native-image says "unknown type name 'uint8_t'" during compilation

Question

I'm getting this error:

$ native-image -jar foo.jar bin/java-Objects.bin
...
[bin/java-Objects.bin:24855]    classlist:   1,143.29 ms,  0.96 GB

error: unknown type name 'uint8_t'

I'm with Clang:

$ clang --version
Homebrew clang version 13.0.0
Target: x86_64-apple-darwin20.6.0
Thread model: posix
InstalledDir: /usr/local/opt/llvm/bin

It seems that the problem is with this code in sys/resource.h:

#if __DARWIN_C_LEVEL >= __DARWIN_C_FULL
#include <stdint.h>
#endif /* __DARWIN_C_LEVEL >= __DARWIN_C_FULL */

This line with stdint.h doesn't get included and that's why uint8_t doesn't get defined.

Do you know if '__DARWIN_C_LEVEL >= __DARWIN_C_FULL' is true? — RobbingDaHood, Jan 24 '22 at 19:01
Could you share a working simple example that gives this error when you compile? — RobbingDaHood, Jan 24 '22 at 19:01
@RobbingDaHood obviously, it's not true. That's why the `stdint.h` is not loaded :( — yegor256, Jan 26 '22 at 12:38
what if you roughly remove the condition, and import it whatever..? — assayag.org, Jan 27 '22 at 02:34
@RobbingDaHood this is my code: [`Objects.java`](https://github.com/yegor256/fibonacci/commit/fe849f486b1ac8eef1f3e992d655bcfd131f0a36#diff-a80da4b27a0b8498a0819fc59738e3dce9b2ef4a60431155fc1206d7bfb9bfab) — yegor256, Feb 05 '22 at 06:29

Possible solution

Please, consider trying to follow the instruction from quarkus/faq.adoc at main · quarkusio/quarkus:

1. Native compilation

Native executable fails on macOS with error: unknown type name 'uint8_t'

Your macOS has the wrong *.h files compared to the OS and no gcc compilation will work. This can happen when you migrate from versions of the OS. See Cannot compile any C++ programs; error: unknown type name 'uint8_t'

The solution is to

sudo mv /usr/local/include /usr/local/include.old

Reinstall XCode for good measure

(optional?) brew install llvm

generally reinstall your brew dependencies with native compilation

The executable should work now.

The purpose of (the idea behind) renaming the include directory (from include to include.old) seems to be explained in the answer.
