Is it available to build in MacOS M1?

When I build c file to html, I meet this problem

factorial.c:16:10: fatal error: 'Python.h' file not found
   16 | #include "Python.h"
      |          ^~~~~~~~~~
1 error generated.
emcc: error: '/Users/xxxx/code/emsdk/upstream/bin/clang -target wasm32-unknown-emscripten -fignore-exceptions -mllvm -combiner-global-alias-analysis=false -mllvm -enable-emscripten-sjlj -mllvm -disable-lsr --sysroot=/Users/xxxx/code/emsdk/upstream/emscripten/cache/sysroot -DEMSCRIPTEN -Werror=implicit-function-declaration -Xclang -iwithsysroot/include/fakesdl -Xclang -iwithsysroot/include/compat factorial.c -c -o /var/folders/_z/n8npvx457n7_9qb_qgxx80jr0000gn/T/emscripten_temp_xmn02nn3/factorial_0.o' failed (returned 1)

I found I should install python-dev on mac computer, But I always buid fail. It seems like building issue, I don't know this is my problem or platform problem. I want to know is it essential for me to change a linux or windown platform if I want to use wasm and emscripten smoothly?

install method: python3 -m pip install python-dev-tools --user --upgrad

  note: This error originates from a subprocess, and is likely not a problem with pip.

If you want to build code that uses Python.h with emscripten then you would first need to build and install the python libraries and headers using emscripten and put them somewhere where emcc can see them. You can't use the python libraries and headers that come with your host OS.

You can either install the headers and libraries into the emscripten sysroot, or you can use -I and -L flags to point emcc at the headers and libraries you have built.

-I works for this problem, Thanks very much.

But I met another problem

/opt/homebrew/opt/[email protected]/Frameworks/Python.framework/Versions/3.12/include/python3.12/pyport.h:586:2: error: "LONG_BIT definition appears wrong for platform (bad gcc/glibc config?)."

Most solution after google search are incorrect bit-variation of python, but I found mine is correct(64-bit), it's wired.

$ file /opt/homebrew/opt/[email protected]/Frameworks/Python.framework/Versions/3.12/bin/python3
/opt/homebrew/opt/[email protected]/Frameworks/Python.framework/Versions/3.12/bin/python3: Mach-O 64-bit executable arm64

The header file in question looks like it is from homebrew which means it is likely built for your host OS and not for emscripten: /opt/homebrew/opt/[email protected]/Frameworks/Python.framework/Versions/3.12/include/python3.12/pyport.h

The headers in /opt/homebrew cannot be used with emscripten.

Got it. Thanks.
For another solution, what I should do to install the headers and libraries into the emscripten sysroot, I check the document of emcc, I didn't find related method...

The first step you you likely need to take is to build python (or at least the python libraries and headers) using emscripten. See https://stackoverflow.com/questions/44761748/compiling-python-to-webassembly for example.
