Installation and Deployment

@JKSH thanks It is install simply

Also a good way to force the auto comple update, is changing between compilers.

Hi, There's only QtWebKit and QtMultimedia that are affected. Because the binary packages are built for the officially older version of Linux supported. However, nothing stops you from rebuilding the modules against a more recent version of GStreamer provided that the backends of that old version supports it.

@SGaist Hi, of course you're right. I'll do so.

@SGaist said in vs2015 errors with (git) source code: Jom is already provided with Qt, somewhere under the Qt Creator folder. I like to compile QT from source. N.B. If I use windows QT installer i will get jom.exe I did execute the commands: jomd jomd install [image: 9897e6f8-c861-46e6-96b7-f7692fcd69ae.jpg] Now i get the Qt57MSV2015_32bit directory. Maybe i forgot "nmake install" in the nmake solution.

@Ratzz I'm not searching for services, only devices with QBluetoothDeviceDiscoveryAgent and there is no clear function.

Did you ever got it to run/compile maybe?

Just realized: @Discode said in Configuration OpenCV for iOS: -F $$PWD/ios You are using that option wrong, remove that space between the capital F and the $

So, an update from my side. I was unable to successfully include RTIMULib and therefore unable to build the module. Howerver,the RTIMULib is a c++ libary and the qtsensehat module is one as well, dooh. So I got the raw h and cpp files from here: RTIMULib QtSenseHat Changed the include path accordingly and added all files to my cross compile project. It now gets compiled each time when I make even the slightes change in my project, but it works :) I'll mark this as solved.

Only one module is the same as any other Qt project: qmake, make -(jnumber_of_cores_) * (3 +1), make install. I'd recommend an out of source build so it's easier to manage.

@sierdzio No problem bro, thanks for your help.

@SGaist I have successfully deployed onto a 32-bit Windows 7 VM, yet to see how real target machines do, but I'm pretty sure I'm good. Can you imagine? The key to revealing the mystery of missing dlls was NOT in Dependency Walker, but in Process Explorer! I don't want to say anything bad about DW, it just derailed the whole investigation. It has pointed to vcruntime140.dll, which as you said belong to MSVC++ 2015, when actually what was missing, at least from Windows 7 VM, was MSVC++ 2013.

@koahnig said in Qt does not find the .exe file: Can you freely switch forth and back with the left pane for compilation selection (debug/release) and the project is compiled as required? Yes. And I can also switch betwenn MSVC and MinGW.

@Aritz said in Setting up the Qt Mysql driver with Lampp in Ubuntu: sudo /opt/Qt5.6.3/5.6.3/Src/configure -opensource -confirm-license -qt-sql-mysql -no-xcb -v Why sudo?

@SGaist Thank you so much for clarification! I have managed to remove the dll from everywhere in the system except for the MySQL Connector C 6.1 folder in Program Files, which actually contains the dll that I've configured as a required library in .pro file. Now I'm struggling with a way to prevent database class from initializing before main(), which causes following errors to occur (copied from console output) QSqlDatabase: QMYSQL driver not loaded QSqlDatabase: available drivers: QSqlDatabase: an instance of QCoreApplication is required for loading driver plugins I highly suspect that it will be enough to get rid of database *db = new database (); in the beginning of database.cpp. I have fixed that and now I deploy successfully. Infinite thanks for your patience and insights

I figured it out. I created an account on DigitalOcean on an appache server and have everything working.
