wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch)
提问by
I have this strange exception saying wrong ELF class but the wrapper is set correctly.
我有一个奇怪的异常，说 ELF 类错误，但包装器设置正确。

It doesn't work because you're using a 64-bit version of Java, and the SDK you're trying to use contains a 32-bit native library (libbeidlibJava_Wrapper.so.3.5.3). The 64-bit JRE cannot load 32-bit native libraries.
它不起作用，因为您使用的是 64 位版本的 Java，而您尝试使用的 SDK 包含一个 32 位本机库 ( libbeidlibJava_Wrapper.so.3.5.3)。64 位 JRE 无法加载 32 位本机库。
You'll need to use a 32-bit version of Java, or find a version of the SDK that has 64-bit native libraries.
您需要使用 32 位版本的 Java，或者找到具有 64 位本机库的 SDK 版本。
