compilation error

[lyuts]

Try adding QT += gui to you .pro file.

[jjbabu]

I tried by adding "QT += gui" to my .pro file and also i included "#include <QtGui>" in my .cpp file,but the result is same.

i have visual studio 2005 in my system,but i have not integrated my qt with visual studio.
is VS2005 cause for this errors?

previously i installed qt with minGW on my windows system with out having VS2005.at that time examples of qt are compiled fine,but know i am facing this problem.

what is the reason behind this anyone can explain?
thanks...

did you build Qt for VS2005?

Try adding QT += gui to you .pro file.

this flag included by default, from docs

By default, QT contains both core and gui, ensuring that standard GUI applications can be built without further configuration.

Yeah, that's right until a user modifies qmake.conf. Someone might prefer to change the default settings.

[jjbabu]

of course by default that will be added to our project,but what are the reasons behind those errors.i tried so many ways,but i couldn't rectify those errors.not even examples in the qt are running.

[spirit]

ask you again: did you build Qt for VS2005?
do you use only minGW or VS2005 too?

[jjbabu]

i have not build qt with VS2005.i am directly using qt.

[spirit]

so, why did you ask about VS? I thought that you have Qt built for MinGW and you try to use this Qt version with VS.
did you try to make mingw32-make clean & qmake & mingw32-make?

[jjbabu]

Spirit let me explain clearly what is my problem:

STEP1:there is no qt on my machine,it is having VS2005 and .NET framework.

STEP2:Now i want to develope QT applications,For that reason i downloaded QT version "qt-win-opensource-4.4.3-mingw" and installed along with MINGW in my "C" directory.

STEP3:i created folder in "C:\Qt\4.4.3" with the name hello and i placed "hello.cpp" file

STEP4:using "QT4.4.3 command prompt" i compiled my application,for compilation i used
qmake -project ; qmake ;make.

at this point of time i got errors of unreferensed which are montion in my 1st post.

where i did wrong? please help me...

[spirit]

looks like you did right steps.
can you show us what returns this command echo %QTDIR% in "QT4.4.3 command prompt".

[jjbabu]

it is showing like below:

C:\Qt\4.4.3

[jjbabu]

are u interested to see any of my system variables and user variables?

[spirit]

I don't know what to say you, looks like you did everything right.
I don't know what to suggest you except as remove this Qt installation at all, reinstall it and try to compile an example again.

[jjbabu]

i did 3times(QT uninstall and installation) as u mentioned in your last post,but no use..i am using qt from last 3 yrs,but i never faced this type of problem.

[talk2amulya]

i think after VS2005 was installed by you, some internal variables changed, i m not sure though..could you please post the make file that qmake generates..

Yes, everything except maybe trying to compile the example from the Qt command prompt. Seems it is missing the include and lib dirs.
