What version of macOS are you on? And which compiler do you use? |

This is incompatibility between upstream clang and Apple's headers. The same warning is not present when using Xcode's compiler. As a workaround this warning can be disabled when including pthread.h, something like: ``` #ifdef __clang__ #pragma clang diagnostic push #pragma clang diagnostic ignored "-Wexpansion-to-defined" #endif #include <pthread.h> #ifdef __clang__ #pragma clang diagnostic pop #endif ``` I won't create a PR for this because I don't have homebrew on my systems. Alternatively build with "-Wno-expansion-to-defined" in CFLAGS. |
