution myself. great and thank you for sharing it. please don't forget to mark this post as solved then!

The qmldir option is to point the tool to your qml sources, if you use any, so that the corresponding dependencies are also deployed.

@mcleary You are correct and updating BIOS solved the problem. Thanks you so much!

Hi koahning, I've had a similar problem. Maybe my bugreport helps: https://bugreports.qt.io/browse/QTIFW-1003 After installing notepad++ and assigning ".vbs" extension to it, windows wasn't able to execute ".vbs" scripts anymore. Resetting the assignment in the regedit (HKEY_CLASSES_ROOT.vbs to "VBSFile") solves this issue. Maybe this solves your issue, too. Regards Jazzco

Hi, and welcome! @Yalimyulad said in Help with ./configure: Hello there I am trying to create the correct ./configure for compiling qt-everywhere-opensource-src-4.8.7 using Ubuntu 16.04 64bit Could you provide more details on your goals? Why compile from source instead of using a pre-compiled version? Why use Qt 4.8 (which reached end-of-life in 2015) instead of Qt 5? What device (and what OS) are you targetting? In case it helps, here is a very detailed step-by-step tutorial that shows you how to build Qt 5.12.7 on different models of Raspberry Pi: https://www.tal.org/tutorials/building-qt-512-raspberry-pi

@Christian-Ehrlicher This is true... (I swear, I didn't see your post before to find this solution. So I just add those commands I used for those it coul'd help : cd ~/Qt/5.12.7/Src sh configure -sql-mysql Choose youre version Type 'c' if you want to use the Commercial Edition. Type 'o' if you want to use the Open Source Edition. Which edition of Qt do you want to use? o Accept license Type 'L' to view the GNU Lesser General Public License version 3 (LGPLv3). Type 'G' to view the GNU General Public License version 2 (GPLv2). Type 'y' to accept this license offer. Type 'n' to decline this license offer. Do you accept the terms of either license? y And be sure to see this line MySql .................................. yes cd qtbase/src/plugins/sqldrivers/mysql/ /home/smv/Qt/5.12.7/gcc_64/bin/qmake "INCLUDEPATH+=/usr/include/mysql" "LIBS+=-L/usr/lib/mysql -lmysqlclient_r" mysql.pro make install That's it :) Thanks everyone for your great help.

@fantasyhpu Certainly is the offline installer an option. However, this is also eating HD space until you can remove when you have the proper Qt libs installed.

Hi and welcome to devnet, You're image is not visible.

@aha_1980 Hi, your answer is very clear, I understand. Thank you.

I've just tried once more resync the /usr/lib. ... and it failed immediately: 2020/02/14 12:25:34 [7746] receiving file list 2020/02/14 12:25:34 [7749] rsync: send_files failed to open "/usr/lib/cups/backend/vnc": Permission denied (13) 2020/02/14 12:25:38 [7749] sent 5,485 bytes received 1,284,984 bytes 73,741.09 bytes/sec 2020/02/14 12:25:38 [7749] total size is 3,341,241,457 speedup is 2,589.17 2020/02/14 12:25:38 [7746] rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1668) [generator=3.1.2]

I'm running MacOS Mojave 10.14.5 and have Xcode 10.2 installed. The reason for the above error is due to the configure option -c++std c++11. Removing that constraint allowed the build to progress. I got two further build errors: In qtcanvas3d, which I was able to circumvent by skipping the module. In qtvirtualkeyboard, the hunspell include path incorrectly includes the hunspell subfolder since the header file refers to `hunspell/hunspell.h'. I hacked this by creating a subfolder and a symlink back to the header file in its original location. (See error details below.) With these workarounds, I was able to get a successful make using the following configuration: ../configure -qtlibinfix 5.14.1G -qtlibinfix-plugins -opensource -debug-and-release -developer-build -framework -pkg-config -nomake tests -skip qtandroidextras -skip qtwayland -skip qtwebchannel -skip qtwebengine -skip qtwebglplugin -skip qtwebview -skip qtwinextras -skip qtx11extras -skip qtcanvas3d Expecting make install to install into the default -prefix location, I was disappointed to find that /usr/local did not contain any new Qt folders; neither Qt-5.14.1 nor Qt-5.14.1G were there, nor were there any other new folders there that might have come from the build. I'll need to debug this issue, but since I haven't used qmake before, I'll need to get familair with its way of doing things first, including understanding .pro files. I am pleased to see that the significant outputs from my build are all marked with the suffix I asked for in the -qtlibinfix 5.14.1G -qtlibinfix-plugins configuration options. Hopefully this will make it easier to debug the qt_gui_cpp package in ROS Kinetic. What is nice is that the header I am having difficulties with in the ROS build compiled correctly in my Qt build. Thus I can be sure that until ROS builds, the error is in ROS not Qt.

@ClassroomAdmin said in Classroom Deployment of QT for multiple pcs and for all users (windows): I mean headless and login won't go hand in hand. You will most likely have to provide the login data as command line parameter or as file. So again, what's the point in all of it? As @jsulm said, we are fully with you and unsatisfied with this situation. But you have to put the pressure on The Qt Company, not on us. And you even provide a complete offline installer package, so why not make it usable for everyone. The offline installer will only be available for commercial customers in future. Regards

@Yalimyulad said in Post installing Qmake for new devices: Is it possible to somehow copy the Qmake I have built from raspberry pi to my desktop? Nothing is physically stopping you, but it won't work. qmake is created and specific to the Qt FrameWork/Compiler used for that framework. The compiler on your pi is not the same as the one you would use for cross compiling If you want to really cross compile for the Pi , you will have to jump through some loops. There are some guides out there for example this wiki entries https://wiki.qt.io/Raspberry_Pi_Beginners_Guide https://wiki.qt.io/RaspberryPi2EGLFS

@Namiruc said in Support for ARM Cortex A7: I use a VAR-SOM-6UL (imx6) board and I want to install QT Assuming such board is this one from Variscite (since you didn't provide details about it), you may want to look into its wiki.
