C++ 节点expat错误的ELF类：ELFCLASS64

我必须在构建机器上构建我的节点应用程序，然后将该应用程序移到目标机器上，因为我无法按照某些依赖性的要求在目标机器上编译C

我在node expat中遇到了一个编译错误，这导致了上面的ELF类错误。我曾尝试在32位和64位版本的linux上重建我的节点应用程序，但当我将其移植到目标机器（应该是64位机器）时，它似乎解决了这个问题

我在构建时遇到以下错误：

尽管它在我正在构建的机器上运行良好。当我尝试在我的目标机器上运行它时，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libs或32位libs？我可以通过node gyp/npm强制node expat使用正确的libs进行编译吗

ELFCLASS64

是否告诉我应用程序正在尝试调用64位libs或32位libs

它告诉您一个32位进程试图打开一个64位库

从您的描述中不清楚如何调用

节点

，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

您需要调用64位二进制文件，或者以32位模式构建库
