PostgreSQL plugin building in Windows 7

SGaist

It can't find the libpq-fe.h header file, are you sure you added the include path where that file can be found ?

TerraxQt

The file is in C:\PostgreSQL\9.3\include:

Change the \ to / for the paths you give to qmake. Also on windows Qt uses unix style path, so you are giving it invalid paths.

TerraxQt

same result :)

Check the content of the Makefile to see if there's a line containing the path to PostgreSQL includes

TerraxQt

The Makefile which is in C:/Qt/5.1.1/Src/qtbase/src/plugins/sqldrivers/psql has the line:

Command: C:\Qt\5.1.1\mingw48_32\bin\qmake.exe INCLUDE+=“C:/PostgreSQL/9.3/include” LIBS+=“C:/PostgreSQL/9.3/lib/libpq.lib” -o Makefile psql.pro

The Makefile which is in C:\Qt\5.1.1\mingw48_32\bin has the line:

Command: C:\Qt\5.1.1\mingw48_32\bin\qmake.exe "INCLUDEPATH+=C:\Program Files\PostgreSQL\9.3\include" "LIBS+=C:\Program Files\PostgreSQL\9.3\lib\libpq.lib" -o Makefile C:\Qt\5.1.1\Src\qtbase\src\plugins\sqldrivers\psql\psql.pro

SGaist

Why do you have a Makefile in the C:\Qt\5.1.1\mingw48_32\bin folder ?

You should clean everything and then try to build the plugin again

TerraxQt

I don't know why there is a Makefile :) By clean everything you mean re-install Qt and PostgreSQL ?

SGaist

No, PostgreSQL seems to be installed fine, just clean the sources and check whether you have something unusual in the mingw related folders

TerraxQt

Here is what I did:
-Re-installed Qt
-Opened the Console from Qt's folder in start menu
-Executed:

C:\Qt\5.1.1\Src\qtbase\src\plugins\sqldrivers\psql>qmake INCLUDEPATH+="C:/PostgreSQL/9.3/include" LIBS+="C:/PostgreSQL/9.3/lib/libpq.lib

After that:
C:\Qt\5.1.1\Src\qtbase\src\plugins\sqldrivers\psql>mingw32-make

And the result:

Is it possible that for Qt ver. 5.1.1 the building of the plugin is done in different way?

SGaist

Just stumbled upon "this":http://qt-project.org/forums/viewthread/24460
Worth a try
