I'm trying to connect to SQL Server database on ubuntu in Qt and need to install ODBC driver.
I did what document had told me to do here. And installed unixOBDC from here into /usr/local/unixODBC then running these commands
cd ~/Qt5.7.0/5.7/Src/qtbase/src/plugins/sqldrivers/odbc
qmake "INCLUDEPATH+=/usr/local/unixODBC/include" "LIBS+=-L/usr/local/unixODBC/lib -lodbc"
make
Which resulted in syntax error in couple of the sources 
This is what i get if i run my code at the moment
QSqlDatabase: QODBC driver not loaded
QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QPSQL QPSQL7
What am i missing?
