Qt4 make error ?
Message 1 in thread
This error doesn't make sense, I've done a search and found 3 references
which are all in this newsgroup, but none of them had a solution.
It's an example from the book "C++ GUI Programming with Qt 4".
I typed in the code, and as it didn't compile, I tried copying the text from
the CD, but the error is the same. I compile the program with the following
Commands:
qmake -project
qmake
make
This is the output on the console:
/usr/bin/qmake -unix -o Makefile QTProjects.pro

What's in line 9 of sortdialog.h?
If you could make the whole project available, including sortdialog.ui,
I could try building it.
Which version of Qt is this? On which platform?

Oh...I deleted the spaces in the postings which threw the line numbers out.
This is line 9:
class SortDialog : public QDialog, public Ui::SortDialog

I've emailed the ui file to you, the only other source files are main.cpp,
sortdialog.cpp and sortdialog.h which are in the body of my posting.

And as Stephen already said: There's your problem. The class entry is
set in designer via the name of the form itself and will be used as
classname for the class in the Ui namespace. A slight copy error on
your side, rename the Form object to SortDialog and it should work. Or
change the subclassing line to Ui::sortDialog.

that was the problem...I'll have to get used to case-sensitive filenames
under linux :-()

Its not about the filename. C++ class names are case-sensitive on all
systems. From the .ui file a C++ class is generated and the class name
is the same as the name of the top-level form (not the title). Thats why
you need to use the same class name for the subclass.

I have the book and have copied the files from cd
(examples/chap02/sort). It builds and runs fine for me:
Ubuntu Edgy, gcc 4.1.2, Qt 4.2.1 (compiled by me).
I cannot spot anything obviously wrong in what you posted.
However, I can reproduce the error message by editing sortdialog.ui (in
designer or otherwise) and misspelling SortDialog as sortdialog. If you
have copied it off the cd you won't have this problem, but perhaps this
might point you in the right direction.
Hope this helps,
