Problem compiling PostgreSQL driver with Qt-SDK 2010.02.01

[NoRulez]

Hey @all,

did anybody know the reason why the PostgreSQL driver can't be compiled with the "new" SDK?
When I try to compile the driver i still get the error

c:/qt/2010.02.1/mingw/bin/../lib/gcc/mingw32/4.4.0/../../../../mingw32/bin/ld.exe:psql.pro: file format not recognized; treating as linker script
c:/qt/2010.02.1/mingw/bin/../lib/gcc/mingw32/4.4.0/../../../../mingw32/bin/ld.exe:psql.pro:1: syntax error

To copy to clipboard, switch view to plain text mode 

The psql.pro file isn't changed at all, but here it is:

TARGET	 = qsqlpsql
 
HEADERS		= ../../../sql/drivers/psql/qsql_psql.h
SOURCES		= main.cpp \
		  ../../../sql/drivers/psql/qsql_psql.cpp
 
unix: {
    !isEmpty(QT_LFLAGS_PSQL) {
        LIBS *= $$QT_LFLAGS_PSQL
        QMAKE_CXXFLAGS *= $$QT_CFLAGS_PSQL
    }
    !contains(LIBS, .*pq.*):LIBS *= -lpq
}
 
win32:!contains(LIBS, .*pq.* ) {
    !win32-g++:LIBS    *= -llibpq       
    win32-g++:LIBS *= -lpq	
    LIBS    *= -lws2_32 -ladvapi32
}
 
include(../qsqldriverbase.pri)

I hope someone could help

It looks like ld.exe wants to parse psql.pro. How you compile this Postgres plugin?

[NoRulez]

I've made it as described in the Qt documentation How to Build the QPSQL Plugin on Windows, but with mingw32-make instead.

[faldzip]

can you paste exact command you use?

[NoRulez]

cd %QTDIR%\src\plugins\sqldrivers\psql
qmake "INCLUDEPATH+=C:\Databases\PostgreSQL\8.4\include" "LIBS+=C:\Databases\PostgreSQL\8.4\lib\libpq.lib" psql.pro
mingw32-make

cd %QTDIR%\src\plugins\sqldrivers\psql
qmake "INCLUDEPATH+=C:\Databases\PostgreSQL\8.4\include" "LIBS+=C:\Databases\PostgreSQL\8.4\lib\libpq.lib" psql.pro
mingw32-make

To copy to clipboard, switch view to plain text mode 

I also tried the following after reimp, but the same error message occurs

qmake "INCLUDEPATH+=C:\Databases\PostgreSQL\8.4\include" "LIBS+=C:\Databases\PostgreSQL\8.4\lib\libpq.a" psql.pro

qmake "INCLUDEPATH+=C:\Databases\PostgreSQL\8.4\include" "LIBS+=C:\Databases\PostgreSQL\8.4\lib\libpq.a" psql.pro

To copy to clipboard, switch view to plain text mode 

Best Regards
NoRulez

[faldzip]

and what if you try this:

qmake "INCLUDEPATH+=C:\Databases\PostgreSQL\8.4\include" "LIBS+=-LC:\Databases\PostgreSQL\8.4\lib -lpq" psql.pro

qmake "INCLUDEPATH+=C:\Databases\PostgreSQL\8.4\include" "LIBS+=-LC:\Databases\PostgreSQL\8.4\lib -lpq" psql.pro

To copy to clipboard, switch view to plain text mode

OK, thank you

i will try it today in the evening and will give you feedback.

okay, do you have an libpq.a in your C:\Databases\PostgreSQL\8.4\lib?

[NoRulez]

I've got the same problem.
So dificult to solve this. I spend several hours trying to build this driver.
Why is so complicated?
Why somebody that has put on the internet available to download?

Hi All,
This issue is hanging around as a big problem for anyone using PostgreSQL with QT on windows, I have a post here but have had no response : http://www.qtcentre.org/threads/2988...222#post142222
I have spent 4 days getting the plugin built only to have continuing trouble getting the runtime environment to load it. For the moment someting else has come up so I haven't been able to finish this but when I left it I still couldn't use PostgreSQL with QT on a Windows 7 64-bit platform. The documentation is non-existent in any helpful way, however with enough google searches I eventually got a solution to building the driver. Although I tried so many options I can hardly remember the set of steps that finally worked and that only got the plugin built, I still can't get it to load. What would be really helpful is a more detailed step-by-step guide on how to build and intergrate this plugin on windows rather than the 3 line solution that is currently available. Or even better would be a pre-built windows download of the plugin and guide on how to integrate it in your code. While its easy to propsoe this idea I do understand that its probably not simple, however it would probably require an experienced user to get this done right, which unfortunately I'm not. However, if I can help test a solution I'm more than willing.

I've also Windows 7 64 bit, so i think the problem is to integrate the plugin with the Windows 7 and/or the 64 bit environment.
