title: Qt: My Application doesn't show up in my enterprise HW while in pc does
body: <p>I've made a couple of projects in Qt4.8.5 which have to run on a especific device (the product of our company) which runs under a unix OS and they run normal. You launch them, they show up and you use them.</p>
  
  <p>Now I've made another program, which is like one of the before mentioned but bigger. The thing is that now that I've finished it, I've tried to run it on the HW and something strange happened:</p>
  
  <p>The screen gets black (the tipical black "with light" that means that the screen is on). I've launched it manually so I can see the console messages on console and I see all the qDebug() it has to print at the beginning and also, I have a <code>qDebug() &lt;&lt; "1st page";</code> on the <code>::initializePage()</code>funcion of the first page shown (is a QWizardPage) also which is printed, so everything looks normal but... I can't see it on the screnn... just a black screen (My apps' background is orange so it is now the background of the app).</p>
  
  <p>Any idea of why I can't see it? The HW has all the libraries necessaries for it because as I said, I run there  2 other Qt apps.</p>
  
  <p>I add my .pro info...don't think it is usefull now but... any information is apreciated I guess..</p>
  
  <pre><code>QT       += core gui
  QT       += network
  QT       += script
  QT       += date
  QT       += time
  QT       += xml
  QMAKE_CXXFLAGS += -std=c++11
  QMAKE_CXXFLAGS  += -s
  
  greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
  
  TARGET = MyApp
  TEMPLATE = app
  </code></pre>
  
  <p>Thank you so much.</p>
  
  <p><strong>Note:</strong> In the 1st page I have 2 buttons, so if you press enter, you go to the next QWizardPage called 2nd page so... when I see the "1st page" message on console, if I press enter on the device, of course, it then shows the "2nd page" message from the qDebug in the ::initializePage() which means that the program runs well, it is not frozen.</p>
  
  <p>Another thing I want to point is that: it  CAN'T be in the background running, the device make it appear in front always.</p>
