problems compiling tutorial 7...
Message 1 in thread
First, I like to thank all the people that helped me with tutorial #1, now I'm
on #7 !!!
How I compile tutorial #7??? I tried with
cc -I/usr/include/qt -o tut7 main.cc -lqt
but I get this error:
/tmp/ccXKfxtr.o: In function `MyWidget::MyWidget(QWidget *, char const *)':
/tmp/ccXKfxtr.o(.text+0x1b5): undefined reference to `LCDRange::LCDRange(QWidget *, char const *)'
collect2: ld returned 1 exit status
I think it is because like now I'm using more than one .cpp file, I got to
compile it in another way, I'm right??? or what I have to do???

You think right, you should add all C++ sources to cc this way (there are other ways of compilations)
You should by the book Linux Application Development (Johnson and Troan): chapter 4 and 5 is for you.
cc -I/usr/include/qt -o tut7 main.cc lcdrange.cc xxx.cc yyy.cc -lqt
