我尝试在raspberry PI3B+上使用javafx应用程序,并将一个小的显示器连接到显示端口。但这会在启动应用程序时引发错误。
也许首先要问几个问题:
javafx是否支持显示端口?因为这是我第一次用它代替hdmi。
或者openjfx16ea只适用于树莓pi 4?
我从下载了最新的openjfxhttps://gluonhq.com/products/javafx/.
这是我运行(maven)编译的应用程序的启动命令:
sudo java -Dmonocle.egl.lib=/opt/arm32fb-sdk/lib/libgluon_drm.so \
-Djava.library.path=/opt/arm32fb-sdk/lib \
-Dmonocle.platform.traceConfig=true \
-Dmonocle.platform=EGL \
-Dprism.verbose=true \
-Djavafx.verbose=true \
-p /opt/arm32fb-sdk/lib \
--add-modules javafx.controls \
-jar javafx-ui-1.0.0-SNAPSHOT-jar-with-dependencies.jar
这是错误输出:

我好像有两个问题:
我从没有桌面的raspberry lite操作系统开始,所以首先必须安装x11
2-对于覆盆子pi 3,不应使用单片眼镜,而应使用gtk。此开始脚本工作:

javafx的16个ea版本也应该可以在pi3(以及其他一些基于arm的系统)上使用。但是,您必须使用的单片眼镜平台取决于系统上安装的驱动程序。如果您选择带有drm库的egl平台,您的系统需要具有所需的库(例如libgbm.so),这些库与pi4和最新的raspberry pi os一起预装。
如果您使用的是窗口管理器,则不应使用monocle,但gtk:
-dglass.platform=gtk
