    I recently ran into an issue with mysql (mariadb) in a linux environment - apparently, the 5.3.1 release ties to an older version of mysql that my system no longer supports (apparently, qt-5.3.1-release wants version .16, while my system uses .18). If you have this problem, an ldd of /path/to/qt5/plugins/sqldrivers/libqsqlmysql.so should show that it can't find your mysql libs. To fix this, go into the source directory at qtbase/src/plugins/sqldrivers/mysql, run qmake (specifically for 5.3.1, not the system qmake), and then make install.

          Hello, I'm new to QT and I have installed QT from this installer on Windows 7 64bit:
          qt-opensource-windows-x86-1.6.0-5-online.exe

          but I don't see the src folder and I don't have a QT Sdk. How can I install the sdk? thanks.

            Hi and welcome to devnet,

            You need to first install the sources. Use the installer for that

              OK now I have installed the sources (maybe) and I have a folder called Src, this is my path: C:\Qt\5.3\Src.

              I try to follow the tutorial but in my situation when prompt "reimp libmysql.dll" I receive this message:

              "reimp: libmysql.dll: invalid or corrupt import library"

              but if prompt "reimp libmysql.lib" seems to work.

                  Either install the Direct X SDK or pass -opengl desktop to configure

                    I'm sorry and frustrated but
                    but unfortunately for me it is the first time with C++ and QT.
                    I lunch configure:

                    configure.exe -opengl desktop

                    and the result is:

                      Just one question, do you only need to build the MySQL plugin ? If so, there's no need to rebuild Qt completely

                        This is the first time for me with C++ and QT so for me it's all new and I do not know what are the requirements needed to achieve my goal.
                        I want to make a windows application that keep some signal from a RFID antenna attached to notebook from serial and store data in a mysql database.
                        To start I want only to connect to mysql database and read a table data.

                        So I guess I need only mysql plugin.

                          Then just compile the MySQL plugin like described in the documentation, no need to rebuild everything.

                                          Each platform has it's own gotchas but the *nix variants are generally more easy to deal with when it comes to dependencies like MySQL

                                          You're welcome :)
