java - JCEF ICU检查失败

我似乎不断地碰壁，使 Chrome 与JCEF一起运行。我可以找到本机函数，但仍然无法完成初始化。我设置了LD_PRELOAD变量。我同时运行MainFrame.java类和自定义Scala代码，并且在每一个中都遇到相同的问题。有办法解决吗？

系统:

操作系统:Ubuntu 16.04

JCEF版本3

CEF版本3

Java Jdk 8

结构和配置:

一切都在二进制分布结构下。我将jars作为库导入，将本机库路径添加到jcef jar中，并将其导入到我的项目中。

我使用环境变量设置运行配置:

显示=:0.0

LD_PRELOAD = /path/to/libcef.so

我所有的库和* .pak文件都与chrome沙箱和助手位于同一个目录中，以及libcef.so所在的子目录(二进制发行版)中。

代码和错误

代码在执行以下操作后失败:

  println("Generating Handlers")
  CefApp.addAppHandler(Handlers.getHandlerAdapter)
  private var settings = new CefSettings
  settings.windowless_rendering_enabled = useOSR
  println("Starting App")
  private final val cefApp : CefApp = if(commandLineArgs != null && commandLineArgs.size > 0) CefApp.getInstance(ChromeCommandLineParser.parse(commandLineArgs)) else CefApp.getInstance(settings)
  println("Creating Client")
  private final val client : CefClient = cefApp.createClient()

输出结果如下:

感谢所有帮助。谢谢

最佳答案

我也有很多问题，直到我在"icudtl.dat"而不是"natives_blob.bin"下创建到"snapshot_blob.bin"，$jdk/bin directory和$jdk/jre/bin的符号链接。

现在，我不再收到此错误。

在https://bitbucket.org/chromiumembedded/java-cef/wiki/BranchesAndBuilding中使用示例

我改变了这个...

$ sudo ln -s /path/to/java-cef/src/third_party/cef/linux64/Resources/icudtl.dat /usr/lib/jvm/java-8-oracle/jre/bin/icudtl.dat

$ sudo ln -s /path/to/java-cef/src/third_party/cef/linux64/Debug/natives_blob.bin /usr/lib/jvm/java-8-oracle/jre/bin/natives_blob.bin

$ sudo ln -s /path/to/java-cef/src/third_party/cef/linux64/Debug/snapshot_blob.bin /usr/lib/jvm/java-8-oracle/jre/bin/snapshot_blob.bin

为此...

$ sudo ln -s /path/to/java-cef/src/third_party/cef/linux64/Resources/icudtl.dat /usr/lib/jvm/java-8-oracle/bin/icudtl.dat

$ sudo ln -s /path/to/java-cef/src/third_party/cef/linux64/Debug/natives_blob.bin /usr/lib/jvm/java-8-oracle/bin/natives_blob.bin

$ sudo ln -s /path/to/java-cef/src/third_party/cef/linux64/Debug/snapshot_blob.bin /usr/lib/jvm/java-8-oracle/bin/snapshot_blob.bin
