I know this isn't fbsd specific but...
i'm tryin to follow a qt tutorial to get started with the qt libraries.
when tryin to compile 'hello world' :
--snip--
#include <qapplication.h>
#include <qpushbutton.h>
int main( int argc, char **argv )
{
QApplication a( argc, argv );
QPushButton hello( "Hello world!", 0 );
hello.resize( 100, 30 );
a.setMainWidget( &hello );
hello.show();
return a.exec();
}
--snip--
i get this:
--snip--

i've looked in my -I arg dir and it DOES contain the .h files in the
source.
what gives?
