Static build PostgreSQL in app

Artmetic

I have problem to static link my postgress plugin to app. The output compilation fault is that:

undefined reference to `qt_static_plugin_qsqlpsql()'
./release\managament_plugin_import.o:managament_plugin_import.cpp:(.text.startup+0x26): undefined reference to `qt_static_plugin_QPSQLDriverPlugin()'

This is my pro file:

QT += core gui sql
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

#CONFIG += plugin static

CONFIG += c++11 static
QTPLUGIN += qsqlpsql

#include(psql/qsql_psql.pri)
#PLUGIN_TYPE = sqldrivers
#load(qt_plugin)
DEFINES += HAVE_STRUCT_TIMESPEC
#INCLUDEPATH += C:\PostgreSQL\9.2\include
#DEFINES += STATIC QT_STATIC
#DEFINES += QT_STATICPLUGIN
#PRE_TARGETDEPS += C:\Qt\5.5\Src\qtbase\plugins\sqldrivers\libpq.dll
#LIBS += -L$$PWD\sqldrivers\qsqlpsql.dll
#LIBS += -LC:\Qt\5.5\Src\qtbase\plugins\sqldrivers\libqsqlpsql.a
#PRE_TARGETDEPS += C:\Qt\5.5\Src\qtbase\plugins\sqldrivers\libpq.dll
#QMAKE_LFLAGS += -static -static-libgcc -static-libstdc++ -lpthread

as you see I try many ways to do this. I don know what is wrong because I added to my main.cpp:

#include <QSqlDriverPlugin>
#include <QtCore/QtPlugin> 

Q_IMPORT_PLUGIN(qsqlpsql)

I don't know should I add -qt-sql-<driver> and how. because If I add to makefile.release nothing change?
Please help, I try do this cople days and nothing change.

Hi,

Did you compile Qt statically ?

Artmetic

Yes I compile qt staticly.

Did you build the PostgreSQL plugin as part of your build ?
If not then follow the documentation about QtSQL plugin build.

Otherwise, rebuild Qt and include the driver directly but you'll have to do it from a clean build.
