how to type this long command to compile a kde program?
 
trying to learn some basics of KDE programming.
according to the book, the command to compile a simple program is:
g++ khello.cpp -I$KDEDIR/include
I/usr/include/qt -L$KDEDIR/lib -lkdeui -lkdecore -ldl -lqt

i cannot understand how to type this command in fact.
what does the "." in the second line do?

I saved the command and did a cat -t -e -v to see how it looks and got:
g++ khello.cpp -I$KDEDIR/include$
M-BM-7 I/usr/include/qt -L$KDEDIR/lib -lkdeui -lkdecore -ldl -lqt$

so the "." is actually "M-BM-7". How to actually type this command?
Thanks very much.

I think this is how that command line should look

Code:

g++ khello.cpp -I$KDEDIR/include -I/usr/include/qt -L$KDEDIR/lib -lkdeui -lkdecore -ldl -lqt
The dot should be a - it may simply be a mistake.

but cannot compile because several headers are missing:
qstring.h: No such file or directory
kapp.h: No such file or directory
klined.h: No such file or directory

those header files are in the location defined by $KDELIB and $QTLIB.
i also tried to use the complete path name but did not work either :-(
so i am wondering if that dot really means something.

Do you have $KDEDIRS set properly? The files that you are getting errors for should be in /usr/include/qt and $KDEDIRS/include

-I is for the include path.

I believe this is the time when you learn about Makefiles ;)

sorry, i just find that klined.h is not available.
which package shall i install?
is it kdelibs-devel? tons of packages i have to install in order to
install this guy. and confliction exists which makes me no idea.
e.g., i am required to install alsa-lib, libasound etc. which i think
may not be relevant to my problem at all.

thanks.

Yes you'll definitely need kdelibs-devel and probably qtlibs-devel as well.
