JNativeHook 中的编译失败

Question

试图编译这个https://github.com/kwhat/jnativehook/wiki/Compiling

做到了我必须运行 ant all 来构建的步骤。

编译失败并在命令提示符中显示以下内容。

    [javac] Fatal Error: Unable to find package java.lang in classpath or bootcl
asspath

BUILD FAILED
C:\Users\George\Downloads\sounds\JNativeHook-2.0.1\JNativeHook\build.xml:394: Co
mpile failed; see the compiler error output for details.

编辑：我刚刚将 rt 文件复制到我要编译的目录中。我克服了第一个错误，但现在我得到了

与此同时，仍在努力解决这个问题。

更新：

我想我一直在处理这个错误。我尝试在 MINGW64 中这样做，这可能是我应该这样做的。

遗憾的是，我仍在调查一个错误。

更新：

哇，msys64 有多少个 shell。我现在已经尝试了似乎是最后一个也是最后一个 shell msys2_shell.bat 并且它得到了更进一步但仍然失败。

现在我明白了

如此接近。

更新：

已安装 clang，现在从 config.log 文件中获取此详细错误。

Answer 1

好吧，对于像我这样在 Windows 8.1 上执行此操作的未来 JNativeHook 编译器新手来说，我必须这样做才能使其正常工作。

除了遵循 git 上提供的 compile for windows 部分中的所有步骤。

你还需要...

下载适用于 Windows 的 LLVM。 将您的 rt.jar 复制到 JNativeHook 目录中。 并确保绝对确保您已删除从失败的构建生成的任何 build.properties。

这应该可以正常工作。

Answer 2

如果您尝试编译 2.0.1，请不要忘记运行 ant distclean first。我忘记将 build.properties 文件包含在 zip 文件的排除列表中，从而搞砸了打包过程。我认为这也将解决您的 rt.jar 复制问题。它可能会解决您的所有问题；）无论如何，2.0.2 将解决问题并计划在周日发布。
