When I use compound literals like
#define VECTOR_ROOT_E131_DATA (uint8_t[]){0x00, 0x00, 0x00, 0x04}
I get following error message:
lib/sACN/src/sACNDefs.h:76:42: error: taking address of temporary array
76 | #define VECTOR_ROOT_E131_DATA (uint8_t[]){0x00, 0x00, 0x00, 0x04}
The compound literals works fine when using code runner on macOS with clang.
