C++ 转换c+时出错+；使用emscripten将文件发送到wasm

这是本帖的后续问题

我试图用Linux上的ESPRINTEN将我的C++文件转换成.WASM。我遇到了以下错误：

有人能帮忙吗

在构建WebAssembly时，您不能/不应该包含

x86intrin.h

。看起来您需要在不使用

SEAL\u-USE\u-INTRIN的情况下进行构建：
我已经能够使用带intrinsic的emscripten（
#include
）将Microsoft SEAL库编译为WebAssembly，但这是可选的

工具链本身从来没有给我这个特定的错误，因为
emcmake
步骤总是无法找到必要的头并在没有优化的情况下编译

听起来您可能没有使用适当的
emcmake
或
em++
参数。此外，如果您想使用intrinsic，则需要gcc.h和clang.h（位于SEAL/native/src/SEAL/util/）中的一些条件来使用
wasm_simd128.h
over
x86intrin.h

请随意查看我的实现和/或在Mac和Linux（Ubuntu）上编译的构建脚本：

如果您只需要一个工作库，也可以下载npm软件包：
ia32说所有的体系结构都是混合的。@Lee抱歉，你能再解释一下吗？关于_builtin_ia32*文档说：“这些内置函数可用于i386和x86-64系列计算机，具体取决于所使用的命令行开关。”但是您正在编译到wasm，因此这些函数不应该存在于此上下文中。@Lee您是否知道解决此问题的方法？我会放弃emscripten而使用其他东西吗？我有点迷路了。我从未使用过sealdemo.cpp，但我认为最好从那里开始，或者在设置的地方使用一些编译器标志。但是你的日志中没有包含这方面的信息。
