It's hard to say further without having the code you're
compiling, but my best guess is that the C preprocessor is stuck
on this or similar:
https://clang.llvm.org/doxygen/____stddef__size__t_8h_source.html
```
/*
* When -fbuiltin-headers-in-system-modules is set this is a
non-modular header
* and needs to behave as if it was textual.
*/
#if !defined(_SIZE_T) ||
\
(__has_feature(modules) &&
!__building_module(_Builtin_stddef))
#define _SIZE_T
```
Without more information I can't give any specific advice, but
the answer may be to pass something to the preprocessor using -P
in your compilation command as described here:
