How to compile Gurobi C++ interface in Mac OS X 10.8.5 with latest Xcode

[Shayan]

Hi everyone,

I tried to compile my C++ Gurobi code which was compiled in my old computer but when I tried to compile it in my new mac book it does not. It seems that Gurobi does not work with C++11. I wonder if there is any solution for it? How can I compile with old C++ compiler?

Thanks.

C++ 11 is not supported.

Yeah I know. I'm just asking if there is a way to use a older C++ version in Mac OS 10.8.5 to compile Gurobi?

Hi Shayan,

can you post the error message that you get? You said the code compiled on your old system, which specs did it have?

Best regards,
Jakob

Hi Jacob,

For instance when I try to compile one of the examples from Gurobi website: "diet_c++.cpp" I get the following errors:

I use terminal with following command:

g++ diet_c++.cpp 

Thanks.

[Greg Glockner]

This is a linker error. Look at the Makefile in the examples/build subdirectory.

[Shayan]

Yeah it worked. Thanks a lot.
