[Qt-interest] Problems Building QMYSQL plugin with MinGW

[John Eke]

Hi Guys,

I am trying to build QMYSQL on a MinGW/Windows platform and its failing (please see below for the log).

I installed MinGW, then installed the qt-win-opensource-mingw.exe package.

I also followed the instructions here: http://www.jiggerjuice.net/software/qt-sql-drivers.html

And I got stuck once I ran make.

Thanks

C:\qt\4.4.3\src\plugins\sqldrivers\mysql>qmake -o Makefile "INCLUDEPATH+=C:\MYSQL\MYSQL\INCLUDE"  "LIBS+=-LC:\MYSQL\MYSQL\LIB\OPT -lmysql"  mysql.pro
