QPSQL driver in windows

[brevleq]

I tried compile the QPSQL driver but it returns a lot of errors:

vos de programas\PostgreSQL\8.2\include" "LIBS+=C:\Arquivos de programas\Postgre

I didn't understand!! I did all qt help instructions!

[jpn]

Notice the difference:

C:\Qt\4.3.2\src\plugins\sqldrivers\psql>qmake -o Makefile "INCLUDEPATH+=C:\Arqui
vos de programas\PostgreSQL\8.2\include" "LIBS+=C:\Arquivos de programas\Postgre

-I"..\..\..\..\mkspecs\win32-g++" -o tmp\obj\release_shared\qsql_psql.o ..\..\..
\sql\drivers\psql\qsql_psql.cpp

So try:

qmake -o Makefile "INCLUDEPATH+=\"C:\Arquivos de programas\PostgreSQL\8.2\include\"" "LIBS+=\"C:\Arquivos de programas\PostgreSQL\8.2\lib\ms\libpq.lib\"" psql.pro

[brevleq]

With this qmake I can't start neither the compilation:


C:\Qt\4.3.2\src\plugins\sqldrivers\psql>qmake -o Makefile "INCLUDEPATH+=\"C:\Arq
uivos de programas\PostgreSQL\8.2\include\"" "LIBS+=\"C:\Arquivos de programas\P
ostgreSQL\8.2\lib\ms\libpq.lib\"" psql.pro

C:\Qt\4.3.2\src\plugins\sqldrivers\psql>make

Search the forums for "multiple target patterns", please.

[brevleq]

I searched in google but I didn't found anything that could help me!!

Don't you have the compiled driver??

If you have, could you send me??

I searched in google but I didn't found anything that could help me!!

I meant searching Qt Centre forums. Look, there's a "Search" item in the link bar on top of every page. There have been a bunch of similar "multiple target patterns" problems lately and I'm quite sure this is the same problem.

Don't you have the compiled driver??

If you have, could you send me??

I'm sorry I'm afraid I don't.

[brevleq]

Hey JPN!!
I tryied something that maybe could solve the problem!!
I reinstalled postgre in C:\psql consequently the qmake command is:

C:\Qt\4.3.2\src\plugins\sqldrivers\psql>qmake -o Makefile "INCLUDEPATH+=C:\psql\
include" "LIBS+=C:\psql\lib\ms\libpq.lib" psql.pro

How you can see no erros ocurred... but my program still say to me:

Driver not found

where should the driver be and what is his name?

[jpn]

Shouldn't you reconfigure and build Qt with psql support? Similarly than is done with MySQL in here: Building the QMYSQL plugin on Windows using MinGW

cd C:\Qt\4.3.2
configure -plugin-sql-psql
make

[brevleq]

huahua

another problem. When I tried to recompill my program:

C:\caixa_xpress>qmake *.pro

C:\caixa_xpress>make
mingw32-make -f Makefile.Debug
mingw32-make[1]: Entering directory `C:/caixa_xpress'

mingw32-make[1]: *** [debug\caixa_xpress.exe] Error 1
mingw32-make[1]: Leaving directory `C:/caixa_xpress'
mingw32-make: *** [debug] Error 2

What it didn't found?

I did this before:

cd C:\Qt\4.3.2
configure -plugin-sql-psql
make
[/HTML]

You're attempting to compile a debug version of the application while you have no debug version of Qt itself built. Either build a release version of the application:

make clean
qmake -config release
make

or build a debug version of Qt (there is a shortcut in the start-menu in case you installed Qt from a binary installer, otherwise see "configure -help").

now it compilled but still saying:

driver not Loaded

I can't understand!! It works so well in Slackware 12!!
