Qt Postgresql driver build failed

Question

I downloaded zip archive of the binaries from Postgresql website, unpacked it. Then found .pro file in "...\src\plugins\sqldrivers\psql". When I tried to built postgresql driver (qmake and then nmake ofc) I get this error messages:

LINK : fatal error LNK1104: cannot open file ''C:/CL/pgsql/lib.obj''
NMAKE : fatal error U1077: "C:\Program Files (x86)\Microsoft Visual Studio 9.0\V
C\BIN\link.EXE": return code "0x450"
Stop.
NMAKE : fatal error U1077: "C:\Program Files (x86)\Microsoft Visual Studio 9.0\V
C\BIN\nmake.exe": return code "0x2"

What is lib.obj here? There definently no such files in postgres zip archive (I followed instruction and there said that files in posgresql /lib and /include enough ) where could it be? Or, maybe, I missed something?

Here's my psql.pro file

TARGET = qsqlpsql

SOURCES = main.cpp
INCLUDEPATH += "C:/CL/pgsql/include"
LIBS+="C:/CL/pgsql/lib"
include(../../../sql/drivers/psql/qsql_psql.pri)

include(../qsqldriverbase.pri)

Answer 1

You might want C:/CL/pgsql/lib/libpq.lib instead, referring to the specific file of interest.

I haven't used QMake in ages, but that's how it looks from the error.

(See RobbieE's answer for the docs link and explanation).

Answer 2

LIBS refers to both directories and single files depending on the switches

See the documentation for a description on how to use it.
