Ich versuche, ein Javafx-Beispiel auf einem Himbeer-Pi 3 in einer eingebetteten Umgebung (Buildroot) auszuführen. Ich möchte es ohne X ausführen, wenn ich den Befehl ausführe:
/root/jre-13.0.1/bin/java -Dfile.encoding=UTF-8 --add-modules javafx.controls,javafx.fxml -Dprism.verbose=true -Djavafx.verbose=true -Dglass.platform=Monocle -Dprism.order=es2 -Djava.library.path=/root/jre-13.0.1/lib/ -Dembedded=monocle -jar /home/root/NetBeansProjects//JavaFXFXML/dist/JavaFXFXML.jar
Ich bekomme folgenden Fehler:
cmd : cd '/home/root/NetBeansProjects//JavaFXFXML'; '/root/jre-13.0.1//bin/java' -Dfile.encoding=UTF-8 --add-modules javafx.controls,javafx.fxml -Dprism.verbose=true -Djavafx.verbose=true -Dglass.platform=Monocle -Dprism.order=es2 -Djava.library.path=/root/jre-13.0.1/lib/ -Dembedded=monocle -jar /home/root/NetBeansProjects//JavaFXFXML/dist/JavaFXFXML.jar

Ich habe die Beispiele hello_triangle und hello_dispmanx ausgeführt, um die GPU-Beschleunigung zu testen, und dort gab es keine Probleme. Ich weiß nicht, warum ich den Could not get EGL surface
Fehler erhalte. Gibt es eine Möglichkeit, diesen Fehler zu debuggen?
