This is one of a lot bindgen issues related to libclang and particularly cross compiler config.

You can try either of the following:

• Add path to llvm-config in your android ndk toolchain to PATH env var and set HOST_CC= with path to host clang.
• Set env var LIBCLANG_PATH= with path to libclang.so in your android ndk toolchain.

In any case I recommend use pre-generated bindings.

Add path to llvm-config in your android ndk toolchain to PATH

was helpful, thank you.

I can not solve this issue with above methods. I set BINDGEN_EXTRA_CLANG_ARGS=-I/path/to/folder/containing/cstdint to solve the issue.

@chengchangwu Thanks. Can we create PR to add this workaround to readme and docs?

[chengchangwu]

OK, I will create a PR.
