Run SETUP.EXE and choose "Custom Install". Install the "Libs & Include Files" Module. Build the plugin as follows (here it is assumed that MySQL is installed in C:\MYSQL): cd %QTDIR%\src\plugins\sqldrivers\mysql qmake -o Makefile "INCLUDEPATH+=C:\MYSQL\INCLUDE" "LIBS+=C:\MYSQL\LIB\OPT\LIBMYSQL.LIB " mysql.pro nmake If you are not using a Microsoft compiler, replace nmake with make in the line above.все сделал как пишет но не помогло.Что делать ?
