Hello,

 

I'm trying to use Xcode (version 10.1) for cplex (version 12.6) in mac high sierra but having some problems to build my program.

I have read the two threads:

I did :

1. In Build Phases, import IOKit.framework, CoreFoudation.framework, libconcert.a, libilocplex.a, libcplexdistmip.a, and libcplex.a.

2. In Build Settings, the Header Search Paths, include.../IBM/ILOG/CPLEX_Studio1262/cplex/include, and .../IBM/ILOG/CPLEX_Studio1262/concert/include;

the Library Search Paths, I set .../IBM/ILOG/CPLEX_Studio1262/cplex/lib/x86-64_osx/static_pic, and .../CPLEX_Studio1262/concert/lib/x86-64_osx/static_pic.

3.Other C and C++ Flags some flags I found by running makefile in command line:  

 

.

 4. other linker flags, I added some flags I found by running makefile in command line:

I always get the errors as below. It seems that some people had the same problems, but i just can't make it work using the suggested methods in earlier threads. I really appreciate if anyone can help! Thank you!

Do things work any better if you do *not* put -stdlib=libc++?

Also, can you go to your CPLEX installation directory cplex/examples/x86-64_osx/static_pic, run 'make blend' there and show the output here?

Can you please try -stdlib=libstdc++ instead of -stdlib=libc++ (note the additional 'std' in libstdc++!)?

One of the main issues probably is that you are using a pretty old version of CPLEX with a rather recent version of MacOS. Is it an option to switch to a more recent version of CPLEX? For example 12.8?

In any case, the first you have to make sure is that your compiler and linker command lines used by XCode look the same as the one printed when doing 'make blend'. Maybe it is a good idea to start a new project that with the source code of blend.cpp and try to get that going?

Finally, I found this thread. It explains part of your issues and seems to indicate that maybe what you are trying to do is not (easily) possible with XCode and CPLEX 12.6 (because XCode has dropped support for some old things). If you cannot switch to a more recent version of CPLEX then I suggest you ask your question on an XCode forum. CPLEX should be no different than any other third party library that still required libstdc++ (instead of libc++). Note that more recent versions of CPLEX are build with libc++ as expected by XCode.

Hi Daniel,

I tried Cplex 12.8 and it is working now!

Thank you so much for your detailed explanation. You really helped me!
