我目前正在尝试在我的 Raspberry Model B+ v1.2 上部署我的 JavaFX 应用程序，它可以在 Windows 上顺利运行。由于 JavaFX 不能直接在 Raspi 上使用，因此我按照此处所述使用 Gluon 进行了改编(但使用最新版本 144):Running Javafx GUI on the Raspberry Pi
现在，当我运行仅显示一个简单窗口的 JFX 应用程序时，我收到以下有关着色器问题的错误堆栈(加载库存着色器 AlphaTexture_Color 时出错):

会不会是我的树莓派太老了，硬件上不支持某些着色器？ 我还能尝试什么？
非常感谢!
最佳答案
Hmpf，真是巧合，我发现了这一点……问题出在 VRAM 上!它必须在树莓上从 64mb 增加到 128 或 256 才能工作。这可以通过 raspi_config 或可视化配置界面来完成。
关于树莓派上的 JavaFX : Error loading stock shader，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45377127/
