In ubuntu 18.04, I have an application that runs perfectly when executed by QTCreator. But when I need to deploy it to generate the installer, the app crashes without leaving a message. These are the steps I execute:
- I run the application through QTCreator
- I go to the build folder and deploy it with the command:
sudo /home/vboxuser/Downloads/linuxdeployqt-continuous-x86_64.AppImage MyApplication -verbose -qmldir=/home/vboxuser/Downloads/signer-css/qml -appimage
- I try to run my application with
sudo ./MyApplication and it crashes
- From the previous and subsequent logs I identified that the program crashes after executing the following line in c++ db =
QSqlDatabase::addDatabase("QSQLITE");
- I don't understand this, since I have the sqlite lib inside the
plugins/sqldrivers folder in the build directory.
I tried to put libqsqlite.so in the root folder.
I tried to put libqsqlite.so in the folder of an installer made with QTIntallerFramework
I tried to do debug and release builds
I tried to make an installer without doing the deploy
They all give the same error.
Does anyone have an idea of what I can do to get the application to run? I don't believe it's a code error, since this same snippet in C++ works for Windows, iOS, Mac and Android.
