objdump seems to always print an error message, example: malcolm@Malcolms-Air keeperfx % objdump --version Apple LLVM version 13.0.0 (clang-1300.0.29.30)  Optimized build.  Default target: arm64-apple-darwin21.3.0  Host CPU: vortex  Registered Targets:   aarch64  - AArch64 (little endian)   aarch64_32 - AArch64 (little endian ILP32)   aarch64_be - AArch64 (big endian)   arm    - ARM   arm64   - ARM64 (little endian)   arm64_32  - ARM64 (little endian ILP32)   armeb   - ARM (big endian)   thumb   - Thumb   thumbeb  - Thumb (big endian)   x86    - 32-bit X86: Pentium-Pro and above   x86-64   - 64-bit X86: EM64T and AMD64 malcolm@Malcolms-Air keeperfx % clang --version Apple clang version 13.0.0 (clang-1300.0.29.30) Target: arm64-apple-darwin21.3.0 Thread model: posix InstalledDir: /Library/Developer/CommandLineTools/usr/bin malcolm@Malcolms-Air keeperfx % clang -c src/actionpt.c In file included from src/actionpt.c:19: In file included from src/actionpt.h:22: src/bflib_basics.h:153:15: warning: '__stdcall' calling convention is not supported for this target [-Wignored-attributes] typedef void (__stdcall *TbNetworkCallbackFunc)(struct TbNetworkCallbackData *, void *);        ^ 1 warning generated. malcolm@Malcolms-Air keeperfx % objdump -f actionpt.o  actionpt.o: file format mach-o arm64 /Library/Developer/CommandLineTools/usr/bin/objdump: error: 'actionpt.o': Invalid/Unsupported object file format The warning message should have no impact on objdumps ability to produce a result. I have been looking for objcopy as I need to rename some functions in a precompiled library. I installed the gnu binutils version (brew install binutils) .. this generates a file that the gnu binutils thinks is perfect. The Apple objdump throws up error messages.
