Yeah, closer and closer...

So, I did:
Qt Code: 
  1. C:\Qt\4.3.3\src\plugins\sqldrivers\psql>qmake -config release -o Makefile "INCLU
  2. DEPATH+=C:\psql\include" "LIBS+=C:\psql\lib\liblibpq.a" psql.pro

And:
Qt Code: 
  1. C:\Qt\4.3.3\src\plugins\sqldrivers\psql>make
To copy to clipboard, switch view to plain text mode 

In beginning it was all right, but after that...
