Pi 3上的OpenJFX 16ea为libprism_es2_monocle.so抛出UnsatisfiedLinkError:libGLESv2.so [英] OpenJFX 16ea on Pi 3 throws UnsatisfiedLinkError for libprism_es2_monocle.so: libGLESv2.so

问题描述

我尝试在Raspberry Pi 3 B +上使用JavaFX应用程序，并将小显示屏连接到显示端口.但这会在应用程序启动时引发错误.

I try to use a JavaFX application on a Raspberry Pi 3 B+ with a small display connected to the display port. But this throws an error on startup of the application.

也许首先是一些快速入门的问题:

Maybe first some quick questions to get started:

• JavaFX是否支持显示端口?因为这是我第一次使用它而不是HDMI.
• 或者OpenJFX 16ea仅适用于Raspberry Pi 4?

我从 https://gluonhq.com/products/javafx/下载了最新的openjfx.

I downloaded latest openjfx from https://gluonhq.com/products/javafx/.

这是我的启动命令，用于运行(Maven)已编译的应用程序:

This is my startup command to run the (Maven) compiled application:

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:

推荐答案

似乎我遇到了两个问题:

Seemed I was having two problems:

1-我从没有桌面的Raspberry Lite操作系统开始，所以首先必须安装X11

1 - I started with a Raspberry Lite OS without Desktop, so first had to install X11

$ sudo apt install xserver-xorg
$ sudo apt install raspberrypi-ui-mods
$ sudo apt install lightdm
$ sudo reboot

2-对于Raspberry Pi 3，不应该使用Monocle，而应使用GTK.此启动脚本有效:

2 - For the Raspberry Pi 3 not Monocle should be used, but GTK. This start script works:

sudo java \
  -Dglass.platform=gtk \
  -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
