And then

/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/errno.h is exits.

I had tried more way, but the problem still exists.

export CFLAGS="-I /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include"
export CXXFLAGS="-I /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include"
export CCFLAGS="-I /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include"

You can try which clang to check if you are using the clang provided in CommandLineTools

You can try create a tmp.c:

#include<errno.h>

int main() {
    return 0;
}

Then run clang tmp.c -v to see the searched include path of your clang. Here is the output on my macOS machine:

You can check if /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include printed. If not, try reinstall the CommandLineTools or provide the include path with environment variable manually (ref).

I had reinstall command line tools. But not work too.

Maybe it's because my ffmpeg is not with brew? I don't like to use brew. I will use the virtual machine to test later

Nope, the FFmpeg provided by homebrew is outdated(which has linking issues in my previous experience) and un-customizable, people should always build ffmpeg with source code.

As your log shows that /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include is searched, I think your clang is correctly configured.

clang-sys is used bindgen(dependency of rusty_ffmpeg) to find out the libclang.dylib on macOS. Please try cargo clean and run export LIBCLANG_PATH=/Library/Developer/CommandLineTools/usr/lib before building to explicitly provide the path of libclang.dylib(ref). You might not be using the libclang.dylib provided by the official CommandLineTools. :-(

You can contact me with QQ Mjk5MzU5MzgwNQ== if the problem persists.

LIBCLANG_PATH=/Library/Developer/CommandLineTools/usr/lib

Good job, the problem is solved after delete llvm path from environments.

export LIBCLANG_PATH=/Library/Developer/CommandLineTools/usr/lib is no effect.

(Just reply to the method you provided. My environment variables are set unreasonably)

my .zshrc

export LLVM_HOME=$RUNTIMES_DIR/llvm
export PATH=$PATH:$LLVM_HOME/bin
export LIBRARY_PATH=$LIBRARY_PATH:$LLVM_HOME/lib
export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:$LLVM_HOME/lib
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$LLVM_HOME/lib
