greetings everyone!
i am currently working on getting ROOT to interface with QT, the the primary goal of having a QT gui display ROOT histograms and the like. I have read the chapter in the users guide about doing this and have successfully installed a local version of QT 4.6.3 and ROOT 5.24 (with both qt and qtgsi enabled).
I am trying to get the following example (which is found in the users guide) to compile and run.
[code]// Minimal ROOT based Qt example
#include <qapplication.h>
#include
#include <TGraph.h>
#include <TQtWidget.h>
#include <TCanvas.h>
#include <TQtRootApplication.h>
int main( int argc, char **argv ) {
QApplication *app = new QApplication(argc, argv);
TQtWidget *MyWidget= new TQtWidget(0,“MyWidget”);
// Create any other Qt-widget here
MyWidget->show();
MyWidget->GetCanvas()->cd();
TGraph *mygraph;
float x[3] = {1,2,3};
float y[3] = {1.5, 3.0, 4.5};
mygraph = new TGraph(3,x,y);
mygraph->SetMarkerStyle(20);
mygraph->Draw(“AP”);
MyWidget->GetCanvas()->Update();
app->exec();
return 0;
}[/code]
here is my .pro file

this compiles fine, but when i run it, it opens cint, and then segfaults. that's when i realized i hadn't compiled qtcint. i am assuming this is the problem... alas, qtcint will not compile ...
here is the output from gmake qtcint...

I’ll let you know when qtcint works with Qt 4.6.3.
