another QT3 problem
 

I am trying to learn some programming with QT3. I have the book C++ GUI Programming with QT3. I did the first program "hello" and the first time I ran it everything worked as expected but now I get:

[dad@localhost hello]$ ./hello.cpp
./hello.cpp: line 3: syntax error near unexpected token `('
./hello.cpp: line 3: `int main (int argc, char *argv[])'

I didn't do anything to the program and now I also get this with the next simple program called quit.

Hello:

#include <qapplication.h>
#include <qlabel.h>
int main (int argc, char *argv[])
{
QApplication app(argc, argv);
QLabel *label = new QLabel("Hello Qt!", 0);
app.setMainWidget(label);
label->show();
return app.exec();
}

Quit:
#include <qapplication.h>
#include <qpushbutton.h>

int main (int argc, char *argv[])
{
QApplication app(argc, argv);
QPushButton *button = new QPushButton("Quit", 0);
QObject::connect(button, SIGNAL(clicked()),
&app, SLOT(quit()));
app.setMainWidget(button);
button->show();
return app.exec();
}

[dad@localhost quit]$ ./quit.cpp
./quit.cpp: line 4: syntax error near unexpected token `('
./quit.cpp: line 4: `int main (int argc, char *argv[])'

The thing that gets me is it worked once and now I get these errors.

I sure would appreciate any help.

Thanks,
Sal

the only thing i can think of is these files have been on a ms computer ?
and that ms newline think is confusing the compiler

No they have not been on an MS machine. I even deleted the files and started from scratch. Same result

Why are you trying to run the source file? :/

Because the second time I ran it I had deleted all the files and redid the hello.cpp. then I typed "qmake -project", then "qmake hello.cpp" and then DID NOT type "make" so typing ./hello produced nothing. Typing ./hello.cpp at least gave me something. Thanks for helping me find my mistake. It works great when you make the executable.
