Compiling IBASE sql driver for Qt 5.3 on openSUSE 13.1

For this you will need to have firebird development package already installed on the system and also Qt 5.3. First, we go to the plugin source location:

cd <QtPath>/5.3/Src/qtbase/src/plugins/sqldrivers/ibase

Unless we edit on he of the project includes, the build will fail, so let’s edit this. (I use joe, use whatever you like):

joe ../../../sql/drivers/ibase/qsql_ibase.pri

Once file is open for editing, find the following line:

!contains(LIBS, .*gds.*):!contains(LIBS, .*libfb.*):LIBS += -lgds

and change it to this:

!contains(LIBS, .*gds.*):!contains(LIBS, .*lfb.*):LIBS += -lgds

(the reason of changing this is that you specify later LIBS+=-lfbclient, so there will be no lib in front of fbclient)

All set, build and install:

<QtPath>/Qt/5.3/<platform>/bin/qmake "INCLUDEPATH=<firebird header files>" "LIBS+=-lfbclient"
 make install

On my system, by default the <firebird header files> are located in the /usr/include/firebird folder.

Code to test the database connectivity:

QSqlDatabase db = QSqlDatabase::addDatabase(“QIBASE”);
db.setHostName(“your host here”);
db.setDatabaseName(“your database file (with path) here”);
db.setUserName(“your username”);
db.setPassword(“your password”);
bool ok =;

if (!ok) {
QSqlError err = db.lastError();
qDebug()<<“woopsie error opening database:”<<err.text();
} else {
qDebug()<<“Database successfully opened.”;


Happy coding.
