Why Qt can not find a public slot?

[Alex Snet]

Like this?

using namespace qmapcontrol;
class mwnd : public QWidget
{
    Q_OBJECT
public:
    mwnd(QWidget* parent = 0);
    ~mwnd();

using namespace qmapcontrol;
class mwnd : public QWidget
{
    Q_OBJECT
public:
    mwnd(QWidget* parent = 0);
    ~mwnd();

If I write this - I recieve this:

:-1: error: collect2: ld returned 1 exit status

:-1: error: collect2: ld returned 1 exit status

can you post the whole error? this is just linker stopping cuz of some error that occured before

[Alex Snet]

Sorry, I don't understand.
I write all I have... Where is my bad?

you have to rebuild your app after adding Q_OBJECT macro.
so, do this

make/mingw32-make/nmake clean
qmake
make/mingw32-make/nmake

[Alex Snet]

Rebuilding and cleaning does not help =(

Why the compiler can not find the socket if it was declared?

[spirit]

can you attach compilable example?

[Alex Snet]

Problem is solved. Thank you!
It's realy my bad. When I cleaning up my project from terminal (qmake clean) some files are missed and doesn't deleted. And when I cleaning by myself - application start's normaly.

(qmake clean)

Typo? It has to be make clean!
