Static build for SQL plugin

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 :)

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?

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]

Sorry, I made a typo for the import macro... I've corrected the post

[quote author="SGaist" date="1380405617"]Sorry, I made a typo for the import macro... I've corrected the post[/quote]

Thanks for correction. Now Qt gave me a new error message about missing qsqlpsql as following:
[code]c:/mingw48_32/bin/../lib/gcc/i686-w64-mingw32/4.8.0/../../../../i686-w64-mingw32/bin/ld.exe: cannot find -lqsqlpsql
collect2.exe: error: ld returned 1 exit status

Error while building/deploying project test (kit: Static PG)

17:07:16: Elapsed time: 00:13.[/code]

For fixing this issue I tried to find the missing library but unfortunately I couldn't find it!

NOTE: Qt built successfully and it didn't show any error message (by using "the above options":https://qt-project.org/forums/viewreply/144398/)

You won't have any plugin lib since they are built in Qt's sql library, did you add qsqlpsql in your pro file ?

Just thought that since you have all sql plugins built in you might not need the QTPLUGIN line from the pro file

Unfortunately it didn't fix the issue and generated ton of errors as shown in full log of build process: http://paste.kde.org/p96ac01e7

I'm really frustrated; The hardest step done (building Postgresql with MinGW) while the supposed easy one delays the success!!!

SGaist

Looks like it needs postgresql symbol, you have to add the link information to postgresql

How can I do it?

SGaist

Add the same -l and -L to LIBS that you used to build Qt with postgresql

I already added them as mentioned in "a reply before":https://qt-project.org/forums/viewreply/144622/.
