Error when trying to compile into wasm, why?

Question

I wrote a code that is compiled into wasm with rust, which includes the pfx file added when reqwest requests, but it prompts openssl error when compiling. What is the reason please?

error: failed to run custom build command for `openssl-sys v0.9.77`

Caused by:

What file is inttypes.h and how can I change it so that it can be found ?

It looks like you have some incorrect include paths in your build.

The headers that live in /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain are almost certainly not going to be compatible with a WebAssembly toolchain such as emscripten or wasi-sdk. I would advice you to find out where they are getting injected and remove them. It seems like you the software you are building might be need more configuration to know that you are trying to cross compile to wasm.
