ld linking error while compiling z3

Question

I met the following error while compiling z3. It seems to be an error for ld. I wonder what I can do to make it compile. It is a problem from the opt branch in git. I am on iMac with OS X 10.9.2 (13C1021) I am with xcode Version 5.1.1 (5B1008) with xcode-select tools installed to version 2333. I use port with version 2.2.1 with ld installed. The problem seems to be a linking problem. I am using 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

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

Another possibility is that ld was depend on llvm 3.3 rather than llvm 3.4. The problem was solved after updating ld.
