JavaFXPorts（Gluon）在Raspberry Pi上安装并运行一个简单的JFX程序

提问于

My Hardware:

My Software:

  • 操作系统：Raspbian GNU / Linux 8（jessie Lite）[Ohne X]

  • 内核：Linux 4.4.21

  • 建筑：手臂

  • 触摸显示和Hifiberry通过设备树覆盖激活

  • Java：jdk-8u121-linux-arm32-vfp-hflt

  • JavaFXPorts（Gluon）：JavaFX Embedded SDK Version 8.60.8 armv6 hard float

What I have done so far:

首先，我从Oracel klick下载了当前的JDK版本（适用于Linux ARM 32 Hard Float ABI的Java 8u121） .

我打开了所有包装 /opt/

接下来我安装了新的Java版本......

sudo update-alternatives --install "/usr/bin/java" "java" "/opt/jdk1.8.0_121/bin/java" 1
sudo update-alternatives --install "/usr/bin/javac" "javac" "/opt/jdk1.8.0_121/bin/javac" 1


sudo update-alternatives --set "java" "/opt/jdk1.8.0_121/bin/java"
sudo update-alternatives --set "javac" "/opt/jdk1.8.0_121/bin/javac"

当我现在进入 java -version

pi@raspberrypi:/opt $ java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) Client VM (build 25.121-b13, mixed mode)

到目前为止看起来不错，不是吗？

其次，我从Gluon klick下载了当前版本的JavaFXPorts（JavaFX Embedded SDK Version 8.60.8 armv6 hard float） .

我将以下文件复制到JDK目录（/opt/jdk1.8.0_121），如2.1.4中here所述 .

我希望我在所有复制的文件上添加了正确的访问权限和组成员身份？

如上所述，我使用Raspbian Lite，其中缺少Pango包 . 我已经阅读过OpenJFX klick . 所以我安装了它

sudo apt-get install libpango-1.0-0:armhf libpangoft2-1.0-0:armhf

作为编程环境，我在家用电脑上运行 Netbeans 8.2 .

首先，我制作了一个正常的“Hallo World”程序，这在Raspberry Pi上非常有用 .

然后在家用电脑上用Netbeans构建一个非常简单的JavaFX Programm并转移到Raspberry Pi（到目录：/ home / pi / Netbeans）

使用命令 sudo java -jar JavaFXbasic.jar 从我的家用PC通过SSH执行

And I always see this Error on the Raspberry Pi ...（ Note: .jar-File正在我的家用电脑上工作！）

我真的不明白来自Java的错误信息...我认为我做错了什么或忘了安装JavaFXPorts的东西？

我的系统现在如何知道OpenJFX？我没有运行任何安装命令或类似的...或编辑类路径 .

谢谢阅读
