[spirit]

this is wrong

LIBS+=c:\Program Files\PostgreSQL\8.3\lib\libpq.dll

I mean libpq.dll must be libpq.a for creation this lib you need apply dlltool (which is located in bin dir of mingw) for libpq.dll.

[dummystories]

Thanks for finding error. I found dlltool at bin directory of MinGW.

now what should i do.

Regards

Narasimha Raju. Naidu

[spirit]

this should help you
edit: link updated.

[dummystories]

Hi,

Thanks for your replies and references. I did according to the instruction in the link. it successfully generated libpq.a file.

What should i do now.....

Waiting for your reply


Regards,

Narasimha Raju. Naidu

[spirit]

do this

qmake "INCLUDEPATH+=%POSTGRESQLDIR%\include" "LIBS+=%POSTGRESQLDIR%\lib\libpq.a" psql.pro
mingw32-make

that's all.
PS. I forgot, for successfully launching application with PSQL driver you need to add PostgreSQL's bin directory to your PATH variable.

thanks for your reply. i did according to your instructions but i got the following result

are you sure that this path "C:\Program Files\PostgreSQL\8.3\include" is corrent? is libpq-fe.h located in "C:\Program Files\PostgreSQL\8.3\include"?

yes all are correct but still i am getting same errors

Problem is with spaces in Yours PostgreSQL dir name (c:\Program Files\PostgreSQL\8.3). Try this :

qmake INCLUDEPATH+="C:\Program Files\Pos
tgreSQL\8.3\include" LIBS+="c:\Program Files\PostgreSQL\8.3\lib\libpq.a" psql.pr
o

qmake INCLUDEPATH+="C:\Program Files\Pos
tgreSQL\8.3\include" LIBS+="c:\Program Files\PostgreSQL\8.3\lib\libpq.a" psql.pr
o

To copy to clipboard, switch view to plain text mode 

Look at differently located char " in INCLUDEPATH and LIBS.

C:\MinGW\bin>dlltool --dllname libpq.dll --def libpq.def --output-lib libpq.a
dlltool: Can't open def file: libpq.def
