c++ - 使用Emscripten将C ++文件转换为wasm时出错(Error converting c++ file to wasm using emscripten)

Question

This is a follow up question from this post Converting .cpp file to .wasm file

(这是本文将.cpp文件转换为.wasm文件的后续问题)

I'm trying to convert my c++ file into .wasm using emscripten on linux.

(我正在尝试在Linux上使用emscripten将c ++文件转换为.wasm。)

I'm running into this error:

Can someone help

(有人可以帮忙吗)

Answer 1

You can't/shouldn't include x86intrin.h when building for WebAssembly.

(在构建WebAssembly时，您不能/不应该包含x86intrin.h 。)

It looks like you need to build without SEAL_USE_INTRIN : https://github.com/microsoft/SEAL/blob/master/native/src/seal/util/clang.h#L18

(看来您需要在没有SEAL_USE_INTRIN情况下进行构建： https : //github.com/microsoft/SEAL/blob/master/native/src/seal/util/clang.h#L18)
