I found this was an issue with Homebrew binutils package conflicting with XCode. For more info, see https://stackoverflow.com/a/43452124/1715495.

brew unlink binutils && make clean && make did the trick for me.

@dhalperi many thank. It works well

[hnishi]

dhalperi's answer did not work for me.
but if binutils was uninstalled instead of unlink, it worked for me.

brew uninstall binutils && make clean && make

After I did this, wget did not work with the following error.

dyld: Library not loaded: /usr/local/opt/openssl/lib/libssl.1.0.0.dylib
  Referenced from: /usr/local/bin/wget
  Reason: image not found
Abort trap: 6

probably due to uninstalling binutils

brew update && brew upgrade did fix it for me.

I had the same problem, and neither of the solutions above worked for me.

I believe the reason this problem came up for me was because I had compiled the Makefile in another computer (ubuntu 16.04) and then transferred the whole folder over (with added files, scripts, etc.) to a MacOSX and tried to compile from the same Makefile.

The solution was to copy the repo again in a separate directory, and then make from that clean directory.
