Ld when compiling z3

Question

When compiling z3, I met the following error. This seems to be a bug for ld. I wonder what I can do to compile it. This is a problem from the opt branch in git. I'm on iMac with OS X 10.9.2 (13C1021) I'm on xcode Version 5.1.1 (5B1008) with xcode-select tools installed on version 2333. I'm using a port with version 2.2.1 with ld installed. The problem seems to be related to the binding problem. I use the link loader as: ld64 @ 136_2 + llvm33 (active) My gcc is gcc (MacPorts gcc48 4.8.2_0) 4.8.2

Thank you very much!

Answer 1

This is because we used the port and installed gcc and ld and other packages.

Another possibility is that ld depended on llvm 3.3, and not on llvm 3.4. The problem was resolved after updating ld.
