QMAKESPEC has not been set, so configuration cannot be deduced

[Rekha]

hi to everyone,
i'm new to this forum.. i installed qt-x11-opensource-src-4.1.4 version n wrote a simple program to vieww the dialog box that was created using qtdesigner from command mode.
the commands that were used are,uic -o sample.h sample.ui .... to generate a sample.h file
qmake -project sample.pro ......... to create a .pro file
qmake -o makefile qt.pro ............. to build the file
but when i gave that command i got the following errors,
................................
MAKESPEC has not been set, so configuration cannot be deduced.
Error processing project file: qt.pro
..................

so please suggest me now what should i do?:confused:

qmake -project sample.pro
qmake -o makefile qt.pro
Shouldn't it be "qmake -o makefile sample.pro"?

[Rekha]

By default the .pro file generated by this command,
qmake -project sample.pro
is
qt.pro..
so i need to use that qt.pro than sample.pro
PLZ help me in solving this problem

And what keeps you from setting QMAKESPEC? Or from using "qmake -spec linux-g++" or whatever your spec is?

[jacek]

By default the .pro file generated by this command,
qmake -project sample.pro
is
qt.pro..
so i need to use that qt.pro than sample.pro
No, you don't --- you just forgot to add "-o" before sample.pro:
qmake -project -o sample.pro

I know is an old issue, but still unanswered...

Maybe the error is because you didn't load the QMAKESPEC env variable. You can look the ones you can choose on /usr/share/qt4/qmakespec (or qt3, depending)

set env QMAKESPEC linux-g++ (or instead linux-g++, yours)

In the compilation directory:

qmake -project
qmake
make

Hi, I've just got a similar question..
Is it normal not to have the folder '/usr/..../mkspecs' when compiling Qt4 from source ? Because I didn't get it after 'make install' ?
I managed to copy it from somewhere else .. but is this normal ?

Did you pass any paths to configure?

[yehdev_cc]

Did you pass any paths to configure?
No I didn't ... :confused:

[jacek]

No I didn't ...
Then Qt should install itself in /usr/local/Trolltech/Qt-<version>. What does "qmake -query QMAKE_MKSPECS" print?

[yehdev_cc]

I just copied this directory from elsewhere... so, the output now may not give a very useful information about the problem .. I think.
I just don't know why this happened.. it should have created the folder, as make completed successfully without errors...

Just add this to the script before you run qmake.
Unix Bourne shell:

QMAKESPEC=/usr/local/qt/mkspecs/linux-g++
PATH=$PATH:/local/qmake/bin
export QMAKESPEC PATH

Unix C shell:

setenv QMAKESPEC /usr/local/qt/mkspecs/linux-g++
setenv PATH $PATH:/local/qmake/bin

Microsoft Windows:

set QMAKESPEC=c:\qt\mkspecs\win32-msvc
set PATH=%PATH%;c:\qmake\bin

qmake is now installed.
