    @orzel1244 please be aware that the image you posted says "QSQLITE driver not loaded" Are you sure you're effectively using a MySQL connection/DB as backend?

      I use linuxdeploytool and it says I'm missing libmysqlclient.so.18

      It looks like you're referencing MySQL somehow which is not really needed, and you're missing to reference/include Sqlite which you indeed want to use.

        If you are actually using this linuxdeployqt tool, please take a look at this issue.

            Hi,

            You likely have have MySQL version 20 if you have a recent Linux distribution.

            But since you are not using MySQL with your application. Why not just ignore that warning ?

            What do you get if you call ldd on the Qt SQLite plugin ?

                Because the warning doesn't allow me to access my sqlite database

                ldd on the plugin gives me:

                  Looks like there's a missing feature to disable unused SQL plugins for linuxdeployqt.

                  Then you should consider re-building the MySQL plugin against the version you installed on your system.

                    I'm still getting error while trying to compile Qt from sources, I think it's too hard for me and it's better to use other lib for database :/

                      Then as a quick work around:

                      • Make a copy your sqldrivers folder.
                      • Remove all plugins in the original folder except the one you use.
                      • Re-run linuxdeployqt

                        You want me to copy sqldrivers from Qt dir to the application dir or what? I'm sorry I don't understand what you meant

                          No, make a copy of the sqldrivers folder from the Qt installation you used to build your application. So you keep all the original files safe. Then in the original folder from your Qt installation, delete all the non SQLite related files. Doing so, linuxdeployqt will only deploy the SQLite driver. Once your done, just delete the modified sqldrivers folder and put back the copy you made just before.

                              libmimerapi.so is not a plug-in, it's a library you have to install. Search for the package in your Linux distribution which installs it.

                                ... Or simply delete the Qt mimer sql plug in if it is not needed.
