Sqldrivers: Postgresql not found while it is installed and configured (win 8.1, Psql 9.6.6, Qt 5.10.0, MSVC2015_x64)

[dawidp]

My setup:

• Windows 8.1 Pro 64bit
• Qt 5.10.0 (in C:\Qt)
• QMake version 3.1 (Using Qt version 5.10.0 in C:/Qt/5.10.0 /msvc2015_64/lib)
• PostgreSQL 9.6.6 64bit (in C:\Postgresql\9.6)
• Microsoft Visual Studio Community 2015 (Version 14.0.25431.01 Update 3)

I'm trying to build Postgresql driver fot QT but is not found. First i went to http://doc.qt.io/qt-5/sql-driver.html and executed:

C:\Qt\5.10.0\Src\qtbase\src\plugins\sqldrivers\psql>qmake "INCLUDEPATH+=C:/Postgresql/9.6/include" "LIBS+=C:/Postgresql/9.6/lib/libpq.lib" psql.pro

but got error

Cannot read C:/Qt/5.10.0/Src/qtbase/src/plugins/sqldrivers/qtsqldrivers-config.pri: File not found.
Project ERROR: Library 'psql' is not defined.

that file C:/Qt/5.10.0/Src/qtbase/src/plugins/sqldrivers/qtsqldrivers-config.pri doesn't exists so I've searched the internet and found that I need to run qmake sqldrivers.pro so

C:\Qt\5.10.0\Src\qtbase\src\plugins\sqldrivers>qmake sqldrivers.pro

Qt is now configured for building. Just run 'nmake'.
Once everything is built, Qt is installed.
You should NOT run 'nmake install'.
Note that this build cannot be deployed to other machines or devices.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

WTH? I have postgresql installed and I have pg_config in path

Now my questions is: Why Postgresql isn't detected ?

Hi and welcome to devnet,

Is your PostgreSQL installation built with the same version as Qt ?

You should also add the "INCLUDEPATH+=C:/Postgresql/9.6/include" "LIBS+=C:/Postgresql/9.6/lib/libpq.lib" parameters to your qmake call in the sqldrivers folder.

I've installed binary version of Postgresql 9.6.6 from enterprisedb.com (redirected from postgresql.org for Windows binary distributions) so I don't know with which compiler was used to build it. And Qt installer was download from Qt website. I did not compile Qt ot Postgresql.

I'll try to compile Postgresql from souces....

Before building something, you can use Dependency Walker for example to check the architecture. That also must match.

The Qt installer can install any officially provided Qt version, so you should know what Qt version you actually installed.
