Installing ODBC driver on Ubuntu getting syntax error after running "make"

  • I'm trying to install ODBC driver to access a SQL Server Database.. After following the docs here and installing unixODBC from here

    after running

    cd $QTDIR/src/plugins/sqldrivers/odbc
    qmake "INCLUDEPATH+=/usr/local/unixODBC/include" "LIBS+=-L/usr/local/unixODBC/lib -lodbc"

    I got a lot of syntax errors

    and still getting

    QSqlDatabase: QODBC driver not loaded
    QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QPSQL QPSQL7 

    when running my code..

    Hi and welcome to devnet,

    You are likely using the wrong qmake.

    Use the full path to your Qt 5.7 qmake.

  • Hi. thanks for the welcome and answer.. i was about to install Windows tbh

    and wow. apparently that was the issue now it compiled.. after that i was getting the same error

    QSqlDatabase: QODBC driver not loaded
    QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QPSQL QPSQL7

    but managed to fix it by copy and pasting the compiled "libqsqlodbc.so" file to




    but i am failing to open my connection. how can make sure it's working ?

    The open method returns a boolean value so you should check that and if false is returned then you should print the content returned by lastError.

  • it says

    [unixODBC][Driver Manager]Can't open lib 'SQL Server' : file not found QODBC3: Unable to connect

  • Lifetime Qt Champion

    What is your connection string ?

  • DRIVER={SQL Server};Server=localhost\SQLEXPRESS;Database=honar;Uid=SA;Pwd=*******;

    and i'm using
    Microsoft SQL Server vNext (CTP1.1) - (X64)

    Did you check unixODBC without the GUI ?

  • Dude you are awesome.. that error is solved but yet exist another one..
