Static build for SQL plugin

raven-worx

[quote author="mbnoimi" date="1379676626"]Guys this thread took a long discussion. Does any one built Qt statically with one of SQL plugins (except sqlite)?[/quote]

When your postgresql plugin isn't built with the same compiler it maybe that i can't load the symbols from the DLL.
Thus to make sure you can try to build it yourself and retry it then.

Also, don't forget the licensing issues with static linking to Qt "explanation here":http://www.slideshare.net/qtbynokia/qt-licensing-explained

I followed up the pointed wiki page by downloading Postgresql from "this link":http://ftp.postgresql.org/pub/source/v9.1.9/postgresql-9.1.9.tar.bz2 then used the following options:

[code]$ ./configure --without-zlib --with-openssl --with-includes=C:/OpenSSL-Win32/include --with-libraries=C:/OpenSSL-Win32/lib
/MinGW [/code]

but I got error during configure process:
[code]checking openssl/ssl.h usability... no
checking openssl/ssl.h presence... no
checking for openssl/ssl.h... no
configure: error: header file <openssl/ssl.h> is required for OpenSSL [/code]

Do you've an idea how to fix this issue?

P.S. "Some guy faced it before":http://web.archiveorange.com/archive/v/V95x82sNS8lCeW2yiGEY but he couldn't find any response :(

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 ?

mbnoimi

[quote author="SGaist" date="1379883992"]Did you clean before trying with the space ?[/quote]

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 !!!

mbnoimi

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
