节点外派错误的ELF类:ELFCLASS64

Node-expat wrong ELF class: ELFCLASS64

本文关键字：ELFCLASS64 ELF 错误 节点      更新时间：2023-10-16

我必须在构建机器上构建我的节点应用程序，然后将应用程序移动到目标机器上，因为我无法按照某些依赖项的要求在目标机器上编译 C。

我在 node-expat 上遇到了编译错误，它吐出了上述 ELF 类错误。我尝试在 32 位和 64 位版本的 linux 上重建我的节点应用程序，尽管当我将其移植到目标机器（据说是一台 64 位机器）时似乎解决了这个问题。

我在构建时收到这些错误：

尽管它在我正在构建的机器上运行良好。当我尝试在目标计算机上运行它时，我得到以下结果：

ELFCLASS64是否告诉我应用程序正在尝试调用 64 位库或 32 位库？我可以通过node-gyp/npm强制node-expat使用正确的库进行编译吗？

ELFCLASS64是否告诉我应用程序正在尝试调用 64 位库或 32 位库？

它告诉您 32 位进程试图dlopen 64 位库。

从您的描述中不清楚您如何调用 node ，但您在目标计算机上调用的二进制文件是 32 位二进制文件，无法加载 64 位共享库。

您需要改为调用 64 位二进制文件，或者在 32 位模式下构建库。
