Error while building project Byteconverter
When executing build step 'Make'


can someone please look into it and help me with it?
Thanks

This is your .pro file

Code:

---

SOURCES += main.cpp \
    E:/data/Ebukz/Qt/art \
    of \
    building \
    Qt \
    apps/examples/chapter02/byteConverter/ByteConverterDialog.cpp \
    E:/data/Ebukz/Qt/art \
    of \
    building \
    Qt \
    apps/examples/chapter02/byteConverter/ByteConverterDialog.cpp \
    BCD.cpp
HEADERS += BCD.h

---

It contains a lot of errors.
Add at least this line:
TEMPLATE = app

And remove those strange lines pointing to code you're not using.

i never used this command in .PRO file.could you please explain it in details..and even after adding that it does not work..which strange lines do you mean;acc. to me all lines are needed.
Thanks

Sure:

Let me NOT do that and try for yourself first. I'm not your personal slave.
I will help you and give you better responses if you show you tried something yourself.
In other words, show your pro file after you've changed it and I'll tell you where you're wrong.

Dats kewl...thanks

Well,
I did read the qmake manual.Got some details on adding HEADERS,SOURCES etc.But did not find anything particular relating to my application.And could you please tell,in my earlier small examples i didn't use
TEMPLATE=app ;then how did they work?
Thanks

Please have a close look at the contents of SOURCES variable in the project file. Do you really have a file called "of" on your disk?

Default template is "app" so you don't have to insert it explicitely in your project.

Thanks;actually i was just trying an example from a book... just copy pasted it..and that of file came by.

I don't think you did that correctly. I doubt the book contained each word of a filesystem path in a separate line ending with a backslash.

Hey,the program still doesnt work efficiently.Am i using textChanged() as the right signal?
Thanks
