Hi all,

I run into a cplex cpp compiling error after updating my OS to Mac OS 10.9 Mavericks. Similar problems also happen to python, but c files works fine. Does anyone have a clue what happened? I am using CPLEX 12.5.1. Thanks!

Best,

#CPLEXOptimizers

What compiler and which version do you use? In case you do not use g++ yet, could you please try if things work better with g++? Could you please also show us the error messages you get?

Here is my g++ version:

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1

Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)

Target: x86_64-apple-darwin13.0.0

Thread model: posix

 

Here is the error message I got when using the Makefile provided by CPLEX. I am trying to compile CPLEX examples in .cpp:

 

make all_c

The issue is that with the maverick release Apple has switched from libstdc++ to libc++ as the default C++ library (both are present, just the default is changed). On OSX the earliest release CPLEX supports is 10.7, thus CPLEX uses the default for that platform (indeed, we had no way of knowing that Apple will change the default). So all you need to do is to edit the Makefile and add "-stdlib=libstdc++" to both CCOPT and CCLNFLAGS.

#DecisionOptimization

It should not matter where exactly you put the -stdlib=libstdc++. You need to specifiy this without the quotes. Please note that you not only need this for the linker but also for the compilation step.

I suggest that you edit the Makefiles shipped with CPLEX as suggested by Laci. Then build the blend executable:

cd cplex/examples/x86-64_osx/static_pic/
make blend

This will print out the commands used to compile and link the files. From there you can easily pick up the required flags as well as their order.
