QT5.6 + OSX: QOCI driver not loaded but available

zolotukhin

OSX: 10.11.4
QT: 5.6
Oracle: 11.2 64-bit

Trying to create simple application with Oracle connection. libqsqloci is created successfully (thanks for manual), libqsqloci.dylib is locating in clang_64/plugins/sqldrivers

.pro file:

QT += core gui sql

.cpp file:

#include <QSqlDatabase>

...

QSqlDatabase db = QSqlDatabase::addDatabase("QOCI");

Application starts... and I see error:

QSqlDatabase: QOCI driver not loaded
QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QOCI QOCI8 QODBC QODBC3 QPSQL QPSQL7

I not found anything working solution, so decide to ask here. Thank you

Hi and welcome to devnet,

Do you have the OCI libraries installed on your system ? More information about them here

@SGaist Thanks for reply. OCI libraries is installed, tnsnames is created, sqlplus is working successfully.

My zshrc:
export PATH=/usr/local/bin:$PATH
export ORACLE_HOME=/Volumes/Data/Oracle/instantclient_11_2
export LD_LIBRARY_PATH=$ORACLE_HOME
export DYLD_LIBRARY_PATH=$ORACLE_HOME
export TNS_ADMIN=$ORACLE_HOME/network/admin
export OCI_HOME=$ORACLE_HOME
export OCI_INCLUDE_DIR=$ORACLE_HOME/sdk/include
export OCI_VERSION=11
export NLS_LANG=AMERICAN_AMERICA.CL8MSWIN1251
export PATH=$ORACLE_HOME:$PATH
export CLASSPATH=$ORACLE_HOME:$PATH

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME:/Volumes/Data/Qt5.6.0/5.6/clang_64/plugins/sqldrivers/

Then you should run otool -L on the Qt OCI plugin to see if it is missing something.

By the way, there's no need to put Qt's plugins folder in the LD_LIBRARY_PATH.

@SGaist

I am new to QT, Can you please tell me how to run otool -L

SGaist

Hi,

otool has nothing to do with Qt. It's a macOS tool. Calling otool in your command prompt would have shown you have to use it faster than waiting on an answer here.

otool -L /path/to/library_or_executable
