====== Build IBASE sql driver (linux) ======

[[http://doc.qt.io/qt-5/sql-driver.html#qibase-for-borland-interbase|source]]

Prior install firebird to ''/opt/firebird'' from [[http://www.firebirdsql.org/en/downloads/|here]].
  cd $QTDIR/qtbase/src/plugins/sqldrivers/ibase
  $QTDIR/qtbase/bin/qmake "INCLUDEPATH+=/opt/firebird/include" "LIBS+=-L/opt/firebird/lib -lfbclient" ibase.pro
  make
  

----

Note: if there is an error like: ''/usr/bin/ld.gold: error: cannot find -lgds'', search for ''libgds*'' in ''/usr'' and add it to qmake command. Suppose it was found in ''/usr/lib64'':
  qmake "INCLUDEPATH+=/opt/firebird/include" "LIBS+=-L/opt/firebird/lib -L/usr/lib64 -lfbclient" ibase.pro
