This usually means that your header search paths are not configured properly. The header search paths should contain the C++ Standard Library headers before any C Standard Library, and you are probably using compiler flags that make that not be the case. 2026-03-13T09:48:57 | 149 | # error <cstdint> tried including <stdint.h> but didn't find libc++'s <stdint.h> header. \
