Are you using Linux or Windows? Use Windows. Don't use Linux. There is a missing symbol error from ld linker after entry start. In this case the software doesn't seem to be installed correctly. Then if you slightly further up it clearly states building for macOS-x86_64 but attempting to link with file built for unknown-arm64 followed by ld: warning: ignoring file There. You see that? Your problem seems to be that you do not have the macOS-x86_64 software required. It tried to do its best to build despite you not having the correct libraries before giving up because it failed to find the first symbol from the entry point.
