Static build for SQL plugin

SGaist

Are you sure the --with-includes and --with-libraries options are valid ? AFAIK it should be -I and -L when calling configure

AFAIK these two options used in Postgresql configure file while -l -L used for Qt.

Any way, I'll try to use -l & -L to se if they will affect or not.

I tried to use -l & -L as you mentioned above but I got this error message. It seems that --with-libraries & --with-includes are the correct options:

[code]mbnoimi@MBNOIMI-VBOX ~/postgresql-9.1.9
$ ./configure --without-zlib --with-openssl -lC:/OpenSSL-Win32/include -LC:/OpenSSL-Win32/lib/MinGW
configure: error: unrecognized option: -lC:/OpenSSL-Win32/include
Try `./configure --help' for more information.

mbnoimi@MBNOIMI-VBOX ~/postgresql-9.1.9[/code]

When configuring you have to let a space between -I/-L and the path

I got same result!

SGaist

Did you clean before trying with the space ?

I used "make confclean"

UPDATE: I got: error message:
[code]mbnoimi@MBNOIMI-VBOX ~/postgresql-9.1.9
$ make confclean
make: *** No rule to make target `confclean'. Stop.[/code]

Ok... I didn't realize you were trying to build postgresql... You should rather ask them how to do that

Finally I successfully built libpg (Postgresql client) with OpenSSL but now Qt itself gives me error message after calling ming32-make as following:

It crystal clear that this issue related to unknown path although I passed the paths during configure step as following:

[code]configure -no-warnings-are-errors -qt-pcre -qt-libpng -ltcg -release -developer-build -static -qt-sql-sqlite -qt-sql-psql -qt-zlib -qt-libjpeg -opengl desktop -nomake examples -nomake tests -I C:/Postgresql-static/postgresql-9.1.9/src/include -L C:/Postgresql-static/postgresql-9.1.9/src/interfaces/libpq[/code]

ls of libpq folder is:
[code]Postgresql-static/postgresql-9.1.9/src/interfaces/libpq > ls *.h
fe-auth.h libpq-events.h libpq-fe.h libpq-int.h pqexpbuffer.h pqsignal.h win32.h[/code]

NOTE: libpq-fe.h already exists in C:/Postgresql-static/postgresql-9.1.9/src/interfaces/libpq !!!

I fixed the above issue and built Qt successfully by using the following configurations:

[code]configure -no-warnings-are-errors -qt-pcre -qt-libpng -ltcg -release -developer-build -static -qt-sql-sqlite -qt-sql-psql -qt-zlib -qt-libjpeg -opengl desktop -nomake examples -nomake tests -I C:/postgresql-9.1.9/src/include -L C:/postgresql-9.1.9/src/interfaces/libpq -I C:/postgresql-9.1.9/src/interfaces/libpq[/code]

But as soon as I call any SQL class I get linking error although I successfully built Qt and Postgresql by MinGW!
http://pastebin.com/2e8pqnmM

I used the following project to test SQL connectivity:

test.pro
[code]QT += core gui sql

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = test
TEMPLATE = app

SOURCES += main.cpp
mainwindow.cpp

HEADERS += mainwindow.h

FORMS += mainwindow.ui

QMAKE_LFLAGS += -static -static-libgcc -static-libstdc++ -lpthread

LIBS += -LC:/postgresql-9.1.9/src/interfaces/libpq -lpq
[/code]

main.cpp
[code]QSqlDatabase db = QSqlDatabase::addDatabase("QPSQL");
db.setHostName("192.168.0.74");
db.setPort(5432);
db.setDatabaseName("testDB");
db.setUserName("postgres");
db.setPassword("pass");
if (!db.open())
qDebug() << "Unable to connect!";
else
qDebug() << "connected.";[/code]

BTW, libpq.a and libpq.dll are exists in in C:\postgresql-9.1.9\src\interfaces\libpq

raven-worx

i'm not sure, but i t may be that you need to do this in your PRO file:
LIBS += -LC:/postgresql-9.1.9/src/interfaces/libpq -llibpq

ok i was wrong then.

According to "this post":http://www.postgresql.org/message-id/Pine.LNX.4.30.0108241344260.677-100000@peter.localdomain you need -lpq, what you already had tried. So it seem this was correct. So the problem needs to be somewhere else.

What do you suggest? I emptied my pockets :)

mbnoimi

Sorry guys but I'm still stuck with this issue.

I successfully built Postgresql's client by MinGW and Qt for with static options for enabling Postgresql but I Qt failed in linking the libraries as mentioned in my post https://qt-project.org/forums/viewreply/143908/

May you give me a hand of help?

SGaist

Did you also add
@QTPLUGIN += qsqlmysql@
to your pro file ?
and
@Q_IMPORT_PLUGIN( qsqlmysql )@
to your main.cpp ?

EDIT: corrected macro

mbnoimi

After adding the lines you've mentioned I got this error:
[code]..\test\main.cpp:5:17: error: expected constructor, destructor, or type conversion before '(' token
QT_IMPORT_PLUGIN( qsqlpsql )[/code]

BTW, I never find any *.dll or *.a inside Qt folder where I built it statically!!! so I wonder how these line will link qsqlpsql?

SGaist

Did you build Qt with qt-sql-psql ? (Not -plugin-sql-psql)

mbnoimi

[quote author="SGaist" date="1380279497"]Did you build Qt with qt-sql-psql ? (Not -plugin-sql-psql)[/quote]

Yes; I built using:
[code]configure -no-warnings-are-errors -qt-pcre -qt-libpng -ltcg -release -developer-build -static -qt-sql-sqlite -qt-sql-psql -qt-zlib -qt-libjpeg -opengl desktop -nomake examples -nomake tests -I C:/postgresql-9.1.9/src/include -L C:/postgresql-9.1.9/src/interfaces/libpq -I C:/postgresql-9.1.9/src/interfaces/libpq[/code]
