Hi,

I am a newbie and have a preinstalled QT designer. It comes with the library at /usr/lib/qt3/include.

Every time i do 'make' after 'qmake' it says :

g++ -c -pipe -Wall -W -O2 -fomit-frame-pointer -pipe -march=i586 -mcpu=pentiumpro -DQT_NO_DEBUG -I/usr/lib/qt3//mkspecs/default -I. -I. -I/include -o main.o main.cpp

from main.cpp:7:

/usr/lib/qt3/include/qglobal.h:773:23: qfeatures.h: No such file or directory
make: *** [main.o] Error 1

What's wrong, the library is there on the place, this give me a lot of headache. Please anyone bring me the magic cure.

Thanks

Try searching for qglobal.h. E.g., try locate qglobal.h and post the result here.

I ran :
# locate qglocal.h
the result :
/usr/lib/qt3/qglobal.h

is there ...

Did the error has something to do with the QTDIR variable
Could it be that the QTDIR has not been configured properly or misconfigured ?

I ran :
# locate qglocal.h
the result :
# /usr/lib/qt3/include/qglobal.h

is there (i think)...

Did the error has something to do with the QTDIR variable.

Maybe... your QTDIR environment variable should be set to /usr/lib/qt3 in your case... actually, looking at this bit from your compile line

..sr/lib/qt3//mkspecs/de..

it seems very probable. Try echo $QTDIR and see what it is set to.

I ran :
# echo $QTDIR
result :
blank ....

Any suggestion ?

Try setting it to "/usr/lib/qt3"....

I put QTDIR=/usr/lib/qt3
in my /etc/profile and I re-login

I re-run
#/usr/lib/qt3/bin/qmake -o Makefile mypro.pro
#make

Now I get syntax error too (I actually folowing the QT tutorial

You also have to set your QPATH to
QPATH=/usr/lib/qt3/bin
in your /etc/profile or in /home/"your userid"/.bashrc

I've followed your advice, it didn't solve the problem.
Why do we have to set the QPATH to /usr/lib/qt3/bin ?

well at least you got as far as the make portion, i get a message saying qmake: command not found eveytime i try to build my program. Any ideas why it doesnt recognize the qmake command?

I work this way:
1.) Create my Qt program (*.ui and .ui.h and main.cpp)
2.) Run qmake -project (in the same direcory where the programfiles are located)
this vill create a *.pro
3.) Run qmake (that will create the Makefile
4.) make

point 2-3 is run only once
( * = the names of your files.)

qmake needs the $QPATH

I hope this will help you

actually it does

Wow, my program is now working
Ok i'll take the next headache

Thank you very much
