PostgreSQL plugin building in Windows 7
-
Hi SGaist,
Thanks for this.
This is what I get after inputting this command:
C:\Qt\5.1.1\mingw48_32>qmake "INCLUDEPATH+=C:\Program%Files\PostgreSQL\9.3\include" "LIBS+=C:\Program%Files\PostgreSQL\9.3\lib\libpq.lib" C:\Qt\5.1.1\Src\qtbase\src\plugins\sqldrivers\psql
Project ERROR: Project has no top-level .qmake.conf file. -
First things, you should move/reinstall PostgreSQL in a folder without space, it will save you a lot of troubles.
And you should call qmake directly in the plugin folder

Hello Sgaist,
Today I uninstalled PostgreSQL which was 64-bit and installed the 32-bit version. After that I opened the console from Start menu->All Programs->Qt 5.1.1->5.1.1->MinGW 4.8 (32-bit)->Qt 5.1.1 for Desktop.
After that I went in C:\Qt\Qt5.1.1\5.1.1\Src\qtbase\src\plugins\sqldrivers\psql
and executed the command:C:\Qt\Qt5.1.1\5.1.1\Src\qtbase\src\plugins\sqldrivers\psql>qmake INCLUDE+="C:\PostgreSQL\9.3\include" LIBS+="C:\PostgreSQL\9.3\lib\libpq.lib"
After that I executed mingw32-make and it started to print output (which is something new) but ended with error. Below is the whole output with the errors at the end:
C:\Qt\Qt5.1.1\5.1.1\Src\qtbase\src\plugins\sqldrivers\psql>mingw32-make

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

Check the content of the Makefile to see if there's a line containing the path to PostgreSQL includes
-
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
-
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
-
No, PostgreSQL seems to be installed fine, just clean the sources and check whether you have something unusual in the mingw related folders
-
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-makeAnd the result:

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