libQt...4d.a files set

[brokensword]

Hi everyone. I know: 99% of questions about Qt is installation problems of open-source version (I think Trolltech made it specially for increasing sales of commercial version . My question is not trivial, haven't found it yet (except my same one on qtforum.org),

I'm trying to compile Qt 4.3.1.

Here is my script:

@echo off
rem
rem This file is generated
rem
 
echo Setting up a MinGW/Qt only environment...
echo -- QTDIR set to C:\Qt\4.3.1
echo -- PATH set to C:\Qt\4.3.1\bin

cd %QTDIR%

There are no problems with paths etc. All processes passed without any error. I've just one big problem: can't compile programs which use libQt...4d (e.g. - libQtGui4d) libs (v4 debug libs). There are all other versions of libs compiled and placed into lib folder (e.g. - there are libQtGuid.a, libQtGui.a, libQtGui4.a).

Programs which doesn't use v4 debug libs are also compiled and launched successfully.

I've spent two days without any hint. There are no such problem reports yet in internet. I think most of Qt users suspect nothing about absence of v4 debug libs.

So questions are:
1. Does anyone have libQt...d4.a files in Qt lib folder yet? If yes - give me some clue - what I've missed and where. What for these "v4" versions needed yet?

2. Does qtmake launching (commented in my script) is neccessary? What does it do at all in my case?

In officialy generated qtvars.bat it's present, in lot of forum posts - absent. Who knows?

Thanks for any questions.

I don't know if it helps, but for the shared version the debug libraries are in the bin directory.

Here is how I compile the Qt Windows Opensource version.
As it uses mingw, which sets INCLUDE and LIB environment variables, and this causes compilation errors in some machines. So after talking to hte trolltech support team( and ya, they answers question from Opensource guys ). they have asked me to unset these varaibles. So I edited my qtvars.bat ( C:\Qt\4.3.1\bin\qtvars.bat ) file as follows

@echo off
rem
rem This file is generated
rem
 
echo Setting up a MinGW/Qt only environment...
echo -- QTDIR set to C:\Qt\4.3.1
echo -- PATH set to C:\Qt\4.3.1\bin
echo -- Adding C:\MinGW\bin to PATH
echo -- Adding %SystemRoot%\System32 to PATH
echo -- QMAKESPEC set to win32-g++
 
set LIB=
set INCLUDE=
set QTDIR=C:\Qt\4.3.1
set PATH=C:\Qt\4.3.1\bin
set PATH=%PATH%;C:\MinGW\bin
set PATH=%PATH%;%SystemRoot%\System32
set QMAKESPEC=win32-g++
 
if not "%1"=="compile_debug" goto END
cd %QTDIR%
echo This will configure and compile qt in debug.
echo The release libraries will not be recompiled.
pause
configure -plugin-sql-sqlite -plugin-sql-odbc -qt-libpng -qt-libjpeg
cd %QTDIR%\src
qmake
mingw32-make debug
:END

@echo off
rem

set LIB=

set PATH=C:\Qt\4.3.1\bin
set PATH=%PATH%;C:\MinGW\bin
set PATH=%PATH%;%SystemRoot%\System32
set QMAKESPEC=win32-g++

if not "%1"=="compile_debug" goto END
cd %QTDIR%

pause
configure -plugin-sql-sqlite -plugin-sql-odbc -qt-libpng -qt-libjpeg
cd %QTDIR%\src
qmake
mingw32-make debug
:END

Notice the set LIB= and INCLUDE= ( linenumber 13, 14 )
Works for me

Maybe this question sounds stupid, but what is the point of having static debug libraries (unless you just want to fill up your harddisk and you didn't find an easier way to do it)?

[brokensword]

Thanks for your answers. Solution was found. libQt...d4.a files are creating for "shared" compilation ONLY. They are absent after "static" compilation of Qt sources.
Many makefiles of "examples" and "demos" after "static" compilation contains "...d4" libs references. I think it's a some sort of bug. qmake shouldn't put refs to "...d4" libs while Qt configured statically. Btw - after patching Makefiles manually and removing "4" at the end of lib names - they are compiling perfectly.

So - is that a bug of qmake?

[wysota]

It's not a bug (at least not directly). When compiling statically, you should only compile sub-src (thus omitting examples, tools, etc.) and it would have worked anyway if you told qmake to compile in release mode.

I'd still like to know the answer to my question

[brokensword]

If you mean "what is the point of having static debug libraries" - my point is that compiled statically apps loads faster. It takes much more time to load all dinamically linked libraries then statically linked ones.

[wysota]

But in such situation (if the load speed was your primary goal) you'd use libraries built in release mode and not in debug mode. Use of these only makes sense when you're developping the application and that's usualy done with shared libraries (among other reasons the compilation is faster).

[brokensword]

Thanks. Problem solved. Just put somewhere in faq that ...d4 libs in static mode aren't created.

[brokensword]

btw, "sub-src" param doesn't helps - all examples and demos are compiled (including ..d4 libs which aren't existing). I still think it's at least low-level priority bug.

[wysota]

btw, "sub-src" param doesn't helps - all examples and demos are compiled

This is not possible. You must have used it in a wrong way (your script in the first post is invalid - it changes the current directory to src and then calls make sub-src, instead of calling it from the top level directory). I meant something like this:

cd qtsourcedir
configure.exe -static
make sub-src

[brokensword]

it builds examples and demos anyway.

QT_BUILD_PARTS -= examples
QT_BUILD_PARTS -= demos

solve this problem.

[brokensword]

btw, the main question remains - why static "*d4.a" libraries can't be built?

[wysota]

I don't know if they *can't* be built, but if so, then I'd say that because nobody assumed that anyone would ever want to build them.
