[SOLVED]can't find the "src" directory to build my QPSQL driver

k_arnaud

Hi Clochydd, i've downloaded Qt with mingw32...
About the #11 here is the error message i get: "cannot find file psql.pro"

clochydd

Hi k_arnaud, the message says that the project file for building the plugin cannot be found.
Did you go to the plugins directory:
8. cd QT_SRC_PATH\src\plugins\sqldrivers\psql
If so, does the psql.pro exist here?

k_arnaud

after entering mingw32-make debug , in the unreadable message i get, i can see makefile:48: recipe for target 'debug' failed and i get the same with release

clochydd

You should check your pathnames again - it seems that dependencies cannot be found. If you cannot find a fault: What is the unreadable message?

k_arnaud

may be the problem is from here QTSDK_SQLDRIVERS_PATH=C:\Qt\Qt5.2.0\5.2.1\mingw48_32\plugins\sqldrivers i don't know wehter i should replace "QTSDK_SQLDRIVERS_PATH" with anything

clochydd

Hi k_arnaud, with "set QTSDK_SQLDRIVERS_PATH=C:\Qt\Qt5.2.0\5.2.1\mingw48_32\plugins\sqldrivers" you create the environment-variable QTSDK_SQLDRIVERS_PATH, which you need later (#12.). Where appropriate you must modify the path itself - according to your system.
These variables are for your comfort - you may use the complete pathname instead.

k_arnaud

that is what i did, i entered QTSDK_SQLDRIVERS_PATH=C:\Qt\Qt5.2.0\5.2.1\mingw48_32\plugins\sqldrivers in the CMD-windows without any change

clochydd

maybe a silly question: did you enter "set QTSDK..." and is that visible in your environment if you type SET in the cmd?

k_arnaud

No, i ca'nt see that

clochydd

But - do you use SET to bring it to the environment?

k_arnaud

i tried again, and i can see the three variables; QTSDK_SQLDRIVERS_PATH, QT_SRC_PATH and
POSTGRES32

clochydd

are you able to build the plugin now? You should not see the "recipe" message again.

k_arnaud

sorry i can't. "qmake is not a command line", that is the error message when i try to buld with CMD-window. But when i try with the the "qt-cmd" i get the same error message "recipe..."

clochydd

must be a wrong path, too:
your_qt_path is something like C:\Qt\Qt5.2.1\5.2.1 and
qmake.exe is located in your_qt_path\mingw48_32\bin
so you must start qmake by:
your_qt_path\mingw48_32\bin\qmake “INCLUDEPATH+=%POSTGRES32%\include” “LIBS+=%POSTGRES32%\lib\libpq.lib” psql.pro

when this task is done, you will continue with:
mingw32-make debug
mingw32-make release

k_arnaud

here is the error message when i did what you said : cannot find file psql.pro.
that file is not in the qmake.exe directory so when i enter cd C:\Qt\Qt5.2.1\5.2.1\mingw48_32\bin\qmake “INCLUDEPATH+=%POSTGRES32%\include” “LIBS+=%POSTGRES32%\lib\libpq.lib” psql.pro, i get an error message

clochydd

the psql.pro is in the sources, in the plugin\sqldrivers directory (see above cd QT_SRC_PATH\src\plugins\sqldrivers\psql)
you should start your qmake from THIS directory, not from the ...bin dir!

k_arnaud

When i try to start qmake there, i get an error message "qmake is not a command line..."

clochydd

Do you call qmake with the complete path:
C:\Qt\Qt5.2.1\5.2.1\mingw48_32\bin\qmake
remember to use the path for your machine - maybe you have to modify slightly

k_arnaud

always the same error "recipe for target 'debug' failed"

clochydd

You must be sure, that all pathnames are correct and the commands are called from the right directories.
