[Dip] Branch-and-Cut-and-Price

[m noorizadegan]

Hi Ted,

I also noticed that dip is built for i386-apple-darwin11.3.0.
On my os x (or new clang++) it is x86_64-apple-darwin15.2.0.
Is it possible that the problem is due to this?

Best,
Mahdi

If you just build with default options (no arguments to configure) on a modern version of OS x, it should use clang and you should have no problems. If you need gcc for some reason, then I would suggest using the version provided by homebrew.

I've seen that error before, but it's pretty generic and can be any number of things. Would you mind posting some more details to the mailing list? It's always good to have these things archived in case others have the same problem. Details would include such things as the exact sequence of command you executed (what arguments you gave to configure), clang version, OS X version, etc. Eventually, I may ask you for the config.log file, but let's get the basics down first.

It is much easier to work, can be called through a modeling language, and provides many of the same capabilities as BCP with a much lower burden on the user. Let me know if that looks like it might suffice. I'm happy to provide more details and point you towards materials that would help you get started.
